Production costs of bovine females of Holstein breed in the pre and post weaning phases in a milk production system at Southern Minas Gerais

Abstract

It was aimed to calculate the production cost of Holstein bovine females breed in the weaning and post-weaning phases and to identify the components that exert greatest influence on the 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 the depreciation facilities and equipament. The animals reached 360 kg aged with 593 days, at 19.5 months of life. The component items of the effective operational cost which exercised most influence 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 depreciation represented 15% of the TOC. The TOC was US$ 1,005.12, which corresponded to 3,400.67 kg of milk, representing a daily cost of US$ 2.00 or 6.76 kg of milk.
