摘　　要：为确立放牧藏羊有效补饲时间,对两组营养水平相近,牧养方式相同的藏羊,在不同时段2022年10月2日至2022年12月30日(试验一),2023年1月1日至2023年3月31日(试验二)补饲相同量饲料,开展不同时段补饲试验。从增重效果分析,试验一全期平均总增重4.50 kg,较试验二全期平均总增重3.9 kg多增重0.6 kg,补饲效果较好。从补饲效益分析,试验一只均增加收益57.15元,试验二只均增加收益58.65元,试验一补饲效益稍低于试验二,但无显著差异。从生态效益分析,通过暖季草原适度放牧与冷季半舍饲补饲育肥相结合,实现藏羊12月龄出栏,可减轻冷季草场压力,促进草原畜牧业生产经营方式改变,使甘南牧区生态良好、生产发展、生活富裕、社会和谐。综合经济生态效益得出:放牧藏羊适时补饲是高寒牧区草原畜牧业从“靠天养畜”向“科学牧养”转型发展,产业提质增效的有效途径。试验一(补饲时段10月至12月)为12月龄藏羊补饲育肥效益最大化时段。To establish an effective supplementary feeding time for grazing Tibetan sheep,two groups of Tibetan sheep with similar nutritional levels and the same grazing methods were supplemented with the same amount of feed at different time periods from October 2,2022 to December 30,2022(experiment 1)and from January 1,2023 to March 31,2023(experiment 2).From the analysis of the weight gain effect,the average total weight gain during the entire period of experiment 1 was 4.50 kg,which was 0.6 kg more than the average total weight gain of 3.9 kg during experiment 2.The supplementary feeding effect was better.From the analysis of the benefits of supplementary feeding,experiment 1 increased the income by 57.15 yuan per animal,while experiment 2 increased the income by 58.65 yuan per animal.The supplementary feeding benefits of experiment 1 were slightly lower than those of experiment 2,but there was no significant difference.From the perspective of ecological benefits analysis,by combining moderate grazing on warm season grasslands with semi captive feeding and fattening in cold season,it is possible to achieve the slaughter of Tibetan sheep at the age of 12 months,which can reduce the pressure on cold season grasslands,promote changes in the production and operation mode of grassland animal husbandry,and make the Gannan pastoral area ecologically sound,productive,prosperous,and socially harmonious.Based on the comprehensive economic and ecological benefits,it can be concluded that timely supplementation of grazing Tibetan sheep is an effective way for the transformation and development of grassland animal husbandry in high-altitude pastoral areas from“relying on the nature”to“scientific animal husbandry”,and to improve the quality and efficiency of the industry.experiment 1(supplementary feeding period from October to December)is the period during which the maximum benefit of supplementary feeding and fattening is achieved for 12-month-old Tibetan sheep.
