The effect of adding compound plant essential oils to the diet on the production performance,slaughter performance,meat quality,and immune function of Xiaoyou chickens
摘要
Abstract
In order to study the effects of adding compound plant essential oils to feed on the production performance,slaughter per-formance,meat quality,and immune function of Xiaoyou chickens,150 1-day-old Xiaoyou chickens were selected and randomly di-vided into 5 groups.Compound plant essential oils were added to the basic diet at doses of 100 mg/kg,200 mg/kg,300 mg/kg,and 400 mg/kg for a 52 day feeding experiment,and evaluate the effects of compound plant essential oils.Result:(1)Compared with the control group,there was a significant difference(P<0.05)in body weight at 52 days of age among experimental groups Ⅱ,Ⅲ,and Ⅳ.Experimental group I had a lower body weight,which was significantly different from other experimental groups(P<0.05);The feed to weight ratio of experimental groups Ⅱ,Ⅲ,and Ⅳ decreased significantly.(2)Compared with the control group,the slaughter rate of experimental group Ⅲ increased by 4.59％,with a significant difference(P<0.05),and there was no significant difference between the experimental groups(P>0.05);The half evisceration rate of group Ⅳ increased by 1.19％,with significant differences(P<0.05),while there was no significant difference between the experimental groups(P>0.05);There was a significant difference(P<0.05)in the total e-visceration rate between group Ⅲ and group Ⅳ.Among them,group Ⅲ increased by 2.59％,group Ⅳ increased by 2.53％,and group Ⅰ had the lowest evisceration rate,but there was no significant difference(P>0.05);The breast muscle rate of group Ⅲ increased by 1.12％,with significant differences(P<0.05),while the differences in other experimental groups were not significant(P>0.05).(3)Com-pared with the control group,the shear force of group Ⅲ increased by 6.34,and group Ⅳ increased by 7.48,with significant differ-ences(P<0.05);There was no significant difference in cooking loss(P>0.05);There was a significant difference in meat color brightness between group Ⅳ and other groups(P<0.05),while there was no significant difference between the other groups(P>0.05);There were significant differences in pH24h values among the groups,and compared with the control group,the group Ⅲ showed a significant dif-ference(P<0.05).(4)Compared with the control group,the IgG content in all experimental groups increased,with significant differences(P<0.05)observed in experimental groups Ⅰ,Ⅱ,and Ⅲ;The IgM content in groups Ⅰ,Ⅱ,and Ⅲ increased,but there was no significant difference(P>0.05),while group Ⅳ was lower than the control group;The C3 content in the experimental group increased,and there was a significant difference(P<0.05)between experimental groups Ⅱ and Ⅲ;The C4 content in each experimental group increased,but there was no significant difference compared to the thymus index,bursa index,and spleen index(P>0.05).Conclusion:Adding com-pound plant essential oils to the diet can improve production performance,slaughter performance,partial meat quality,and partial im-mune function;Based on comprehensive comparison,the appropriate dosage for adding compound plant essential oils is 300 mg/kg.关键词
