EXTRUDED LUPIN IN YOUNG CATTLE FEEDING
Researches were carried out to study the efficiency of extruded lupine in compound feed on performance of young cattle aged 3 to 6 months. It was determined that feeding young cattle with extruded lupine added to the compound feed in the amount of 10% had a positive effect on physiological state of the animals, as evidenced by increase in the total protein level in blood by 8.9%, glucose by 8.5%, and decrease in the urea level - by 8.5%. Decrease in the urea level in blood of animals indicates the decrease in the amount of ammonia due to decrease of protein decomposition intensity, which is associated with normalization of protein metabolism in the body and better conditions of ruminal digestion. Compound feeds used with extruded lupine also contribute to increase in average daily weight gain by 6.4%, decrease in feed costs for weight gain by 4.9%, and a cost price of weight gain by 4.78%.
