复合植物提取物替代饲用抗生素对断奶仔猪生长性能和血清指标的影响
Effects of Composite Plant Extracts Replacing Feed Antibiotics on Growth Performance and Serum Indexes of Weaned Piglets
摘要
Abstract
This study was conducted to investigate the effects of composite plant extracts(CPE)(from grana-tum, argy wormwood leaf, Kadsura japonica L. and Fructus evodiae rutaecarpae)replacing feed antibiotics on growth performance and serum indexes of weaned piglets. In experiment 1, a total of 160 weaned piglets weighted about 8 kg at about 30 days of age were selected and randomly allocated into 4 groups with 4 repli-cates per group and 4 piglets per replicate. Piglets in different groups were fed a basal diet supplemented with aureomycin 107 mg/kg+flavomycin 40 mg/kg(control)and CPE at 0.05%,0.10% and 0.20% for 28 d,re-spectively. In experiment 2, a total of 120 weaned piglets weighted about 11 kg at about 40 days of age were selected and randomly allocated into 3 groups. Piglets in antibiotic-free group were fed the basal diet,and those in the other two groups were fed the basal diet supplemented with aureomycin 67 mg/kg+flavomycin 20 mg/kg (antibiotics group)and CPE at 0.10% for 35 d, respectively. The results of experiment 1 showed as follows:compared with control group, average daily gain(ADG), average daily feed intake(ADFI)and feed/gain (F/G)of CPE groups were not significantly changed(P>0.05), and 0.10% CPE group had better ADG, which was 2.44% higher than control group(P>0.05). The results of experiment 2 showed as follows: com-pared with antibiotic-free group, in 0.10% CPE group, ADG was significantly increased by 21.39%(P<0.05), the contents of serum albumin(ALB), cholesterol(CHOL), low density lipoprotein-cholesterol (LDL-C)and nitric oxide(NO)were significantly decreased(P<0.05), serum glutathione peroxidase (GSH-Px)activity was significantly increased(P<0.05), and serum ceruloplasmin(CER)activity was sig-nificantly decreased(P<0.05);compared with antibiotic group,in 0.10% CPE group,ADG was significantly increased by 15.07%(P<0.05),the contents of serum urea nitrogen(UN),LDL-C and NO were significant-ly decreased(P < 0. 05). Collectively, CPE supplementation at 0. 10% can replace feed antibiotics (aureomycin+flavomycin), improve growth performance, and has anti-stress and anti-oxidation functions in weaned piglets.关键词
