Kylymnyuk A. Digestibility and an exchange of nutrients at pigs brought up on diets balanced by quality of protein.

The stated experimental material gives the basis to approve, that animals who receive balanced under the contents of this amino acid feed and its joint additive with methionine, and glutamine acid, use nutrients of a feed in comparison with animals who received forages of the basic diet better. Efficiency of pigs is investigated at consumption various of additives of amino acids and an expense of nutrients for their growth. In identical conditions the charge of nutrients on 1 kg of a gain of weight is less on 15,6 % at pigs whom entered into a diet amino acid the additive lysine and glutamine acids, than at animals who received forages of the basic diet. Studying of internal bodies and parameters of products of slaughter of animals, has shown, that animals has shown, that animals who received the additive as lysine and glutamine acids, better grew and developed. So daily average additional weights of pigs which in structure of a diet received the additive lysine, were up to standard 781 g, lysine and glutamine acid 830 g, lysine and methionine 771 g and lysine, methionine and glutamine 800 g. Profitability of cultivation of pigs at use lysine exceeded profitability of pigs, what grow on the basic diets on 14,5 %, and at use of diets with use lysine and methionine - on 5,8 %.
