This study aims to improve the breeding conditions of Tibetan sheep in Mado County,located on the Qinghai-Tibet Plateau,by introducing standardized breeding management techniques to enhance production per-formance and breeding efficiency.The study employed a combination of grazing and supplemental feeding,compa-ring the outcomes with those of a natural grazing group.Results show that the standardized breeding group main-tained more stable body weights,with a weight reduction of 6.50%from December to the following March,com-pared to an 11.04%reduction in the natural grazing group.Additionally,the adult sheep mortality rate in the standardized group was 2.25%,significantly lower than the 4.27%observed in the natural grazing group.In terms of reproductive performance,the primiparous ewes had a reproduction rate of 91.67%,which was 24.18 percent-age points higher than the natural grazing group,and the multiparous ewes had a reproduction rate of 98.34%,5.07 percentage points higher than the natural grazing group.Overall,the standardized breeding approach im-proved the stability of sheep body weight,reduced mortality rates,and significantly enhanced reproductive perform-ance,providing scientific evidence and practical guidance for the sustainable development of local animal husbandry.
