Custos de produção de fêmeas bovinas da raça holandesa nas fases de cria e recria em um sistema de produção de leite no sul de Minas Gerais

Abstract

It was aimed to calculate the production cost of Holstein bovine females breed in theweaning and post-weaning phases and to identify the components that exert greatest influence onthe final operation costs. The data were collected on a dairy farm situated at Boa Esperança- MG.To calculate the total operational cost (TOC), all the effective operational expenses, as well as thedepreciation facilities and equipament. The animals reached 360 kg aged with 593 days, at 19.5months of life. The component items of the effective operational cost which exercised mostinfluence on the costs of the operation were in decreasing order, feeding (46.63%), that is, 31.89%with concentrates and 14.73% with roughage, purchase of animals in the weaning phase (22.81%);labor (16.53%); hire of machines for rationing (13.55%) and health (0.49%). The depreciationrepresented 15% of the TOC. The TOC was US$ 1,005.12, which corresponded to 3,400.67 kg ofmilk, representing a daily cost of US$ 2.00 or 6.76 kg of milk.
