Effect of Dam Parity on Litter Performance and Passive Immunity
Litter performance and passive immunity may be affected by dam parity. 1 Summary Preliminary experiments (reported in the 2008 Nebraska Swine Report) suggest that progeny health status may be affected by dam parity. However, the preliminary experiments only included a small population of sows and their progeny. Therefore, the objective of the current experiment was to evaluate litter performanc...
متن کاملEffect of Dam Parity on Progeny Gastrointestinal Microbiota
The gastrointestinal microbiota of neonatal pigs may be affected by dam parity. Summary Litter performance, progeny growth performance, and progeny health status may be affected by dam parity. The objective of the current experiment was to evaluate gastrointestinal microfl ora, as a measure of gut health, in progeny derived from fi rst parity (P1) compared to fourth parity (P4) dams. Fecal samp...
متن کاملEffect of Dam Parity on Growth Performance and Immunity of Weaned Pigs
Growth performance in the nursery may be affected by dam parity. 1 Summary The growth performance of weaned pigs derived from different parities has not been previously evaluated; however, unpublished and anecdotal observations suggest that progeny derived from fi rst parity (P1) dams have reduced health status and growth performance compared to progeny derived from mature sows (≥ P2). The obje...
متن کاملEffect of dam parity on litter performance, transfer of passive immunity, and progeny microbial ecology.
Litter performance and progeny health status may be decreased in progeny derived from primiparous sows but improve with increasing parity. The objective was to evaluate litter performance, the production and passive transfer of Ig, and fecal microbial populations in progeny derived from first parity (P1) compared with fourth parity (P4) dams. Litter performance was recorded for P1 (n = 19) and ...
متن کاملThe Effect of Dam Parity on Progeny Growth Performance, Passive Immunity, and Gastrointestinal Microbiota
Previous research has shown that parity (P) 4 progeny have greater weaning weights and decreased microbial diversity. The objective of this experiment was to evaluate litter performance, passive immunity, and fecal microbiota among P1 (n = 56) and P3 (n = 49) dams and their progeny. Blood samples were collected from P1 and P3 dams on d 90 and 114 of gestation and d 0 of lactation and from their...
