Effects of calcium level and source, formic acid, and phytase on phytate degradation and the microbiota in the digestive tract of broiler chickens.

ABSTRACT:

Background

Diet acidification, dietary calcium (Ca) level, and phytase supplementation are known influences on the microbial community in the digestive tract and on phosphorus (P) utilization of broiler chickens. Effects of dietary factors and microbiota on P utilization may be linked because microorganisms produce enzymes that release P from phytate (InsP₆), the main source of P in plant feedstuffs. This study aimed to detect linkages between microbiota and InsP₆ degradation by acidifying diets (i.e., replacing Ca carbonate (CaCO₃) by Ca formate or adding formic acid to CaCO₃-containing diets), varying Ca levels, and supplementing phytase in a three-factorial design. We investigated i) the microbial community and pH in the digestive trac
