摘　　要：试验旨在研究不同水平蚕沙对新西兰兔肉品质的影响。选取120只健康、体重相近(1.06 kg±0.09 kg,公、母各半)的35日龄断奶新西兰兔,随机分为5组,每组6个重复,每个重复4只。对照组饲喂基础日粮,试验组分别饲喂添加6%、12%、18%和24%蚕沙的日粮。试验结束后,每组选取接近平均体重的4只兔(公、母各半)屠宰,测定肌肉品质指标。结果显示,不同水平蚕沙对新西兰兔肉品质有一定影响,其中各组肉色、pH、失水率和蒸煮率差异不显著(P>0.05),而剪切值试验组显著低于对照组(P<0.05),且随蚕沙添加量的增加呈减小的趋势;在化学性状中各组水分、粗蛋白质、粗脂肪、灰分含量差异不显著(P>0.05)。A feeding trial was conducted to study effect of different levels of silkworm feces on meat quality of New Zealand rabbit.120 only 35 day-old weaning New Zealand rabbits with similar initial body weight（1.06 kg±0.09 kg） were randomly assigned to 5 groups with 6 replicates per group.The control group was fed basal diet while the treatment groups were fed diets added 6%,12%,18% and 24% silkworm feces,respectively.After the experiments were completed,4 only rabbits with close to the average weight were chose from each group and slaughtered.Finally,determined the muscle quality indicators.The results showed that different levels of silkworm feces had some effects on meat quality of New Zealand rabbit,the physical traits of five groups of fleshcolor,pH,lossing rate of water,cooking rate had no significant difference（P〉0.05）,shear force of the treatment groups was significantly lower than those of the control group（P〈0.05）,and there was a decreasing tendency of shear force content with increasing content of silkworm feces;the chemical traits of five groups of moisture,crude protein,crude fat,crude ash content had no significant difference（P〉0.05）.Silkworm feces in 6% to 18% added groups were higher than those in control group（P〉0.05）and silkworm feces in 12% was the highest.Fat content of every group was lower than that in control group.
