Abstract

An exploration was launched to assess the erythrocytic enzymatic responses in Magra sheep exposed to superimposed stressors. Superimposed stressors incorporated transportation and regrouping stressors along with extreme ambiences. Blood samples were collected from female Magra sheep ageing 3-7 months; 7-11 months; 11-15 months; and 15-19 months during moderate, dry-hot, humid-hot and extreme cold ambiences. Maximum temperature humidity index (THI) values observed were 76.44± 0.11; 87.23 ± 0.30; 89.32± 0.07 and 63.22± 0.11, respectively during moderate, dry-hot, humid-hot and extreme cold ambiences. Erythrocytic enzymatic responses were assessed by measuring catalase and glutathione reductase. The values among ambiences altered remarkably (p≤0.05) and dry-hot and humidhot ambiences showed maximum changes. Magra sheep of all the age groups were found influenced by the impact of superimposed stressors particularly when transportation and regrouping were associated together during dry-hot and humid-hot ambiences. It was concluded that erythrocytes showed intonations during exposure to superimposed stressors. Recommendations can be made that animals must be provided with proper water and antioxidants especially during stress periods.
