General information

Broiler cross Cobb-700


Especially popular breeds of poultry, which have high rates of meat and egg productivity. These include broiler Cobb 700. Its content does not require a lot of money and labor, and also brings a good profit.

Cobb 700 Broilers Make Good Profits

History of

The Cobb 700 broilers are a hybrid breed that appeared as a result of crossing chickens that are similar in genetic code.

Having crossed the Rhode Islands, New Hampshire, Plymouthrocks, Cornish and Kuchinsky anniversary birds, the employees of COBB-Vantress received a unique breed. They also deduced Cobb 500 and Cobb Sasso.

Culling chicks with deviations in appearance led to the emergence of the purest breed. Her breeding are engaged not only in Europe but also in Russia. Like every hybrid, Cobbam was always difficult to cope with the continuation of the genus.


The body of the bird is massive, covered with white feathers without impregnation of other colors.

The wings seem too small, the neck is long, the small tail is slightly bent inward. Legs strong, long, yellow. The beak is also yellow, slightly bent down.

The difference between the Cobb 700 and the Cobb 500 is insignificant. The first one has a bigger breast, less fleshy legs. The head is smooth and scarlet. Straight small comb has a scarlet red color. Beard and earlobes of the same color. The eyes have a yellow or orange-yellow tint.

Meat and eggs

The big plus of the birds of this cross is their productivity. Characteristics of the cross Cobb 700 indicates high rates in weight gain, the Cobb 500 grows rapidly, but its size is smaller. In egg production, the cross has no equal in comparison with other hybrid varieties. Particularly productive are broilers that have undergone a careful culling.

The level of meat productivity is noted monthly:

  • 1.5 months - in females body weight reaches 1.5 kg, in roosters - 2 kg,
  • 2.5 months - chickens gain up to 4-4.2 kg of weight, roosters - 5 kg,
  • every week, broilers gain from 50 to 80 g before the age of 9 months.

Egg production in chickens starts from six months. While the body weight is growing, the eggs have a different weight - from 48 to 61 g. After the 9th month of life, each egg product reaches 63-71 g. The egg production remains at a high level until they reach the age of 2 years. The description of eggs does not differ from the standard for this variety - they are white, oval in shape, the shell is of average density.

Egg production in chickens Cobb 700 begins with six months

Rearing chicks

The females of the hybrid Cobb 700 breed have an unexpressed maternal instinct, so the chicks hatch in an incubator.

For hatching chickens, it will be necessary to buy high-quality eggs of this breed at specialized centers or poultry houses. Roosters and chickens of this cross-country at home are not able to reproduce a large number of eggs for hatching.

Purchased chickens at the age of 1-1.5 weeks do not tolerate the stress caused by the move. Because farmers are recommended to put the brood in the incubator. Free access to food and drink, constant and stable lighting will help birds adapt and survive the risk of death from stress.

If the broiler chickens of the Cobb 700 cross came from a domestic incubator, they are given a place to sleep and feed. Farmers should follow these rules:

  • the place should be dry and ventilated, with deep bedding,
  • the light for chicks is on for the first 10 days,
  • in the first days, the temperature is maintained at 27-34 ° С, after 14 days it is lowered every week by 2 ° С,
  • the humidity inside the chicken coop for chickens should reach 65%, after 10 days - 70%,
  • up to two weeks of age food and water is served at least 8 times a day, then 5 times a day,
  • required intake of vitamins and timely vaccination.

Maintenance and care

For broiler chickens Cobb 700 is characterized by unpretentiousness in food and content.

They do not require a lot of free space for walking, and therefore the best way out will be to organize a livestock habitat in a closed henhouse or cages. There is a maximum of 10–12 individuals per m².

The room should be warm - above 14-16 ° C. Airing is useful for the prevention of infectious diseases, but excludes drafts. The litter is laid loose, deep, changed every week or more often if it gets wet quickly.

