Broiler weight table by day: calculation of weight gain, reasons for poor gain

Some breeds of poultry were bred by crossing different species to improve existing beneficial properties and create new ones that facilitate poultry breeding in industrial conditions and in households. You can find out the weight standards of a Cobb 500, Ross 308 or 708 broiler by day at home in the table below. This is necessary to understand how the bird develops and how suitable certain conditions are for growing.

Broiler growth chart by day

Daily weight gain plays an important role in the further development and growth of birds. Under normal conditions, a broiler should gain more than 65 grams per day (provided that the value varies depending on the sex and age of the bird).

Using this table of broiler growth by day, it will be easier to track its normal development (table):

10 days

The first weighing of chickens is recommended when they reach ten days of age. It is from this period of life that one can judge the further development of the chicken.

A healthy chicken at this age weighs on average 200 grams. Starting from this point, the weight of the broiler will begin to increase rapidly. Weigh yourself at least once a week, this will allow you to timely detect the cause of weight loss, if any.

1 month

How much should a broiler weigh at 1 month? It depends on many factors.

At one month of age, a healthy bird reaches 1.6 kg of live weight. If the weight is significantly below this mark, reconsider your options for keeping pets. It is possible that you made a mistake in the initial stage of cultivation. Correcting the feed and living conditions can improve the situation and allow the broiler to gain the required weight.

2 months

With proper care and nutrition, the weight of a broiler at 2 months is about 2.7 kg. Inadequate nutrition or poor living conditions can significantly reduce this figure.

At this age, chickens should be given as much greens as possible. To make birds grow faster, feed them grain mixed with crushed potatoes - this will avoid vitamin deficiency and enrich the body with important minerals and vitamins.

To ensure that broilers do not have a protein deficiency, feed them milk and curdled milk, but under no circumstances replace water with them.

Characteristics of the Cobb 500 breed

When describing Cobb 500 broilers, it should be noted that they are considered one of the most productive crosses. Cobb 500 chickens were bred specifically to produce the maximum amount of meat with a minimum growing time. By the age of 40 days, with proper care, you can get a bird weighing about 2.5 kg.

History of appearance

At the core of their origin, cobb 500 crosses are hybrids, since other varieties were taken as the basis for this breed: Plymouthrock, Kuchinsky Jubilee, Cornish breed, New Hampshire, Zagorskaya salmon, Pantsirevsky, Rhode Island.

Important! Due to the fact that the bird reaches readiness for slaughter in a little more than a month, it is possible to raise several generations at once in one warm season. This is very convenient for those who do not leave their birds for the winter.

The characteristics of the Kop 500 broiler breed make it the best of the meat breeds; this breed is grown all over the world: the USA, Russia, Hungary, Belarus, Ukraine and other countries in Europe and Asia. Still, the Czech Republic is considered the homeland, so Cobb 500 broilers are often called Czech crosses.

Appearance

It is easy to recognize a Cobb 500 bird by its appearance:

• always a white feather;
• powerful physique;
• wide back and chest;
• strong developed paws and legs with large amounts of muscle;
• a small crest of bright red color is characteristic of both females and males.

If a bird gets too angry, it can cause serious injuries. But, despite their power and strength, the breed is distinguished by a calm disposition; they are rarely the first to provoke fights.

On a note. Very often, Cobba 500 broiler chicks themselves suffer from relatives of a more aggressive nature, therefore, having introduced these birds into the house, you should make sure that they do not suffer while they are settling in.

The great advantage of this breed is its good presentation. The meat is white and the skin is yellow, which is not typical for other types of broilers. For example, Ross 308 and 700 or Hubbard breeds have a pronounced bluish tint.

The average weight of a newborn broiler chicken is 50 grams. Use this figure as a starting point if you are unable to weigh accurately. Please note that if a chicken exceeds its fellows in weight, then in the future it will be much larger than them. The same applies to lack of weight - if a bird after birth weighs much less than the average norm, then the weight of a broiler at 1 month will be less than that of the rest.

Norms of weight gain for bottle-fed girls and boys

At the moment, parents can rely on several tables that indicate the weight gain of the newborn by month, depending on the type of feeding.

More recently, pediatricians relied only on one table, developed by WHO more than 25 years ago. These values ​​were calculated based on statistics from infants who were predominantly formula-fed. But such children, as a rule, gain weight faster than their peers who feed on mother’s milk.

