The effect of tobacco Hawkmoth caterpillar extract (Manduca sexta) on the growth and stress resistance of young animals

Article deals with the problem of reducing the level of stress and improving the growth and development of young animals during weaning from a nursing female. For this purpose, it is proposed to use an extract of larvae of tobacco hawkmoth (Manduca sexta), containing ecdysone and juvenile hormone. We studied the anxiety of animals in the experimental setup of the light-dark test. Authors conclude that the extract of tobacco hawk moth caterpillars reduces the anxiety of animals. This is manifested by an increase in the latency of entering the dark compartment of the light-dark dough, an increase in the time spent in the light compartment and a decrease in the number of boluses of the litter. It is possible to explain the large increase in body weight of experimental animals in comparison with the animals of the control group by reducing the level of stress and the anabolic effect of caterpillar extract.
