Efeito da frequência de ordenhas de vacas mestiças na rentabilidade da atividade leiteira

Abstract

The effect of the use of a system with four milkings in early lactation of crossbred cows on the profitability of dairy farming of a milk production system was analyzed by means of simulation. During the rainy season, in the summer season, the cows were kept on pastures and during the dry season, they were confined with the use of in natura sugar cane enriched with urea and ammonium sulfate. The husbandry l reference was from the herd composed of Holstein x Gir F1 cows from the Experimental Farm of Felixlândia (FEFX) of the Agricultural Research Corporation of Minas Gerais (EPAMIG), located in the municipality of FelixlândiaMG, central region of the state. The inventory, as well as expenditures, revenue and the other data were registered on COST BOVINE MILK 1.0 software aiming to obtain profitability analysis. The use of a frequency of four milkings in early lactation improved the profitability of a system of milk production with F1 Holstein x Gir cows.
