The aim of this study was to describe the reproductive seasonality in buffalo under tropical conditions in the Middle Magdalena, Colombia and its relation to climate parameters. Birth records of 30 571 animals from 1970 to 2013 and hydro-meteorological data from Puerto Berrio-Antioquia station were evaluated. For the analysis a Poisson regression and Spearman correlation was used to determine the relationship between the season of conception and births (expressed in percentage) with the following hydrometeorological variables: minimum, average and maximum monthly flow of rivers (m3/sec), mean values, maximum monthly river levels (cm), monthly total values of sunshine (oC), minimum, average and maximum monthly temperature (oC), mean monthly values of relative humidity (%), monthly maximum values of precipitation (mm in 24 h), monthly totals of precipitation (mm) and the temperature and hu...
