Physiological adaptability of rambouillet sheep to seasonal migration in Jammu region

An investigation was undertaken to study physiological parameters in migratory Rambouillet sheep (24) during seasonal migration from Sheep Breeding Farm, Billawar to high altitude, Sarthal. Animals were divided into four groups (Gr I male sheep of 1–2 years, Gr II-male sheep of 2–4 years, Gr III-female sheep of 1–2 years and Gr IV-female sheep of 2–4 years). Physiological parameters were taken at weekly intervals during migration. Significantly (P<0.01) highest respiratory and pulse rates were recorded at 2^nd week and higher values were found at mid station. Rectal temperature was not showing any significant changes in various groups. Physiological parameters were found higher in young as compared to adult sheep. Respiration and pulse rates were higher in males as compared to females. However, rectal temperature was recorded slightly higher in female sheep. All the four groups of migratory Rambouillet sheep were found understress condition at mid stations and immediately after uphill migration, but adapted to the alpine pasture condition very quickly. Adult males were more adapted than females and young ones.
