The processing of oats grain (entire or grounded) on the performance of feedlot finished cull cows was studied. Cows were fed with 60% of corn silage and 40% of concentrate, composed by oats grain, urea, limestone and salt. The treatments were Treatment 1 with whole oats grain, Treatment 2 with 50% grounded grain, e Treatment 3 with 100% grounded grain. The data were analyzed by regression. Grinding did not affect dry matter intake, being the average values 10.563 kg/animal/day, 2.2% when expressed per 100 kg of live weight and 102.94 g when expressed per metabolic weight. Average daily weight gain increased linearly with the inclusion of grounded oats in the diet (Y=.79976+.0033X), while feed conversion declined linearly (Y=13.21155-.04021X). Subcutaneous fat thickness increased lenarly with the increase of grounded oats in the diet. The better use of the grounded oats resulted in higher weight gain and slaughter weight, which explains the higher fat deposition of cows fed with grounded oats.KEY WORDS: Feed conversion, intake, weight gain.
