Summary. Blood samples were taken from 6 non-inseminated cyclic buffaloes for 1 calendar year. Plasma progesterone concentrations on the day of oestrus and also in the luteal phase of the cycle were significantly higher (P < 0·01) in the cooler (warm and cold) seasons than in the hot and dry and hot and humid seasons.
