It has been reported recently (Stott, 1974) that in cattle, reproductive efficiency is increased by keeping the animals under cool climatic conditions. However, in buffaloes very limited information is available. Roy, Sengupta & Misra (1962) have reported that all buffaloes exhibited oestrus and were inseminated in a group protected from direct sun radiation whereas in a non-protected group only one showed oestrus. There is no systematic information available on the effect of wallowing and showers on the oestrual behaviour of buffaloes. Therefore, the present investigation was undertaken to study the effect of cooling on oestrual behaviour in buffaloes.
