Ensuring the health and realization of the bioresource potential of calves with biopreparations

A new way of realizing the bioresource potential of calves during rearing and rearing is proposed due to the activation of nonspecific resistance of the organism with biological preparations Prevention-N-C and Salus-PE. The live weight of heifers of the control, 1st and 2nd experimental groups steadily increased until the end of the observation period, and the live weight indicators of animals of the 1st and 2nd experimental groups when prescribing biological preparations Prevention- N-C and Salus-PE, respectively, were significantly higher than in the control group. It has been established that immunoprophylaxis of newborn calves with complex biological preparations contributes to the prevention of respiratory and digestive diseases, activates growth during periods of cultivation using adaptive technology in individual homes, cultivation and rearing in standard rooms, with a more pronounced Salus-PER effect.
