The activities of amylase, trypsin and lipase in pancreas and the activity of pepsin in cardiac mucosa were measured in Jinhua and Landrace gilts at 35, 80 and 125 days of age, respectively. Jinhua gilts had lower total trypsin and total pepsin activities compared with Landrace gilts (P<0.01), and lower pepsin activity (per g of cardiac mucosa) at 80 days (P<0.05) and 125 days of age (P<0.01). In contrast, Jinhua gilts had higher amylase activity (per g of pancreas) and lipase activity (per kg of empty body weight) compared with Landrace gilts (P<0.001), and higher total amylase activity at 35 days (P<0.05) and 125 days (P<0.01) of age. Jinhua gilts had higher lipase activity (per g of pancreas) at 35 days (P<0.05), 80 days (P<0.01) and 125 (P<0.001) days of age.
