The transmission of the fecal microbial ecosystem from the hen to   the surface of the egg, and evaluation of the influence of the birds feeding and housing system on this transmission

 

In poultry farming, both in broiler and in eggs productions, microbial populations on the surface of the eggshell after oviposition are still poorly known but may have an impact on the chick (future chicken or laying hen). I am interested in the transmission to its surface of the first bacteria encountered by the egg: those of the mother's digestive tract. I hope to identify among these bacteria those that attach preferentially to the surface of the eggshell, to understand if they are protective or rather at risk for the chick when it hatches. Therefore, I will try to evaluate the impact of the feed distributed to the birds and their housing (in cage or free range) on the orientation of their intestinal microbial flora, and therefore on the evolution of the surface flora of the egg. My work will help to better understand the role of this evolution in public health (eggs and meat), animal health and animal welfare.
