Native legumes and spineless cactus in supplementation of goats grazing in Caatinga rangeland: intake, performance, carcass characteristics, and meat quality

The study evaluated the performance, carcass characteristics, tissue composition, and meat quality of goats raised on pasture in the Caatinga rangeland supplemented with Leucena (Leucaena leucocephala) and Sabiá (Mimosa caesapiniifolia) hays associated or not with spineless cactus (Nopalea cochenill...

Description
Summary:	The study evaluated the performance, carcass characteristics, tissue composition, and meat quality of goats raised on pasture in the Caatinga rangeland supplemented with Leucena (Leucaena leucocephala) and Sabiá (Mimosa caesapiniifolia) hays associated or not with spineless cactus (Nopalea cochenillifera), and without supplementation. Thirty male castrated goats, no defined breed, with an average body weight of 15.5 kg ± 0.64 were used, distributed in a randomized block design, according to the initial weight of the animals. The experimental period lasted 105 days. The highest intake of DM, OM and CP occurred in the animals supplemented with Leucena hay associated or not with spineless cactus. The intake of NDF was higher (p <0.05) for animals fed only with Leucena and Sabiá hays. The highest intake of TDN was observed for diets, only grazing, and hays associated with spineless cactus. The daily weight gain for goats fed with Leucena hay and spineless cactus was 68.5% higher (p <0.05) than on grazing alone. Consequently, they obtained the highest (p <0.05) weights and yields of carcasses, shoulder, loin, and leg cuts, conformation and finishing scores, leg muscle index, and % fat in the leg of goats. The meat quality did not differ. The supplementation with Leucena hay associated with spineless cactus improves performance, weights, and yields of the carcass, commercial cuts, leg muscle of goats grazing in the Caatinga rangeland.
