山花黄芩提取物对肉鸡生长性能、抗氧化性能及肉品质的影响

Effect of supplementation SMF on growth performance,oxidation resistance and meat quality of broiler chicks

试验旨在研究山花黄芩提取物(SMF)对肉鸡生长性能、抗氧化性能及肉品质的影响。将180只1日龄的爱拔益加(AA)肉鸡(公雏)随机分为3组(对照组、阳性对照组、试验组),每组6个重复,每个重复10只鸡。阳性对照组饲喂添加125 mg/kg恩拉霉素(8%)的饲粮,试验组(SMF组)饲喂500 mg/kg SMF的饲粮,试验期1-42日龄。结果表明:SMF可在一定程度上提高1-21日龄平均日增重(ADG)3.47%(P>0.05),降低料重比(F/G)0.74%(P>0.05),降低死淘率100%(P>0.05);SMF可提高21-42日龄ADG 4.99%(P>0.05)、降低(F/G)4.41%(P>0.05),降低死淘率50.07%(P>0.05);SMF可在一定程度上提高1-42日龄ADG 3.10%(P>0.05),降低F/G 1.69%(P>0.05),显著降低死淘率66.70%(P<0.05)。SMF可显著提高21 d肉仔鸡血清总抗氧化能力(T-AOC)(P<0.05),显著提高42 d肉仔鸡血清谷胱甘肽过氧化物酶(GSH-Px)水平(P<0.05)和超氧化物歧化酶(SOD)水平(P<0.05),且均优于抗生素组;SMF可在一定程度上降低42 d肉仔鸡胸肌滴水损失、蒸煮损失及剪切力。由此可知,SMF对肉鸡1-42 d的生长性能、抗氧化性能及胸肌肉品质具有较好的提高作用,且可在一定程度上替代恩拉霉素。

The experiment was conducted to evaluate SMF on growth performance,oxidation resistance and meat quality of broiler chicks aged from 1-42 days.180 healthy male broilers(AA)at one-day-old were randomly allotted into three groups with six replicates in each group,and ten broiler chicks per replicate.Chicks were fed a basal diet supplemented with 125 mg/kg enramycin,500 mg/kg SMF.The experiment lasted for 42 days.The result showed that,SMF increased ADG 3.47%during 1-21 days(P>0.05),F/G and mortality decreased by 0.74%and 100%during 1-21 days(P>0.05).SMF increased ADG 4.99%during 21-42 days(P>0.05),F/G and mortality decreased by 4.41%and 50.07%during 21-42 days(P>0.05).SMF increased ADG 3.10%during 1-42 days(P<0.05),F/G and mortality decreased by 1.69%(P>0.05)and 66.70%(P<0.05)during 21-42 days.SMF significantly increased T-AOC at 21 days(P<0.05),GSH-Px and SOD at 42 days(P<0.05).SMF decreased the drip loss,cooking loss and shear force in some degree.Diet supplemented with 500 mg/kg SMF can improve growth performance,antioxidant performance and meat quality,it is an alternative to enramycin in some degree.
