| Popis: | The objective of this study was to evaluate the effects of inclusion of tropical tree foliage on intake, digestibility, and nitrogen balance in sheep fed with a diet based on fresh chopped Pennisetum purpureum. Four male Pelibuey sheep were used, with an average live weight of 22 ± 1.5 kg, distributed in a (4 × 4) Latin square design. Treatments were P. purpureum (T1), P. purpureum + Brosimum alicastrum (T2), P. purpureum + Guazuma ulmifolia (T3), and P. purpureum + Piscidia piscipula (T4). Tree foliage was incorporated into the ration at a proportion rate of 300 g/kg of dry matter (DM). Intake, digestibility, and nitrogen balance were measured during 24 h periods for 7 days. DM intake, organic matter (OM), and crude protein (CP) intakes were not affected (P > 0.05) by including tree foliage (an average of 892.7, 784.2, and 88.9 g/day, respectively). OM and CP digestibility was similar among treatments (P > 0.05). Nevertheless, digestibility of DM and NDF was lower (P |
