| dc.description.abstract | Study was conducted on four breeds of sheep viz. Rambouillet, Polwarth, Gaddi x Rambouillet, Gaddi x Merino, migrating from mid hill areas to high altitude alpine pasture during summer. Physiological, blood biochemical, hormonal, macro and micro mineral changes at different altitudes during migration were investigated. Physiological studies revealed that rate of respiration at different migratory stations was faster in crossbreds, as compared to exotic ewes. Heart rate and rectal temperature varied non-significantly during migration. Intense salt hunger behaviour was recorded at high altitude pasture. TLC was higher during down hill migration as compared to up hill migration, where as TEC, haemoglobin and PCV were increased at high altitude pasture and subsequently remained high at mid station. Blood glucose level declined, whereas plasma cholesterol increased significantly at high altitude pasture. Plasma creatinine level was significantly high in crossbred sheep, whereas at nadir level in exotic ewes at high altitude pasture. An increase in AST and ALT activities was recorded at alpine pasture. Decline in plasma sodium level in different groups of sheep high altitude pasture may be attributed to high concentration of potassium (152.60 ± 10.97 ms/gm) in the grasses of pasture. Plasma zinc and iron levels increased at high altitude pasture possibly due to high dietary intake through pasture grasses, however relative decline in copper was due to increased iron intake. Thyroidal hormonal profile of Rambouillet and Polwarth ewes increased, indicating stress at high altitude, however decline in T3 and T4 during down hill migration reflects adaptation to continued exposure to cold climate at high altitude pasture. Mineral profile of grasses, soil and water indicated a positive correlation with animal system and found that exotic ewes are better than crossbred in terms of production, however adaptability to migratory conditions was better in crossbreds. | |
