摘要
[目的]为了研究德国弗莱维赫(Fleckvieh)牛与本地母牛杂交F_(1)代育成母牛生长发育性状和生长发育规律,为培育北大荒乳肉兼用牛品种,开展选育提高奠定基础。[方法]采用各批次测定体重校正到统一月龄,测定了其初生、4月龄(断奶)、12月龄及18月龄4个阶段的体重、体尺,并对各阶段表型值比较分析。[结果]德国弗莱维赫(Fleckvieh)牛与本地母牛杂交F_(1)代母牛平均日增重、胸围和体斜长性状,在初生至4月龄断奶阶段生长发育最快;从4月龄断奶至18月龄,与纯种德国弗莱维赫种公牛与澳系(澳大利亚)西门塔尔母牛杂交后代相比,在体重和体尺上有一定差异。[结论]需要不断地改良,以提高后代的生长发育性状,进一步提高生产性能。
[Objective] The objective was to study the growth and development characters of F_(1) hybrid cows between German Fleckvieh cattle and Native cows, which would lay a foundation for the cultivation of dairy-meat cattle breed and the improvement in Great Northern Wilderness. [Method] The body weight and size data of F_(1) generation cows at newly-born stage, 4 months(weaning), 12 months and 18 months were compared and analyzed by using phenotypic values. [Result] The average daily gain, chest circumference and body length of F_(1) hybrid cows between German Fleckvieh cattle and Native cows grew the fastest from newborn to 4 months of age;From the age of 4 months weaning to 18 months, there were some differences in body weight and body size compared with the offspring of pure German Fleivich bulls and Australian Simmental cows. [Conclusion] Continuous improvement is needed to increase the growth and development characteristics of offspring and further improve production performance.
