It is useful to give meat and bone meal to layers to increase egg production . For 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 making 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, thanks to its composition.
The composition of flour includes:
- Proteins. The amount of protein depends on the class of flour. The largest content in a first class product. The second and third grade contain more bones, so they have less protein.
- Fats. In the meat and bone powder of the first class, the lowest concentration of fat. Bone meal contains about 10%.
- Cellulose. All product classes contain the same amount of pulp. This component is absent in bone meal.
- Ash.The first class powder has the lowest ash content.
- The mineral component is phosphorus and calcium.
The composition of the food additive is established by the state standard. The GOST number must be indicated on the packaging of high-quality flour.
Protein is necessary for all living organisms to build the skeleton, muscles, and internal organs. A moderate amount of protein supplement must be added to the feed of laying hens, roosters, broiler chickens.
of hens and roosters are fed with dry feeds and mash from 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 food.
In the summer, hens walk, peck worms and insects. They get some protein from living food. The need for layers of protein and calcium is increased in the summer, so you still need to add meat or bone meal to the feed.
the normal dosage of flour for chickens should be no more than 6-7% of the total weight of the daily feed. According to the instructions, an adult laying hen should receive about 7-11 g of supplements per day.
There is a special instruction for the use of supplements for broiler feeding. Flour is introduced into the diet of young animals gradually, the dose is constantly increasing.How much powder to give 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.
Exceed the dosage of meat and bone and bone powder for young animals and adult chickens are not allowed. 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 provoke obesity or disease in chickens .
Meat and bone meal should have a brown or light brown color and a specific smell.
A poor quality product is easy to distinguish by signs:
- greenish tint ;
- putrid odor;
- musty smell.
A good product should have a uniform consistency. The mass should not be large lumps. This is a sign of violation of production technology and storage rules.
Putrid odor 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 there are more cases of biting and cannibalism .
It’s best to buy the mixture from the same trusted producer.
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 accumulate 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.
Basic steps and manufacturing principles
This mixture can be prepared at home, but This is a very laborious 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 like this:
- Carcasses of dead animals are cut.The meat is steamed, then cooled.
- The prepared meat and bones are crushed in a special grinding machine.
- The crushed product is sieved to separate large residues.
- The powder is poured into magnetic separator for cleaning small metal impurities.
- The mixture is treated with an antioxidant to prevent damage to 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, valuable food additives were supplied to stores.
For the manufacture of such a mixture, 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 the chicken and protein and calcium feeds, which helps to increase egg 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. Excessive daily dose will lead to the development of gout and obesity.
