On the question of the duration of technological cycles of maintenance in the conditions of bioindustrialization pork meat production

To achieve the research goal, simulated experiments were conducted on two groups of suckling piglets with 15 heads each. They were kept from 2 to 60 days in a mother pigsty, then up to 300 days of life activity (the duration of the experiments) - in a pigsty-fattener. Group 1 animals served as a control. The peers of group 2 were fed shatrashanit against the background of the main diet according to the generally accepted scheme. Postnatal dynamics of the intensity of growth, hematological, biochemical and immunological parameters were studied in them. It was found that of the 18 studied indicators of the immunophysiological status of the organism, 13 factors (72.2 %) had the lowest intensity of increase by the end of the physiological maturity phase (300-day age - the end of the fattening period). On the basis of the revealed regularity, the expediency of keeping fattened pigs in the conditions of bioindustrial technology not older than 210-230 days of age is scientifically justified.
