The feeding behavior and dry forage intake of ewe lambs receiving different types of supplementation on pearl millet (Pennisetum americanum (L.) Leeke) pasture was evaluated. Twenty-four ewe lambs with 30.2 ± 2.6 kg mean initial body weight (BW), distributed in three feeding strategies: grazing on pearl millet pasture; grazing on pearl millet pasture supplemented with cassava meal; and GL – grazing on pearl millet pasture supplemented with corn gluten meal. Supplements were provided in the amount of 1% of BW. The daily times (min/day) spent grazing, ruminating and idling, and the biting rate (bites/min) were evaluated on three dates. The dry matter intake (DMI) was estimated from the relationship between the fecal production (FC, g/day) and dry matter indigestibility by the in vitro method. The fecal excretion was estimated using chomium oxide as an outside marker. A randomized complete design was used, with three feeding strategies, two area replications and four tester animals per replication. Providing supplements decreased the daily grazing time, bite rate and bite mass. Pasture intake was lower among ewe lambs that received corn gluten than for those kept exclusively on pasture; however, dry matter total intake was higher when supplement fed (947 g for corn gluten supplementation; 907 g for cassava meal supplementation; and 652 g for exclusive pasture). Ewe lambs on pearl millet pasture without supplementation keep on grazing for more time.
