Feeding soy shale is a valuable feeding stuff which contains proteins, carbohydrates, lipids. It is used during its direct addition to the animals’ ration, and it is also a valuable raw material in feed compounds industry. Soy shale can partially and sometimes completely replace fish flour and other expensive protein resources in the ration of fresh-water and sea fish because its amino acid composition completely matches the needs of many types of fish. Soy shale contains a wide variety of mineral substances, amino acids and proteins. It is used as the base for many feeding compounds. It is one of the most quality vegetable-based products for feeding farm livestock. Soy shale is digested well, and in its biological value it is close to animal-based proteins. It is recommended to introduce up to 35% of soy shale to the main ration of all types of livestock, poultry and fish. The application of soy shale in cattle breeding, poultry and fishing industry allows for significant savings in expensive feedstuff, at the same time it provides high energy feedstuff with a high content of vegetable-based protein for fish, poultry and animals. Soy shale is well digested and in its bioavailability it is as good as animal-based protein. Due to the above mentioned properties soy shale provides growth gain of young growth, increase of milk yield and significantly increases the quality of milk. Because it contains a number of amino acids such as lysine, threonine, tryptophane, isoleucine, soy shale strengthens immunity and, as a result, decreases morbidity and mortality of animals.