Feeding broilers is associated with the characteristics of the breed:

  • ten-day-old chicks feed feed mixture for starter rearing,
  • feed for growth is used for livestock up to 22-24 days of life,
  • before slaughter, broilers are transferred to the finishing mixes of feed,
  • Birds are given green forage — nettle, dandelion leaves, cabbage, vegetables,
  • mandatory vitamin supplements that support the body of birds,
  • individuals provide clean drinking in large quantities - representatives of this breed are often thirsty.


The characteristics of the Cobb 700 hybrid include many positive properties: high immunity, good survival, high body weight, good performance of egg products. This cross grows better on special industrial feeds, and masters, made with their own hands, should be diverse. Birds are ready to be slaughtered at an early age, which makes it possible to grow several flocks during the warm season.

The origin of the cross COBB-700

Many poultry farmers have heard of such mysterious names as COBB-500, COBB-700, ROSS-308, ROSS-708 and so on. All these designations are united by the fact that they refer to broiler chickens obtained in certain factories as a result of a series of interbreeding. The first letters in the name are not an abbreviation or some other mysterious code, but the name of the enterprise at which this cross was obtained.

Chickens cross COBB-700 were bred in England

Cobb is an English company, which in its time gave many examples of excellent birds, obtained through careful and thoughtful selection. Such well-known breeds as Rhode Island, New Hampshire and others took part in the experiments on early cross-breeding.

The predecessor of the KOBB-700 cross is the KOBB-500, which for many years was considered the most productive and profitable option, which was preferred by many poultry farms. COBB-700 in many of its characteristics is the successor of its predecessor - more advanced and productive.

The advantages of cross

Why do many poultry farmers prefer the cross country COBB-700? To answer this question, you need to consider the main characteristics of these broilers:

    homogeneity. This quality means that if you are purchased by young of the same age, then all the birds develop at a time, developmental delays and underweight are very rare for this cross. This circumstance allows you to slaughter broilers on the same dates, which greatly simplifies the process

The young of this cross ripens at a time

Most poultry farmers slaughter chickens as early as two months

Thanks to good health, KOBB-700 cross country broilers quickly adapt to many conditions.

Disadvantages of cross

Like any other breed, COBB-700 has its drawbacks, which the poultry farmer must be aware of in order to more intelligently plan the content of the broilers. By cons KOBB-700 decided to include:

    low egg production rates. It should be remembered that the cultivation of broilers is focused primarily on obtaining high-quality meat. Therefore, the high egg production was not laid genetically and was not reflected in the layers of this cross (like most others). On average, a week from one female you will receive two eggs. This circumstance makes the breeding of broilers with the aim of obtaining eggs is not the most profitable undertaking,

Egg production rates are not the strength of chickens COBB-700

Broilers KOBB-700 are not suitable for breeding offspring in a natural way.

Meat direction

In obtaining high-quality meat in fast terms this cross, in fact, almost no equal. As already mentioned above, for a month and a half broilers gain weight in two and a half kilograms. If you wait another two or three weeks, then the weight of the males will reach five kilograms - it is this condition that the poultry farmers wait for in order to get the most meat at the lowest cost of feed.

Meat of broilers KOBB-700 is in demand on the modern market

Further broiler farming does not seem to be profitable, because after two and a half months, the speed of their development decreases markedly, while the chickens' appetites only grow. Moreover, growing up negatively affects the taste of the meat itself, so it’s better not to experiment with the optimal slaughter age.

Egg direction

Despite the fact that broilers of COBB-500 and COBB-700 crosses are not designed to take down a large number of fertilized eggs, some farmers use them in this direction. The females of this cross-country begin to race approximately in half a year. The eggs of young hens weigh about 50 grams. However, as mentioned above, it does not make sense to wait for high egg production from the meat-oriented cross.

If you want to regularly receive eggs from females, you should think about purchasing chicken eggs.

You should not also forget that it is impossible to get the corresponding offspring from hybrid lines. If you want to be engaged in breeding chickens of any cross-country manually, then you expect great disappointment. The descendants of hybrid birds rarely catch up with their parents in terms of productivity, and sometimes they are completely in poor health.

To make the right choice of chickens you need to compare the characteristics of various breeds and crosses. On the productivity of other broiler crosses we describe below.

