This study was carried out with the objective of determining the lactation curve of crossbred cows at the dual purpose herd of Turipaná, a Corpoica´s Research Center located in Cereté, Deparment of Córdoba, Colombia. Ninety two lactating records were analyzed using the quadratic regression model and the mathematical model Yt = a · tb · e-ct described by Wood (1967). The r2 values for the regression were 0.53 for cows in the first lactation (first order), 0.93 for cows in the second and third lactation (order 2) and 0.91 for cows of 4 or more lactation (order 3). The values of r2 for Wood´s model were 0.74, 0.89 and 0.80 for the orders 1, 2 and 3, respectively. According to Wood's model the peak oflactation was at 64, 46 and 38 days for ord...
