The study was carried out at the Embrapa Eastern Amazon, in Belem, Para State, Brazil (1º28'S 48º27'W of Greenwich), with the objective of evaluate the influence of the addition of the Cratylia argentea as alternative feed supplementation of ruminants, in the critical periods of forage production of in the Eastern Amazon. The nutritional characteristics of the leguminous was determined during twenty one days, using sixteen sheep, in individual metabolic cage, distributed in a completely randomized experimental design, with four treatments and four replications. The experimental rations (T1, T2, T3 and T4) contained Brachiaria humidicola and crescent levels of 25%, 50%, 75% and 100%, of inclusion of Cratylia argentea. The consumption of dry matter (g/day) and live weight percent were 656.47 and 1.76; 743.50 and 1.96; 714.92 and 1.89; and 480.52 and 1.31, of organic matter 619.64; 715.85; 665.36 and 535.85 g/day, and of crude protein 68.01; 108.29; 187.67 and 170.61 g/day. The fiber in neutral detergent consumption in g/day, were 567.44; 536.70; 486.51 and 382.25 g/day. The coefficients of digestibility were 37.87; 24.01; 21.93 and 34.36%, in dry matter basis, and 42.66; 31.54; 27.02 and 36.05%, in organic matter basis, and the crude protein contents were 56.04; 56.64; 68.66 and 71.44%, in 25%, 50%, 75% e 100% on inclusion of Cratylia argentea, respectively. The Cratylia argentea constitute alimentary alternative during the low rainy, with medium digestibility of dry matter, organic matter, crude protein and fibrous fractions, same in blooming, thus presented medium consumption due the tannins. At the level of 50%, possibility greater consumption of dry matter, organic matter, crude protein, grow energy and fibrous fractions.
