An experimental study on introduction, breeding, improvement and utilization of Boer goats

1996年 ,河南波尔种畜实业公司在全国率先从新西兰引进 73只波尔山羊 ,通过几年的饲养观察 ,纯种羔羊平均初生重3 9kg ,波×槐杂交一代、二代平均初生重 2 8kg、3 4kg,波×奶杂交一代、二代初生重 3 0kg、3 8kg ,分别比槐山羊、奶山羊提高 86 %、75 8%和 93%、82 %。波×槐、波×奶杂交一代平均成年体重分别比槐、奶山羊提高 76 %、6 0 %。引进 6 3只母羊第一胎繁殖率 185 7% ,双羔率 83% ;12月龄波×槐、波×奶杂交一代屠宰率分别是 4 6 8% ,5 0 2 % ,比槐、奶山羊提高 15个、13个百分点。

In 1996, Henan Boer Breeding Animal Industrial Company became the first in the country to introduce 73 Boer goats from New Zealand. Several years of feeding observations indicated average birth weights of 3.9 kg for purebred lambs, 2.8 and 3.4 kg for first and second filial generations of Boer×Huai, and 3.0 and 3.8 kg for first and second filial generations of Boer×Dairy goats, which were 86%, 75.8%, 93% and 82% higher than those of Huai and Dairy goats, respectively. The F1 offspring of Boer×Huai and Boer×Dairy were 76% and 60% higher in average mature weight than Huai and Dairy goats, respectively. The 63 introduced does had a fertility rate of 185.7% and twinning rate of 83% at first parity. Twelve-month-old Boer×Huai and Boer×Dairy F1 offspring has dressing percentages of 46.8% and 50.2%, which were 15% and 13% higher than Huai and Dairy goats, respectively.