Broiler meat breeds

Conditions of detention

KOBB-700 broilers are successfully grown both in private small farms and at poultry farms. Therefore, even if you are a beginner poultry farmer, then this cross may perfectly suit you. Most of the difficulties arise with the care of newborn chicks, because they are the most fragile and susceptible to various infections. As they get older, broilers grow fast and require less and less attention.

The content of broilers differs little from the content of other breeds of chickens.


The first days of life are smoking are a real turning point, since most of the deaths of broilers occur precisely in this difficult period. In some cases, the poultry farmer can do nothing with the death of one or two individuals - such unpleasant episodes are taking place.

However, in most cases a person can control the health and well-being of chicks. For this you need to consider several decisive factors:

    air temperature. In the first weeks, the farmer needs to prepare for constant monitoring of the temperature, since it will have to be changed often. The first seven days the brooder temperature should be at least 33 degrees, the second week at least 30, the third at least 27. By the end of the month, the chicks should be comfortable at 18-20 degrees,

The temperature in the brooder decreases as the young grow up.

Feeding the chickens should be balanced to avoid intestinal blockage.

Adult content

Since COBB-700 is grown for meat, walking cross representatives is not recommended. As a rule, such birds are not released for walking even during warm, favorable seasons. In the overwhelming majority of cases, these individuals are contained in cages, however, if desired, they can be bred in the hen house by the floor method.

Flooring broiler content is often practiced in private farms

As for the requirements for the content of mature broilers, they differ little from the requirements for the content of other chickens. It should be borne in mind that, with all its unpretentiousness, representatives of the breed are distinguished by a rather weak immune system and are predisposed to all sorts of infectious diseases.

Coop Requirements

In order for broilers to be comfortable in the hen house, it must meet several basic requirements:

    moderate air humidity. High humidity contributes not only to the spread of cold in cold seasons, but also the reproduction of pathogenic bacteria. To regulate humidity, the chicken coop must be equipped with windows and a simple ventilation system consisting of flow and exhaust pipes,

Air humidity directly affects the health of birds in the hen house

Overcrowding coop encourages birds to conflict and peck each other

Selection of the correct diet is very important, because the state of the future meat, its texture and taste, largely depend on the food that the broiler consumed. In poultry farms, broiler feeding is usually practiced with compound feed, since all the necessary nutritional elements are collected in such feed.

Private farmers feed chickens in different ways. Someone prefers mixed feed, someone prepares food for birds with their own hands. It is undesirable to combine the two types of feeding, as this may cause digestive problems in broilers.

Feeding broiler depending on the period of its development

By the way! If you want to feed broilers with their own food, make sure that it contains mineral supplements that strengthen the body of birds. As such additives, chalk, crushed shells, table salt are used.

Converting broilers to feed requires the use of several feeds depending on the age of the bird:

  • chicks up to one and a half weeks are given starter feed,
  • for chicks up to three weeks, the growth variant of the compound feed is ideal,
  • from the third week up to slaughter the final feed is fed to the chicks.

Meal frequency

Particular attention should be paid to the frequency of feeding. The smaller the chick, the more often it should be fed, while the portions should be very small so as not to overload the gastrointestinal tract of the chicken. The first seven days feed chickens at least seven times a day. In each subsequent week, the number of meals is gradually reduced by two meals. Broilers that have reached the age of one month should eat twice a day - in the morning and in the evening.

The number of servings eaten per bird per day depends on the age of the broilers.

Of course, broilers are peculiar to all the same diseases that all other chickens are subject to. However, there are a number of diseases that occur precisely in representatives of the crosses. The most common diseases among broilers are presented in the table.

Description of the cross Cobb 700

Cobb-Vantress is constantly working on the development of new productive crosses, their products are famous all over the world. The old crosses are replaced by new ones that are more productive. The Cobb 700 is more productive than the Cobb 500 broilers. The yield of meat products is much higher. Externally, the broilers of the new cross looks the same as their older brothers. The body is a strong constitution, muscles of massive form. Chickens have a large amount of pectoral muscles. Compared with other parts of the body, they occupy a large part. In terms of performance, the breast far exceeds the parameters of the thigh muscle. The plumage in chickens at the age of two weeks is white. The skin is yellowish, which positively affects the presentation of the carcass.

