摘　　要：为了提高环县绒山羊冬季饲养效果,把6月龄的子午岭黑山羊羔羊和辽宁绒山羊(♂)×子午岭黑山羊(♀)杂种一代羔羊(简称F1代羔羊)作为试验对象,以环县农民群众传统采用的饲养模式——放牧加少量补饲(简称"放牧+补饲")作为对照,采用全舍饲方式对两个试验群体进行60d的育肥试验,综合测定绒山羊羔羊的生长结果、屠宰性能和肉品质指标,计算经济效益。结果表明,在两个试验群体内,全舍饲组的育肥末重、育肥期增重、平均日增重、胴体重和屠宰率均极显著高于"放牧+补饲"组(P<0.01)。子午岭黑山羊羔羊全舍饲组的平均日增重、胴体重和屠宰率分别是102.5g、10.75kg和47.66%,分别较"放牧+补饲"组提高了87.2g、3.46kg和12.54%。F1代羔羊全舍饲组的平均日增重、胴体重和屠宰率分别是117.2g、11.71kg和49.62%,分别较"放牧+补饲"组提高了96.7g、4.16kg和13.83%。全舍饲组的失水率和嫩度显著低于"放牧+补饲"组(P<0.05),其它肉品质指标在全舍饲和"放牧+补饲"组间无显著差异(P>0.05)。子午岭黑山羊羔羊和F1代羔羊全舍饲组的纯收入较"放牧+补饲"组同类型羔羊分别提高了110.2和75元。因此,较传统饲养模式,全舍饲育肥能够明显增加环县绒山羊羔羊冬季生长效果和产肉性能,改善部分肉品质,显著提高养殖效益。We conducted yard-feeding experiments on goats in order to improve the methods for raising and breeding of cashmere goats in Huanxian County in winter.The traditional method in Huanxian County of＂grazing and supplementary feeding＂（hereafter,GS）served as the control group.A 60-day yard-feeding（hereafter,Y）experiment was conducted using six-month-old Ziwuling black goats and F1 hybrids of Liaoning Cashmere goats（♂）×Ziwuling black goats（♀）（hereafter,F1）.Growth results,slaughter performance,and meat quality were systematically measured and economic return was calculated.The final weight,weight gain,average daily gain,carcass weight and dressing percentage in Y group were higher than those in GS group in both experimental goat populations（P〈0.01）.Average daily gain,carcass weight,and dressing percentage of Ziwuling black goats in Y group were 102.5g,10.75 kg,and 47.66%,respectively,which were higher than the corresponding values of 87.2g,3.46 kg,and 12.54% in GS group.Average daily gain,carcass weight,and dressing percentage of F1 in Y group were 117.2g,11.71 kg,and 49.62%,respectively;these values were also higher than the corresponding values of 96.7g,4.16 kg,and 13.83%in GS group.Water loss rate and meat tenderness in Y group were lower than those in GS group（P〈0.05）,but no significant differences were observed between these groups with regard to other meat quality indexes.Net income of Y group from Ziwuling black goats and F1 hybrids were 110.2and 75 CNY,respectively,higher than those of lambs of the same breed in GS group.These results suggest that yard-feeding can increase growth results and meat performance,and improve some meat quality indexes and cultural benefits of the cashmere goats of Huanxian County in winter.
