Fig. 1From: The microbiota structure in the cecum of laying hens contributes to dissimilar H2S productionThe production of H2S and NH3 at different times and on the whole day. a The production of H2S every 2 h, each value is a mean for 3 days (6 replicates). b Cumulative daily H2S production per kg average daily feed intake of chickens (ADFI). c The production of NH3 every 2 h, each value is a mean for 3 days (6 replicates). d Cumulative daily NH3 production per kg ADFI. Error bars show one standard deviation and the mean value was labeled above the error bars with different superscripts mean significant difference (P < 0.05).
