Feed yeast for cattle: instructions for use and chemical composition

The use of fodder yeast in cattle breeding is an important point for farmers who want to fully feed their livestock, maintain their he alth and reduce the cost of maintenance. Yeast is not an independent type of food, they are added to the usual compound feed to accelerate weight gain, increase milk yield, meat productivity of cattle. When choosing, using and storing an additive, it is important to follow the instructions given by the manufacturer.

How fodder yeast is made

Fodder yeast is a fungus that has only a positive effect on the organisms of animals and humans, due to which they are used in various spheres of life.Feed products used for feeding cows are brown granules or powder mixture with a pronounced yeast aroma. The biomaterial is produced in specialized workshops, where optimal temperature and humidity are maintained.

Crops are grown in conditions of maximum nutrient medium enriched with oxygen. GOST 20083-74 is observed during production, the finished additive is dried, packaged, then packaged and sent to points of sale.

Product composition

Yeast product made from leftover organic derivatives:

skins of sunflower seeds;
straw, reeds;
corn on the cob;
waste left over from wood production.

The highest quality additives are those made with the addition of distillery stillage. The composition of feed for cattle includes a small amount of protein compounds, so fodder yeast is recommended to be used in livestock nutrition to compensate for the deficiency of minerals and organic substances.

The chemical composition of the product includes:

protein - 31-37%;
protein - 37-52%;
fiber - 1.3-2.8%;
fats - 1.8%;
dietary fiber - 1.8%;
wood ash - 10%.

The product contains vitamins B, E, D, K, which support a full digestive function, and substances necessary for the absorption and high absorption of vitamins, trace elements, proteins, carbohydrates.

Benefits and harms

It has been established that the norm for cattle is the consumption of 110 grams of protein per unit of feed, and when feeding livestock with conventional compound feed, only 85 grams of protein is present on the menu.This leads to poor assimilation and digestion of food, reduced productivity, weight gain and the volume of milk produced.

Benefits of feed yeast in barns:

acceleration of young weight gain;
increase in cattle performance - milk yield, increase in slaughter weight;
normalization of digestion processes;
positive effect on the composition of gastric and intestinal microflora;
improving semen quality in sires;
strengthening livestock immunity and preventing infectious diseases;
increasing the nutritional value of food;
reducing feed consumption, which has a positive effect on the cost of raising cattle.

Protein and protein are vital for cows, but it is difficult to get enough of them only on plant foods.

Such amino acids as tryptophan, methionine, lysine contained in yeast are not produced by the animal's body, but their deficiency negatively affects all vital processes.

There are no drawbacks to additives. But if a farmer consistently exceeds the manufacturer's recommended dosage or uses poor quality products, cows can develop obesity or digestive dysfunction.

Feed yeast varieties

Products can be divided into three groups, according to the way they are produced:

Hydrolysis - used in the production of waste from food and wood. Under intense acid and temperature influence, mushrooms multiply in the raw material.A ton of hydrolytic yeast contains from 240 to 450 kilograms of protein. The product has a yellowish or brownish tint and is available in granular or powder form.
Classic - are considered the most useful for animals, since they include a large mass of proteins (about 400 kilograms per ton) and a minimum amount of crude protein. They are produced using stillage. The product is in the form of a flake powder, also available in granular form.
Protein-vitamin concentrated (BVK) - fungal colonies are grown on waste left after the processing of petroleum products, on organic alcohol and natural gases. BVK include the maximum amount of protein (up to 800 kilograms per ton) and vitamin B.

During the manufacture, many manufacturers subject the finished product to ultraviolet treatment. This increases the concentration of vitamin D in it, and the natural value of vitamin B comes to naught. Farmers need to consider this fact when buying a product.

Cow Application

It is important for animals to get the required daily dose of protein, which is why a yeast feed product should be included in the menu:

cows with high milk yields (more than 20 liters) during lactation and milking. The protein contained in the supplement contributes to the normalization of microflora indicators in the rumen and the stabilization of its functions, the prevention of acidosis, and the maintenance of stable lactation. Daily portion - 500-800 grams;
cows consuming sour silage, fresh and sour pulp - to preserve the digestive function, protect it from the pathological effects of acid, improve intrauterine formation of calves, increase milk yield. One cow can be given from 500 grams to 1 kilogram of supplement per day;
dairy cows fed chaff - to maintain optimal acidity, improve food digestion and absorption of nutrients. The daily dose of the supplement for a cow is 1 kilogram;
producer bulls - start giving the product 2-3 weeks before covering cows or collecting material for fertilization, 0.5-0.8 kilograms per day and feed them until the end of the mating period;
young animals - with malnutrition or feeding with low-quality hay. Calves are given 0.2-0.3 kilograms of yeast per day, as the calves grow up, the dosage increases.

According to the instructions, yeast must be added to the main grain and combined mixtures.

When stirring, if a little more yeast was added than expected, nothing terrible will happen, since their use does not harm animals.

How to choose and store

Good yeast should have a pleasant yellowish-brownish hue, a pronounced yeasty aroma, and be dried. Elements of rot or mold are not allowed.

Yeast storage conditions:

temperature - from -30 ^оС to +30 ^оС;
dark room, no moisture;
away from chemical compounds, poisons, because the yeast is able to absorb pathological evaporation.

If the farmer suspects that the yeast is expired, has rotted, or has noticed moldy inclusions in the bags, it is better not to purchase such a product. It will not benefit livestock, but it can provoke the development of serious diseases of the gastrointestinal tract.

The shelf life of fodder yeast is 6 months, after which it is not recommended to give it to cows. Fodder yeast has long won the trust of farmers by increasing livestock productivity and milk yield, improving the quality of meat and milk, and maintaining animal he alth at the proper level. The use of the product in animal husbandry also helps to save finances and increase the profitability of the farm.
