Fig. 1From: Effects of dietary valine supplementation during late gestation on the reproductive performance and mammary gland development of giltsEffects of dietary valine to lysine ratio during late gestation on the morphological characteristics of mammary tissue. LV: total valine: lysine = 0.63: 1; MV: total valine: lysine = 0.73: 1; HV: total valine: lysine = 0.93: 1. (a, b) shows the area of the lumen of alveolus of the mammary tissue of gilts at days 1 and 21 of lactation, n = 4.
