Abstract

The aim of the present study is to compare the effect of including in rations sunflower meal, dry disstiler’s grain and alfalfa silage as protein sources when feeding breeding lambs after 25 kg live weight. 30 male and female lambs from the Pleven blackface sheep breed were used. The intake of concentrated feed from one animal is highest in lambs fed alfalfa silage (0,866 kg DM / day).The lowest cost for KER is observed for lambs fed on a dry disstiler’s growth based ration. The average daily growth on the 14th day is the highest, in the group fed with a ration based on dry disstiler’s grain - 294g. While on the 28th day, the average daily gain was highest in the group of lambs fed silage (296g), and on the 42nd day the same group maintained its highest growth (292g) compared to the other two groups. The lambs fed with three rations based on three protein sources (alfalfa silage, sunflower meal and dry disstiler’s grain) achieved an average daily growth of up to 0,291 g, and the differences in growth between the three groups of lambs were insignificant.
