Abstract

A comparative study on variation in α-amino nitrogen, NEFA, urea and THI at various altitudes in mithun calves was carried out at Medziphema farm at an altitude of 300 MSL (A1) and Porba farm at altitude of 2100 MSL(A₂) Nagaland, India. The mithuns of either sex were selected and blood was collected at weekly interval. The values for α-amino nitrogen (mg/dl), NEFA (mg/l), Urea (mg/dl) and THI at A1 and A2 altitudes were 2.81±0.54 and 17.71±0.56; 22.16±1.95 and 31.25±1.63; 21.65±0.7 and 11.29±0.71; 72.01±0.32 and 63.47±0.31, respectively. The values obtained for α-amino nitrogen, NEFA, urea and THI differed significantly between the two altitudes. It was concluded that there was significant variation in α-amino nitrogen, NEFA, urea and THI at various altitudes in mithun calves.
