Effect of Aerobic Exercise on the Hematological Parameters Modification in Horses Producing Monovalent Snake Antivenin

Snake antivenin production is associated with several hematological changes in horses affecting their health. Exercise training, as a non-pharmacological method has an important role in maintaining and improving livestock health. This study is aimed to investigate effect of aerobic exercise on the Hematological Parameters modification in Horses Producing monovalent snake Antivenin. Ten horses of mixed-breed of 8 to 5 years old with an average weight of 300-350 kg in antivenin production cycle were randomly divided into two groups of venom (V) and venom + exercise (TV) . The training protocol included 3 sessions of aerobic training in a week with medium intensity for 22 weeks. Each training session included of aerobic training with 50-60% of maxHR,. Blood samples were collected before and after training period through external jugular vein. Repeated measure method was used to analyze the data. Results showed that red blood cells count, hemoglobin, hematocrit, platelets count, white blood cells count, lymphocytes, and eosinophil decreased while MCH, MCHC, MCV, monocyte, and neutrophils increased significantly within both groups. However, these changes were not significant between the two groups (p≥0.05). Overall, the results of this study indicated that hematological changes in horses seem to be related to the venom and this intensity does not have a significant effect on hematological parameters modification in venom + exercise.
