【摘要】：本试验旨在研究益生菌发酵苹果渣对断奶仔猪表观消化率、血清免疫指标和肠道菌群与形态的影响。选择平均体重为5.87 kg的断奶仔猪120头,随机分为5组(每组设3个重复,每个重复8头仔猪),其中负对照组(NC)饲喂基础饲粮(不含抗生素),正对照组(PC)在基础饲粮中添加0.1%的混合型抗生素,试验组(AP)分别在基础饲粮中添加4%、6%、8%益生菌发酵苹果渣。试验期35 d。结果表明:与NC组相比,6%的益生菌发酵苹果渣显著提高粗蛋白和粗脂肪的表观消化率(P0.05),提高前期血清中免疫球蛋白A(Ig A)、免疫球蛋白G(Ig G)、白细胞介素6(IL-6)的含量和后期血清中Ig A的含量(P0.05),但对后期血清中Ig G、白细胞介素4(IL-4)和IL-6均无显著影响(P0.05);与NC组相比,6%的益生菌发酵苹果渣显著降低肠道大肠杆菌数量(P0.05),提高十二指肠和盲肠中乳酸杆菌和芽孢杆菌的数量(P0.05);6%的益生菌发酵苹果渣显著提高小肠绒毛高度,降低十二指肠和空肠的隐窝深度,增大十二指肠和空肠的绒毛高度/隐窝深度(P0.05);随着益生菌发酵苹果渣添加量的增加,粗蛋白和粗脂肪的表观消化率、大肠杆菌、Ig A、小肠绒毛高度和十二指肠与空肠的隐窝深度均呈现二次变化趋势(P0.05)。由此可见,添加6%益生菌发酵苹果渣能够提高断奶仔猪的表观消化率和免疫力;调节肠道微生态平衡,改善肠道内环境。
[Abstract]:The purpose of this experiment was to study the effects of probiotic fermented apple dregs on apparent digestibility, serum immune index, intestinal flora and morphology of weaned piglets. 120 weaned piglets with an average body weight of 5.87 kg were randomly divided into 5 groups (3 replicates in each group). The negative control group (NC) was fed with basal diet (excluding antibiotics), the positive control group (PC) added 0.1% mixed antibiotics to the basal diet, and the experimental group (AP) added 4 (6%) probiotic fermented apple dregs to the basal diet. The trial period was 35 days. The results showed that the apparent digestibility of crude protein and crude fat was significantly increased by 6% probiotic fermented apple dregs compared with NC group (P0.05), and the content of IgG A), immunoglobulin G (IgG) and interleukin-6 (IL-6) in serum were increased in the early stage and later. Compared with NC group, 6% of apple pomace of probiotics significantly decreased the number of intestinal Escherichia coli (P0.05), increased duodenum and blindness (P0.05), but had no significant effect on the levels of IgG, IL-4 and IL-6 in serum of later stage (P0.05), compared with NC group, 6% of apple pomace from probiotic fermentation significantly decreased the number of Escherichia coli in intestinal tract (P0.05). The number of Lactobacillus and Bacillus in intestine (P0.05) increased the height of villi of small intestine by fermentation apple dregs with 6% probiotics. Decrease the depth of crypt of duodenum and jejunum, increase the height of villi / depth of crypt in duodenum and jejunum (P0.05), and increase the apparent digestibility of crude protein and crude fat with the increase of the amount of apple dregs fermented by probiotics. E. coli Ig A, villi height of small intestine and recess depth of duodenum and jejunum showed a second change trend (P0.05). It can be seen that the addition of 6% probiotic fermented apple dregs can improve the apparent digestibility and immunity of weaned piglets, regulate the intestinal microecological balance and improve the intestinal environment.
