How to calculate the dose of bone and meat and bone meal for chickens

Meat and bone meal are valuable protein supplements for pet and poultry feed. The product is prepared from the carcasses of dead animals that are not suitable for human consumption. Meat and bone meal for chickens is completely safe, but it is important to observe the dosage.

Bone and meat and bone meal for chickens

It is useful to give meat and bone meal to laying hens to increase egg production. For the healthy growth of broiler chickens, a lot of protein is also needed, therefore meat and bone and bone meal is used as an additive for broiler fattening.


For the manufacture of flour, meat and bones of cattle that have fallen from disease or old age are used. This meat is not suitable for human nutrition; processed products are added to animal feed. Carcasses are processed, cleaned and ground. Meat and bone powder is useful for cattle, pigs and poultry due to its composition.

The composition of flour includes:

  • Squirrels. The amount of protein depends on the class of flour. The largest content in a first class product. The second and third classes contain more bones, so there is less protein in them.
  • Fats. In the meat and bone powder of the first class, the lowest concentration of fat. Bone meal contains about 10% of it.
  • Cellulose. All product classes contain the same amount of pulp. This component is absent in bone meal.
  • Ash. The first grade powder has the lowest ash content.
  • The mineral component is phosphorus and calcium.

The composition of the food additive is established by state standard. On the packaging of high-quality flour must be indicated by GOST.

Protein is necessary for all living organisms to build the skeleton, muscles, internal organs. In the feed of laying hens, roosters, broiler chickens, it is necessary to add a moderate amount of protein supplement.


chickens and roosters are fed with dry feed and mash of vegetables, cereals, meal, etc. The basis of the diet of chickens is wet mash. Meat and bone meal can be added to both types of feed.

In summer, chickens walk, peck worms and insects. They get some protein from living food. The need for layers of proteins and calcium is increased in the summer, so you still need to add meat and bone or bone meal to the feed.

Meat and bone meal should be added to the feed.

the normal dosage of flour for chickens should be no more than 6-7% of the total mass of daily feed. According to the instructions, an adult laying hen should receive about 7-11 g of supplements per day.

For broiler feeding, there is a special instruction on the use of additives. Flour is introduced into the diet of young animals gradually, the dose is constantly increasing. How much to give powder to chickens:

  • 1-5 days - the product is not added to the feed.
  • 6-10 days - the norm is 0.5-1 g per head.
  • 11-20 days - the norm is 1.5-2 g per head.
  • 21-30 days - the norm is 2.5-3 g per head.
  • 31-63 days - daily dose - 4-5 g per head.

The gradual use of protein supplements will ensure healthy growth and weight gain.

It is impossible to exceed the dosage of meat and bone and bone powder for young and adult chickens. This can lead to the development of gout and impaired protein metabolism.


Feeding chickens and chickens should be done only with high-quality bone meal. Do not give your birds cheap supplements. Poor quality powder can trigger obesity or disease in chickens.

Meat and bone meal should have a brown or light brown color and a specific smell.

The quality of meat and bone meal

Poor quality product is easy to distinguish by signs:

  • greenish tint;
  • yellow;
  • putrefactive odor;
  • musty smell.

A good product should have a uniform consistency. The mass should not be large lumps. This is a sign of a violation of production technology and storage rules.

Putrid smell indicates poor processing of meat carcasses. A musty smell is about improper storage of the product. A color other than brown may indicate impurities of soy. Soy in flour is added by unscrupulous manufacturers to reduce the cost. Chickens get less protein; in a flock, cases of biting and cannibalism increase.

It is best to buy the mixture from the same trusted manufacturer.

How to store

The correct content of feed allows you to maintain their quality and useful properties for a long time. Bone meal should not gain excess moisture and cake.

Meat and bone powder is stored in its original packaging. The room should be clean, dry and well ventilated. The room should also be cool.

The average shelf life is about 6 months. The protein gradually decomposes, ammonia accumulates in the product. Favorable conditions for the decomposition of protein are created at elevated temperatures. High humidity creates conditions for the development of bacteria and microscopic fungi, so you can’t feed the chickens with an expired mixture.

The main stages and principles of manufacturing

This mixture can be prepared at home, but it is a very time-consuming process. You need a special grinder that works on the principle of a coffee grinder of large size and power. It is much easier to buy a finished product, especially for a large farm.

At enterprises, bone meal is made as follows:

  • Carcasses of dead animals are being carved. The meat is steamed, then cooled.
  • Prepared meat and bones are crushed in a special crushing machine.
  • The crushed product is sieved to separate large residues.
  • The powder is poured into a magnetic separator to remove fine metal impurities.
  • The mixture is treated with an antioxidant to prevent spoilage of fat components.

Then the mixture is Packed in bags of different volumes and sent to warehouses. If only animal raw materials were used, production technologies were followed, and a valuable food supplement was delivered to stores.

For the manufacture of such mixtures, the remains of meat production are also used. This is a different kind of trim, their use does not have commercial benefits. The quality of such flour, subject to all the rules, remains high.

Meat and bone meal enriches chicken feed with protein and calcium. This helps to increase egg laying in laying hens. Broilers using this mixture gain weight faster. The nutritional value of the product is very high, therefore, the dosage must be strictly observed. Exceeding the daily dose will lead to the development of gout and obesity.
