Impact of different forms of the intestinum cecum microbiome of broiler chickens

Abstract

The effect of trace elements on intestinal microflora of the intestinum cecum of broiler chickens was studied. One of the causes of reduced intestinal digestive function in birds is the overgrowth of microbial flora in the intestinal lumen, resulting in decreased chyme advancement and premature deconjugation of primary bile acids. Excess microbial flora can cause damage to the small intestinal epithelium because the metabolites of some microorganisms are cytotoxic. Determination of the number of microorganisms in the intestinum cecum of broilers is an important step in monitoring the viability of the organism. The intestinal microbiota is the largest and most complex microecosystem of animals. Microflora is not only involved in various metabolic pathways to regulate metabolism, but also plays an important role as an intermediary between food and host. Gut microbiota diversity and avian body health influence and shape each other, and the gut microbiota maintains a relatively balanced state with the host under sustained environmental regulation. The gut microbiota plays an important regulatory role in nutrient metabolism and immune defense. The paper presents a study of the effect of different forms of chromium (Cr): chloride (CrCl3), ultrafine particles (UFP Cr) and picolinate (CrPic) on the intestinal microflora of the intestinum cecum of broiler chickens. In the group receiving CrPic with the diet, the genus Bacteroides occupied more than 50%, which is more than half of the total abundance of this taxon, the number of Clostridium XlVb was much less abundant at 0.6%. Collectively, the present study characterized the dynamic changes in the microbial community of the intestinum cecum of broiler chickens under exposure to different forms of Cr. The addition of CrPic to the diet of broiler chickens significantly affected the microbial diversity of the intestinum cecum and caused changes in the microbial community characterized by an increase in the phylum Bacteroidetes, where Bacteroides species was the main one.
