Dynamics of biochemical indices of blood in bull-calfs imported breeds of meat cattle when growing in the steppe zone of Ukraine
Abstract
Studied in age aspect and seasonal parameters in blood dynamics. In the process of ontogenesis amount of blood in the body is increased. However, the relative weight of the animals total mass, regardless of its age bull-calfs all-breed was almost constant and varied within the range of 5–8 %, although the pattern has been identified that to 30 months relative content of blood and hemoglobin is lower than in newborns. Hematologic indicators changed in parallel with the change in live weight of cattle, but at different speeds and were due to metabolism, fluctuations of the environment: environmental factors, season of the year, the level of feeding and water availability. However, the experiment value remained within the limits of physiological norm and indicate good health and full value of feeding animals.Biochemical parameters of blood proved that gobies charolais, hererford, light ofaquitaineandlimousinbreeds are well adapted to the conditions of the steppe zone of Ukraine and exhibit a high genetic potential productivity.Therefore, hematological studies give reason to believe that the gobies studied breeds in the steppe zone of Ukraine it is expedient to raise the DL of 2,5 years of age in order to obtain heavy carcasses and high quality beef for cheap. This would accelerate the development of beef cattle in the countryI.thereby, satisfying the needs of the Ukrainian people in the meat.
