摘要

本试验旨在研究固态发酵醋糟饲料（SFVD）对育肥猪生长性能、养分表观消化率、血清指标及粪便中挥发性脂肪酸（VFA）含量的影响。选择体况相近[（59.04±0.33）kg]的健康"杜×长×大"三元杂交生长育肥猪60头，随机分为2个组，每组3个重复，每个重复10头猪。对照组饲喂基础饲粮+150 mg/kg土霉素钙，试验组饲喂基础饲粮+5%的SFVD。预试期6 d，正试期35 d。结果表明：与对照组相比，基础饲粮中添加5%的SFVD对育肥猪平均日采食量（ADFI）具有一定的促进趋势（P=0.056）；显著降低了育肥猪饲粮中干物质（DM）、粗蛋白质（CP）、有机物（OM）和总能（GE）的表观消化率（P<0.05），对粗脂肪（EE）表观消化率有一定的促进趋势（P=0.052）；显著提高了育肥猪血清谷草转氨酶（AST）和谷胱甘肽过氧化物酶（GSH-Px）活性（P<0.05），血清高密度脂蛋白（HDL）和免疫球蛋白A（IgA）含量也呈现出一定的升高趋势（P=0.055和P=0.077）；显著提高了育肥猪粪便中丙酸含量（P<0.05），粪便中甲酸和总挥发性脂肪酸（TVFA）含量也呈现出一定的升高趋势（P=0.071和P=0.054）。由此可见，基础饲粮中添加5%的SFVD对育肥猪生长性能、肠道健康及免疫性能的提高具有潜在的促进作用。

Abstract

This experiment was conducted to investigate the effects solid-state fermentation vinegar dregs (SFVD) on growth performance, nutrient apparent digestibilities, serum indexes and faecal volatile fatty acids content of finishing pigs. Sixty healthy "Duroc×Landrace×Yorkshire" finishing pigs with similar body condition[(59.04±0.33) kg] were randomly divided into 2 groups with 3 replicates per group and 10 pigs per replicate. Pigs in the control group were fed the basal diet+150 mg/kg oxytetracycline calcium, and the others in the experimental group were fed the basal diet+5% SFVD. The pre-experimental period lasted for 6 days, and the experimental period lasted for 35 days. The results showed that compared with the control group, the basal diet supplemented with 5% SFVD had a tendency of promotion on the average daily feed intake (ADFI) of finishing pigs (P=0.056); significantly decreased the apparent digestibilities of dry matter (DM), crude protein (CP), organic matter(OM) and gross energy (GE) of finishing pigs (P<0.05), and had a tendency of promotion on the ether extract apparent digestibility (P=0.052); significantly increased the activities of aspartate aminotransferase (AST) and glutathione peroxidase (GSH-Px) in serum of finishing pigs (P<0.05), and the contents of high density lipoprotein (HDL) and immunoglobulin A (IgA) in serum were showed an increasing trend (P=0.055 and P=0.077); significantly increased the faecal propionic acid content of finishing pigs (P<0.05), and the contents of formic acid and total volatile fatty acid (TVFA) in faeces were showed an increasing trend (P=0.071 and P=0.054). In conclusion, the basal diet supplemented with 5% SFVD has potential promoting effects on growth performance, intestinal health and immunity of finishing pigs.

Key words： finishing pigs; solid-state fermentation vinegar dregs; nutrient apparent digestibility; serum biochemical; immune; antioxidant; VFA
