Короткий опис(реферат):
This work highlights the feasibility of finding new methods of influencing and adjusting the immunobiological reactivity of animals, particularly pigs, which plays a decisive role in the development of the body's adaptive reactions. The problem of increasing the industry's profitability, as one of those that gives a quick return, is solved mainly by reviewing and improving approaches to feeding conditions and filling and balancing rations. The conditions of raising and keeping animals, particularly hygienic and sanitary, are of great importance. However, very often, the hygienic factor is either not taken into account by product manufacturers, or they do not focus on it, considering it insignificant.
