摘要
对8岁新疆驴和关×新F1(关中驴×新疆驴)进行了产肉性能测定,结果表明,在相同的饲养环境条件下,关×新F1驴与新疆驴相比,F1公驴的体高、体重和胴体重分别提高了16.44%、35.02%和39.52%,杂交优势极显著(P<0.01);F1母驴体高、体重和胴体重分别提高了18.01%、30.44%和38.23%(P<0.01)。
The experiment determined the performance of meat yield of Xinjiang donkey and Guan-Xin dondey （short for Guan-Xin） cross breeding donkey. The result indicates that for male the body indexes of the first filial generation are 16.44% ,35.02 % and 39.52% higher than that of Xinjiang donkey ,for male , and for female 18.01% . 30. 44% and 38.23% higher. The result is extraodinary different （ P 〈 0.01 ）. The meat yield performance of Guan-Xin cross breeding donkey is distinctly improved.
