摘要
本试验旨在研究发酵麸皮等量替代基础日粮中5%麸皮对育肥猪生长性能、屠宰性能及肉品质的影响。试验选择90 kg左右的杜×长×大三元杂交育肥猪,随机分为2组,每组6个重复,每个重复1头猪。对照组饲喂基础日粮,试验组将基础日粮中5%麸皮用发酵麸皮替代;预试期7 d,正式试验期26 d。结果表明:与对照组相比,试验组平均日增重显著增加13.49%(P<0.05),平均日采食量无显著差异(P>0.05),耗料增重比显著降低11.73%(P<0.05);与对照组相比,试验组活体瘦肉率1、活体瘦肉率2均无显著差异(P>0.05);试验组屠宰率、第10肋眼肌面积和第10肋背膘厚等屠宰性能指标均差异不显著(P>0.05);与对照组相比,试验组48 h滴水损失降低18.84%(P<0.05),肌内脂肪提高30.4%(P<0.05)。综上分析,发酵麸皮等量替代基础日粮中5%麸皮可以有效提高育肥猪生长性能,改善肉品质。
This experiment was conducted to study the effct of fermented wheat bran fermentation substitution 5% wheat bran in based diet on growth performance slaughter performance and meat quality of finishing pigs. A total of 12 Duroc×Labdrace×Yorkshire finishing pigs, randomly divided into 2 groups of 6 repeats, each repetition 1 pig. Pigs in the control group were fed the basal diet, test group, bran will be replaced by 5% bran fermentation. The pre-test period lasted for 7 days and the trial period lasted for 26 days. The results showed that compared with control group, test group average daily gain（ADG） increased 13.49%（P〈0.05）, Feed/gain decreased 11.73%（P〈0.05）; Compared with the control group, test group drip loss48 h decreased18.84%（P〈0.05）, intramuscular fat increased 30.4%（P〈0.05）.Overall,it showed that fermented wheat bran by replacing 5% bran based diet can improve the growth performance of finishing pigs and improve meat quality.
