In three metabolic experiments in seven balance periods the effect of 20-hydroxyecdysone on proteosynthesis in growing pigs was studied in 30 individuals. On an identical genotype of animals, doses of 0.2 mg/kg of body weight and 0.4 mg/kg of body weight were examined. Effectiveness was found already in a dose of 0.2 mg/kg body weight and it resulted in higher values of resorption and retention of nitrogen experimental animals. Statistically significant differences were observed particularly in the third experiment where a high significance (P/-0.01) of protein deposition in animal bodies was found. In two feeding experiments (40 animals), a higher increase in body weight by 12-16% in the period of 30 days after administration of macromolecular pellets of 20-hydroxyecdysone was found. Also lower consumption of feedstuffs by 11-17% per 1 kg of an increase in body weight was found. In the evaluation of the principal meat parts of slaughtered animals after the termination of feeding (109.5 kg of body weight) the values were not statistically significant in comparison with the control group.
