Abstract

Abstract: Due to the seasonal variations of forage yield and nutritive value in desert grassland, the lack of nutrimental intake before mating period always leads to the poor fertility of ewes. To assess the short-term nutritional supplementary feeding on reproductive performance of freely grazed Gobi short-tailed ewes, an optimized dietary nutrition collocation scheme with high-nutrition feed were provided for the ewes 25 days before mating to improve the nutritional supplementation level in a short period of time. The results showed that the lambing rate of the ewes in the two experimental groups was 6.40% and 19.69% higher than that of the control group after short-term high-concentration supplementation, and the twin lambing rate was 6.92% and 10.20% higher than that of the control group. In this short-term nutritional supplementary feeding mode, the lambing performance of the ewes are improved to a certain extent, and the economic income of the herdsmen′s sheep raising is improved.

Key words: Gobi short-tailed ewes, supplementary feeding, twin lambs
