Fig. 2From: Glucosamine supplementation during late gestation alters placental development and increases litter sizeEffect of fetal and placental weight on fetal serum fructose-glucosamine treated (a), glucose treated (b). Response surfaces differed between treatments (fructose = 5.6916 + 0.00098(fetal weight) + 0.00185(placental weight) for glucosamine supplemented gilts; fructose = 6.1504 + 0.00438(fetal weight) – 0.01363(placental weight); slope for fetal weight P = 0.09; slope for placental weight P < 0.05). Within glucose-treated gilts, the white line indicates the fructose concentration where the effects of placental and fetal weight balance, which is at a ratio of 0.32. Means with number of observations are included at positions within the surface plots to reflect how well the surface plots corresponds with the actual observationsBack to article page
