Influence of succinic acid Acidum succinicum on chinchilla growth in postembryonic period

In animal husbandry, special attention is paid to biological additives and natural metabolites used in the development of feeds that ensure productivity of animals and increase resistance to adverse environmental factors. Such additives actively influence energy metabolism and do not harm even in case of an overdose, due to the absence of xenobiotic effects inherent in a large number of synthetic drugs. The purpose of the research was to study growth dynamics of chinchillas against the background of drug «Succinic acid forte». The experiments were carried out on chinchillas 55-61 days old. At the same time, succinic acid (Acidum succinicum) was given to the chinchillas of the experimental group for 30 days in addition to the main diet - 20 mg/kg of live weight, pre-mixed with a small amount of water, then chinchillas were fed individually from the syringe. Determination of the dynamics of live weight was carried out using individual weighing of animals at the beginning of the experiment when forming groups, and then every ten days before feeding. When analyzing the main productive indicators, a direct pattern was noted - use of succinic acid in the diet of young chinchillas led to an increase in growth rate. So, 20 days after the start of the experiment, indicators of absolute gain in live weight of experimental animals were 32.07 % (p = 0.001), and after 30 days - 45.34 % (p = < 0.001) more than in the control, where in the feeding of chinchillas, only the main diet was used without additional introduction of succinic acid.
