Objective: To establish milk stability using the alcohol test in cows with different feeding strategies in the tropical dairy system. Design/methodology/approach: Ten crossbred Holstein x Zebu cows whose milk frequently tested positive to the alcohol test were housed in individual yards and distributed into two groups. Experiment 1. T1: cows consumed dry Pangola grass (Digitaria eriantha); T2: cows consumed green Maralfalfa grass (Pennisetum violaceum). Forage was provided ad libitum. Experiment 2. T1 cows were supplemented with a concentrate with higher crude protein and metabolizable energy percentage than T2 cows; this percentage was gradually increased up to 4.0 kg. Milk was subjected to alcohol testing. Variance analyzes were performed under categorical data models. Results: Higher percentages of cases that tested positive for alcohol were observed in cows that consumed dry grass than in cows that consumed green grass (P
