摘要

目的:研究混合多种微生物的发酵米糠提取物(FRB)对保育猪肠道健康和生长性能的影响。方法:采用完全随机区组设计,将30头初始体重为6.8±0.8 kg的断奶仔猪分为3个饲粮处理(每个处理n = 10),分2期(分别为7天和18 d)饲喂25 d。猪被单独饲养在配有喂食器和奶嘴吸奶器的围栏里。饲喂在基础饲粮中添加0%、0.5%和1.0% FRB的试验猪。基础日粮的主要饲料为玉米、豆粕、乳清膜和血浆。以植物乳杆菌、枯草芽孢杆菌和酿酒酵母菌为原料,对米糠进行发酵制备的FRB,其含量至少为1×107 CFU/g。第25天对猪实施安乐死,收集肠道组织和黏膜,以保持肠道健康。结论:饲粮中添加多种微生物种类的FRB可从免疫反应、氧化应激和肠道形态等方面改善肠道健康。苗猪的生长性能随FRB添加量的增加呈二次响应关系。其中,添加0.48%的FRB时G:F最大。

Effects of fermented rice bran extract with multi-microbial species on intestinal health and growth of nursery pigs.

Objective: The objective of this study was to investigate the effects of fermented rice bran extract (FRB) with multi-microbial species on intestinal health and growth performance of nursery pigs.

Methods: Thirty weaned pigs (initial body weight = 6.8±0.8 kg) were allocated to 3 dietary treatments in a randomized complete block design (n = 10 per treatment) and fed for 25 d in 2 phases (7 and 18 d, respectively). Pigs were housed individually in pens equipped with a feeder and a nipple drinker. Pigs were fed a basal diet supplemented with 0%, 0.5%, or 1.0% FRB. The main feedstuffs of the basal diet were corn, soybean meal, whey permeate, and blood plasma. The FRB was prepared by fermenting rice bran with Lactobacillus plantarum, Bacillus subtilis, and Saccharomyces cerevisiae, and contained at least 1×107 CFU/g. On d 25, pigs were euthanized to collect intestinal tissues and mucosa for intestinal health.

Results: The supplementation of FRB decreased (p<0.05) the abundance of Desulfovibrio piger in the jejunal mucosa. Malondialdehyde and protein carbonyl in the duodenum linearly decreased (p<0.05) and the villus height to crypt depth ratio in the jejunum linearly increased (p<0.05) with increasing FRB supplementation. The apparent ileal digestibility of gross energy and crude protein tended to linearly increase (p=0.084 and p=0.098, respectively). Body weight on d 25 and overall average daily gain tended to show quadratic responses (p=0.084 and p=0.095, respectively) with increasing FRB supplementation. The gain to feed ratio (G:F) was maximized when the FRB intake was 2.7 g/d (0.48%) during d 7 to 25.

Conclusion: Dietary supplementation with FRB with multi-microbial species improved intestinal health based on immune response, oxidative stress, and morphology. The growth performance of nursery pigs showed quadratic responses with increasing FRB supplementation. Specifically, the G:F was maximized with supplementation of FRB at 0.48%.
