One of the ways to enhance sow productivity is to use various food supplements to stimulate digestion and uptake of the elements required for the accelerated development of animals. The list of such supplements is expanding every year and, according to experiments conducted, they yield good results. However, their controversial manifestation in the pork production process should be noted. The used supplements clearly affect this process optimality both in terms of the output and financial outlays. This work addresses the influence of protein-vitamin-mineral supplements (PVMS) on sow productivity, metabolism, and pork quality. The mathematical model has been used to substantiate the optimal alternative of the pork production technology for the PVMS under study. Addition of Provimi supplements to the pig diet has been found to enhance litter heaviness, sow milking capacity, the viability of piggery by the time of weaning, and to promote the growth of the young stock. In the bodies of piggery and sows, the use of supplements normalizes cobalt, manganese, and copper metabolism, increases the content of gamma globulins in the piggery serum, and improves pork nutritional and biological value.
