为了更好地保护和开发利用安徽白山羊遗传资源,本研究以合肥博大牧业科技开发有限公司种羊场2009年以来的1200只安徽白山羊新品系为试验材料,同等条件下饲养,并对该新品系山羊的初生、3月龄、6月龄、8月龄、12月龄、18月龄、24月龄的体重、体尺等生长发育指标进行测定.结果表明,安徽白山羊公母羊在18月龄以前生长发育较快,但随着月龄的增加而降低,到24月龄以后除体重、胸围、管围有所增加外,体长、体高变化不大;安徽白山羊新品系成年公母羊的平均体重分别为55.3 kg和45.6 kg,比原安徽白山羊成年公母羊的平均体重(30 kg 和22 kg)提高84.33%和107.27%.试验结果揭示了安徽白山羊新品系群的生长发育规律,为进一步进行安徽白山羊选育和生产提供参考资料.

In this paper, we investigated new line of Anhui white goat in the farm of Hefei Bo Da Livestock Technology Development CO, LTD, to conserve and utilize this genetic resource. Breeding characteristics of 1 200 Anhui white goats at the age of 0 month, 3 months, 6 months, 8 months, 12 months, 18 months and 24 months were tested. The results indicated that the body length, body weight, body height, chest girth and rump width in Anhui white goat showed the highest growth performance before the age of 18 months, and the body length and height changed slightly after the age of 24 months except for body weight, chest girth and cannon cir-cumference;the average weight of the adult rams and ewes in new line were 55.3 kg and 45.6 kg, 84.33%and 107.27%respectively higher than that of the local Anhui white goat (30 kg and 22 kg). This study also provides basic data for further guidance in breeding sheep production.
