摘要： 为建立羔羊短期最佳经济育肥饲养模式，以子午岭黑山羊羔羊作为研究对象，采用全价颗粒饲料（试验组）和当地配合饲料（对照组）进行短期育肥试验，观测其生长性能、屠宰性能和肉品质。生长结果表明：试验组羔羊的生长性能、胴体重和屠宰性能均高于对照组（P>0.05），试验组和对照组的育肥期增重分别是5.15 kg和4.51 kg，胴体重分别是10.54 kg和9.88 kg，屠宰率分别是49.63%和48.31%。肉品质测定结果表明：试验组的部分肉品质优于对照组，试验组的失水率比对照组低5.4%（P<0.01），熟肉率比对照组高8.15%（P<0.01）。经济效益分析结果表明：试验组每只羔羊的纯收益较对照组高16元。由此说明，用全价颗粒饲料短期育肥子午岭黑山羊羔羊的效果较优。

Abstract: In order to set up a short-term and best economic fattening lamb feeding mode, this paper took Ziwuling black goat lambs and 2 different feeds, a complete pelleted diet (experimental group), and a local formulated feed (control group) as investigation target, for a short time finishing experiment to observe its growth performance, carcass capability and meat quality. The results indicated that the lamb of experimental group had better growth and carcass traits than that of control group (P>0.05). The live weight gains were 5.15 kg and 4.51 kg, respectively; the carcass weight were 10.54 kg and 9.88 kg, respectively; and the dressing percentage were 49.63% and 48.31%, respectively. Meat quality of the experimental group was superior to that of the control group, while driage of the experimental group was 5.4% (P<0.01), lower than that of control group; and its cooked meat percentage was 8.15% (P<0.01), higher than that of the control group. The economic benefit analysis revealed that net profit of per lamb was 16 yuan more than that of control group. These results indicated that using complete pellet feed to fatten Ziwuling black goat lamb had a better effect.
