通过为期8周的饲养试验，研究了枯草芽孢杆菌全植物蛋白饲料对牛蛙生长、营养物质消化率、肠道组织形态学和微生物组成的影响。总共制备了四种饮食：未补充的对照饮食和含有1 × 105，1 × 107或1 × 109 CFU g− 1 ofB的三种益生菌饮食。枯草芽孢杆菌（Con、BS 5、BS 7和BS 9饮食）。实验一式三份进行，平均42.5 ± 0.2 g的牛蛙每天两次喂食至视觉饱足。添加益生素对肉鸭的生长、饲料利用率、体成分和成活率无显著影响（P> 0.05）。然而，蛋白质，钙和磷的表观消化率系数显着改善益生菌补充。此外，全身磷和钙含量提高益生菌管理。BS 5组绒毛高度和厚度最高。施用1 × 107 CFU g-1 ofB显著提高了操作分类单位（OTU）的多样性和丰富度。枯草杆菌。此外，B.肠道中的枯草杆菌素随着益生菌内含物水平的增加而增强，表明益生菌的成功建立。本研究结果表明，补充1 × 107 CFU g− 1 ofB。牛蛙的枯草杆菌蛋白酶豆粕基饮食有益地影响营养物质的消化和吸收，以及肠道结构和微生物组成。
An 8-week feeding experiment was carried out to evaluate the supplemental effects ofBacillus subtilisin all-plant protein diets on growth, nutrients digestibility, and intestinal histomorphology and microbial composition in bullfrogLithobates catesbeianus. Totally four diets were prepared: a non-supplemented control diet and three probiotic diets containing 1 × 105, 1 × 107or 1 × 109CFU g−1ofB. subtilis(Con, BS5, BS7 and BS9 diets). The experiment was done in triplicates and bullfrogs averaging 42.5 ± 0.2 g were fed to visual satiety twice daily. No significant changes in growth, feed utilization, body composition and survival rate were found by probiotic application (P> 0.05). However, significant improvements in apparent digestibility coefficients of protein, calcium and phosphorus were found by probiotic supplementation. Moreover, whole-body phosphorous and calcium contents were enhanced by probiotic administration. The highest villus height and thickness were recorded in the BS5 group. Operational taxonomic unit (OTU) diversity and richness significantly increased by application of 1 × 107CFU g-1ofB. subtilis. Furthermore,B. subtilisabundance in the gut was enhanced with increasing the probiotic inclusion level indicating the successful establishment of the probiotic. The findings in this research showed that supplementing 1 × 107CFU g−1ofB. subtilisin soybean meal-based diets for bullfrog beneficially influences nutrients digestibility and uptake, and intestinal structure and microbial composition.
