摘要

本试验旨在研究饲粮中添加50~200 mg/kg假蒟提取物对断奶仔猪生长性能、血液指标的影响。选取21日龄断奶仔猪80头,随机分为4个组(T0组、T50组、T100组、T200组),每组5个重复,每重复4头,分别在饲粮中添加0、50、100、200 mg/kg假蒟提取物,试验正试期28 d。结果表明:与对照组相比,在饲粮中添加50 mg/kg假蒟提取物能提高断奶仔猪第1~28天和第15~28天的平均日采食量(ADFI)和平均日增重(ADG)(P<0.05);假蒟提取物能增加血液中血小板数(PLT),显著提高断奶仔猪第29天血清中总蛋白(TP)含量和第15、19天血清球蛋白(GLB)、免疫球蛋白(Ig)G、IgA、IgM含量(P<0.05),同时降低血清中谷丙转氨酶(ALT)、谷草转氨酶(AST)活性和胆固醇(CHOL)、尿素氮(UN)含量。本试验表明,在饲粮中添加50 mg/kg假蒟提取物能提高断奶仔猪平均日采食量;假蒟提取物能提高断奶仔猪的免疫力,改善肝脏功能,促进蛋白质的合成和代谢。

Abstract

This study was conducted to investigate the effects of Piper sarmentosum extracts (PSE) on the growth performance and blood indexes of weaned piglets.Eighty 21-day-old weaned piglets were selected and randomly allocated into four groups with five replicates per group and 4 piglets per replicate.Piglets were fed a basal diet supplemented with PSE at 0, 50, 100 and 200 mg/kg for 28 days.The results showed as follows: compared with control group, average daily gain (ADG) and average daily feed intake (ADFI) from day 1 to day 28 and day 15 to day 28 of piglets fed the diet supplemented with PSE at 50 mg/kg were significantly increased (P<0.05).PSE could increase the number of platelets (PLT) in the blood and significantly increase the serum contents of total protein (TP), globulin (GLB), immunoglobulin (Ig)G, IgA, IgM (P<0.05).Meanwhile, dietary PSE supplementation reduced the serum activity of alanine aminotransferase (ALT) and aspartate transaminase (AST), and contents of cholesterin (CHOL) and urea nitrogen (UN) of piglets.The conclusion shows that dietary PSE supplementation with 50 mg/kg can improve the ADFI of weaned piglets, while dietary PSE supplementation can improve immune function, liver function, and promote protein synthesis and metabolism of weaned piglets.
