Іmmunophysiological adaptation and antioxidant potential of the organism of piglets under conditions of oxidative stress and the action of corrective factors

Abstract

The efficiency and profitability of intensive production of livestock products largely depend on the state of health and the ability of animals to withstand the effects of many environmental factors. A feature of farm animals' ability to adapt to various external influences and maintain the constancy of the internal environment. Given the problem of increasing the productivity and preservation of pigs, it is necessary to pay great attention to the study of metabolic processes in the body of piglets in the most critical periods of ontogenesis. The first critical period is considered to be 24 hours after farrowing. 10-14 days of life in piglets is the second critical period, which depends on the intensity of their growth, the number of heads in the nest, and the development of achlorhydria. The third critical period in raising piglets is 20-21 days of life. A decrease in colostral protection accompanies it. During this period, there was a shortage of mothers' milk. In this state, piglets are susceptible to diseases.
