Characteristics of the fatty acid composition of cow's milk when including in their diet activated and enriched silicon-containing additives

Relevance . Currently improving of the quality agricultural products is a point constant attention. The nutritional value and commercial milk depend on its chemical composition properties, which are influenced by numerous factors, most important among them animal feeding. prospects using feed additives based natural agro-minerals in husbandry increasing. These include such silicon-containing sorbents as zeolite, diatomite, bentonite, tripoli, montmorillonite. Material methods Production tests lasting 100 days were carried out OOO "Agrofirma "Tetyushskoe"" Ulyanovsk region. object study was Black-and-White cows. We created 4 groups principle analogy, each with 50 feeding household rations. difference follows: 1st group received only ration (OR); 2nd OR an additive modified zeolite enriched amino acid complex plant origin (the drug «Aminobiol»); 3rd diatomite same acids. Cows 4th without Results Feeding acids has positive effect fatty cow's milk, increases concentration caprinic (C10:0), lauric (C12:0), myristinic (C14:0), palmitic (C16:0) heptadecoic (C17:0) acids, productivity improves qualitative milk.
