Abstract
After tested female sheep were treated by using vaginal sponge method and pregnant mare serum, male Dorper sheep and male Bamei sheep were improved by three-way cross with female Bahan F1 hybrid sheep and female Duhan F1 hybrid sheep by using artificial insemination, meanwhile male small-tail Hart sheep of the same age was mated with female small-tail Han sheep, which was taken as control. The improvement effect was observed. Results showed that the conception rate and lambing rate of female FI hybrid sheep were lower than that of small-tail Han sheep; but in the aspect of production performance, the average birth weight and the weight at 1 month of age of F2 three-way hybrid sheep were increased by 1.68 kg and 2.02 kg compared with local small-tail Han sheep; under the same feeding and management conditions, the height at withers, body length and heart girth F2 three-way hybrid sheep were higher than that of local small-tail Han sheep. Therefore, the improvement effect was obvious when male Dorper sheep and male Bamei sheep were improved by three-way cross with female Bahan Fi hybrid sheep and female Duhan Fl hybrid sheep.关键词
