Brasília, DF: Sociedade Brasileira de Zootecnia, 2015. 1 CD-ROM.c2015  aThis work aimed to evaluate effect of soybean oil supplementation on dairy production of crossbred dairy cows under grazing. Twenty ½ and ¾ Holstein x Gyr cows with average of 77 days of lactation and 19.8 kg of daily milk yield were used under grazing of palisade grass (Brachiaria brizantha cv. Marandu) managed by intermittent stocking. In a 2 x 2 crossover trial, cows were homogeneously distributed between two experimental groups: 1) Control (C) ? supplementation with concentrate ration without soybean oil; and 2) Soybean oil (SO) ? addition 3% of soybean oil in concentrate ration (dry matter basis). Inclusion of soybean oil did not affect daily milk yield (P&gt0.05) in relation to control group. However, considering cost of oil inclusion and only the milk yield, this feed strategy is not economically viable  adairy cattle  aGado Leiteiro  aEnergy source  aLipid supplementation  aSuplementação alimentar  aSuplementação lipídica1 aSANTIAGO, E.1 aCARVALHO, G.
