摘 要:試驗旨在研究發(fā)酵豆粕代替海蘭褐蛋雞飼糧中的豆粕對海蘭褐蛋雞生產(chǎn)性能、蛋品質(zhì)
和免疫功能的影響。試驗選取144只48周齡體型和產(chǎn)蛋率基本一致的海蘭褐蛋雞,隨機分為2組,每
組 6 個重復(fù),每個重復(fù) 12 只雞。對照組飼喂基礎(chǔ)飼糧,試驗組用發(fā)酵豆粕替代 40% 豆粕。試驗期
8 周。結(jié)果表明:①與對照組相比,發(fā)酵豆粕代替飼糧中 40% 豆粕可顯著提高海蘭褐蛋雞第 1~4 周
的合格蛋率(P<0.05),對平均日采食量產(chǎn)蛋率和第 5~8周的合格蛋率有提升的趨勢(0.05≤P<0.10)。
②與對照組相比,發(fā)酵豆粕代替飼糧中40%豆粕對海蘭褐蛋雞第4周的蛋黃顏色和哈氏單位有降低
的趨勢(0.05≤P<0.10)。③與對照組相比,用發(fā)酵豆粕代替飼糧中40%豆粕顯著提高了海蘭褐蛋雞第
4周和第8周免疫球蛋白A(IgA)水平(P<0.05),降低了第4周血清內(nèi)毒素(ET)水平(P<0.05),同時血
清白細胞介素-1β(IL-1β)有降低趨勢(0.05≤P<0.10)。綜上所述,在本試驗條件下,用發(fā)酵豆粕代替
飼糧中40%豆粕可提高海蘭褐蛋雞合格蛋率和采食量,降低IL-1β因子和ET水平,提高海蘭褐蛋雞
IgA水平,從而增強了機體免疫力和抵抗力。

Abstract:The experiment aimed to investigate the effects of fermented soybean meal on the production
performance, egg quality and immune function of Hy-line brown laying hens by replacing soybean meal
in the diet of Hy-line brown laying hens. A total of 144 Hy-line brown laying hens of 48 weeks of age
with essentially the same body size and egg production rate were selected and randomly divided into two
groups with six replicates of 12 hens in each group. The control group was fed the basal diet and the ex?
perimental group was fed fermented soybean meal instead of 40% of normal soybean meal. The trial pe?
riod was 8 weeks. The results showed that: ① compared with the control group, fermented soybean meal
replacing 40% soybean meal in the diet significantly increased the qualified egg rate of Hy-line brown
hens in weeks 1-4 (P<0.05), and had a tendency to improve egg production rate, average daily feed in?
take and qualified egg rate in weeks 5-8 (0.05≤P<
0.10). ② Compared with the control group, fer?
mented soybean meal replacing 40% soybean
meal in the ration had a tendency to reduce yolk
color and Hutchinson units in Hy-line Brown
hens at week 4 (0.05≤P<0.10). ③ Compared with
the control group, replacing 40% soybean meal in
the diet with fermented soybean meal significantly
