A study was carried out at the IRD-SELVA-TARAPOTO, Region San Martin Fundo Pucayu, pertaining to a life zona clasified as Tropical Dry Forest. The research aimed to evaluate the use of Stylosanthes guianensis as a protein bank and its impact on weight gain of suckling calves grazing Panicum maximum (Mombasa). Two treatments were applied; control group grazing only Mombasa and the experimental group grazing Mombasa with access to protein bank for one hour a day. The parameters evaluated were: a) forage availability; b) chemical composition of the diet; c) ingestive behavior and d) calf weight gain, under a design completely randomized statistical design. The results revealed: a) forage availability of dry matter (DM): Mombasa 3,878 and Stylo 2,210 kg/DM/hectare b) chemical composition of the diet crude protein (PC), neutral detergent fiber (NDF), acid detergent fiber (FDA), for Mombasa 7.46%, 68.59, %, 36.88% vs. Stylo + Mombasa 7.86%, 64.92%, 35.73%, respectively. No significant differences (p<0.05) were found for (PC) and (FDA), there are significant differences (p<0.05) for (NDF) between the treatments. Diet in vitro digestibility (IVDMS) for Mombasa 60.17% vs Stylo + Mombasa 61.07%; there are no significant differences (p<0.05) for (DIVDMS) and the Forage Relative Value Index (VRF) for Mombasa 81.63% vs Stylo + Mombasa 87.57. c) ingestive behavior: dry matter intake (% live weight) for Mombasa 1.75% vs Stylo + Mombasa 1.85%, (number of bites/minutes, bite weight g/bite, time of grazing/hours and rumination time/hours) without access to protein bank only to Mombasa15.05, 0.32, 7.72 and 1.22 vs. with access to the Stylo + Mombasa protein bank 15.49, 0.33, 7.69 and 0.95 respectively. d) weight gain: control group 271 g/d vs supplemented group with protein bank 293 g/d; there are no statistical differences (p<0.05) for ingestive behavior and weight gain between treatments. It was concluded that supplementation with a protein bank of Stylo remarkably improves diet quality and forage intake. Further research is recommended in the use of protein banks to improve the diet quality of calves grazing pastures dominated by grasses.