Below is a table of weight gain for a bottle-fed newborn.

How to determine the weight of a chicken

One of the most important steps for a breeder is regularly determining the weight of chickens. Weighing birds more than once a week will help to accurately determine weight gain and, if necessary, adjust feed.

When distributing feed, it is important to take into account how much food the birds received over the last 3-4 days in order to correctly calculate the scheme for the coming week.

Some tips for accurate weighing at home:

1. Weigh the chicks after placing them in the box. This will allow you to determine the average weight of one chicken.
2. It is recommended to weigh chickens at least once a week.
3. Try to determine the weight of the chicks before you feed them.
4. Each bird that comes into the box must be weighed. Don't forget sick or malnourished birds.
5. Use a high quality bathroom scale or canter.
6. Remember to count the chicks before each weighing.
7. Do not change the weighing method under any circumstances to make the data more accurate.

Basic rules of fattening

The acceleration of the growth of broilers is determined by the normal conditions of their keeping, as well as by a complete, balanced diet. Nutrition is provided first according to a frequent schedule, and then, as the chickens grow, the number of their feedings decreases, so it is important to know the approximate age of the livestock. A farmer does not always raise poultry from birth, but you can determine the age of broilers by external signs:

• one week - by this age the chicken’s wings have grown to the tail, but they still remain covered with down;
• 12 days – the chickens’ shoulders are covered with feathers;
• by 19-21 days of life, the crop, back and breast are covered with feathers. feathers on the tail begin to grow;
• at 4-5 weeks the first molt occurs, after which flight feathers appear on the wings;
• within 6 weeks the head and lower part of the body feather;
• By 3 months, the broiler has full plumage, which is ready to shed in the fall.

Considering the age of the broilers, you can adhere to the following feeding scheme, while not forgetting to weigh the birds.

The first 5 days after birth. This age requires maximum attention and care for weak chickens. Such babies should be fed at least 8 times a day (including at night) after an equal amount of time. Their diet should consist of 25% protein, which comes from boiled yolk, cottage cheese and corn grits. Food should be well ground.

The drug “Trivit” is a health and growth stimulator for chickens; it is better to give it in a course - 1 drop 4 times every 7 days. Weak chicks are temporarily kept separately from the rest of the population until they get stronger.

• 6-10 days. Gradually introduce roughage, cereals, and greens. The frequency of meals is 7-8 times, including one night feeding. You can give grated fresh carrots, at first no more than 5 grams per head, then increasing this amount to 20-25 if the chickens’ reaction was normal.
• Closer to 10 days of age, it is useful to introduce lime, shell rock, and small eggshells.
• 11-20 days. Nutrition is already reduced to 6 meals per day. It is good to mix bone meal into the diet and give boiled fish waste. Curdled milk or skimmed milk will improve the microflora of young animals.

21-30 days. The most important milestone when raising broilers, the weight of which must comply with the standards. The cereals are mixed with boiled crushed potatoes, and the broilers peck at the whole grain. Meals – 5-6 times a day. After 30 days, the bird can be completely transferred to an adult diet with 4 feedings a day before slaughter

It is important to add vitamin premixes to food, taking into account the dosage, and carefully monitor the health of the livestock

Throughout the entire growing period, weight gain must be monitored, if not daily, then at least weekly. This procedure makes it clear whether the bird is sick or whether mistakes are being made in the nutrition and maintenance of broilers.

You can learn how to raise broilers from the video.

Broiler is a meat breed of poultry in farmers' households. The most popular hybrids are:

The broiler reaches its maximum weight after 3 months. For this reason, the breeder weighs the chickens daily, controls their weight and calorie content of the feed. This way you can correct shortcomings in growth and get closer to the norm. A broiler growth chart will help you control weight gain.

Organizing poultry nutrition

Nutrition composition

During the first weeks of broiler life, the feed should contain at least 20% protein. After four weeks, replace it with a 19 percent protein feed. Most chicken feeds contain medications to prevent infections, so follow the care instructions before slaughtering birds and dressing the carcass to ensure there are no drugs in the meat.

Feeder

For convenience, it is recommended to use a special chicken feeder. At first, you can use half an eggshell. Over time, you will need to purchase a feeder from a specialty store.

