SOYA

Soya is the most valuable protein feed. It contains 32-45% protein, up to 20% fat and relatively few carbohydrates. Soy protein is characterized by high solubility (the sum of salt- and water-soluble protein fractions exceeds 80%) and a very satisfactory amino acid composition - 1 kilogram of soy contains lysine - 21.9 grams, tryptophan - 1.3, methionine - 4.6, cestine - 5 .3 grams. Like other legumes, soy is rich in phosphorus (6.9 grams per kilogram). In terms of content, biological value and protein yield per unit area, no culture can compare with soybeans.

At the same time, due to the presence of a large amount of anti-nutritional substances (trypsin inhibitor, solanine, hemagglutinin, urease, lipoxidase, etc.), it is practically impossible to feed soybeans to animals without pre-treatment. Pigs, when 15% soybeans are included in the feed, refuse to eat feed; in calves, it causes diarrhea. All soybean antinutrients are thermolabile and completely inactivated when heated. This also reduces the solubility of the protein, which significantly increases the value of this feed for ruminants. Before feeding, the grain must be processed in high-temperature dryers at an exhaust gas temperature of 105 degrees Celsius. It is most expedient to use processed soybean for the preparation of feed for lactating cows and laying hens, including it in an amount of 15-20%.

The enterprise processes soybeans in accordance with GOST 17109-88 "Soybeans. Requirements for procurement and supply"
