Evaluacíon económica de la producción lechera en el período 2014-2017. Estación Tunshi –ESPOCH.

Abstract

The economic evaluation of the milk production in the period 2014-2017 was carried out in the Tunshi- ESPOCH station, for which productive records of the cows in production were used, as well as the economic balances with which, it was analyzed taking into account the effects of the dry matter consumption environmental factors on the milk production of the different lactations of Holstein-Friesian cows from 2014 to 2017. The characterization included the calculation of the need for dry matter (MS) consumption was analyzed the economic behavior based on the volume of milk production (Its) per lactation in relation to MS consumption (Kg), using the values adjusted for lactation. Peak lactation performance at 305 days was lower in primiparous cows (80.5 / week and 2675.37 / lactation) compared to multiparous cows (106.78Its / week and 5160.90 its / lactation), lactation curves are described with an equation of fifth order. The calculated consumption of MS was 3250.07kg (90.46kgMS cow/week) primiparous and 5948.60kg (113.48kgMS cow/week) in the multiparous, during the production cycle. The consumption curves of MS are described with a third-order equation. The highest benefit is obtained in the fifth lactation with a value of 1.84 (USD), with a profit of 596.88 (USD / cow/lactation), the benefit and utility curves are described with a fifth order equation. It was determined that the cows are more profitable in the fifth lactation, reason why it is recommended the discarding of the same ones from the sixth lactation and that the productivity of the same ones increases as it reaches its productive maturity.
