Зависимость рубцового пищеварения и продуктивности молодняка крупного рогатого скота от крупности помола зерна

Зависимость рубцового пищеварения и продуктивности молодняка крупного рогатого скота от крупности помола зерна

Abstract

Протеин молотого зерна пелюшки в течение 6 часов инкубации в рубце распадается на 65-76%, дробленого - на 19-39%. Использование в кормлении молодняка крупного рогатого скота дроблёного зерна пелюшки приводит к снижению содержания в рубцовой жидкости небелкового азота на 3,3-9,3 % и аммиака - на 3,3-17,2%, повышению концентрации белкового азота на 5,1-6,3%, рН - на 0,1-0,2, среднесуточных приростов живой массы - на 4,9 %, при снижении затрат кормов на получение продукции на 6,6% по сравнению с молотым. Protein of ground grain of field pea during 6 hours of incubation in the rumen degrades almost 65-76%, while this value for the crushed grain makes 19-39%. Crushed field pea grain in feeding young cattle leads to decrease in the content of non-protein nitrogen in the rumen fluid by 3.3–9.3% and ammonia - by 3.3-17.2%, and increase in concentration of protein nitrogen by 5.1- 6.3%, pH - 0.1-0.2, average daily weight gain - 4.9%, while reducing the feed cost for production by 6.6% compared to the ground grain.
