摘　　要：【目的】以天山北坡中段牧区生产母羊为研究对象,研究在冷季对其采用不同的补饲时间和产羔时间条件下对绵羊生产效益的影响。【方法】在昌吉州阿什里乡选择6户草场类型一致,绵羊体况相近的牧户,对所选牧户的600只生产母羊诸项生产性能(实验户300只、对照户300只)进行监测。【结果】(1)冬羔初生重、1~3月龄体重及成活率显著高于春羔;(2)试验组母羊越冬体重损失极显著小于对照组母羊;(3)试验组母羊的受胎率98%和产羔率97%都极显著高于对照组88%和87%(P<0.01)。(4)试验组收入/成本高于对照组,且出售每只羔羊可多收入109元。【结论】补饲时间和产羔时间对当地养羊业的生产效益有明显的影响。[Objective] The project aims to ~search the effect of sheep production efficiency on the different supplementary feeding time and lambing time conditions in the northern slope of Tianshan Mountains in the cold season.[Method] 6 households that their grassland types and sheep body conditions were similar in Ashili Township of Changji P^fectme we~ selected and the production performance of the 600 selected ewes in the 6 households was monitored （300 sheep in the tested households and another 300 in the control households）.[Result] （1） Winter lamb birth weight,the weight from January to March and survival rate was significantly higher than that of spring lamb; （2） The test group of ewes overwintering weight loss was significantly lower than that of the control group of ewes; （3） The 98 % conception rate and the 97 % lambing rate of the test group ewes were significantly higher than those 88% and 87% of the control group （P 〈 0.01） ;（4） The income/cost of the test group was higher than that of the control group,and the income from the sale of each lamb was 109 yuan higher than that from the control group.[Conclusion] Supplementary feeding time and lambing time had a significant effect on the local sheep industry production efficiency.