Externally, the bird has a red face, the ear lobes and scallops have the same color. Cobb 700 cross country broilers must comply with a specific standard. Chicks with deviations are subject to rejection. Undesirable parameters include: the presence in the plumage of other colors than white, the weight gain by day does not correspond to the norm. During the entire period of cultivation, a weakened bird, a sick, inferior bird and also a bird that lags in growth and development should be culled. For a farmer, growing a cobb 500 or 700 grow will be cost effective. Since the output of products will pay back the cost of feeding during the growing period. In breeding broilers, the following productive breeds of chickens were used: Plymouth, Jubilee Korni, Corniche, Rhode Island and New Hampshire.

Productivity of broilers Cobb 700

Like all past crosses, a hybrid was created for faster production of finished meat products. This cross is effective in getting brisket. Getting the breast from broiler chickens of the Cobb 700 cross is effective, since the mass fraction of the yield of brisket exceeds the cost of feed. The result is a large amount of dietary meat at a low price. This cross, as well as the Cobb 500, is a hybrid and the chickens obtained from the parent stock cannot breed. Eggs can be given only by the parent flock. Chicken broilers can not bear eggs. Growing a parent flock is different from growing broiler chickens for meat. When growing, you must comply with the necessary standards developed by Cobb-Vantress.

Growing a cross Cobb 700

Since the cultivation period is only 2 months, it should be understood that it is impossible to contain these cross as ordinary chickens. This applies to all high-performance crosses, as they are designed to produce large quantities of meat in a short period of time. Если цыплята будут выращиваться как обычные яичные курочки, то не стоит ждать от них колоссальных результатов. Всегда следует понимать, что высокоэффективные кроссы не выращиваются как обычные куры, а растут только определенной количество времени.Also for such crosses required appropriate quality feed. Feeding this bird with grass, grain and other feed for ordinary chickens will not lead to good results. Growing can be carried out with the purchase of daily young or by self-incubation. With both methods, you need to carefully approach the choice.

Chickens must be mobile, the navel is healed, the behavior is active, the cloaca is not contaminated. Buy better from trusted sellers. The same goes for eggs. The seller must show you the necessary certificates of conformity of products. Growing this productive birds is no different from Cobb 500. Pepper by planting daily young stock premises should be prepared. Namely: warm, lay bedding, put water at room temperature and pour broiler starter feed into the feeder. The temperature should be within 33 degrees as it grows down to 27 ° C, it is measured at the level of the litter. Broilers are grown only indoors without the use of walking. It is necessary to control the humidity of the air, temperature, lighting and in no case prevent drafts and gas pollution. Chickens are raised to two months. They periodically change the litter if it is wet and heavily soiled to prevent the spread of infection and injury to the limbs.

If the farmer has the opportunity to incubate, then this will require the purchase of an incubation egg on which the production date and the marking of the corresponding cross must be indicated. Before laying the eggs in an incubator, they are heated to 25 ° C. The temperature varies from 37.6 ° C to 37.8 ° C. During incubation, monitor humidity and temperature.

External features and physique

Broilers chickens are distinguished by a massive body, their breasts are especially wide. Cobb has a strong, long neck, straight back, short, upturned tail. The wings of the bird are tightly pressed to the body, in relation to it are disproportionately small, the paws are powerful, non-feathering.

The straight comb, earrings and leathery area around the eyes are bright red, the eyes are yellow, the beak is strong, slightly curved. Chickens have yellow plumage, which with the growth becomes snow-white. Interspersing other colors in color is a reason for culling an individual.

Precocity and taste of meat

At the age of one and a half months, broilers can be slaughtered, their weight at this point is 2.5 kg in females, 3 kg in roosters. Experienced breeders prefer to wait for the peak weight gain, which falls on the age of 2.5 months: the weight of the rooster at this time - from 5 kg, chicken - from 4 kg. There are such taste characteristics of meat: juicy, soft, with a pleasant yellow skin.

