Effect of pasture irrigation on the technical and management indicators of dairy farms

Abstract

The objective of this study was to evaluate the effect of pasture irrigation on the technical and management indicators of 20 demonstrative units participating in the “Balde Cheio” Program in the state of Rio de Janeiro from January to December 2011. The following variables were obtained: dam/labor ratio, herd size/labor ratio, milk yield/labor ratio, animals/production area, percentage of lactating cows, and milk yield. Return was analyzed considering gross margin, net margin, outcome (profit or loss), and profitability. The data were analyzed using the PASW 18.0 software. Pasture irrigation did not significantly alter the indicators studied. The greater profitability and return of farms using pasture irrigation were the consequence of better animal production rates/day and per ha/year. When gross margin, net margin and outcome using total revenue are considered, there is decapitalization of the farms.
