摘要
试验旨在研究复方中草药对三黄鸡生长性能、抗氧化能力、屠宰性能及经济效益的影响。选取1日龄三黄鸡288只,完全随机分为4个组,每组6个重复,每个重复12只,其中A组为对照组,B、C、D组分别饲喂0.5%、1.0%、2.0%复方中草药,饲养期56 d。结果显示,第1~56天,相较于A组,B、C组的末重(FBW)、平均日增重(ADG)、平均日采食量(ADFI)均显著提高(P<0.05);各试验组的总超氧化物歧化酶(T-SOD)以及总抗氧化能力(T-AOC)、谷胱甘肽过氧化物酶(GSH-Px)活性均无显著差异(P>0.05),C组的丙二醛(MDA)含量显著降低(P<0.05);试验组的屠宰率、半净膛率、全净膛率、胸肌率、腹脂率均无显著差异(P>0.05),C组的腿肌率显著提高(P<0.05);各试验组的总毛利润和只毛利润均有所提升。综上,本试验用复方中草药能提升三黄鸡的生长性能及屠宰性能,增强抗氧化能力,使三黄鸡能获得更高的经济效益,最佳添加剂量为1.0%。
This experiment was to study the effects of compound Chinese herbal additives on growth performance,antioxidant capacity,slaughter performance and economic benefit of Sanhuang chickens.A total of 2881-day-old Sanhuang chickens were randomly divided into 4 groups with 6 replicates per group and 12 chickens per replicate.Group A was the control group,and groups B,C and D were fed 0.5%,1.0%and 2.0%compound Chinese herbs,respectively,for 56 days.The results showed as follows:from day 1 to day 56,compared with group A,FBW,ADG and ADFI in groups B and C were significantly increased(P<0.05);there were no significant differences in T-SOD,T-AOC and GSH-Px activities in experimental groups(P>0.05),but MDA content in group C was significantly decreased(P<0.05).There were no significant differences in slaughter rate,half evisceration rate,full evisceration rate,chest muscle rate and abdominal fat rate in experimental groups(P>0.05),while leg muscle rate in group C was significantly increased(P<0.05).The total gross profit and average gross profit of the experimental group were improved.In conclusion,the compound Chinese herbs used in this experiment can improve the growth performance and slaughter performance of Sanhuang chickens,enhance the antioxidant capacity,and make Sanhuang chickens obtain higher economic benefits,the optimal additive dosage is 1.0%.