Egg production

Sexual maturity of females begins at the age of six months. The average weight of the first eggs is 52 grams, later, as the hen grows, the egg reaches 70 grams of weight.

The productivity of the hen lasts up to two years, for this it is transferred to grain nutrition. Chicken will sweep about once every three to four days.

Egg Incubation

Eggs from Cobb's parents will not give offspring with the same characteristics, since the breed is hybrid. For breeding, they take eggs at poultry farms and breed them in an incubator: chickens do not have maternal instinct, laying eggs does not make sense.

Purchased from serious manufacturers, certified eggs have already passed all stages of rejection, each has a seal of quality on the shell. Before the incubator, the material is placed in a kind of storage with a temperature content of 25 degrees Celsius.

Then put in an incubator where the air temperature is 37 degrees. The subsequent stages are carried out in accordance with the operating conditions of the model of the incubation device. You need to carefully monitor the parameters, turn the eggs.

Video: incubation of chicken eggs After hatching, the babies are allowed to dry out at a temperature of 33-35 degrees, then sent to an equipped box for further maintenance. The temperature of the content as they grow decreases.

Feeding ration

To bring out broilers, you should purchase production fodder, designed specifically for the needs and characteristics of meat breeds. For feeding without compound feeds, special knowledge, special additives, mixes, calculation of the balance of all nutrients are needed.

Industrial feed for broilers give the following scheme:

  • up to ten days - starting,
  • up to 22 days - growth,
  • before slaughter - finish.

In the house

The bird house must meet the norms of the density of the population of the bird - 12 individuals per square meter. A few days before the poultry settlement, the room undergoes a complete disinfection volume, a deep bedding of sawdust and straw is laid. It should be dry and loose.

The temperature of the content under the condition of measurement on the litter should not be below 27 degrees, from one month to slaughter - 14 degrees. Humidity from the first days of 65%, after successful adaptation rises to 70%. The room must be ventilated, musty air is an ideal breeding ground for bacteria. The first two weeks of chickens kept around the clock in the light, at two weeks of age, reduce daylight hours to eighteen hours.

Temperature conditions and humidity at the cellular content remain the same as in the house.

Cells allow you to save space, because they can be arranged in tiers, save on litter material. The density of a single cell with a floor size of 0.5 m2 will be ten individuals.

What kind of breed?

Cobb - 700 are broilers bred specifically for meat production. They have optimal muscle mass gain characteristics. An adult individual in 1.5 months can reach 1.5 kg.

Chicken of breed Cobb-700

In Russia, Cobb - 700 are widespread. They have many advantages and few drawbacks, so if you are planning to start meat broiler farming, look closely at this breed.

Breed of broilers Cobb-700 has won the trust of farmers in Russia due to its winning characteristics:

  • she has one of the highest rates of weight gain,
  • she is not whimsical in care
  • good chick immunity protects them from infections and diseases,
  • Arbor Acres hens have a high egg yield,
  • picky about food, eat what they offer.

Breed description

On the Internet you can find the standard description of the Cobb-700 broiler breed.

The Cobb - 700 broiler is a large and muscular bird. If her predecessor Cobb - 500 had muscular and large hips, then the representatives of this breed put emphasis on the breast. It is large and prominent in these birds.

Chickens of broilers Cobb-700

Broilers of Arbor Eikres breed from yellow chicks grow into white chickens with a bright red beak. Their legs are long and massive, yellow in color.

The carcass itself when plucking has a yellowish tint, so valued by the consumer. This skin color of a bird does not depend on the substances it consumes in food and is transmitted genetically.

Care features

Despite all its advantages and lack of care, Arbor Aykres must be monitored.

The first stage of chick adaptation to new habitat conditions is very important. When moving to a new place of residence, the chicks are under stress and can get sick. Therefore, when moving small broilers to an incubator, like all other breeds, a natural decline in livestock can be observed.

Incubator Eggs

If you are an experienced farmer, you can try to breed Arbor Acres chicks on their own. So you will avoid livestock losses from the transportation of kids Cobb - 700.

