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.
Keywords: pig production, replacement gilts, sows, Large White breed, breeding value, animal assessment, BLUP method, macrocarpous, reproductive qualities, prolificacy, nest uniformity, live weight, daily average gain, L.Lash indexes as modified by N. Berezovsky, correlation relationship.
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.

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.

At a number of large pig farms, the staff recorded a pathology in piglets that was called «harefeet». The article describes possible reasons of the disease occurrence, methods of its treatment and prevention.
Keywords: pig production, piglet, population, microflora, bacterium, «harefeet», culling, claw, weanlings, antibiotic, prestarter, chelate silicon, selenium.
Regular farrowing with rhythmical production of piglets throughout a year is an important challenge for pig farmers. Solution of the challenge would allow a maximum use of the breeding stock, premises and manpower. Results of the experiments prove efficacy of the product Magestrofan® made by a Russian company Mosagrogen for arranging synchronous farrowing.
Keywords: pig production, piglet, sow, insemination, fertilisation, farrowing synchronisation, prostaglandin F2а, live weight, sow pregnancy, progesterone, Magestrofan®.
A method of drawing blood from superficial femoral veins of male pigs during mounting on phantom that was developed in France was successfully tested at large Russian pig farms.
Keywords: male pig, live weight, stress, superficial auricular and femoral veins, semen, mounting on phantom, ejaculation.
