The amount of feed fed to the respective experimental group was divided by the weight gain achieved in this experiment, and the criterion thus obtained was assigned to a criterion calculated similarly for the control rpynnbf. This value is the amount of feed, which in the relevant experimental group gives an increase in weight of 1 kg, counting on the amount of feed, which in the control group gives an increase in weight of 1 kg, in weight percent.

From the results of the experiments of Table 5, it can be seen that the animals, which were fattened with the use of new derivatives of hydrazugolic acid in accordance with the VII with the invention, showed a significantly higher weight gain than animals of the control and comparative groups. At the same time, the same weight gain can be achieved with a significantly smaller amount of feed, which indicates a significantly better implementation of feed (digestibility).
