Effect Analysis of Nutritional Regulation and Breeding Mode Optimization on Tibetan Sheep
摘要
Abstract
To address the problems of low production efficiency,indistinct breed characteristics,and acute forage-livestock conflicts in Tibetan sheep farming in the alpine pastoral areas of Gannan Prefecture,this study took Tibetan sheep as the re-search object and conducted experiments on nutritional regulation and breeding mode optimization in combination with the eco-logical characteristics of the alpine pastoral regions.It systematically analyzed the effects of optimized measures on the growth performance,reproductive performance and ecological adaptability of Tibetan sheep,and established a high-efficiency breeding technical system suitable for Tibetan sheep in the alpine pastoral areas of Gannan.A grouped comparative design was adopted,with a control group(traditional feeding+conventional breeding)and an experimental group(optimized nutritional regulation+molecular marker-assisted breeding).A 12-month feeding trial and reproductive monitoring were carried out,and the optimiza-tion effects were comprehensively evaluated in combination with practical production data.The results showed that compared with the control group,the average daily gain of Tibetan sheep in the experimental group was significantly increased(P<0.05),the lambing rate of ewes rose to 80.5%,and the milk yield was increased by 15%.Meanwhile,the daily grazing time of Tibetan sheep in the experimental group during the hay peri-od was shortened by 2 hours on average,the livestock carry-ing pressure on natural grasslands was reduced by 20%,and the ecological adaptability was significantly better than that of the control group.This study demonstrates that optimi-zing the nutritional regulation scheme and breeding mode of Tibetan sheep can effectively improve the growth and repro-ductive performance of Tibetan sheep,and alleviate the for-age-livestock conflict.It provides a theoretical basis and tech-nical support for the quality improvement,efficiency en-hancement and green sustainable development of the Tibetan sheep industry in alpine pastoral areas.关键词
