摘要

The influence of new product combined feeds based on nontraditional feed additives on the morphological changes of the muscle tissue of the fish has been studied. Feed additives are natural minerals from deposits in Kazakhstan. The objects of the research were the fish (Nile tilapia) grown in the conditions of the Chondzhy natural hot spring in the Almaty region. The results of the research show that no histopathological changes were observed in the reference and the experimental groups, where fish had received the combined feed made according to new recipes.
