肉用羔羊肥育试验

用波德代羊和无角陶塞特羊与当地蒙系羊的杂种一代羔羊各 70 只,以当地相同月龄蒙系羔羊为对照,采取全舍饲的方式进行 60 d 短期肥育。结果表明:5月龄组波德代和陶塞特杂种羔羊日增重最高达 288 g/d 和 285 g/d,极显著(P<0.01)高于对照组(186 g/d),饲料转化率是对照组的 1.5~2.5 倍,经济效益是对照组的 2.6~5.2 倍;3月龄组波德代和陶塞特杂种羔羊日增重最高达 317 g/d 和 235 g/d,也极显著(P<0.01)高于对照组(183 g/d),饲料转化率是对照组的 1.5~2.0 倍,经济效益是对照组的 1.7~3.8 倍。

Experiment of feeding on mutton lamb

Adopting barn feeding to fat 140 hybrid lambs including male, castrate and female which is crossed by Borderdale and Poll Dorset (♂) introduced from New Zealand and Mongolia sheep (♀) contrasting with 14 lambs from local Mongolia sheep. The result showed the increasing of Borderdale male hybrid lambs (treat group) was 288 g/d and Poll Dorset male hybrid lambs was 285 g/d ,which was higher (P<0.01) than control group(186 g/d), the treat group had 1.5~2.5 times as control group in feed conversion, the economy benefits of treat group was 2.6~5.2 times higher than control group in the 5-month old lamb group; In the 3-month old lamb group the increasing of Borderdale male hybrid lambs was317 g/d and Poll Dorset male hybrid lambs was 235 g/d ,which was also higher (P<0.01)than control group (183 g/d), the treat group had 1.5~2.0 times as control group in feed conversion, the economy benefits of treat group was 1.7~3.8 times as control group.
