Impact of maternal antioxidant supplementation on ovarian development in prepuberal Iberian pig offspring.

ABSTRACT: A large percentage of breeding sows are culled before replacement costs are covered. Management and feeding are important factors affecting the performance of replacing gilts. Specifically, an optimal redox status has been linked to better fertility. Current research highlights the importance of neonatal criteria and age at puberty as factors in the gilt selection. Maternal antioxidant supplementation has benefits on the litter's performance, but there is scarce data on its effect on the future breeder. The aim of the study is to evaluate the effects of maternal supplementation with vitamin E (VE) and/or hydroxytyrosol (HXT) on prepuberal ovarian characteristics in Iberian pig offspring. Fifty Iberian sows were supplemented from day 85^th of gestation until weaning with 30 or 100
