An experiment was carried out to determine the effect of supplementing ground pods of Enterolobium cyclocarpum in a basal ration of Pennisetum purpureum grass on feed intake, rumen volatile fatty acids (VFAs), and protozoa and methane (CH 4) production by hair sheep. Four male sheep (Pelibuey × Katahdin) with a mean live weight of 27.0 kg (SD ± 0.5) were supplemented with 0.00, 0.15, 0.30, and 0.45 kg of dry matter (DM) of E. cyclocarpum pods daily; equivalent to 0.00, 4.35, 8.70, and 13.05 g of crude saponins, respectively. Dry matter intake (DMI), organic matter intake (OMI), and molar proportions of propionic acid increased linearly (P <0.05) as pods of E. cyclocarpum in the ration were increased. Higher intakes of DM and OM were found when lambs were fed 0.45 kg DM per day of E. cyclocarpum , and the highest proportion of propionic acid (0.21 and 0.22, respectively) was obtained with 0.15 and 0.30 kg of DM per lamb of E. cyclocarpum, while apparent digestibility of neutral detergent fiber (NDF) and molar proportion of acetic acid were reduced (P <0.05). Rumen CH 4 production decreased (P < 0.05) when 0.30 and 0.45 kg of DM/lamb/day of E. cyclocarpum were fed (21.8 and 25.3 L CH 4/lamb/day, respectively). These results suggest that to improve the feeding of sheep fed tropical grass, it is advisable to supplement the basal ration with up to 0.30 kg DM of E. cyclocarpum pods.
