Effect of Dietary Omega-3 Poli Unsaturated Fatty Acids During the Flushing Period on Reproductive Performance of Karayaka Ewes

摘要

This experiment was conducted to investigate the effects of supplemented omega 3 poly unsaturated fatty acids on fertility of Karayaka sheep during the flushing period. This trial was arranged on 3-4 year old, average 55 +/- 0.5 kg live weight, 80 head Karayaka sheep were distributed completely Randomize into 4 groups. Oestrus synchronization was performed in the three groups of sheep except for control group. Experimental groups were pasture, pasture (oestrus synchronization), barley and Omega-3. Progeny yields were determined as 80% in the control, 125% in the pasture, 116% in the barley and 135% in the omega-3 groups.The highest twin birth was observed in omega 3 group (44%), follwed by pasture group (33%) and barley group (24%). The results indicated that, addition of omega-3 polyunsaturated fatty acids to supplemental feeds increased fertility of Karayaka sheep.
