紫苏醇对肉仔鸡生长性能、腹脂沉积、肝脏脂质代谢及屠宰性能的影响
Effects of perillol on growth performance,abdominal lipid deposition,liver lipid metabolism,and slaughter performance of broilers
摘要
Abstract
The purpose of this experiment was to study the effects of perillol on the growth performance,abdominal fat deposition,liver lipid metabolism,and slaughter performance of yellow feather broilers fed a high-fat diet.Forty-five 1-day-old broilers were randomly divided into three groups with three replicates in each group and five chickens in each replicate.The three groups were fed with basal diet,high-fat diet and high-fat diet supplemented with 1 g/kg perillol,respectively.The pre-test period was seven days,and the formal test period was 15 days.The results showed that compared with the high-fat diet group,the addition of perillol had no significant effect on the final weight,average daily gain,average daily feed intake,feed-to-weight ratio,and intestinal length of broilers(P＞0.05).The addition of perillol significantly reduced the abdominal fat rate of broilers(P＜0.05),and made the adipocytes smaller.The contentrations of triglyceride(TG)and cholesterol(TC)in liver decreased(P＜0.05),the content of high density lipoprotein cholesterol(HDL-C)in serum increased(P＜0.05),and the contentrations of TG,TC,and low density lipoprotein cholesterol(LDL-C)in serum decreased(P＜0.05).Perillol increased the relative expression of Pparα,Cptl,and Apoal genes related to liver lipid metabolism,decreased the relative expression of Apob gene(P＜0.05).The addition of perillol significantly increased the slaughter rate,chest muscle rate,and lean meat rate of broilers,and decreased the subcutaneous fat thickness and intermuscular fat width(P＜0.05).The results showed that perillol had no significant effect on the growth performance of broilers,but could reduce the fat deposition in the liver,serum and abdomen of broilers by regulating the expression of genes related to fatty acid β-oxidation and cholesterol transport,and improve the slaughter performance of broilers.关键词
