Twenty-one mixed-parity (average 2.4 +/- 0.49) crossbred sows and their offspring were used to determine whether sow milk @entity50341 at farrowing was related to neonatal serum @entity50341 and @entity1707 growth to weaning. During farrowing, @entity1707 were randomly allotted to suckling (n = 99) or delayed suckling (n = 89) groups, with delayed suckling @entity1707 placed in a group pen apart from the dam before suckling. Both groups had access to heat lamps. Colostrum samples were collected no more than 2 h after farrowing the first @entity1707 . Blood samples were collected from all @entity1707 approximately 2 h after farrowing was complete; @entity1707 were then ear notched and returned to their dams. @entity1707 BW was recorded at 1.2 +/- 0.04 d of age and again at weaning. Milk and blood serum were collected after centrifugation; @entity50341 concentrations were estimated using RIA. @entity50341 was detected in colostral milk, as expected, and averaged 46.0 +/- 1.1 ng/mL. Pig serum @entity50341 (P < 0.02) was greater in suckling @entity1707 than in delayed suckling @entity1707 , averaging 0.69 +/- 0.08 and 0.54 +/- 0.07 ng/mL, respectively. Although male @entity1707 were heavier (P < 0.01) at birth than female @entity1707 (1,507 +/- 52 vs. 1,381 +/- 43 g), @entity9365 to weaning and weaning weights were similar for both sexes, averaging 229 +/- 14 g and 5,829 +/- 323 g, respectively, for all pigs; serum @entity50341 concentrations were not affected by sex of the pig. Milk serum @entity50341 was not associated with litter size, parity, @entity1707 birth weight, @entity9365 to weaning, or weaning weight. Suckling status did not influence @entity9365 to weaning or weaning weight of @entity1707 ; neonatal pig serum @entity50341 was not related to birth weight, weaning weight, or @entity9365 to weaning. These results indicate that @entity50341 is not directly related to early neonatal growth in the @entity1707 ; however, more in-depth studies are needed to determine possible indirect or long-term effects of early @entity50341 exposure.
