摘要:

本试验旨在研究小刺猴头发酵多糖(HFP)对肉鸡血清、肌肉、肝脏、心脏、肌胃、粪便中胆固醇含量的影响。试验选用1日龄AA肉鸡240只,随机分为4个处理,每个处理3个重复,每个重复20只,分别饲喂含HFP00.1%0.3%0.5%的饲粮,试验时间为42 d。结果表明,在不同日龄阶段(142842日龄),与对照组相比,饲粮中添加0.3%0.5%水平的HFP可显著降低肉鸡血液中总胆固醇和低密度脂蛋白胆固醇的含量(P0.05),显著增加血液中高密度脂蛋白胆固醇含量(P0.05);0.3%0.5%水平HFP 添加组肉鸡的胸肌、腿肌和肝脏中胆固醇含量均显著低于对照组(P0.05),0.5%水平HFP 添加组肉鸡肌胃中胆固醇含量显著低于对照组(P0.05),饲粮中添加HFP对肉鸡心脏胆固醇水平没有显著影响(P0.05);与对照组相比,饲粮中添加不同水平的HFP能够显著增加肉鸡粪便中胆汁酸的排泄(P0.05),0.3%0.5%水平的HFP添加组肉鸡粪便中胆固醇含量也显著高于对照组(P0.05)。结果提示,肉鸡饲粮中添加HFP可能通过增加肉鸡粪便中胆固醇和胆汁酸的排泄,从而降低肉鸡肌肉、肝脏、肌胃中胆固醇的含量。

Abstract:

This experiment was conducted to study the effects of dietary polysaccharides from the submerged fermentation extract of Hericium caput-medusae (Bull.:Fr.) Pers. (HFP) on the contents of cholesterol in serum, muscles, liver, heart, muscular stomach, excreta of broilers. A total of 240 one-day-old AA broilers were divided randomly into 4 groups with 3 replicates of 20 broilers each, and fed diets containing four concentrations of HFP (0, 0.1%, 0.3% and 0.5%) during the 42 days study. The results showed that, compared with control group, at different age stages (day 14, 28 and 42), dietary supplementation of HFP at the levels of 0.3% and 0.5% significantly decreased serum total cholesterol and low density lipoprotein cholesterol contents(P0.05), and significantly increased serum high density lipoprotein cholesterol content of broilers compared to the control group(P0.05). Cholesterol levels of breast muscle, thigh muscle and liver were significantly reduced in the broilers fed with 0.3% and 0.5% of HFP than those in control group (P0.05), and cholesterol content of muscular stomach was lower in the broilers fed with 0.5% of HFP compared to control group(P0.05). Dietary supplementation of HFP had no significantly effect on cholesterol content of broilers heart (P0.05). Compared with the control group, supplementation with HFP at different levels significantly increased bile acid excretion in feces of broilers(P0.05), and cholesterol contents of excreta were also higher in the broilers fed with 0.3% and 0.5% of HFP compared to the control group(P0.05). The results of this study suggest that the decreased contents of cholesterol in muscles, liver and muscular stomach of broilers may be caused by an increase in the fecal excretion of cholesterol and bile acid.
