PLASMA OESTROGEN CONCENTRATION IN NON-CYCLING MURRAH BUFFALO HEIFERS {BUBALUS BUBALIS)

Abstract

The present investigation was undertaken to estimate the basal circulating plasma oestrogen concentration in non-cycling Murrah buffalo heifers. Estrogen was estimated by radioimmuno assay in blood plasma. The plasma oestrogen concentration (pg/ml) ranged from 21.26 ± 0.54 to 23.25 ± 0.74, 20.69 ± 1.04 to 22.34 ± 0.66 and 21.41 ± 1.07 to 24.49 ± 0.80 respectively in 12, 24 and 30 months old buffalo heifers. From the investigation it reveals that plasma oestrogen concentration in Murrah buffalo heifers was at similar level at different ages.
