Diagnostic stage of obstetric dispensary of cows in the conditions of PAE “Shpanivske” of Rivne district of Rivne region
The problem of obstetric pathology of cows is one of the first non-communicable diseases of animals. To eliminate it, a system of medical examination of cows has been developed, which includes a set of diagnostic, treatment and preventive measures aimed at reproduction of herds and obtaining healthy animals. The aim of the work was to study the prevalence of obstetric pathology, to determine the toxic and biochemical parameters and inorganic elements in the serum of cows in the period before launch and after calving in PSP “Shpanivske” Rivne district of Rivne region. Taken 15 blood samples from cows from different physiological groups (1 group – cows after calving, 2 – cows before start). The research was carried out by conventional methods on ImmunoChem-2100 – multifunctional microplate photometer and Immunochem-2200-2 – thermoshaker on 2 tablets using a set of reagents from “Philisit-Diagnostics” and “Vector-Best” and the content of inorganic elements. absorption spectrophotometer C-115M1. According to the results of obstetric examination of cows, conducted in the dry period, revealed: ketosis – 12.4 %, fatty hepatodystrophy – 11.7 %, udder edema – 8.8 % and subclinical mastitis – 23.6 % of animals. In 67.8 % of cows in the dry period with ketosis, the level of ketone bodies was at the level of 2.2 ± 0.01 mmol/l, and after birth they developed postpartum paresis – 18.3 %, postpartum endometritis – 27.9 % and delay manure – 26.7 %. Dry cows were diagnosed with a decrease in total cholesterol by 23.9 % relative to the lower reference value, and in cows after start – recorded an increase in total protein by 1.7 %, total globulin by 0.5 %, urea content by 23.3 % relative to the upper reference level and a decrease in glucose of 36.0 % relative to the lower reference level. There was also a decrease in the content of Zinc after childbirth by 22.0 % and in the period of dryness by 21.7 % and inorganic Phosphorus after childbirth by 28.2 % and in the period of dryness by 18.6 % relative to the lower reference level. In the future, further research will determine the quality of feed and develop schemes for immunocorrection of cows during the dry season and after calving.
