THE EFFECT OF AN IMMUNOMODULATOR ON THE PRODUCTIVITY OF CALVES DURING COLOSTRUM AND LACTATION

Due to the increased demands for productivity in the livestock industry, various ways of using tools and methods that affect the reduction of losses from diseases and underdevelopment of the body are currently being studied. Thus, a modern approach to therapeutic and preventive measures is being formed in the breeding and rearing of cattle and other animal species. In the context of sanctions from many states, animal husbandry in Russia requires increased attention to providing food that is economically beneficial for agricultural enterprises. From an economic point of view, agricultural enterprises should take care of minimizing productivity losses and the safety of the animals used, as well as increasing productivity indicators, including in accessible and newly mastered ways. The creation of optimal conditions for keeping and feeding animals, as well as timely disease prevention and treatment at an early stage, plays an important role here. In the prevention and treatment of diseases, drugs that stimulate the production of immune cells have recently been in demand. Such drugs include immunomodulators – immunostimulants. Immunomodulators are used both separately from other medicinal substances and in combination with certain indications. It is known that calves with developed immunity are less susceptible to diseases and have shorter recovery times compared to animals with weakened immunity. In the long term, animals whose development has not been stunted as a result of diseases have a greater potential for forming a highly productive dairy herd.
