Sodium butyrate reduces ammonia production in the cecum of laying hens by regulating ammonia-producing bacteria.

ABSTRACT: Sodium butyrate is a commonly used feed additive and can reduce ammonia (NH₃) emissions from laying hens, but the mechanism of this effect is unknown. In this study, the sodium butyrate and cecal content of Lohmann pink laying hens were measured, and in vitro fermentation experiments and NH₃-producing bacteria coculture experiments were carried out to explore the relationship between NH₃ emissions and its associated microbiota metabolism. Sodium butyrate was found to significantly reduce NH₃ emission from the cecal microbial fermentation of Lohmann pink laying hens (P < 0.05). The concentration of NO₃^--N in the fermentation broth of the sodium butyrate-supplemented group increased significantly, and the concentration of NH
