Abstract

An experiment was conducted to compare voluntary intake and digestibility of dry matter (DM), crude protein (CP) and neutral detergent fiber (NDF) of guineagrass-clitoria mixed hay (GCH; 33:67%) and of rhodesgrass hay (RGH). Ten adult creole rams (35 kg mean liveweight) were assigned to the hays under evaluation according to a crossover experimental design. Higher voluntary DM intake (P < 0.05) was observed in rams fed GCH than in those fed RGH (919 vs. 669 g/d). Digestibility of DM (65.2 vs. 55.51%) and of CP (78.8 vs. 65.2%) were higher (P<0.05) in GCH than in RGH, whereas NDF digestibility of GCH (58.3%) and of RGH (53.9%) did not differ (P > 0.05). Feeding GCH resulted in a 61% relative increase in digestible DM intake with respect to RGH (599 vs. 371 g/d). Guineagrass-clitoria mixed hay is a promising alternative for use in the feeding of ruminants.
