摘　　要：选择48头陆川猪阉公猪作为试验动物,研究陆川猪耐粗饲能力。结果表明,使用统糠作为主要纤维源,将陆川猪阉公猪日粮中粗纤维含量由6.5%提高到10.5%,除对陆川猪阉公猪的胴体重量、大理石纹评分影响显著外(P<0.05),其他指标差异不显著(P>0.05)。而将陆川猪阉公猪日粮中粗纤维含量由6.5%提高到14.5%,显著降低了平均日增重、宰前体重、胴体重量、眼肌面积、大理石纹评分、肌内脂肪含量(P<0.05),显著提高了料重比、6～7肋处膘厚和背最长肌水分(P<0.05)。48 Luchuan pigs were used to study on the ability of coarse feeding resistance. The results showed that the level of crude fiber increased from 6.5% to 10.5%, there were signifi- cant differences in carcass weight, marbling scores（P〈0.05）, there were no significant differ- enced in other indexes（P〉0.05）. When dietary fiber increased from 6.5% to 14.5%, signifieantly reduced the average daily gain（ADG）, body weight, body weight before slaughter, loin eye muscle area, marbling scores, intramuscular fat content（P〈0.05）, significantly improved feed/gain（F/G）, 6-7 rib fat thickness and the moisture content of longest back muscle（P〈0.05）.
