New feed additives generation in dairy cattle breeding

Abstract

Relevance. Modern livestock breeders face an important task of producing organic products, in Russia this is regulated by the Federal Law “On Organic Products” (from 01.01.2020), it allows producers to enter in the state register and mark the products with the “organic” sign. There is a problem of deterioration of the quality of milk, low content of fat, protein, SOMO, deficiency of macro-and microelements, vitamins, which is associated with a violation of the proper feeding of animals. The use of innovative technologies for the activation and modification of silicon-containing minerals (diatomite and zeolite clinoptilolite) enhances their properties. This makes it possible to use them as an adsorbent, an ion exchanger and a source of readily available silicon and other mineral elements to produce high-quality organic products.Methods. To achieve this goal, in the Ulyanovsk region we organized a production experience in the conditions of a dairy farm of “Agrofirma Tetyushskoe” for a duration of 100 days. Three groups of 50 cows were formed: 1st — control, received only the basic diet (ОR), 2nd — experimental (ОR+ supplement based on modified zeolite enriched with amino acids), 3rd — experimental (ОR+ supplement based on modified diatomite enriched with amino acids). The supplement was given once a day, in the morning in a mixture with mixed feed, the input rate was 250 g/head/day. For the physiological experiment, 5 analog cows were selected in a group. To enrich the minerals, a complex of plant-derived amino acids of high purity and biological activity was used.Results The intake of additives based on silicon-containing natural minerals (zeolite and diatomite), processed with innovative technologies and enriched with plant-based amino acids, increases the level of animal productivity and ensures the yield of organic products high-quality. It has a prolonging effect.
