FORMATION OF PUBERTATE IN REPAIR PIGS WHEN USING NATURAL METABOLITES
Currently, in order to improve the productive qualities of animals, functional stimulants are increasingly used, i.e. dicarboxylic acids and their derivatives, which include succinic acid, which is involved in antioxidant protection, protein and energy metabolism, which is reflected in the growth and development of offspring, contributing to the improvement of the safety of livestock, the energy of growth and development of animals, as well as resistance to diseases. It was found that when using natural metabolites, the groups of experimental animals were characterized by different indicators of live weight, which is due to the influence of natural metabolites. So, from 6 to 9 months of agewhich were given succinic acid, differed in the highest indicators of absolute gain in live weight compared with the control group. The established difference in the absolute increase in live weight was 9,7 kg or 19,4% (P≤0,05). During this period they were distinguished by higher indicators of average daily gain in live weight, lower indicators were found in the pigs of control group, and the rest of the groups occupied an intermediate position.
