Effects of Chinese medicinal herbs additives on growth performance,antioxidant capacity,and immune function of growing chickens
摘要
Abstract
The experiment aimed to investigate the effects of Chinese medicinal herbs additives on the growth performance and immune function of growing chickens.A total of 288 healthy Jinghong No.1 growing chickens at six weeks of age were randomly divided into four groups,with six replicates in each group and 12 chickens in each replicate.Group Ⅰ(Control group),Group Ⅱ,Group Ⅲ,and Group Ⅳ were supplemented with 0,0.5％,1.0％,and 1.5％Chinese medicinal herbs additives in the basic diet,respectively.The experimental period lasted for eight weeks.The results showed that compared to Group Ⅰ,the body weight of experimental groups at 10 and 14 weeks of age was significantly increased(P＜0.05),the average daily weight gain in Group Ⅱ,Group Ⅲ,and Group Ⅳ was increased at 7 to 10 weeks and 11 to 14 weeks of age.At 14 weeks of age,the serum growth hormone level in Group Ⅳ was significantly higher than that of Group Ⅰ(P＜0.05),the serum thyroxine levels in Group Ⅱ,Group Ⅲ,and Group Ⅳ were significantly higher than that of Group Ⅰ(P＜0.05).At 10 weeks of age,the serum T-AOC,SOD,and GSH-Px activities were enhanced,and the serum MDA content was reduced in Group Ⅱ,Group Ⅲ,and Group Ⅳ.At 14 weeks of age,the serum CAT activity was significantly increased in Group Ⅱ and Group Ⅳ,and the serum MDA content was significantly reduced in Group Ⅱ and Group Ⅲ(P＜0.05).Compared to Group Ⅰ,the serum IL-6 content was significantly reduced,and the IL-10 content was significantly increased in Group Ⅲ at 10 weeks of age(P＜0.05).At 14 weeks of age,the serum IL-6 and IL-1β contents were significantly reduced in Group Ⅳ(P＜0.05),the serum IL-10 content was significantly increased in Group Ⅱ,Group Ⅲ,and Group Ⅳ(P＜0.05).The study indicates that the addition of Chinese medicinal herbs to the diet can improve the growth performance,enhance immune function,and antioxidant capacity of growing chickens,with the suitable addition rate being 0.5％.关键词
