Pharmacological correction of technological stress in bulls and assessment of the influence of stress factors on semen quality

Abstract

The current conditions for the intensification of animal husbandry dictate a significant increase in the physiological and functional load on the body of productive animals, resulting in a failure of adaptive capacity, which manifest themselves in the violation of reproduction function and the development of pathological states. Research by domestic and foreign scientists has shown that stress plays a leading role in the etiology and pathogenesis of diseases leading to a reduction in animal reproduction [3, 4, 9]. Although the topic of stress is often covered in the scientific literature, some of its features are not fully explored. This is particularly true for male producers whose genetic material has a direct impact on livestock productivity and livestock production [1, 3, 4, 11]. Therefore, the study of the influence of stress factors on the reproductive capacity of males and their pharmaco-rectification is relevant. The aim of our research was to assess the degree of influence of technological stress factors on the reproduction function of the bull producers and to develop a pharmaco-correction scheme to prevent stress effects on sperm quality. In relation to the objective, the following objectives were proposed: 1. Study the reaction of the ox producers to the effects of technological stress; 2. Determine the influence of drugs Amber biostimulator, Azoxyvet on the quality of bull sperm.
