A study was conducted in the Mexican tropics to measure cattle cheese quality, under two feeding systems: grazing into a silvopastoral system (SS) - a mixture of grasses and forest leaves, adding 2.5 kg daily, of a slow intake urea supplement (SIUS), after cows were placed in confinement for 30 days, (15 d adaptation and 15 d milking); zero grazing (CS), fed with King grass (Penicetum purpureum) and sugar cane tops (Saccharum officinarum), supplemented with SIUS. The lowest content of saturated fatty acids SFA was found in cheeses from grazing animals. PUFA, omega-3 and CLA content in cheese from grazing cows was, on average, 33%, 28% and 49% higher than cheese from CS system. The highest total volatile organic compounds (VOC) content was found in SS cheese 443,9 arbitrary units (a.u.), the lowest were in CS “Colima” cheese (187,2 a.u). The sensory profile confirmed some differences between both systems. Cheeses from SS system have a greater intensity of the “herbaceous”, “fruity” and “milky”. The results have shown that the two feeding systems, even if both are mainly made up of fresh green forages, determine important variations in cheese quality.
