Abstract

Abstract: A total of sixteen Duroc×Landrace×Yordshire female piglets (average BW of (8.0±0.4) kg) weaned at 28 day of age were used to determine the effects of different starch sources on fractional synthesis rate (FSR) of splanchnic tissues by an intraperitioneal injection of a flooding dose of L-[²H₅] phenylalanine (1.5 mmol/kg. BW). The results showed that the starch in corn diet enhanced the FSR of splanchnic tissues in weaning piglets. The FSR of corn groups was higher than other three groups. The FSR of duodenum, jejunum, ileum, colon, pancreas and liver in corn group were 85.87%, 47.47%, 37.29%, 56.29%, 43.55% and 17.63% higher compared with the stick rice group, respectively. These findings suggested that the different source starches affected significantly the FSR of splanchnic tissues in weaned female piglets.
