This work was carried out to evaluate the forage particle passage rates and ingestive behavior of dairy heifers from three genetic groups Holstein (H) and Zebu (Z) cattle (7/8HZ, 15/16HZ, Graded Holstein – GH), kept in feedlot regime and submitted to diets, in a total mixed ration, with two fiber levels (30 and 60%) of neutral detergent fiber (NDF), using chopped Elephant grass (Pennisetum purpureum, Schum., cv. Mineirão) as forage. The experiment was conducted in a 3 × 2 factorial […]
