The high quality of products with maximum productivity can be achieved in modern livestock production by using balanced fodder. The production of fodders containing a significant amount of protein is a priority task of modern agricultural enterprises since the lack of protein in the diet of animals affects the quality of products and reduces productivity. Dry brewers yeast is a unique product containing up to 50% of high-quality, high-grade, easily digestible protein, which includes 17 essential amino acids, most of which are indispensable. Its composition contains D, F, E, K vitamins, group B vitamins, biotin, minerals – magnesium, sodium, calcium, potassium, copper, zinc, manganese, iron, zinc, chromium, selenium, sulfur, phosphorus, various carbohydrates and fats, as well as RNA – ribonucleic acid, which prevents the destruction of cells and premature aging. Brewers yeast is used in the production of a wide range of animal fodders, food industry and pharmacology. The main characteristics of the composition of dry brewers yeast: - 30-40% of carbohydrates; - 40-47% of high-grade protein; - 1.5-2% of fats; - 10-13% of crude fiber. By biological value and the content of amino acids, they are much superior to plant foods. In the context of the concentration of lysine, when comparing the amino acid composition of the feed, they are inferior only to fishmeal. Table 1.

The most often it is used for feeding poultry and pigs, as it is a source of essential amino acids. Recommended standards for inclusion of dry brewers yeast in the diet: for cattle – 0.2-1.0 kg, for pigs – 0.03-0.6 kg, for poultry 1-20 g, for goats, sheep – 0.05-0.08 kg, per head per day. Our company uses equipment that allows for drying brewers yeast without losing the nutritional properties of the product. The priority of our company is the production of an ecological product that meets the international quality criteria.
