摘  要：
[目的]遏制宜昌白山羊生产性能的下降,改善宜昌白山羊的生长现状。[方法]以宜都市王家畈乡良种繁育场提供的选育后的宜昌白山羊为观测羊只,对初生、2月龄、6月龄及周岁公、母羊进行生长特性的观察及生长性能的测定。[结果]选育后的宜昌白山羊四肢健壮,背宽而后躯发达,肌肉丰满,合群性好,放牧采食性能好,适应当地气候和粗放的饲养管理条件。选育后的宜昌白山羊公、母羊平均初生重为1.86 kg,2月龄、6月龄、周岁羊平均体重分别为7.07、12.75、19.69 kg,分别比选育前提高11.87%、17.08%和23.29%。选育后的各阶段宜昌白山羊的体高、体长、胸围均高于选育前的同阶段宜昌白山羊。[结论]选育后的宜昌白山羊的生长性能得到提高,选育效果明显。

摘  要：
[Objective] The study was to prevent the decrease of performance of Yinchang white goat and improve its present situation of growth.[Method] With selected Yinchang white goats provided by improved variety breeding farm in Wangjiafan township in Yidu City as observed goats,the growth characteristics of ram and ewe with nascent,2 month old,6 month old and yearling were observed and their growth performance were determined.[Result] The selected Yinchang white goats had stuggy limbs,wide back,developed hindquarter,plump muscle,good gregariousness and good feed intake ability during grazing.And the goats adapt to local climate and extensive feeding and management condition.The average birth weight of selected ram and ewe of Yinchang white goat was 1.86 kg,and the average weight of goats with 2 month old,6 month old and yearling were 7.07,12.75 and 19.69 kg resp,increasing by 11.87%,17.08% and 23.29% resp.than that before selection.The withers height,body length and chest circumference of selected Yinchang white goats were all higher than that before selection at each growth stages.[Conclusion] The growth performance of selected Yinchang white goat was increased,and the breeding effect was obvious.
