Effect of supplementing lactation and nursery pig diets with capsaicin on growth performance and gene expression of nursery pigs.

The objective of this study was to determine the effects of supplementing capsaicin in diets for lactating sows and their offspring on the growth performance and gene expression of pigs postweaning. Twenty-eight multiparous sows were fed corn-soybean meal-based diets without ( = 14) and with ( = 14) capsaicin (2.5 mg/kg) during a 19-d lactation period.
