MORPHOLOGICAL STATUS OF BLOOD IN PREGNANT COWS WITH OSTEOMALACIA
Under current conditions of livestock intensification, metabolic diseases are most widespread and account for up to 30% of all non-communicable animal diseases. Osteodystrophy in cows is one of these pathologies. Taking into account that up to present there are no clear criteria to evaluate the status of mineral metabolism in pregnant cows, that is, the criteria of adaptation (physiological) and pathological osteomalacia in pregnant cows, the research goal was to determine the features of blood morphological status in pregnant cows with osteomalacia. To pursue the goal, the studies were conducted in the production facilities of the Training Farm AO “Prigorodnoye” (the City of Barnaul) in autumn and winter period in comparable Black Pied cows. It was found that increased count of eosinophils in blood up to 5% and regenerative shift of neutrophils to immature cells in pregnant cows 10 days before calving are associated with pre-calving physiological state, as these changes in apparently healthy cows regain the physiological values in 2 months after calving. These changes of blood morphological status in pregnant cows 10 days before calving are physiological changes and should be considered as an adaptive ability of the organism.
