In pig production, breeding is based on definition of a large number of productive and performance traits of the animals as well as interrelations between the selected traits. The experts also use the method of consecutive selection for several traits, the so-called tandem selection.

Use of protein energy concentrate (PEC) allows diet balancing for protein and energy without additional application of others high-protein feeds, renders beneficial effect on morphological and biochemical indicators of blood and metabolism, promotes a better yield of meat, bones and skins, and smaller yield of pork fat, and also allows an increase in daily average gain by 3.07% per head.

Use of an infrared system in industrial pork production increases live weight gain by 10–15%, reduces mortality by 3–7%, and reduces fuel and energy consumption by a factor of 1.5–2.

Breeding value of the Large White pig was assessed for replacement gilts using indicators of own productivity and for sows for reproductive qualities as well for the degree of correlation between the signs with low heritability estimate.

Sterility is the most common reason of incomplete restoration of a herd, untimely replacement of culled animals and untimely creation of production groups and cycles. Elimination of the shortcomings in sow feeding and housing will help to improve their productivity and extend their useful lifetime.

Product VevoVital® by the company DSM is a superpure source of benzoic acid. The product was specially developed as a feed additive for pigs: it improves productive qualities of the population, improves feed eating and reduces ammonia content in the air of premises.

Inclusion of a new BASF-made hybrid phytase Natuphos Е in low-phosphor mixed feeds considerably improves phosphor digestibility, optimises bone tissue mineralization and has a positive effect on piglet productivity indicators. In terms of efficacy, Natuphos Е considerably surpasses its predecessor Natuphos.
