An experiment was made to compare some basic productive indexes in sheep of the Pach-head Maritsa breed when replacing barley grain with sunflower expeller in their rations during “flushing – pregnancy”- period.
The obtained results indicate a trend of positive influence of feed replacement as follows: body scoring index of sheep at the end of pregnancy - 3.58 (expeller) against 3.25 (barley); percentage of ewes with twins – 28.57 vs. 20%, respectively; average live weight of lambs at birth – 4,110 vs. 3,974 kg; average live weight of lambs at 30 days – 15,060 vs. 14,720 kg.
With identical prices for both forages, the authors recommend replacing barley with sunflower expeller.
