ABOUT BALANCE OF NUTRIENTS IN PREGNANT EWES ACCORDING TO DIFFERENT LEVELS OF ENERGY AND PROTEIN IN RATION

A.S. Tenlibaeva1, D.P. Badmaev2

During the studying of ration nutrients digestibility with different levels of metabolizable energy (ME) and crude protein (CP) in ewes of the Gissar breed at the different periods of pregnancy the authors showed that this parameter varies substantially according to ration composition and period of pregnancy. Therefore, the differencing of ME and CP consumption on pregnancy periods generates the most favorable conditions for digestibility of feed nutrients and enhancement of metabolism.

Keywords: pregnant sheep, nutrition needs, different levels of energy and protein, coefficient of digestibility, nutrients.
