Effect 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 observations
