无角陶赛特×小尾寒羊杂交一代育肥试验

Fattening Experiment of Poll Dorset×Small-tail Han Sheep

选择3月龄左右的无角陶赛特与小尾寒羊杂交一代羔羊12只,以相同月龄的12只小尾寒羊为对照,研究舍饲条件下,陶寒和小尾寒羊短期育肥的效果。结果表明,育肥末陶寒平均日增重显著高于小尾寒羊(P<0.05);陶寒在体长、胸围和管围上均显著高于小尾寒羊(P<0.05);从经济效益来看,陶寒组与小尾寒羊组相比,每只羔羊可多赢利57.60元。

12 crossed lambs （3 months）of Poll Dorset X Small-tail han sheep （DH） and 12 lambs of small-tail han sheep （HH） of the same age were divided into two groups to investigate the effects of short-term fattening with yard feeding. The resuits showed that the average daily gain of DH was signifancantly higher than HH （P〈0.05）;body length, chest girth and Cannon girth of D H were signifancantly higher than HH （P〈0.05） ; from view of economic benefit, compared with HH, the profit of every DH increased by 57.60 yuan.
