Resumo

Four groups of horses of Brasileiro de Hipismo bred were submitted to fasting for 24 and 48 hours in order to study the absorption capacity of the small intestine. Two groups were fed with coast cross grass (Cynodon dactylon) and the other two groups with coast cross pasture and grains. At the end of the fasting periods, the groups received 1g of glucose/kg of body weight in a 20% solution through a nasogastric tube. Blood samples were collected immediately before and 70, 60, 120, 180, 240, 300, and 360 minutes after glucose administration. Glycemia was determined by the orthotoluidine method and insulin by radioimmunoassay. The animals which received grains showed larger increase in glycemia and insulinemia than those maintained on pasture regimen alone. The 48-hour fasting period induced higher glycemia and insulinemia levels than those observed after 24-hour fasting.
