These challenges disproportionately impact the offspring of primiparous sows compared to those of multiparous counterparts. Little is known regarding potential interactions between parity and feed additives in the post-weaning period and their effects on nursery pig microbiomes. Therefore, the objective of this study was to investigate the effects of maternal parity on sow and offspring microbiomes and the influence of sow parity on pig fecal microbiome and performance in response to a prebiotic post-weaning. At weaning, piglets were allotted into three treatment groups: a standard nursery diet including pharmacological doses of Zn and Cu (Con), a group fed a commeJournal of animal science and biotechnology33https://www.ebi.ac.uk/biostudies/studies/S-EPMC10909285biostudies-literatureInteractions between maternal parity and feed additives drive the composition of pig gut microbiomes in the post-weaning period.PMC10909285Law KMurray DGarcia ERMUrriola PEHastad CGomez AfalseInteractions between maternal parity and feed additives drive the composition of pig gut microbiomes in the post-weaning period.<h4>Background</h4>Nursery pigs undergo stressors in the post-weaning period that result in production and welfare challenges.
