Immune status of young pigs different methods of their breeding using means Globigen® Pig Doser and Globigen® Jump Start

Abstract

The article deals with the influence of the use of means for young pigs Globigen® Pig Doser та Globigen® Jump Start, which due to the content of specific Ig Y have immunostimulatory properties. Assessing the level of nonspecific resistance of piglets, which are based on determining the content of T- and B-lymphocytes and their populations in the blood of animals 30-, 60- and 120-day-old, the trend of increasing the number of T-helpers, T-natural killers and B-lymphocytes in the experimental groups of animals of both farms. It was found that the content of T-helpers during single-phase rearing of pigs became more important under the action of Globigen® Pig Doser and ranged from 30.16−35.15 %, and during three-phase rearing – under the action of Globigen® Jump Start 34.58−35.08 %. An increase in the content of B-lymphocytes to the level of physiological norm was noted: FE PE “Glynjany Agro” (single-phase cultivation) in the first experimental group 16.75–19.45 %, in the second 17.66–21.11 %. At Ltd. “Meat Resources” (three-phase cultivation) 17.7–21.02 % and 18.91–21.01 %, respectively, in the first and second experimental groups. Regarding the indicators of the content of T-natural killers, there is a tendency to increase their number in the blood of animals of experimental groups by an average of 4.90 % for single-phase rearing and 3.09 % for three-phase rearing of pigs. Such data give grounds to claim that there is a formation of the immune response to the action of pathogens, which plays an important role in maintaining the barrier function of the intestinal mucosa, which in turn reduces mortality and increases the average daily gain of young pigs. Under the action of immunostimulants, the safety of piglets in FE PE “Glynjany Agro” (single-phase rearing) at 30 days of age increased to 81.3−93.7 %, and in Ltd. “Meat Resources” (three-phase rearing) to 80.0−86.7 %. In piglets FE PE “Glynjany Agro”, up to 120 days of age, the average daily gain was 0.710 and 0.691 kg using Globigen® Pig Doser and Globigen® Jump Start, and in piglets from Ltd. “Meat Resources” these figures were 0.595 and 0.628 kg.
