USE OF NUTRIENTS AND ENERGY OF DIETS SIMMENTALSKAYAS BULL-CALVES OF BREED WHEN FEEDING FORAGES FROM VARIOUS BEAN CULTURES

Yaushev R.R
Nutrients of the consumed forages are used in an organism for construction new and renewal of worn-out fabrics, and also are a power source, necessary for departure of physiological functions and replenishment of the substances spent in the course of activity. The best indicators of digestibility of nutrients, bull-calves of the I group who consumed сенаж the kozlyatnikovy possessed. They surpassed contemporaries from other groups on digestibility of solid II group – for 0,5%; III – 1,1; The IV group – 2,1%; the organic – for 0,3%; 0,4; 1,1%; protein – for 0,4%; 1,8; 2,0%; crude fat – for 0,2%; 0,2 and 0,7%; celluloses – on 0,7; 0,9 and 1,9%; BEV – for 0,1%; 0,3 and 2,3% respectively. Inclusion in a diet of animals сенажа from bean cultures in comparison with hay, I allowed to increase efficiency of gross energy for 0,88-1,67%, exchange – for 1,10-1,81%. And, higher rates were noted when feeding to bull-calves сенажа from a kozlyatnik east. Higher adjournment of nitrogen in an organism at the bull-calves consuming сенаж from a kozlyatnik in comparison with contemporaries, eating other types of a forage from the bean was respectively 4,2% higher (Р <0,05), 10,5% and 23,3% (Р<0,05). Thus, the diet of feeding of an animal influences digestibility of nutrients, nature of use of energy, nitrogenous part of diets. Use them better and more the bull-calves consuming сенаж and hay from a kozlyatnik, than from a lucerne acquire in an organism.
