Resumo: | This study evaluated the ingestive behavior of Hostein calves kept in two husbandry systems: feedlot or pasture. We examined the ingestive behavior of 11 male non-castrated calves, with average initial age of 75 days, six of which were individually penned, consuming corn silage and concentrate-based diet at a ratio of 40:60 (on a DM basis), and the remainder, on pearl millet pasture (Pennisetum americanum) receiving concentrate supplementation at 1.0% body weight. Evaluations were held from November to February, from 8:00 am to 6:00 pm. Feedlot calves stay longer (p < 0.05) in idle, both in lying and standing positions, while animals on pasture spent more time in eating and ruminating activities. Confined animals performed a higher number of daily meals, but of shorter duration each. In both production systems, rumination activity is preferably performed in lying position, however, rumination time in standing position is about 1.4 times longer for those kept on pasture. Animals kept on pasture show a lower efficiency of DM intake, greater number of ruminated boluses, which were ruminated for less time and with fewer cud chewings. |
