The purpose of this study is to determine the feasibility of using innovative tools to monitor the health status of cows following abomasum displacement surgery. To accomplish this goal, the following tasks were determined: to identify and compare differences in heart rate, respiratory rate, body temperature, and rumination in cows with omentopexy or toggle pin abomazopexy in left-sided abomasum displaced cows. To determine and compare changes in blood biochemical and morphological parameters in cows with left abomasum displacement, who have undergone omentopexy or toggle pin abomazopexy. To investigate and evaluate the relationship between investigated physiological parameters and blood morphological, biochemical parameters in the postoperative period. Provide recommendations for post-operative follow-up, considering the clinical benefits of non-invasive measures. 18 cows undergoing abomasum displacement return surgery were studied. 2 study groups were formed: omentopexy (9 cows) and toggle pin abomazopexy (9 cows). After each operation, an experimental sensor was applied, blood was collected 12 hours later, body temperature was measured, and daily rumination data was recorded. The following parameters were investigated: heart rate, respiratory rate, body temperature, rumination, blood biochemical and morphological parameters: leukocytes (WBC), erythrocytes (RBC), hemoglobin, platelets (PLT), glucose (Glu), betahydroxybutyrates (BHB), albumin (Alb), calcium (Ca), phosphorus (Phos), magnesium (Mg), alkaline phosphatase (ALP), asparagine transaminase (AST), gamma-glutamotransferase (GGT), alanine aminotransferase (ALT). Respiratory rate and heart rate were in normal range in both groups, but higher (7 %) in the omentopexy group. This change can be attributed to increased stress and pain during laparotomy. Rumination is a reliable indicator of abomasum displacement (reduced 100 %). It has been found that elevated glucose levels (9%) could help to monitor and control postoperative stress and pain, which is greater in the omentopexy group. Increases in liver parameters (AST 32%, GGT 57%, BHB 43%) in the omentopexy group indicate greater liver damage due to ketosis. In the study it was found that number of erythrocytes (22%), hemoglobin (21%), hematocrit (12%) is increased in the omentopexy group. Also, several statistically significant correlations between measured parameters were found. A negative correlation between erythrocytes and respiratory rate may indicate anemia and activation of the respiratory center. A positive correlation between respiratory rate and glucose concentration can be indicator of stress. A positive correlation between ruminant and glucose, also, a negative correlation between ALT and rumination may be indicator of improvement in the animal's condition. |
