摘　　要：本文对天山北坡中段牧民定居点暖季放牧＋冷季舍饲模式下的冬羔生产过程中母羊妊娠、产羔、营养补饲、冬羔生长发育及经济效益进行了生产试验研究。结果表明：①冬羔的繁殖成活率和初生重（Ｐ＜０．０１）分别比春羔高１３．４％、２２．８％。②冬羔平均断奶体重（Ｐ＜０．０１）和６月龄平均体重（Ｐ＜０．０５）分别比春羔高２８．７％、１０．９％，冬羔１０月龄平均体重达到５０ｋｇ以上。③每只冬羔创造的经济价值比春羔高 ３４． １％。This study focused on the process of winter lambing on farmer s settle down area in the middle part of northern Tianshan, where the model of animal raising is now grazing in the warm season and housing in the winter. The gestation, lambing, supplement feeding, lamb growth, and the consequent economic return were also studied. The results showed that the rate of reproduction and newborn weight of winter lamb were about 13. 4 % and 22. 8 % higher (P< 0. 01 ) than that of spring lamb. Similarly, the weanin...
