[Results and problems of a new breeding method in pig husbandry].
The results and problems are referred to of the mass and model implementation in this country in the past 5 years of biotechnical methods of reproduction in industrial pig farming, namely: 1. Methods employed on a mass scale in the field of artificial insemination, synchronization of estrus with replacement pigs, diagnosis of early pregnancy along with hormonal methods for the stimulation of conception and prolificacy of sows. 2. Methods of model implementation -- programmed farrowing with the use of prostaglandin F2 alpha, hormonal protection of embryogenesis along with apparatus methods determining the most appropriate time of insemination. 3. Methods in the phase of scientific development -- insemination with deep-frozen semen, implantation of fertilized zygotes, programming of ovulation, and others. Established were organizational and administrative advantages and the veterinary and zootechnical of these methods.
