摘　　要：为了研究长江三角洲白山羊不同杂交组合生长发育的差异,以长江三角洲白山羊为母本、以萨能奶山羊和波尔山羊为父本进行杂交选育,分析萨白F_(1)、波萨白F_(2)和长江三角洲白山羊F_(0)60日龄体重与体尺指标的变化。结果显示:波萨白F_(2)各日龄体重、平均日增重均显著高于长江三角洲白山羊F_(0)(P<0.05);波萨白F_(2)各日龄体重和平均日增重均高于萨白F_(1),萨白F_(1)各日龄体重和平均日增重均高于长江三角洲白山羊F_(0),但差异均不显著(P>0.05)。整个试验期间,波萨白F_(2)、萨白F_(1)各日龄体尺指标均高于长江三角洲白山羊F_(0),但差异均不显著(P>0.05);各组羊的体尺数据随着日龄的增加呈递增的趋势。该试验通过分析不同杂交组合羔羊体重、体尺等早期生长发育性状,为培育具有较高经济价值的长江三角洲白山羊肉用品种(系)提供了一定参考。In order to investigate the differences in the growth and development among different hybrid combinations of Yangtze River Delta white goats(YDW),cross breeding was conducted using Yangtze River Delta white goats as the female parent,with Saanen Dairy Goat(SN)and Boer Goat(BR)as the male parent.The changes of body weight and body size indices of SN×YDW(F_(1)),BR×SN×YDW(F_(2)),and YDW(F_(0))within 60 days were analyzed.The results showed that the body weight at different day-ages and average daily gain of BR×SN×YDW(F_(2))were significantly higher than YDW F_(0).The body weight at different day-ages and average daily gain of BR×SN×YDW(F_(2))was higher than that of SN×YDW(F_(1)),the body weight at different day-ages and average daily gain of SN×YDW(F_(1))was higher than that of YDW(F_(0)),but there was no significant difference(P>0.05).During the whole experimental period,the body size indices of BR×SN×YDW(F_(2))and SN×YDW(F_(1))were higher than YDW(F_(0))at different day-ages,but the differences were not significant(P>0.05).The body size of the goats in each group increased with the day-age.This study analyzed the early growth and development traits of different hybrid combinations of goat breeds,which provided certain references for cultivating Yangtze River Delta white goat meat varieties(lines)with high economic values.
