Abstract
kg and 4.19 ? 0.03 kg. The lactation peak occurred in the second month with production of 4.03 kg. The goodness of fit and discrimination between the models demonstrated high fit in the square logarithmic model and polynomials, with two and three square segments. However, the polynomial with three square segments (Y=3.5281+ 0.6903X -0.1791X2+ 0.1818Z1+0.0922Z2) had significant parameters with the highest fit values and estimated with precision all the phases of the curve. It is considered that this model represented the best the mean lactation curve of the female buffaloes under the conditions of the enterprise.
Key words: curve, lactation, crossbred female buffaloes.