The first 10-15 days of the nestlings of the Cobb - 700 breed must be kept in an incubator. They require a constant air temperature - at least 30 degrees Celsius. In the future, it can be lowered, but not sharper than 2 degrees per day. Adult birds are allowed to hold at temperatures above 15 degrees Celsius.

Incubator chickens

In the incubator, chicks should have constant access to food and drink.

Adults do not require free range, Arbor Acres can be kept in individual cages all the time.

On the Internet you can find many videos and photos of materials, tips and descriptions for the care of broilers Cobb - 700v Rosiii.

Feeding broilers

Since the main characteristic of the Cobb-700 broilers is a rapid increase in body weight, these birds need a constantly balanced diet.

It is better if it will be mixed. It maximally balanced all the necessary nutrients, vitamins and minerals.

Up to 21 days of life, as experts and reviews of experienced farmers say, it is better to use compound feed such as “Start”. After the broilers are transferred to the feed - "Growth". At the final stage, they feed on the Finish compound feed.

The description of the Cobb-700 broiler states that with proper nutrition they are ready for slaughter after 1.5 months of cultivation. Their body weight by that time should increase to 2.5 kg.

Small chicks up to 10 days of life are fed 7-8 times a day. Maximum break without food - 6 hours. It is necessary to remember that birds consuming mixed feed are drunk twice as much as feed. Fresh and clean water should always be available. Dehydration is dangerous for broilers.

Adult birds are fed up to 5 times a day with appropriate feed.

You can opt for the mixed feeding system of broilers Cobb - 700 breed. Then you can enter various natural products in the diet of chicks, in accordance with their age norms and restrictions.

Broiler Cobb-700 in Russia is widespread. It should be attentive when buying chicks. Often for the breed Cobb - 700 give a completely different breed of chickens. One should not expect such characteristics in development from them.

Breed popularity and its external features

KOBB broilers are popular all over the world. They gained their popularity due to high growth rates and productivity. More recently, the “500” hybrid was considered the most effective cross. The emergence of a new model line was taken by farmers around the world as an improved broiler. So it happened. Hybrid chickens are the descendants of the most productive breeds of chickens ("New Hampshire", "Rhode Ayledskie", "Plymouthrok", etc.). Representatives of this breed immediately raised the productivity index a few points above their predecessors.

Such broilers are little different from other COBBs. They are equally strong and massive, have white plumage and yellow carcass. The description of the 2 hybrid breeds still has some differences. The seven hundredths have a wider fleshy breast, and their hips are narrowed. They can be seen on the PHOTO. The predecessors are distinguished by more modest anthropometric parameters.

According to the farmers who breed seven hundred COBBs, it’s easy and profitable to keep these birds. The main thing is to sort chickens correctly: discard pigmented, weak and lagging masses of birds. One individual with proper care and feeding at the age of 2 months can reach 1.8 kg. This figure is the highest in modern farm production and they have no direct competitors. Chickens are an ideal option for getting not only meat, but also eggs, while the cost of feed is minimal.

Breeding benefits

At seven hundred cobbs there is an ideal ratio of costs and profits, not only for production purposes, but also at home. This is one of the advantages of a hybrid, in addition to which poultry farmers also distinguish:

  • high weight gain
  • good egg production
  • easy care
  • strong immunity to infectious and viral diseases,
  • unpretentiousness in food.

Such advantages make cross one of the most popular for breeding. The less effort and money spent on the maintenance of these birds, the better for their owner. In addition, the end result - tasty and healthy meat and eggs. Russia, like other countries, has long appreciated the quality of these products. Even when breeding at home, chickens will surprise their host by showing rapid growth and productivity.

Cross 700 has almost no flaws.

One of the most significant - this is the similarity with the five hundred Cobb. It will be easy for an experienced farmer to determine where the 700th hybrid is, and where its predecessor is. But to all novice poultry farmers such a task may be too tough. Especially often people make mistakes when buying young stock. Chickens broilers are almost identical to the five hundredth age mates, and the first external noticeable difference appears only after 2-3 weeks from the birth of the chick, when it acquires a more powerful breast, and its skin on the head becomes bright and red.

