Abstract
Introduction.The lactation curve of mammals can be
explained by mathematic functions which allow
relating milk production of a female individual through
time, taking into account her physiology throughout
the lactation period. Objective. To identify the
mathematic functions that can explain best the curve
of milk production in a population of female buffalos
from La Sierra, a village in the Puerto Nare town,
Antioquia, Colombia. Materials and methods. 3850
lactations were used for the study, they were divided
in groups according to their number and time of births
the buffalos had. Nine mathematic models of lactation
curves were used, both lineal and non-lineal. The
selection criteria for choosing the best model were
the highest percentage of significant curves and the
media of the determination coefficient. Results. The
model that best adjusted the lactation curve in female
buffalos was that proposed by Papajcsik and Bordero,
in 1988, which adjusted the curves in all the numbers
of births with all the birth époques a 100%.
Conclusion. The methodology to obtain the time at
the peak of the production and the production at its
maximum can be a useful tool for future works.
