饲粮中添加三七渣对西畴乌骨鸡生长性能、血清生化指标及肉品质的影响

Effects of Panax notogineng reidue on growth performance,serum biochemical indexes,and meat quality of Xichou Wugu chickens

试验旨在研究在饲粮中添加三七渣对西畴乌骨鸡生长性能、血清生化指标及肉品质的影响。将270只体重相近、28日龄的西畴乌骨鸡分为3组,每组5个重复,每个重复18只西畴乌骨鸡,公、母各半。对照组饲喂基础饲粮,试验Ⅰ组、Ⅱ组分别在基础饲粮中添加4%和8%的三七渣。预试期7 d,正式试验期为60 d。结果显示:与对照组相比,试验Ⅱ组料重比显著降低(P<0.05),肌肉氨基酸总量显著提高(P<0.05);试验Ⅰ组、Ⅱ组平均日采食量、血清甘油三酯、肌肉粗脂肪和饱和脂肪酸含量均显著降低(P<0.05),试验Ⅰ组、Ⅱ组肌肉水分、不饱和脂肪酸、必需脂肪酸含量显著提高(P<0.05)。研究表明,饲粮中添加三七渣可以提高西畴乌骨鸡生长性能,改善血清生化指标和肉品质,西畴乌骨鸡生产中添加4%的三七渣较为适宜。

The experiment aimed to investigate the effects of adding Panax notogineng residue to the feed on the growth performance,serum biochemical indexes,and meat quality of Xichou Wugu chickens.A total of 270 Xichou Wugu chickens with similar body weight and 28 days old were divided into three groups,with five replicates per group,each replicate consisted of 18 Xichou Wugu chickens,half in male and female.The control group was fed a basic diet,while the experimental groupⅠand groupⅡwere supplemented with 4%and 8%Panax notogineng residue in the basic diet,respectively.The pre-test lasted for seven days and the experiment lasted for 60 days.The results showed that compared to the control group,the feed to gain ratio was significantly reduced in groupⅡ(P<0.05),and the total muscle amino acids were significantly increased(P<0.05).The average daily feed intake,serum triglycerides,muscle fat,and saturated fatty acid content in groupⅠand groupⅡwere all significantly decreased(P<0.05).the muscle moisture,unsaturated fatty acids,and essential fatty acid content were significantly increased in groupⅠand groupⅡ(P<0.05).The study indicates that the addition of Panax notogineng residue to the feed can improve the growth performance,improve serum biochemical indexes,and enhance the meat quality of Xichou Wugu chickens,the addition of 4%Panax notogineng residue is the more suitable.
