In the paper the process of acclimatization and adaptation of boars on climate and microclimate conditions are described. The process of growth and sexual maturity during the breeding and accustoming of boars in taking sperms in the centers of artificial insemination or breeding stations are analyzed. It is concluded that appropriate microclimate conditions may solve sterility provoked by climate conditions and even increase fertility of pigs. For purchased and imported young boars it is very important that animals are raised in a proper way and trained for mounting and semen collecting. Ejaculate in the native sperm of imported boars is better quality comparing to the ejaculate of home breeds, but they are sensitive to unspecific infections that can reduce spermatozoa vitality, damage acrosome, disturb spermatozoa maturation and thus influence fertilizing of diluted semen. Housing and nutrition of high-born breed boars has important role in maximal exploitation of producing ability especially on longevity and lifetime production of the imported boars.
