The microbiota structure in the cecum of laying hens contributes to dissimilar H₂S production.

ABSTRACT:

Background

Host genotype plays a crucial role in microbial composition of laying hens, which may lead to dissimilar odor gas production. The objective of this study was to investigate the relationship among layer breed, microbial structure and odor production.

Results

Thirty Hy-Line Gray and thirty Lohmann Pink laying hens were used in this study to determine the impact of cecal microbial structure on odor production of laying hens. The hens were managed under the same husbandry and dietary regimes. Results of in vivo experiments showed a lower hydrogen sulfide (H₂S) production from Hy-Line hens and a lower concentration of soluble sulfide (S^2-) but a higher concentration of butyrate in the cecal content of the Hy-Line hens compared to Lohmann Pink hens
