CLINICAL AND HEMATOLOGICAL PARAMETERS OF COWS OF THE NORTHERN–EASTERN BIOGEOCHEMICAL ZONE OF UKRAINE AT DIFFERENT PERIODS OF LACTATION
Complicating effect of the adverse technogenic environmental factors that cause changes of biogeocoenose at the interaction with the natural deficiency of biogenic microelements, contributes to appearing and spread of pathology of mineral metabolism in farm animals, particularly in lactating cows. The question about the impact of the northern–eastern biogeochemical zone of Ukraine on the clinical and hematological parameters of cows at lactation’s period is studied insufficiently.
The research was conducted in the three farms of Chernihiv region (northern–eastern biogeochemical zone).
In the article the materials of our scientific research on determination of the clinical indicators among cows (heart rate, respiratory rate) are represented. The experimental diagnostic system is built on the principle: the sensor – amplifier – generator USW – modulator frequencies – antenna transmitter – receiver antenna – receiver – the computer. Blood was tested on the biochemical analyzer «Labline – 010» with standard set of reagents and the keeping conditions and ration of feeding cows were analized according to conventional methods.
The benefits of remote diagnostic device for clinical signs of cows by researcher’s saving time on 37.5% are established. The clinical indicators and main indicators of metabolism among cows of the northern–eastern biogeochemical zones in the 8 – 15, 55 – 65, 150 – 170 day of lactation and 55 – 60 days befor calving are investigated.
