УРОВНИ ПРОТЕИНА, АМИНОКИСЛОТ И ИХ СООТНОШЕНИЯ ДЛЯ ПОВЫШЕНИЯ ПРОДУКТИВНОСТИ СВИНЕЙ МЯСНОГО ТИПА

Abstract

The article presents the results of research when using complete compound feeds with different levels of protein, amino acids and their ratio in the diet of meat-type pigs, which allow to obtain average daily gains during the growing period 442–450 g with feed consumption per unit of increase 3.14–3.19 kg, crude protein – 531–560 g and metabolic energy – 42.7–43.6 MJ accordingly. Compound feeds with low protein levels with the addition of amino acids can reduce the excretion of nitrogen in feces and urine.
