NOUEL-BORGES, Gustavo et al. Preliminary evaluation of Yacure (Phitecellobium dulce) leaves inclusion in rations for confined growing goats. Zootecnia Trop. [online]. 2012, vol.30, n.4, pp.343-350. ISSN 0798-7269.

Incorporation of pithecellobium dulce (pd) dehydrated leaves in rations for weanling goats with an average 14.92 ± 0.30 kg live weight and its effect on feed intake, nutrient digestibility and production when handled in total confinement were assessed. the pd ration was fed at four levels: 0 (pdo), 18.75 (pd19), 37.5 (pd38) and 56% (pd56) of dry matter (dm). ration icluded dehydrated pennisetum purpureum at 84.5, 65.75, 47.0 and 28.5% of dm, sugar cane molasses (15%) and a mixture of salt and minerals (0.5%), respectively. for treatments pd0, pd19, pd38 and pd56 voluntary intake (vi), dry matter digestibility (d), organic matter (om), neutral detergent insoluble fiber (ndf), acid detergent insoluble fiber (adf), and hemicellulose, and weight gain (wg), were determined. data was analyzed using a 4x4 latin square completely randomized design, with 16 crossbred weanling goats (creole × nubian) in four periods of 14 days each. the diets were offered daily to a level of 6% of pv in ms. the pd56 showed the best response to nutritional and productive vi 0.798 ± 0.01 kg dm / day, 5.42 ± 0.49% dm in pv; vi 695g om / day, vi 308g ndf / day, 66±8% dm d, 67±8% om d and 62±12% ndf d , and 222 ± 67 g / day of wg, allowing a high level of inclusion (56%) of pd in the diet with a high growth response of weanling goats.