Content Features

Such a characteristic of the breed, such as high egg production, will not be achieved without the organization of proper and effective bird care.

Problems can begin as early as the first day after the acquisition of young animals. Changing the main habitat often causes stress in chickens, and this affects the state of their immunity. Broilers can get sick, which will lead to their partial death, so the farmer needs to put the chicks in the incubator. This procedure has its own characteristics, which include:

  • long maintenance in the incubator up to 15 days,
  • unhindered access to the trough and watering system,
  • constant maintenance of temperature in the incubator 27-30 ° С,
  • from the tenth day it is necessary to lower the temperature by 1 ° per day.

Chickens do not tolerate cold. The minimum temperature of their content is 16 ° C. In addition, for their growth and productivity, it is important to provide hybrids high humidity. Other care features are also important. So, COBB-700 does not require walking and must be kept in cages or small chicken coops. On 1 square. m can account for up to 10 birds. Many farmers for such a hybrid breed select cells based on the stated breeding characteristics (40 kg weight / sq. M).

Despite their strong immunity to viral and infectious diseases, birds require constant heat and lack of drafts. Cleanliness must always be maintained in the hen house, and their feeder and water bowl must be filled with food and water. It is also important to equip the place of detention with ventilation. Litter fumes are toxic and can cause the appearance of disease and the death of birds.

Features of the diet

Characteristics of high growth are closely interrelated with feeding parameters. The task of the poultry farmer is to provide Cobbs with a balanced diet. Unpretentiousness in eating these birds is the advantage of their content. But in order for broilers of this breed to gain weight quickly, it is necessary to give them industrial feeds. Nutrition feed has its own characteristics, which include:

  1. The need for feeding chickens in the first 2 weeks of their life starter feed. The best option - eight meals.
  2. From the 15th to the 24th day, the hens should be fed with growth feed 5 times a day.
  3. After 24 days the finishing feed is used.

Growing healthy and massive chickens without acquiring industrial nutritional feed is very difficult. Only experienced poultry farmers decide on such measures, independently preparing mash. It is necessary to calculate the mass of each component in terms of energy value. This feed includes grains, greens, dairy products, premixes, chalk, etc. With proper feeding after 2 weeks, the chicken should weigh 1.5 kg. Slaughter is carried out at the age of 1.5 months, when their mass reaches 2.4-2.8 kg.

We must not forget that the crosses require constant access to the drinker. Novice farmers need to know that a bird cannot live without water for more than 12 hours. The maximum safe break is 6 hours. The drinking bowl must be kept clean and constantly filled with fresh water. If this is not done, birds can get sick, which will also affect the decrease in productivity and lead to the death of part of the population.

What you need to take care

Breeding seven hundred cobbs may seem difficult to novice farmers. In order to always act correctly, it is necessary to effectively use the experience of other poultry farmers who have obtained good indicators of growth and productivity of their livestock. Some of these reviews concern nutrition.

Some farmers recommend mixing feed with greens, which is an additional source of nutrients. Other poultry farmers prefer not to shy away from the recommended norms and pay more attention and time to clean the cages. All agree only on one thing: if there is a desire to acquire seven hundredth cobbs, you must first install an incubator, which will help not only to grow healthy chickens, but also to support the number of contained heads.


Feathered Cobb 700 surpasses many fellows with its performance. It pleases breeders, so the breed is popular everywhere.

The first slaughter begins at 1.5 months, when the weight of chickens reaches 2.5 kg, and males approaches the mark of 3 kg. But it is better to wait for the maximum weight gain, which comes at the age of 9 weeks.

At this time, the female gains 4 kg, and the male 5 kg and more. After that, it is advisable to slaughter all the livestock in order to maintain the improved quality characteristics of the meat.

Some poultry farmers want to get egg products, but do not want to breed a separate breed of chickens. Cobb 700 in the first 2 years of life copes well with this task. They reach sexual maturity at 6 months and bring the first eggs around 48–55 g. When the hen fully grows, the weight of one egg reaches 70 g.


