摘要：Study of the effect of molecular hydrogen on the behavior adaptation of chinchilla in conditions of cage keeping. The experimental animals received drinking water enriched with molecular hydrogen at a dosage of 0.1-1.1 ppm for 10 months. It was found that the peak of activity of the behavior of chinchillas of both groups fell on the period from 19:00 to 9:00. A significant difference between the experimental and control groups were identified by the shape of behavior “movement within the cage” activity in experimental group daytime was higher at 24 minutes (p˂0.05) than in the control. The dynamics of daily activity of experimental animals came eh for the period from 19:00 to 08:00 (on average by 12 minutes) and the control group - 22:00-08:00 (an average of 6 minutes). The introduction of drinking water enriched with molecular hydrogen into the diet of the experimental group of chinchillas for 10 months increased the proportion of active behavior of animals by 20.6%.
