摘　　要：[目的]研究旨在探究中国肉用西门塔尔牛和德系乳肉兼用西门塔尔牛与河北省本地西杂牛杂交的改良效果,为河北省培育优质肉牛提供参考。[方法]本研究采用中国肉用西门塔尔牛冻精与德系乳肉兼用西门塔尔牛冻精与河北省本地西杂母牛进行杂交,测定其后代的生长发育指标,对两种杂交后代的生长发育性状进行比较分析。[结果]中国西门塔尔牛杂交后代的初生、3月龄、6月龄及12月龄体重均大于德系西门塔尔牛杂交后代,但结果差异不显著;日增重随着月龄增加而逐渐下降,其中除4~6月龄时德系西门塔尔牛杂交后代母牛日增重大于中国西门塔尔牛杂交后代母牛外,其余时期中国西门塔尔牛杂交后代的日增重均大于德系西门塔尔牛杂交后代;中国西门塔尔牛杂交后代胸围和腹围大于德系西门塔尔牛杂交后代,体高、十字部高及体斜长小于德系西门塔尔牛杂交后代。[结论]本研究中肉用型杂交后代较乳肉兼用型杂交后代具有更好的生长发育性能,但差异不显著。[Objective]This study aimed to investigate the effect of crossbred cows between Chinese Simmental beef cattle,dairy-meat dual purpose Simmental and Hebei local hybridized,and to provide reference for breeding quality beef cattle in Hebei province.[Method]In this study,the frozen semen of Chinese Simmental beef cattle and German Simmental were crossed with local Simmental crossbred cattle in Hebei Province to determine and compare the growth and development indexes of their offspring.[Result]The weight of 0,3,6,12 months old of Chinese Simmental hybrid offspring were all higher than the German Simmental hybrid offspring,but the difference was not significant.The average daily weight gain(ADG)decreased with age.The ADG of Chinese Simmental hybrid offspring were greater than that of German Simmental,except the ADG of the heifers of German Simmental at 4 to 6 months were greater than the Chinese Simmental.The chest girth and abdomen circumference of beef Simmental hybrid offspring were larger than the German Simmental hybrid offspring,but the body height,hip cross height and body length were smaller than those of the German Simmental hybrid offspring.[Conclusion]In this study,the Chinese Simmental hybrid offspring had better growth and development performance than the German Simmental hybrid offspring,but the difference was not significant.
