Anaerobutyricum and Subdoligranulum Are Differentially Enriched in Broilers with Disparate Weight Gains

The intestinal microbiota is critically important for animal health and productivity. However, the influence of on growth efficiency remains elusive. This current study was aimed at identifying bacteria that are associated with rate broilers in a commercial production setting. Ross 708 extremely high, medium, low body weight (BW) were separately selected each sex from house approximately 18,000 chickens day 42. cecal content subjected to 16S rRNA gene sequencing profiling. Our results indicate number differentially enriched among different groups broilers, several showing significant correlation (p < 0.05) BW both sexes or sex-specific manner. Subdoligranulum drastically diminished high-BW birds strong negative males females. While one Anaerobutyricum strain showed positive sexes, another positively correlated only These sex-dependent -independent could be targeted improving may also explored as potential biomarkers broiler chickens.
