摘要:

旨在研究氨基葡萄糖(GlcN)对断奶仔猪生长性能、抗氧化能力及免疫功能的影响。选取250头体重相近的21日龄健康“杜×长×大”断奶仔猪,随机分为5个处理组,每组5个重复,试验期35 d。分别饲喂基础日粮(NC组)、基础日粮+金霉素75 mg·kg-1(PC组)、基础日粮+ GlcN 1 g·kg-1(G1组)、基础日粮+ GlcN 2 g·kg-1(G2组)和基础日粮+ GlcN 3 g·kg-1(G3组)。结果表明:1)与NC组相比,其余各组第15~35天和第1~35天ADFI与ADG显著提高,G1、G2和G3组第1~35天腹泻率显著降低(P < 0.05)。2)与NC组相比,第14天,其余各组血清MDA水平显著降低,G1、G2和G3组血清CAT活力显著提高(P < 0.05);G2组血清IL-1β水平和G1组血清TNF-α水平显著降低(P < 0.05)。第35天,其余各组血清MDA水平显著降低,血清CAT活力显著提高,G2和G3组血清T-AOC显著提高(P < 0.05);G1组血清IL-10水平显著提高、PC组和G1组血清IL-1β水平显著降低(P < 0.05)。3)与NC组相比,第35天,PC、G1和G3组血清A/G显著提高、其余各组血清AST水平显著降低(P < 0.05)。综上所述,GlcN能够提高断奶仔猪的生长性能、降低腹泻率,增强抗氧化能力和免疫功能,添加剂量以1 g·kg-1为宜,其使用效果优于75 mg·kg-1的金霉素。

Abstract:

This study aimed to investigate the effects of glucosamine (GlcN) on the growth performance, antioxidant capacity and immune function of weaned piglets. Two hundred and fifty 21-day-old healthy Duroc×Landrance×Yorkshire weaned piglets of similar weight were selected and randomly divided into 5 treatment groups with 5 replicates in each group. The basal diet (NC group), the basal diet+chlortetracycline 75 g·kg-1 (PC group), the basal diet+GlcN 1 g·kg-1 (G1 group), the basal diet+GlcN 2 g·kg-1 (G2 group) and the basal diet+GlcN 3 g·kg-1 (G3 group) were fed respectively for 35 days. The results showed that: 1) Compared with the NC group, the ADFI and ADG of day 15 to 35 and day 1 to 35 of the other four groups were increased significantly, and the diarrhea rate of day 1 to 35 in G1, G2 and G3 groups were decreased significantly (P < 0.05). 2) Compared with the NC group, the serum MDA levels of the other four groups were significantly reduced, the serum CAT activity in the G1, G2 and G3 groups were significantly increased (P < 0.05); the serum IL-1β levels of the G2 group and the serum TNF-α levels of the G1 group were significantly reduced (P < 0.05) at day 14. The serum MDA levels were significantly decreased and the serum CAT activity were significantly increased in the other four groups, and the serum T-AOC in the G2 and G3 groups were significantly increased (P < 0.05); the serum IL-10 levels in the G1 group was significantly increased, and the serum IL-1β levels in the PC group and the G1 group were significantly reduced (P < 0.05) at day 35. 3) Compared with the NC group, the serum A/G in the PC, G1 and G3 groups were significantly increased, and the serum AST levels in the other four groups were decreased significantly (P < 0.05) at day 35. In summary, GlcN can improve the growth performance, reduce diarrhea rate, enhance antioxidant capacity, and immune function in weaned piglets. The appropriate dosage of GlcN is 1 g·kg-1, and its effect is better than 75 mg·kg-1 chlortetracycline.
