Previous research has shown that parity (P) 4 progeny have greater weaning weights and decreased microbial diversity compared to P1 progeny. Three experiments were conducted to evaluate litter performance, passive immunity, and fecal microbiota among P1 and P3 dams and their progeny. In experiment 1, 56 P1 and 49 P3 dams and their progeny’s litter and growth performance, immunoglobulin (IgG and IgA) concentrations, and gut microbiota were evaluated. In experiment 2, 48 pigs per P were selected to determine growth performance, immunoglobulin (IgG and IgA) concentrations, and gut microbiota. In experiment 3, 8 dams per P were selected. At birth, …
