胆汁酸对天长三黄鸡育成期生长性能、血清生化指标及抗氧化能力的影响
Effects of bile acids on growth performance,serum biochemical indexes,and antioxidant capacity of Tianchang Sanhuang chickens during growing period
摘要
Abstract
The experiment aimed to investigate the effects of bile acids on the growth performance,serum biochemical indexes,and antioxidant capacity of Tianchang Sanhuang chickens during the growing period.A total of 300 seven-week-old Tianchang Sanhuang chickens with similar body condition were randomly divided into five groups,each group with six replicates,and each replicate consisted of 10 chickens.The basal diets were supplemented with 0(control group),0.01％chenodeoxycholic acid(CDCA),0.02％CDCA,0.01％hyodeoxycholic acid(HDCA),and 0.02％HDCA,respectively.The experiment lasted for eight weeks.The results showed that at the age of 7 to 10 weeks,compared with the control group,the 0.02％HDCA extremely reduced the content of HDL-C in the serum(P＜0.01),the 0.01％CDCA significantly reduced the content of CREA in the serum(P＜0.05),and the 0.02％CDCA significantly reduced the activity of T-SOD in the serum(P＜0.05).At the age of 11 to 14 weeks,compared with the control group,the 0.02％CDCA significantly increased the average daily weight gain(P＜0.05)and significantly reduced the feed to gain ratio(P＜0.05),the 0.01％CDCA and 0.01％HDCA group extremely increased the daily growth of tibial circumference(P＜0.01),the 0.02％HDCA extremely increased the activity of ALT in the serum(P＜0.01),and the 0.02％CDCA extremely reduced the activity of AST in the serum(P＜0.01),and the 0.01％CDCA and 0.01％HDCA significantly reduced the content of TBA in the serum(P＜0.05).The study indicates that the addition of bile acids to the feed can effectively improve the growth performance of Tianchang Sanhuang chickens during the growing period,improve some serum biochemical indexes,and does not affect the body's antioxidant enzyme activity,with the addition of 0.02％CDCA showing the better effect.关键词
