酸化剂与益生菌混合制剂对广西三黄鸡生长性能、屠宰性能及肉品质的影响

试验旨在研究日粮酸化剂与益生菌混合制剂对广西三黄鸡生长性能、屠宰性能及肉品质的影响。试验选取2 400只84日龄的广西三黄鸡,并将其随机分为A、B、C、D四组,每组设置3个重复,每个重复200只鸡。A组(对照组):基础日粮;B组:基础日粮+1 g/kg混合制剂;C组:基础日粮+2 g/kg混合制剂;D组:基础日粮+0.1 g/kg恩拉霉素。结果表明:试验组平均日采食量均高于对照组,其中C、D组显著高于A组(P<0.05);试验组的屠宰率均高于对照组,其中C组显著高于A组(P<0.05);试验组胸肌和腿肌的滴水损失均低于对照组,其中C组显著低于A组(P<0.05);D组腿肌的剪切力显著高于其他3组(P<0.05);试验组胸肌和腿肌的肌内脂肪均高于对照组,其中B组胸肌的肌内脂肪显著高于A组(P<0.05)。综上所述,在日粮中添加2 g/kg酸化剂与益生菌混合制剂,有助于提高三黄鸡的生长性能和屠宰性能,并能通过降低滴水损失来改善肉质。

Effect of the mixture of acidifier and probiotics on the growth performance,slaughter performance and meat quality of Sanhuang chicken in Guangxi

The purpose of the experiment was to study the effect of dietary acidifier and probiotics on the growth performance, slaughter performance and meat quality of Guangxi Sanhuang chicken. 2 400 Guangxi Sanhuang chickens aged 84 days were randomly selected and divided into groups A, B, C and D, with three replicates in each group, 200 chickens per replicate. GroupA(control group): basal diet;group B: basal diet+1 g/kg mixed preparation;group C: basal diet+2 g/kg mixed preparation;group D: basal diet+0.1 g/kg of enramycin. The results showed that: average daily feed intake in the test group was higher than that in control group, and that in group C and D was significantly higher than that in group A(P<0.05). The slaughter rate of the experimental group was higher than that of control group, with group C significantly higher than group A(P<0.05). The dripping loss of pectoral muscle and leg muscle in the test group was lower than that in control group, and that in group C was significantly lower than that in group A(P<0.05). The shear force of leg muscles in group D was significantly higher than that in the other three groups(P<0.05). The intramuscular fat of pectoralis and leg muscle in the test group was higher than that in control group, and intramuscular fat of pectoralis muscle in group B was significantly higher than that in group A(P<0.05). In summary, the addition of 2 g/kg of acidifier and probiotics in the diet can improve the growth performance and slaughter performance of Sanhuang chicken, and can improve the meat quality by reducing the drip loss.
