Development of technology for bioenergetic evaluation of breeding bulls with different seed quality

Modern scientific data in the field of productive animals have made it possible to develop effective technologies for the production of animal products, but the reserves of biotechnological methods for diagnosing and correcting the productive and reproductive capabilities of the animal organism are far from exhausted. In this regard, it is of particular importance to clarify the fundamental mechanisms of life support of living systems, to develop reliable and informative methods for diagnosing the functional state, managing processes that ensure the realization of productive and reproductive capabilities of farm animals. The aim of the research was to study the functional homeostasis of animals with different reproductive capacity and seed quality based on bioenergetic evaluation of breeding bulls. The objects of research were the tested bulls of the black-mottled Holstein breed at the age of 12 months, as well as breeding bulls aged 2 to 4 years and their seed. The level of bioelectric potential was measured with an ELAP-type device in PLBAC No. 5,7,11,41,44. Localization and numbering of centers were adopted according to G.V. Kazeev (1994). The presence of reproductive disorders was established by the results of andrological medical examination of bulls at the age of 12 months. The presence of reproductive disorders was established by the results of andrological medical examination of bulls at the age of 12 months. According to the results of andrological dispensarization of the tested breeding bulls, animals with an average UBP of 68.85± 1.16 mcA differed in reproductive function disorders: aspermia, necrospermia, teratospermia, azospermia, etc. In the ejaculates of bulls with an average UBP of 74.53 ±1.33 µA, no anomalies were detected and the animals were recognized as healthy, without violations of reproductive function. In the experiments, a certain dependence of the activity level of the elements of the PLBAC system and the quality of semen spermatozoa associated with the nature of carrying sperm abnormalities was established.
