中文摘要:

为探究野乔菜替代部分精料对从江香猪生长性能、屠宰性能及肉质的影响，试验选取体重约20kg 的从江香猪40 头，随机分为4 组，每组10 头。对照组饲喂基础日粮，试验组以野乔菜替代部分基础日粮，替代比前期分别为10%、20%、30%，后期分别提高到20%、30%、40%。结果表明：野乔菜替代部分精料可显著降低从江香猪平均日增重，减缓生长速度；显著降低6~7 胸椎间膘厚及胴体脂肪比例，显著提高瘦肉率；显著提高肌肉熟肉率，粗蛋白含量随着替代量的升高而提高，肉质得到提高。研究显示，野乔菜替代部分精料可降低从江香猪生长速度，提高胴体品质及肉品质，其适宜替代量为前期20%、后期30%。

英文摘要:

To investigate the effects of partial substitution of concentrate with wild buckwheat on growth，slaughter performance and meat quality in Congjiangxiang pigs，40 Congjiang Xiang pigs were selected and randomly divided into three experimental groups（ each n=10） and one control group with bodyweight of approximately 20 kg.The pigs in control group were fed on concentrate. In the other three treatments，concentrate was substituted with fresh wild buckwheat at 10%-30% at the early fattening stage and 20%-40% at the late fattening stage. The results showed that the partial substitution of concentrate with wild buckwheat significantly decreased the average daily gain（ ADG）of Congjiangxiang pigs，and slowed their growth rate. The backfat thickness and body fat percentage significantly decreased，and the lean meat percentage increased（ P<0.05）. The substitution of wild buckwheat resulted in high cooking percentage（ P<0.05） and crude protein（ P<0.05） of longissimus dorsi muscle. These results indicated that the substitution of concentrate with wild buckwheat slowed the growth rate and improved the carcass quality and meat quality of Congjiang Xiang pigs，and the proportion around 20% at the early fattening stage and 30% at the late fattening stage could get better performance.
