摘　　要：为研究生态因子对中国地方绵羊品种生产性能的影响,采集了42个中国地方绵羊品种的生产性能指标及其所在地的生态因子数据,建立了中国地方绵羊品种生态因子对生产性能的回归方程。结果表明,年均日照时数是影响地方绵羊生产性能最主要的生态因子,年均降水量、无霜期和平均海拔对地方绵羊的生产性能有一定影响。年均日照时数极显著影响公母羊成年体重、成年体高、成年体长、成年胸围、宰前活重、胴体重、屠宰率、净肉率和初生羔重(P<0.01);年均降水量极显著影响公母羊成年体长、屠宰率、净肉率,母羊成年体高和成年胸围(P<0.01),显著影响公羊成年胸围和宰前活重(P<0.05);无霜期极显著影响公羊成年体高(P<0.01),显著影响公母羊成年胸围、公羊屠宰率和母羊成年体高(P<0.05);平均海拔显著影响公羊宰前活重和胴体重(P<0.05)。研究结果对于中国地方绵羊的遗传育种与开发利用具有一定参考价值。In order to study the influence of ecological factors on the production performance of Chinese local sheep breeds,the production performance indexes of 42 Chinese local sheep breeds and the ecological factor data of their places were collected,the regression equation of ecological factors of Chinese local sheep breeds on production performance was then established.The results of regression analysis show that the average annual sunshine hours are the most important ecological factors affecting the production performance of local sheep,and the average annual precipitation,frost-free period and average altitude have certain effects on the production performance of local sheep.The details are as follows:The average annual sunshine hours significantly affect the adult weight,adult height,adult length,adult bust,live weight before slaughter,carcass weight,slaughter rate,clean meat rate and newborn lamb weight(P<0.01);The average annual precipitation significantly affected the adult body length,slaughter rate,net meat rate,adult body height and adult chest circumference of ewes(P<0.01),and significantly affected the adult chest circumference and live weight of rams before slaughter(P<0.05).The frost-free period significantly affected the adult body height of ram(P<0.01),the adult bust of ram,the slaughter rate of ram and the adult body height of ewe(P<0.05).The average altitude significantly affected the live weight and carcass weight of ram before slaughter(P<0.05).The average annual precipitation significantly affects the adult height and birth weight of rams(P<0.05).Frost-free period has no significant influence on other production performance indexes except the adult length of ewe(P<0.05).The results have certain reference value for the genetic breeding,development and utilization of local sheep in China.
