Abstract The data pertaining to 6874 lambs born to a total of 145 sires spanning over a period of 49 years (1969–2017) were collected from Mountain Sheep and Goat Research Station, SKUAST-K, Shuhama, Kashmir for a comprehensive evaluation of the growth performance of Corriedale sheep under Indian (temperate) conditions to assess the random effect of sire and fixed effects of period, sex, and type of birth on its performance. All the 145 sires, during the study period, were selected from within the farm. Evaluation was done for 11 performance traits viz: birth weight (BW), weaning weight (WW), six months body weight (SMW), nine months body weight (NMW), yearling body weight (YBW), average daily gain from birth to weaning (ADG-1), metabolic mass at weaning (WW0.75), Kleiber ratio from birth to weaning (KR-1), average daily gain from weaning to yearling age (ADG-2), and metabolic mass at yearling age (YBW0.75) and Kleiber ratio from weaning to yearling age (KR-2). The overall least-squares means for BW, WW, SMW, NMW, YBW, ADG-1, WW0.75, KR-1, ADG-2, YBW0.75 and KR-2 were 3.66 ± 0.02 kg, 13.48 ± 0.14 kg, 18.79 ± 0.25 kg, 21.96 ± 0.19 kg, 25.23 ± 0.19 kg, 109.0.21 ± 1.56 gm/day, 7.01 ± 0.06 kg, 15.29 ± 0.10, 41.49 ± 0.42 gm/day, 11.23 ± 0.07 kg and 3.64 ± 0.29, respectively. The effect of sire and period was significant (p

印度 J&K 的 Corriedale 绵羊生长性能的遗传评估

摘要 从克什米尔舒哈马市 SKUAST-K 山绵羊和山羊研究站收集了 49 年（1969-2017 年）共 145 只公牛出生的 6874 只羔羊的数据，以对生长进行综合评估。 Corriedale 绵羊在印度（温带）条件下的表现，以评估父亲的随机影响和时期、性别和出生类型对其表现的固定影响。在研究期间，所有 145 头公牛都是从农场中挑选出来的。评估了 11 个性能特征，即：出生体重 (BW)、断奶体重 (WW)、六个月体重 (SMW)、九个月体重 (NMW)、一岁体重 (YBW)、从出生到出生的平均日增重断奶 (ADG-1)，断奶时的代谢质量 (WW0.75)，从出生到断奶的克莱伯比率 (KR-1)，从断奶到周岁的平均日增重 (ADG-2)、周龄的代谢质量 (YBW0.75) 和从断奶到周岁的 Kleiber 比 (KR-2)。BW、WW、SMW、NMW、YBW、ADG-1、WW0.75、KR-1、ADG-2、YBW0.75 和 KR-2 的总体最小二乘均值为 3.66 ± 0.02 kg、13.48 ± 0.14 kg , 18.79 ± 0.25 kg, 21.96 ± 0.19 kg, 25.23 ± 0.19 kg, 109.0.21 ± 1.56 gm/day, 7.01 ± 0.06 kg, 15.29 ± 0.10, ± 0.19 kg, ± 1.56 gm/day, 15.29 ± 0.10, ± 0.19 kg ± .3.0 .7 .0 .0 .0 .00分别。父系和时期的影响显着（p 分别为 01 ± 0.06 kg、15.29 ± 0.10、41.49 ± 0.42 gm/天、11.23 ± 0.07 kg 和 3.64 ± 0.29。父系和时期的影响显着（p 分别为 01 ± 0.06 kg、15.29 ± 0.10、41.49 ± 0.42 gm/天、11.23 ± 0.07 kg 和 3.64 ± 0.29。父系和时期的影响显着（p
