The dynamics of the content of immunoglobulins in the blood serum of piglets according to the actions of immunostimulating agents

Inconsistency in housing and feeding conditions, production stress, a combination of environmental factors, and technological solutions reduce the protective properties of the animal body, which often leads to a decrease in their productive properties. The work aimed to investigate changes in indicators of the humoral protection factor, in particular, the quantitative composition of immunoglobulins M, G, and A in the body of young pigs under the influence of immunostimulating agents Globigen® Pig Doser and Globigen® Jump Start, which include specific Ig Y. To perform this task in the conditions of the private farm of FG PE "Glynyany Agro" of Lviv region, Zolochiv district, which uses a single-phase method of raising pigs, a study was conducted with the involvement of 36 piglets-analogues of crossbreeds of the Great White and Landrace breeds, which were formed into three groups of 12 animals each. Piglets of the control group were fed feed of a standard diet. The piglets of the first experimental group were orally administered 2 ml/g of Globigen®Pig Doser during the first three days after birth. Then, according to the technology, they consumed the feed prescribed in the diet. The piglets of the second experimental group were given Globigen®Jump Start, which was mixed with the feed of the basic ration in the amount of 2 kg per ton of feed and, starting from the age of 7 days, was fed to the piglets according to the technology. It was established that the use of immunostimulating agents was characterized by an increase in Ig G and Ig A in the blood serum of piglets in the most critical period of their lives. Thus, in the blood serum of 30-day-old piglets under the influence of Globigen® Pig Doser, with a high level of probability (Р < 0.01), an increase of this class of antibodies to the level of 13.47 mg/ml was detected, with the use of Globigen® Jump Start, this indicator reached the mark 12.51 mg/ml. Since this period, colostral immunity, represented by placental immunoglobulins of class G and colostrum immunoglobulins of class A, is already exhausted; we assume that the formation of the body's immune response of young pigs has begun. We believe that the increase in the content of class A immunoglobulins, most likely the secretory form of the piglets themselves, when using Globigen® Jump Start, which reached the mark of 1.48 mg/ml, indicates the formation of immune resistance mechanisms. The effectiveness, specificity, and mechanism of action of these agents is based on the ability of their components, particularly Ig Y, to bind to pathogens or their fragments, to neutralize and safely remove them from the body, which helps to increase the barrier function of the intestinal mucosa. The obtained research results confirm the practicality of using Globigen® Pig Doser and Globigen® Jump Start immunostimulants during single-phase rearing of piglets to increase the level of non-specific resistance and obtain healthy young animals with a high level of viability.
