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.
The authors believe that for stable increase in the output of high-quality commercial pork and improvement of profit of agricultural enterprises it is necessary to receive young animals both for herd reproduction and fattening only from single replacement gilts.

To produce commercial hybrids of pigs and improve properties of their meat in conditions of industrial technology, Russian scientists developed a complex of selection genetic methods.

Self-developing species compliance pig breeding suggests refusal of such production group as basic sows, and receiving commercial piglets exclusively from single sows.

Today, manual way of receiving sperm from male pigs using a sow phantom is considered one of the most effective ways. Sperm is taken during mounting of the stud boar on a phantom or dummy sow.
Keywords: pig production, male pig, stud boar, sow, young boar pigs, phantom, sperm, ejaculate, prepuce, artificial vagina, erection, sexual reflexes, seminal fluid.
Effect of aqueous-alcohol emulsion of propolis and natural zeolites as well as their combination on growth, development and meat productivity of young pigs aged from two to eight months was determined.
