发布时间:2019-06-12 18:06
【摘要】:【目的】羔羊前60 d生长发育较快,研究0~60日龄新吉细毛羊生长发育规律,为生产中早期饲养提供理论依据。【方法】测定新疆塔城种羊场613只新吉细毛羊羔羊初生、10、20、30、40、50和60日龄的体重,分析不同日龄段羔羊的生长发育规律及不同群别对羔羊生长的影响。【结果】新吉细毛羔羊的日增重和相对生长速度0~10日龄最快,20~50日龄下降,50~60日龄大幅下降,可将新吉细毛羔羊的生长分为3个阶段,分别为0~10日、20~50日龄及50~60日龄。【结论】0~10日龄,羔羊生长发育很快,必须让羔羊吃上初乳以及应加强母羊的哺乳。20~50日龄是新吉细毛羔羊生长发育较快的时期,应对羔羊加强饲养管理和满足其营养供给。饲养管理较好的羊群羔羊生长快,日增重高。
[Abstract]:[objective] to study the growth and development of Xinji fine wool sheep aged 0 ~ 60 days in the first 60 days, and to provide theoretical basis for early breeding in production. [methods] the birth weight of 613 Xinji fine wool lambs at Tacheng breeding farm in Xinjiang was measured, 10, 20, 30, 40, 50 and 60 days old, respectively. The growth and development of lambs at different ages and the effects of different populations on the growth of lambs were analyzed. [results] the daily gain and relative growth rate of Xinji fine wool lambs were the fastest, 20 鈮,
