Eggshell and Feed Microbiota Do Not Represent Major Sources of Gut Anaerobes for Chickens in Commercial Production

Popis výsledku v původním jazyce

In this study, we addressed the origin of chicken gut microbiota in commercial production by comparison of eggshell and feed microbiota with caecal microbiota of 7-day-old chicks using microbiota analysis by 16S rRNA sequencing. In addition, we tested when during prenatal or neonatal development it is possible to successfully administer probiotics. We found that eggshell microbiota was a combination of environmental and adult hen gut microbiota but was completely different from caecal microbiota of 7-day-old chicks. Similarly, we observed that the composition of feed microbiota was different from caecal microbiota. Neither eggshell, nor feed acted as an important source of gut microbiota for the chickens in commercial production. Following experimental administration of potential probiotics, we found that chicks can be colonised only when already hatched and active. Spraying of eggs during egg incubation or hatching itself did not result in effective chick colonisation. Such conclusions should be considered when selecting and administering probiotics to chickens in hatcheries. Eggshells, feed or drinking water do not act as major sources of gut microbiota. Newly hatched chicks must be colonised from additional sources such as air dust with spores of Clostridiales. The natural colonisation starts only when chicks are already hatched since spraying of eggs or even chicks at the very beginning of the hatching process did not result in efficient colonisation.
