饲喂青贮桑叶对陕北白绒山羊PPARγ、ADIPOQ、aP2mRNA表达的影响
Effects of Diets Supplemented with Ensiled Mulberry Leaves on Expression of PPARγ,ADIPOQ, aP2 mRNA on Shanbei White Cashmere Goats
摘要
Abstract
This experiment was conducted to study the effects of diets supplemented with ensiled mulberry leaves on the mRNA expression of Peroxisome proliferator-activated receptor-γ (PPARγ),Adiponectin (ADIPOQ),adipocyte fatty acid-binding protein (aP2) in the adipose tissues (subcutaneous,tail,perirenal),liver and muscle of Shaanbei white cashmere goats.Forty Shaanbei white cashmere goats were selected and randomly divided into 4 groups.Control group was fed the basal diet (group Ⅰ);The experimental one was the basal diet supplemented with 10 ％ (group Ⅱ),15 ％ (group Ⅲ),20％ (group V)of ensiled mulberry leaves (dry matter basis) with pre-feeding period of 10 d,the formal period of 60 d,the trial period 70 d.At the end of experience,it respectively and randomly selects three goats from each group to slaughter trial and collects samples for required determination indicator.The results are as follows:PPARγ,ADIPOQ,aP2 mRNA expressed in all tissues studied.PPARγ mRNA highly expressed in subcutaneous adipose tissue than other tissues (P＜0.05),the same as aP2.ADIPOQ mRNA highly expressed in adipose tissues than in the liver and muscle (P＜0.05).In subcutaneous adipose tissue and liver,PPARγ,ADIPOQ,aP2 mRNA highly expressed in group Ⅰ than other groups (P＜0.05).In other tissues,different levels of diets supplemented with ensiled mulberry leaves have different effects on expression of PPARγ,ADIPOQ,aP2 mRNA on Shaanbei White cashmere goats.Theses results suggest that the effects of diets supplemented with ensiled mulberry on PPAR-γ,ADIPOQ,aP2 mRNA expression were significant,ensiled mulberry leaves can be used as a potential fat-decreasing diet to adjust fat accumulation and improve meat quality for goats.关键词
