Abstract

Purpose. To investigate the chemical composition and nutritional value of loose and granular feed. To make samples of loose and granular feed, make chemical analysis of loose and granular feeds, compare their chemical composition and content of essential nutrients. Methods. In the process of research general scientific methods were used: deduction, scientific hypothesis and abstraction. Zootechnical analysis methods were used to determine the chemical composition of compound feeds. Results. Analysis of the chemical composition of loose and granular feed in absolutely dry matter shows a higher content of essential nutrients in granular feed, so the content of crude protein in granular feed is higher by 3.52%, crude fat – by 1.45%, crude fiber and nitrogen-free of extractives – by 1.48% and by 2.79% lower than in bulk feed. Nutritional value of one kilogram of granulated feed in absolutely dry matter is 0.04 energy feed units, or 0.37 MJ, higher than of bulk feed, and content of digestible protein by 18 g, or 14.5%, higher than in bulk compound feed. 136.8 g of crude protein and 107.8 g of digestible protein fall per one energy feed unit in loose feed, 161.8 g of crude protein and 119.3 g of digestible protein in granular feed, or 25g and 11.5 g more. Analysis of the carbohydrate-lignin composition of granular and loose feed in absolutely dry matter shows a decrease of 2.8% in the amount of easily soluble sugars, starch – by 1.41%, sugar – by 0.40%, hemicellulose – by 0.39%, lignin – by 0.82% in granular feed. Conclusions. The use of granulation allows to increase the energy and protein nutritional value of feed due to the concentration of essential nutrients in the dry matter of granulated feed.