Water

Provide broilers with constant access to fresh water. Use a drinking bowl for these purposes. Remember - the more chickens, the larger the drinking bowl should be and the more often it needs to be updated.

Causes of failure to gain weight

1. Low temperature. The room in which the chicks are located must be kept warm 24 hours a day. In the first two weeks, the chickens’ immunity is actively developing, so the temperature should be at least 30 degrees Celsius above zero. After 14 days, the temperature can be reduced to 25 degrees. Please note that Cobb-500 broilers may die in the first week of life if the temperature is significantly lowered.
2. Lack of light. In the first days of life, the light should be on most of the time.
3. Lack of calcium in the body of chickens. Poor growth can often be associated with poor nutrition.
4. Incorrect meal schedule. Often broilers do not gain weight due to insufficient nutrition. In this regard, the body functions only on internal reserves, the metabolism gradually slows down. It often happens that only a few chickens need additional nutrition.
5. Parasites. Helminths can affect the functioning of the digestive tract of chickens and inhibit the development of a growing organism.

Problem solving and prevention

Pay attention to the conditions in which you keep broilers. Avoid high humidity in the room. If possible, install a ventilation system. Use a few tips:

1. Install the oil cooler. Try not to skimp on the radiator, as more expensive models are much more stable. An alternative is to use an infrared lamp to illuminate and insulate the room at the same time.
2. Lighting plays an important role for the proper development of birds. To avoid problems with their immune system, try to keep the coop lit for 17 hours a day. However, the light should not be too bright. This irritates the chicks, since soft, slightly dim light is most suitable for them.
3. Use lamps with blue or red flux. This will create the required duration of daylight, which will have a positive effect on the development of broilers.
4. Ensure that your chickens' feed is of the highest quality. The composition must include minerals, vitamins and calcium. Compound feed is suitable for these purposes. It contains everything a growing body needs. When purchasing mixed food, make sure it contains protein.
5. To ensure that broilers always have enough calcium in their bodies, include eggshells and chalk in their daily diet. This is necessary not only for chickens, but also for adult laying hens.
6. To improve digestion, add crushed gravel to your food. This will help digest food and speed up the growth process.
7. Please note that chicks should be fed at least eight times a day in the first seven days. After a week, reduce your food intake to six times, and after another three weeks - to four. The food should contain greens, as they provide the chickens with essential vitamins.
8. As a preventative measure, add antibiotics and complex vitamins to your diet. Monthly examination by a veterinarian and timely vaccinations will reduce the risk of infectious diseases.
9. If broilers suffer from helminthiasis, add Nilverm to their food. The drug can be purchased at pet stores.

Home care rules

A broiler chicken requires more careful care than a regular laying hen. A warm poultry house and a clear daylight regime are important. The room is washed and whitened, drinking bowls and feeders are installed, lighting and heating are provided, and a thermometer is installed. A blanket of sawdust is placed on the floor. For the first 2 weeks, round-the-clock lighting and a temperature of + 30 degrees should be provided. Subsequently, reduce the temperature by 2 degrees per week to +22 °C. When the broilers are 1 month old, the daylight hours should be 14 hours, and the lighting should be turned off for 10 hours.

There should be no more than 13 heads per 1 m2. If the livestock is larger, the barn should be equipped with cages.

On a note. The floor in the chicken coop should always be dry and clean. Humidity can make the bird sick.

There are 2 growing methods:

• Intensive. Young animals are purchased throughout the year every 4 months.
• Extensive. The classic method is when poultry is purchased in spring and summer and raised until the autumn season.

Chickens are in the poultry house

The chickens are kept in the poultry house, do not go outside and eat special feed.

Important! Broilers are not raised for longer than 70 days. This age is characterized by a slowdown in growth, which means that the food will not pay for itself

The diet of small chickens includes millet, semolina, boiled eggs, barley and oats. In this case, the majority should be grain. 3-day-old young animals can be fed chopped greens, grain and eggs 8 times a day. From day 20 you can add boiled potatoes, bone meal and chalk, frequency - 4 times a day. You can purchase vitamins in specialized stores. After a month it is enough to give solid food

It is important that chicks always have clean, warm water to drink. In the second month, protein is removed from the diet, and the amount of grass increases

To prevent digestive problems, chickens should be given a solution of potassium permanganate. Fine gravel will also help.
