Effect of Dam Parity on Growth Performance and Immunity of Weaned Pigs

چکیده
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The growth performance of weaned pigs derived from different parities has not been previously evaluated; however, unpublished and anecdotal observations suggest that progeny derived from fi rst parity (P1) dams have reduced health status and growth performance compared to progeny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 objective of the current study was to evaluate the effect of dam parity on growth performance and immune response of P1 and P4 progeny during the nursery phase of production. Results from this experiment suggest that P4 progeny have increased body weight and growth performance during the nursery phase of production compared to P1 progeny. There were no effects of dam parity on immune response in this experiment.

The 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...
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 dietary lysine and valine fed during lactation on sow and litter performance.
Sows (98 first parity and 104 second parity) were used to determine the effects of dietary lysine and valine on lactation performance. Treatments were arranged in a 2 x 3 factorial with two levels of lysine (.80 or 1.20%) and three valine:lysine ratios (80, 100, or 120% of lysine). For all sows, increasing dietary lysine increased litter weaning weight (P < .001) and litter weight gain (P < .00...

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...
