摘要

本试验旨在研究发酵菜籽粕对28~49日龄白羽公番鸭生长性能及血清生化、激素和抗氧化指标的影响。菜籽粕经嗜酸乳杆菌、枯草芽孢杆菌和酿酒酵母混合菌发酵,制备发酵菜籽粕。选择同一批出雏且体重相近的28日龄白羽公番鸭240只,随机分成2组,每组6个重复,每重复20只。对照组和试验组分别饲喂含8%普通菜籽粕和8%发酵菜籽粕的基础饲粮,试验期21 d。结果表明:1)发酵可有效降低菜籽粕中硫甙和粗纤维含量,提高粗蛋白质和总氨基酸含量。2)试验组的终末体重、平均日采食量和平均日增重均显著高于对照组(P<0.05)。3)试验组的血清超氧化物歧化酶活性显著低于对照组(P<0.05),其他血清生化、激素和抗氧化指标与对照组均无显著差异(P>0.05)。由此可知,发酵可有效降低菜籽粕中硫甙含量,提高菜籽粕营养价值。用发酵菜籽粕替代饲粮中的普通菜籽粕,可提高番鸭的生长性能,而对血清生化和激素指标无显著影响。

Abstract

This experiment was conducted to study the effects of fermented rapeseed meal on growth performance and serum biochemical, hormone and antioxidant indexes of white male Muscovy ducks during 28 to 49 days of age. The rapeseed meal was fermented with Lactobacillus farciminis, Bacillus subtilis and Saccharomyces cerevisiate mixed culture, to prepare the fermented rapeseed meal. Two hundred and forty 28-day-old white male Muscovy ducks with same batch of hatching and similar body weight were randomly divided into 2 groups with 6 replicates in each group and 20 ducks in each replicate. Ducks in the control group were fed a basal diet containing 8% common rapeseed meal, and the others in the experimental group were fed the basal diet containing 8% fermented rapeseed meal. The experiment lasted for 21 days. The results were showed as follows:1) fermentation could effectively decreased the contents of glucosinolate and crude fiber in rapeseed meal, and increased the contents of crude protein and total amino acid. 2) The final body weight, average daily feed intake, average daily gain of experimental group were significantly higher than those of the control group (P<0.05). 3) The serum superoxide dismutase activity of experimental group was significantly lower than that of the control group (P<0.05), however, the other serum biochemical, hormone and antioxidant indexes of experimental group had no significant difference compared with the control group (P>0.05). In conclusion, fermentation can effectively reduce the glucosinolate content and improve the nutritional value of rapeseed meal. Replacement of common rapeseed meal by fermented rapeseed meal in diet can improve the growth performance of Muscovy ducks, but has no significant effects on serum biochemical and hormone indexes.
