Description

Diurnal patterns of food and water intakes, fecal and urine outputs, and locomotive activity were observed on beagles for three days continously. They were kept individually in cages at temperature 21-23°C, humidity 40-70% with a light time 7: 00-19: 00. The results showed that food and water intakes, and locomotive activity have diurnal patterns. Fecal and urine outputs have not diurnal patterns, but times of fecal and urine outputs is similar in many animals. The results suggest that physical condition is shown by quantitative values of behaviors, and sensitivity of diagnosis is raised by recognition of their diurnal patterns.
