葵花籽对羊组织共轭亚油酸沉积及相关酶基因表达的影响
Effect of sunflower seed on conjugated linoleic acid accumulation and relative enzymes gene expression of sheep
摘要
Abstract
The objective of this research is to study the effects of dietary sunflower seed（SS） on conjugated linoleic acid（CLA）content,Stearoyl-CoA desaturase（SCD） and fatty acid synthase（FAS）gene expression in different tissues of growing sheep.Eighteen 3-month old male growing sheeps（（22.47 kg±0.62） kg） were randomly divided into two groups,where one group was fed basic dietary without SS（the Control Group） for 30 days,and the other group was fed experimental dietary with 6% SS（the Treatment Group） for 30 days.Results showed that supplementation of SS in dietary significantly increased the content of t11-C18：1,c9 and t11-CLA（P0.01） in blood,and it also increased the content of c9 and t11-CLA in subcutaneus adipose tissue.The content of c9 and t11-CLA in perinephrit fat and liver had a growing tendency,while the content of c9 and t11-CLA in Longissimus dorsi muscles had no significant change.SCD gene expression of treatment group in subcutaneous fat increased 2.88 times（P0.01）,but there is no significantly change in liver and perinephrit fat（P0.05）.FAS gene expression of the treatment group in liver and perinephrit fat decreased significantly（P0.05）,while no significant change was observed in subcutaneous fat（P0.05）.关键词
