Analysis of the Microbial Intestinal Tract in Broiler Chickens. CHICKENS

In the present work, we carried out the study of the microbiota by sequencing of 16S rRNA gene in four intestinal tracts and four ages of healthy broiler chickens under controlled farm and diet conditions. More precisely, 210 Ross-308 male chickens were raised according to the EU guidelines, fed on a commercial diet until slaughter at 47 days of age and the microbiota of duodenum, jejunum, ileum and caecum was analysed at 11, 24, 35 and 46 days of life. The microbiota resulted compositionally different for each gut tract and become mature and homogeneous 11 days after the chicks birth.
