摘要：
Based on repeatedly reported extensive pantothenic acid disappearance in the rumen, the present study is aimed at examining if pantothenic acid is used for a more efficient ruminal fermentation and microbial growth in an artificial rumen (Rusitec). Three substrates differing in roughage/concentrate ratio were incubated with and without the addition of Ca-D-pantothenate. Pantothenic acid was extensively degraded without notably influencing fermentation, microbial protein synthesis and the status of other B-vitamins such as riboflavin, vitamin B-6 and niacin. Therefore, pantothenic acid supplementation cannot be expected to contribute to microbial benefit for the ruminant animal.
