摘 要:以混播人工草地放牧苏尼特羊为样本,在相同载畜量条件下,连续3年测定连续放牧与划区轮牧两种不同管理模式下羊只的生产性能变化并分析成本与收益趋势。结果表明,试验羊体重、销售收入的最佳时间点为每年的9月初;销售收入随放牧年限增加而增加,但以当年9月出栏经济效益较佳。划区轮牧效益与收入均优于连续放牧,3年的纯收入分别高74.80元/只、39.38元/只和62.26元/只,销售收入分别高77.66元/只、32.56元/只和85.14元/只。商品羊成本主要由羔羊、人工、冬春季节补饲料三部分构成,占总成本95%。降雨量减少造成牧草产量下降,缩小了划区轮牧和连续放牧间的差异。This study was to investigate the sheep production and cost-benefit trend of different grazing regime. Sunite wether grazed on mixed artificial pasture was taking as the object of study with the same carrying capacity, the production performance of Sunite wether under two different management modes of continuous grazing and rotational grazing were measured for three consecutive years and the cost-benefit trend was analyzed.The results showed that the best time for weight and sales revenue of tested wether was early September, and sales revenue increased with the increase of grazing years, but the economic benefit was better in September of that year. The benefit and income of rotational grazing were both better than that of continuous grazing. In the three years, the benefits of each Sunite wether in rotation grazing regime were 74.80 yuan, 39.38 yuan and 62.26 yuan higher than that of continuous grazing regime, the income of each wether in rotation grazing regime was 77.66 yuan, 32.56 yuan and 85.14 yuan higher than that of continuous grazing regime. The cost of commodity sheep was mainly composed of lamb, labor and supplement feedstuff in winter and spring, accounting for 95% of the total cost. The decrease of rainfall resulted in the decrease of forage yield, which reduced the difference between rotational grazing and continuous grazing.
