The reactivity and adaptation ability of the bulls-spermodonors in Krasnoyarsk region

The research objective was to study the reactivity and adaptation ability of manufacturing bulls in Krasnoyarsk Region. The research problems were to compare the changes of indicators of native semen of bulls of different breeds at the influence of paratypical factors; to track changes in quantitative and qualitative composition of their blood. Sperm, blood and serum of blood of the bulls of red and motley, black and motley, Holstein and Simmental breeds were the objects of the research. Native semen was estimated according to quantity and quality indicators. The coloring of dabs of blood was carried out according to Pappenheim, readingby four-field Filipchenko's method. In serum and blood carotene photometric and an alkaline reserve were determined by diffusive methods; the general protein calcium and phosphorus - by standard sets of JSC "Vector-Best"; ketone bodies, lipids, the content of macro-and microelements, amino acidson the device Bio Chem SA (Manufacturer ‘High Technology USA' (intermedia) in Krasnoyarsk Regional Veterinary Laboratory and Institute of Experimental Veterinary Science of Siberia and the Far East (Novosibirsk)...
