SUMMARY
Eight Pelibuey hair sheep (45 [+ or -] 2.2kg body weight), cannulated in the rumen and kept in metabolic stalls in a roofed building, were used to determine the effect of the incorporation of com oil in a concentrate upon dry matter (DM) intake, rumen fermentation of DM, organic matter (OM) crude protein (CP) and neutral detergent fiber (NDF), as well as microbial N supply to the small intestine, Sheep were fed low-quality Guinea hay (Panicum maximum) grass ad libitum and 300g daily of a commercial concentrate to which 0, 4, 8 and 12% of com oil was added. Voluntary DM intake was measured and rumen fermentation of DM, OM, CP and NDF neutral detergent ...

<0,05), a medida que la concentracion de aceite se incremento (665,8 [+ or -] 35,1, 648,8 [+ or -] 35,1, 558,8 [+ or -] 36,3 y 525,3 [+ or -] 36,3 g/dia para 0, 4, 8 y 12% de aceite, respectivamente). La fermentacion ruminal (fracciones a, b y a+b) de la MS, MO, PC y FDN no mostraron diferencias significativas (P><0,05) a medida que a concentracao de azeite se incrementou (665,8 [+ or -] 35,1; 648,8 [+ or -] 35,1; 558,8 [+ or -] 36,3; e 525,3 [+ or -] 36,3g/dia para 0%, 4%, 8% e 12% de azeite, respectivamente). A fermentacao ruminal (fracoes a, b e a+b) da MS, MO, PC e FDN, nao mostraram diferencas significativas (P>
