There were no interactions
between the effects of treatments and parity on litter birth
weight, litter wean weight, daily litter weight gain, and
daily pig weight gain. Days return-to-estrus was similar (p
= 0.325) between the treatments and between the parities.
Conception rate at d 35 post-breeding for the subsequent
parity was similar between the treatments (93.4% and
91.0% for CON and YC, respectively).
