The objectives of this work were to identify the mathematical functions that better fitted the milk production of Guzera breed cows, to evaluate the effects of the environmental factors on the lactation curve format and to estimate the genetic parameters for the milk production and for the dependable components of the lactation curve format. A total of 1130 lactations from 583 Guzera breed cows, daughters of 165 bulls, with production over the period from 1983 to 1997 were used. The […]
