SEASONAL DYNAMICS OF CERTAIN BIOCHEMICAL BLOOD INDICES OF SIMMENTAL COWS OF AUSTRIAN SELECTION UNDER ECOLOGOECONOMIC CONDITIONS OF SOUTH URALS
The seasonal dynamics of protein and carbohydrate metabolism as energy resources of body functioning in Simmental cows of Austrian selection under new ecological-economic conditions have been studied. As result of studies it is established that winter and spring seasons are more stressgenic for animals as compared with the autumn and summer periods.
