摘要:

试验旨在研究补喂复合益生菌对3~6月龄伊犁马粪便纤维含量、VFA浓度和血浆细胞因子水平的影响。选取体重相近(90.23 kg±11.02 kg)、健康状况良好的3月龄伊犁马哺乳马驹10匹,随机分为2组,每组5匹,分别为对照组和试验组。在分阶段补喂等量营养水平的精料补充料和苜蓿干草的基础上,试验组每匹马驹每天补喂0.075 g(2×1011 CFU/g)枯草芽孢杆菌和0.133 g(3×1010 CFU/g)植物乳杆菌复合菌,进行为期90 d的饲养试验。结果显示,补喂复合益生菌能够显著或极显著降低马驹粪便中酸性洗涤纤维(ADF)和淀粉的含量(P < 0.05;P < 0.01),分别比对照组低3.50%和11.32%;显著或极显著提高马驹粪便中乙酸和丙酸的浓度(P < 0.05;P < 0.01),分别比对照组高14.65%和64.29%;极显著提高血浆中肿瘤坏死因子α(TNF-α)的水平(P < 0.01),比对照组高16.17%。由此可见,补喂复合益生菌能够降低马驹粪便中纤维的含量、提高挥发性脂肪酸(VFA)的浓度,增加3~6月龄伊犁马血浆细胞因子水平。

Abstract:

This study was aimed to examine the effects of supplemental feeding compound probiotics on feces fiber content,VFA concentration and plasma cytokines levels of 3-6 months old Yili horse.Ten Yili horses of 3 months old with the average body weight (90.23±11.02)kg were divided into 2 groups (control and trial groups),5 horses per group.The trial group was fed the basal diet supplemented with 0.075 g/d(2×1011 CFU/g) Bacillus subtilis and 0.133 g/d(3×1010 CFU/g).Lactobacillus plantarum.Feeding trial lasted for 90 d.The results showed that the contents of ADF and strach of feces in trial group were significantly or extremely significantly lower than that of control group(P < 0.05;P < 0.01),which were reduced by 3.50% and 11.32%,respectively.The acetic acid and propionic acid levels of feces in trial group were significantly or extremely significantly higher than that of control group (P < 0.05;P < 0.01),which were increased by 14.65% and 64.29%,respectively.The TNF-α level of plasma in trial group was extremely significantly higher than that of control group (P < 0.01),which was increased by 16.17%.This results indicated that supplementation of compound probiotics could reduce the fiber content of feces,increase the concentration of VFA and the plasma cytokine levels of 3-6 months old Yili horse.
