木寡糖益生素和益生素对广东麻鸡屠宰性能及肌肉品质的影响

120羽广东麻鸡,随机分成A、B、C 3组,每组40羽。A组在日粮中添加0.3%木寡糖益生素,B组在日粮中添加0.3%益生素,C组作为对照组,饲喂8周,每组选4羽屠宰、测定。试验结果表明:日粮中添加木寡糖益生素和益生素在提高屠宰率、胸肌率方面比C组分别提高了2.3%、2.0%,差异显著(P<0.05),在滴水损失方面比对照组分别降低了25.0%、28.8%,差异显著(P<0.05),添加木寡糖益生素组失水率比对照组降低了19.6%(P<0.05),对pH值、熟肉率、嫩度差异不显著。

Effect of Xylooligosaccharides Probiotics and Probiotics on Slaughter Performance and Meat Quality in Guangdong Hemp Chicken

To study the effect of xylooligosaccharides probiotics and probiotics on slaughter performance and meat quality in Guangdong hemp chicken,120 one-day-old Guangdong hemp chickens were randomly divided into 3 groups and the experiment period was 8 weeks.The diets of the groups A and B were supplemented with 0.3% xylooligosaccharides probiotics and 0.3%probiotics respectively,and group C as control.The results demonstrated that xylooligosaccharides probiotics and probiotics increased the slaughter rate and the breast meat rate by 2.3% and 2.0%,(P<0.05),and decreased the weeping loss by 25.0% and 28.8%,respectively,xylooligosaccharides probiotics decreased the dehydration rate by 19.60%(P<0.05),influences on pH value,cooking loss and tenderness were not significant.
