Abstrakt

During the suckling phase, piglets are commonly housed in the same pen as their mother sows until weaning. Consequently, the mother's feces are a rich source of microbes for the colonization of the neonatal gut. In the past, mainly maturational changes in the bacterial community of piglet's gut have been investigated, whereas other microbial groups, such as fungi, received less attention. In the present study, we could show that the bacterial and fungal communities in sow feces changed with progressing lactation and that bacterial and fungal taxa present in sow feces were also present in gastric and cecal digesta of the suckling piglets. These findings support the importance of maternal microbes for the gut colonization of neonatal piglets. In both, bacterial and fungal communities, weaning left a characteristic mark on the overall community structures and relative taxa abundances, which can be explained by the withdrawal of sow milk and low feed intake. Correlation analysis also revealed potential bacterial and fungal marker candidates for softer and firmer feces.
