Abstract

Lactose tolerance was studied in suckling piglets 7-8 days of age with diarrhea. The contents of lactose, lactic acid and water in diarrhea stools were significantly higher than those in normal feces (P<0.001), and thus pH was significantly lower in diarrheal stools (P<0.001). Afler oral administration of 2g/kg lactose increase of blood plasma glucose concentration was significantly smaller in piglets with diarrhea than in normal piglets (P<0.001). However, when lactose was given with β-galactosidase supplement or glucose alone (0.5-4.0g/kg) was administered, there was no significant difference in the concentration of plasma glucose between the piglets with diarrhea and those without.
