A.  aAttractants for automated emission measurement (Greenfeed®) in pasture-based systems.h[electronic resource]  c2018  aThis study aimed to evaluate the frequency and intensity of GreenFeed (GF) use by Nellore steers using different attractants in pastures of integrated systems. The attractant protein supplement and Tifton bermudagrass pelleted hay flavored with vanilla were evaluated over a period of 15 days. The pelleted hay stimulated the animals to stay longer in the equipment (24.23 s), with 8% more visits in intervals longer than 30 s in contrast to protein supplement. This indicates that pelleted hay flavored with vanilla is a potential attractant to encourage Nellore steers to visit GF in grazing systems.  aBeef cattle  aGreenhouse gases  aEfeito Estufa  aGado de Corte  aEnteric methane  aIntegrated systems  aMitigation  aSustainable intensification1 aCARVALHO, P. de1 aCABRAL, L. da S.1 aRODRIGUES, R. de A.
