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

Resumo

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.
