摘要/Abstract

摘要： [目的]研究内蒙古阿尔巴斯白绒山羊羔羊短期育肥效果,并评价育肥羊的屠宰性能。[方法]选择体重相近的4月龄断奶羔羊520只,选取260只作为试验组,采取全舍饲的饲养模式,分别在3个牧户家饲养,饲养管理标准与饲料保持一致;选取260只作为对照组,采取传统放牧饲养模式,选择草场质量相近的2个牧户家饲养。育肥期为4个月。测定、计算并比较不同饲养模式下阿尔巴斯白绒山羊在不同育肥阶段的体重以及平均日增重;育肥结束后进行屠宰试验,测定并比较不同饲养模式下阿尔巴斯白绒山羊的屠宰性能指标;计算不同饲养模式下阿尔巴斯白绒山羊的养殖经济效益。[结果]与对照组相比,试验组在育肥120 d的体重显著（P<0.05）高于对照组;试验组在育肥30~60 d、60~90 d的平均日增重显著（P<0.05）高于对照组,在育肥90~120 d的平均日增重极显著（P<0.01）高于对照组。试验组宰前活重、胴体重、屠宰率、净肉重、净肉率、骨骼重、肾脏及肾脂重量、眼肌面积均极显著（P<0.01）高于对照组,骨肉比极显著（P<0.01）低于对照组;在非胴体组成部分重量方面,试验组血重、头蹄重、皮重、消化系统重（胃、肠）、内脏重（心、肝、肺）、大网膜脂肪及肠系膜脂肪重均极显著（P<0.01）高于对照组。试验组育肥纯利润较对照组增加345.60元/只。[结论]阿尔巴斯白绒山羊舍饲育肥与传统放牧模式相比,育肥增重效果和屠宰性能显著提高,取得了良好的经济效益,适合在鄂尔多斯市推广。

Abstract: [Objective] To assess the short-term fattening effect and slaughter performance of Inner Mongolia Arbas white cashmere goat kids. [Method] A total of 520 four-month-old weaned goat kids with similar weights were selected. Among them, 260 kids （experimental group） were fattened under whole confined farming mode in 3 separate herdsmen′s families with the same feeding management standards and feed supply, and the remaining 260 kids （control group） were raised under traditional grazing mode in 2 separate herdsmen′s families with similar pasture quality. The fattening period lasted for 4 months. The weights and average daily gains at different fattening stages under different feeding modes were measured, calculated and statistically compared; a slaughter test was carried out at the end of the fattening experiment to assess the effect of different feeding modes on slaughter performance indicators of Arbas white cashmere goats. The economic benefits of different feeding modes were calculated and compared. [Result] Compared with the control group, the weights on 120^th day of fattening experiment of the experimental group were significantly （P<0.05） increased; the average daily gains during 30 to 60 days and 60 to 90 days of the experimental group were significantly （P<0.05） increased, and those during 90 to 120 days of the experimental group were extremely significantly （P<0.01） increased. The live weights before slaughter, carcass weights, slaughter rates, net meat weights, net meat rates, bone weights, kidney and kidney fat weights, and eye muscle areas of the experimental group were extremely significantly （P<0.01） higher than those of the control group, while the bone-meat ratio of the experimental group was extremely significantly （P<0.01） lower than that of the control group. Non-carcass components such as the blood weights, head and hoof weights, tare weights, digestive system weights （stomach and intestine）, visceral weights （heart, liver, lung）, and omental fat and mesentery fat weights of the experimental group were extremely significantly （P<0.01） higher than those of the control group. The fattening net profit of the experimental group was 345.60 yuan/head higher than that of the control group.[Conclusion] Compared with the traditional grazing mode, the weight gain and slaughter performance of Albas white cashmere goats fattened under whole confined farming mode are significantly improved, and good fattening economic benefits are achieved. The whole confined fattening mode is suitable for promotion in Ordos City.
