Practical application of the physiological and biological activity of superficially localized biological active centers (SLBAC) in the assessment of the productive potential of bulls-sires

In the context of large-scale breeding in dairy cattle breeding, the maximum possible use of breeding bulls is the most important task. The purpose of the research is to study the relationship between the physiological and biological activity of SLBAC indicators and the assessment of the quality of sperm production of breeding bulls. Research was conducted on the basis of JSC "Orlovskoe" on breeding work. The object of the study was producer bulls of different origins and their lactating daughters. The material for the study was the cards of breeding records and documents of primary zootechnical accounting. The conducted series of studies allowed us to establish the following: the level of bioelectric potential OF plbats of bulls-producers is interconnected with their breed affiliation. The use of the physiological and biological activity of the SLBAC system makes it possible to evaluate the quality of spermatozoa before taking the seed and thereby reduce the time and labor costs
