艾蒿粉对肉仔鸡生长性能、屠宰性能和肉品质的影响

Effects of Artemisia argyi powders on growth performance,slaughter performance and meat quality in broilers

试验探讨艾蒿粉对肉仔鸡生长性能、屠宰性能和肉品质的影响。试验选择1日龄AA肉仔鸡240只,按照艾蒿粉添加量的不同(0、0.25%、0.50%、1.00%和2.00%)分为5个不同处理组,每个处理组6个重复,每个重复8只鸡,试验期共42d,分为前、后两期,每期21d。结果表明:随着艾蒿粉添加量的增加,肉仔鸡后期与全期的平均日增重呈显著的先升高后降低的变化趋势,以0.25%组最高;肉色亮度L*值呈显著的下降趋势,肉色红度a*值呈显著的上升趋势;屠宰性能的各项指标差异均不显著。肉仔鸡日粮中添加适量的艾蒿粉对其生长性能有促进作用,对肉品质有改善作用。

The present experiments were conducted to investigate the effects of dietary A rtemisia argyi powders on growth performance ,slaughter performance and meat quality in broilers .A total of 240 one-day-old Arbor Acres （AA） broilers were selected and assigned randomly into 5 treatments（0 ,0 .25% ,0 .50% ,1 .00% and 2 .00% A rtemisia argyi powders level in diet-ary） with 6 replicates （8 broilers per replicate） .The feeding trial lasted for 42 d and was divided into two periods （1-21 d and 22-42 d） .The results showed that ：diets supplemented with A rtemisia argyi powders increasing ,ADG of broilers during 22-42 d and 1-42 d increased at first and then decreased ,that of 0 .25% group was the highest ;color brightness values（ L^＊ ） were significantly decreased and degree of red values（a^＊ ） showed a significant upward trend;the differences of slaughter per-formance indicators were not significant .Overall ,the present study indicated that appropriate amount of A rtemisia argyi pow-ders could improve the growth performance and meat quality of broilers to some extent .
