With the larger litter size from so

With the larger litter size from sows fed organic trace minerals, their litter birth weights were heavier (P < 0.05). However, when expressed on an individual pig
basis, piglet weights were similar between the 2 mineral sources. Sows fed the greater dietary Ca:P level had lighter (P < 0.05) litter birth weights, but individual
piglet weights were similar to the other sow treatment groups.Litter size was standardized within 3 d postpartum; thus, the number of pigs per litter at d 7 and at weaning (17 d) was similar among the 6 treatment groups. Individual pig ADG responses during the nursing period tended (P < 0.10) to be greater when sows were fed organic trace minerals, implying that these sows may have had greater milk productions.
