Foi usado delineamento inteiramente casualizado com três tratamentos e cinco repetições. O FC apresentou 91,5% de matéria seca (MS), 93,89% de matéria orgânica (MO), 11,25% de proteína (PB), 4,31% de extrato etéreo (EE), 45,47% de fibra em detergente neutro (FDN), 37,08% de fibra em detergente ácido (FDA), 8,39% de hemicelulose (HE), 24,37% de celulose (CE), 12,52% de lignina e 6,30% de tanino condensado. Os consumos de MO e MS, em g/dia, g/kg0,75 e %PV; energia bruta (EB), em kcal/kg/dia e kcal/kg0,75; e dos componentes da parede celular foram reduzidos linearmente pelo aumento de FC na dieta. Os consumos de PB, proteína digestível (PD) e EE aumentaram linearmente com o aumento do FC na dieta. Os coeficientes de digestibilidade da MS, MO, PB e EB das dietas não foram afetados pela inclusão do FC. No entanto, observou-se redução linear para os coeficientes de digestibilidade da FDN, FDA, CE e EE e efeito quadrático para o coeficiente de digestibilidade da HE. Os consumos médios de MS e PB verificados nos níveis intermediários de FC atenderam as exigências de mantença dos animais. Fifteen male castrated sheep were used during a period of 22 days to determine the bromatological composition, intake and in vivo digestibility of diets with increasing levels (0, 50 and 100%) of catingueira hay (CH). A completely randomized experimental design with three treatment and five replications was used. Catingueira hay presented a 91.5% dry matter (DM), 93.89% organic matter (OM), 11.25% crude protein (CP), 4.31% ether extract (EE), 45.47% neutral detergent fiber (NDF), 37.08% acid detergent fiber (ADF), 8.39% hemicellulose (HE), 24.37% cellulose (CE), 12.52% lignin, 1.86% silica and 6.30% condensed tannin. The increased CH levels in the diet linearly reduced the intakes of OM and DM (express in g/day, g/kg.75 and %LW), of gross energy (GE) (express in kcal/kg.day and kcal/kg0,75) and of the cell wall components were. The intakes of CP, digestible protein (DP) and EE linearly increased as CH levels increased in the diet. The coefficients of digestibility of the DM, OM, CP and CE were not affected ed by inclusion of CH. However, a negative linear effect was observed for the coefficients digestibility of the NDF, ADF, CE and EE and a quadratic effect for the coefficient of digestibilities of HE. The average intake of DM and CP observed in the intermediate levels of CH attained the maintenance requirements of the animals.
