Fig. 1From: Net absorption and liver metabolism of amino acids and heat production of portal-drained viscera and liver in multiparous sows during transition and lactationArterial insulin (a), urea (b), and CO2 (c) concentrations of sows during late gestation and in early and peak lactation. Influences of DIM were observed for arterial insulin (P < 0.001), urea (P < 0.001), and CO2 (P < 0.001) concentrations, respectively. Influences of time after feeding were observed for arterial insulin (P < 0.001), urea (P < 0.001), and CO2 (P < 0.001) concentrations, respectively. Interactions between time after feeding and DIM were observed for arterial insulin (P < 0.001), urea (P = 0.02), and CO2 (P = 0.008) concentrations, respectively. DIM, days in milkBack to article page
