Effect of different alternative roughages on the profitability of milk production systems with F1 Holstein x Zebu cows

ABSTRACT It was analyzed, by means of simulation, the effect of using four different rougahge alternatives during the dry period on the yield of milk production system using F1 Holstein x Gir cows. The rougahge alternatives were, as follows: 1) use of fresh sugar cane (Saccharum officinarum L.) for three months and corn silage (Zea mays L.) for three months, 2) use of corn silage for six months, 3) use of sorghum silage for six months, and 4) use of fresh sugar cane enriched with urea and ammonium sulfate for six months. The F1 Holstein x Gir herd of the Experimental Farm Felixlândia (FEFX) of the Agricultural Research Corporation of Minas Gerais (EPAMIG), located in the municipality of Felixlândia, state of Minas Gerais, central region of the state was used as reference. The inventory expenses, revenue and other data were registered in CUSTO BOVINO LEITE 1.0 software, aiming to generate the results for the profitability analysis. Fresh sugar cane was the rougahge alternative with the best profitability in milk production system with F1 Holstein x Gir cows, even with a smaller volume of milk produced.