Самостоятельно разводить Кобб 700 не получится, так как бройлеры являются гибридами. Из яиц, полученных от родительских особей, появятся цыплята, породу и производительность которых предугадать невозможно. Поэтому яйца покупают на птицефабрике и разводят с помощью инкубатора.

Putting them under the Cobb 700 chicken will fail, as the birds lack a brooding instinct. But with the observance of the rules for using the incubator, the percentage of hatching is high.

If you do not want to engage in the breeding of the baby from the egg, you can buy day-old chickens at the poultry farm. But chances of reducing the number of chickens in the first day of life.

The reasons for this phenomenon:

  • Wrong mode of keeping and feeding,
  • Adverse transportation conditions
  • Adaptation to new living conditions.

All this is hard for the body of a hybrid chicken, so many individuals die. The farmer needs to prepare the nestlings in advance and transport them carefully, avoiding drafts, shaking and loud noises.

Broiler Cobb 700 is not bred like ordinary chickens, only with the help of a specialized device. There are a number of rules, the observance of which gives a high chance of getting more offspring.

Here are some of them:

  1. Buy eggs from a reputable supplier with a good reputation, where the seller has all the certificates of conformity. At such enterprises, the shell of each future chicken is marked with a seal.
  2. Prior to the procedure of removing the air temperature in the room where the incubation material is stored, raise to 25 degrees. Then the future chickens are placed in an incubator warmed to 37 degrees. Further, according to the schedule, all activities are carried out according to the model of the device used.
  3. It is important to monitor the observance of the correct temperature, humidity and turn eggs in time.

When the chicks hatch, they are given time to dry inside the device at a temperature of 33-35 degrees, and then they are planted in a prepared brooder. As children grow older, the temperature decreases.

Content of adult chickens

Broilers require special conditions and feeding schemes. Since the complete slaughter of livestock is carried out in the interval from 1.5 to 2.5 months, there is no point in releasing birds for free-range even in the summer season.

Comfortable conditions for the Cobb 700 look like this:

  • The content of the cell or on the litter without the possibility of walking,
  • One square meter of not more than 42 kg of live weight of a bird, that is, 5–7 chickens,
  • No drafts,
  • Temperature control is maintained at the level of 14-16 degrees.

Since the breeders' task was to get chickens with maximum productivity in a short time, scientists did not pay attention to the Cobb's immune system. Therefore, it is weaker than the parent breeds.

To prevent the loss of all livestock, maintain cleanliness in the hen house, avoid gas pollution of the room, monitor the temperature, humidity and lighting.

Caring for broilers with cage maintenance is easier than when birds are kept on a fork, therefore, this way of feeding is recommended to beginner breeders.

High-quality food hybrids - a prerequisite for the content, otherwise they will not show the expected productivity. Experienced breeders recommend buying industrial feed for broilers and meat breeds.

It is also worth adhering to the following diet according to age:

  • From birth and up to 1.5 weeks - starting feed,
  • From 10 to 22 days - growth compound feed,
  • From 22 days before slaughter - finishing feed.

Ready-made feeds contain a complex of vitamins and minerals that chicks need for normal growth and weight gain. And also do not forget about clean water in drinking bowls, as dry food often causes thirst in birds.

Advantages and disadvantages

To make a final decision on the choice of a hybrid, it is necessary to consider all its “pluses” and “minuses”.


  • High hatchability and survival rate of chickens,
  • Ease of content
  • Competitive meat quality characteristics,
  • Fast growth.

Poultry farmers note one drawback - the complexity of buying eggs. In Russia, at the poultry farms the complete replacement of the Cobb 500 with the Cobb 700 has not yet been carried out, despite the fact that there is a difference between them. Therefore, in remote areas of the country there are difficulties in acquiring incubation material and chickens.

Before choosing a hybrid as the basis of farming, it is necessary to examine the question of the compliance of eggs with the declared quality, so as not to run into scammers. The manufacturer must have all the official certificates that he presents to customers upon request.

If there are no such documents, it is better to refuse to purchase from this seller, since the probability of fraud is high. The rest of the experienced poultry farmers note that, subject to conditions of detention, broilers do not pose problems and show the declared productivity.
