title: Luteinizing hormone in blood plasma of post-partum buffaloes (Bubalus bubalis).
abstract: The changes in luteinizing hormone concentration were measured by heterologous double-antibody radioimmunoassay in blood plasma of 28 Murrah buffaloes. The LH concentration fluctuated between 0.22 to 0.78 ng/ml during first 21 days post-partum. The level increased significantly (P < 0.001) at estrus. The basal LH concentration of second and third week post-partum was inversely related to the first post-partum ovulation interval.
