The objective was to evaluate intake, apparent digestibility and preference for the sabiá and mororó hays in goats. The hays were made with material in the course of fruitage, being made up of leaves and fine branches in the Experimental Stations of São Bento do Una e Itambé belonging to the Agronomic Institute of Pernambuco (IPA). The intake and digestibility were evaluated in the field of sheep, goat, Department of Zootecnia of UFRPE depending on the rate of supply of food (3 and 5% body weight) by using eight goats housed in individual stalls, divided into design entirely at random in a factorial 2 x 2 (level of supply X hay) with four replications in time. To evaluate the feeding preference we used the same animals, housed in individual pens with access to hay while the two forage species in a completely randomized design with two treatments and eight repetitions. Significant difference (P> 0.05) in dry matter intake (DMI) for goats, depending on the level of supply, obtaining average values of 534.9 and 689.2 g / d, for the 3 and 5% respectively.The digestibility also differed significantly (P <0.05) in all variables, depending on the level of supply, with high level of provision of 5%. It was evidenced by the preference of goats for the sabiá hay because it represented 62.7% of total daily DMI when the two hays were offered simultaneously. The hay evaluated showed a high content of protein, but with considerable fraction of this nutrient unavailable to the animal. The goats showed clear preference for the sabiá hay to the dettriment of the mororó hay when given the opportunity to choose the food. The hay analyzed showed potential in protein supplementation for goats with an average body weight of 18 kg in the maintenance phase.
