Experiment 1. The aim was to evaluate intake, apparent digestibility, physical effectiveness NDF, nitrogen balance, microbial protein synthesis, chewing activity, performance, carcass characteristics, and blood parameters of crossbreed x Santa Ines lambs fed increasing levels (0, 5, 10, and 15 % DM basis of the diets) of ground licuri. Forty male lambs (20,89 kg ± 3,97 BW kg) were used in a complete randomized design. The experiment lasted 75 days. The lambs were fed a mixture of Tifton hay (29 %), sisal silage by-products (17 %) and a concentrated mixture (54 %), with 46:54 forage: concentrate rates. The performance was recorded (kg) every 25 days, and the digestibility data were collected between 41 and 45 days. The animals were fed twice daily, at 8:00 h and 16:00 h, ensuring a 10% surplus and water supply was ad libitum, and significance was declared at P≤0.05 for both experiments. The licuri inclusion showed decreased linear effects (P0.05). The MPS and EMPS were affected negatively (P0.05). The MPS, total weight gain, and carcass characteristics decreased linearly (P0.05) and NDF (g) per bolus decreased linearly (P0.05) nutrient intake, nutrient digestibility, rumen fermentation parameters, nitrogen balance, MPS, EMPS, and blood parameters. The pH and concentration of NH3-N, acetate, propionate, butyrate, and total VFA, showed quadratic effect (P0.05) on the treatments x time interactions of the rumen fermentation parameters. The ground licuri inclusion increased the NDF, EE, and decreased NFC as was included in the diets. The animals responses in these experiments were contradictory and therefore required subsequent studies with NDF adjustments in the diet to determine the appropriate level of ground licuri inclusion.
