Resumen
An experiment was conducted under tropical dry forest conditions in order to evaluate the storage effect of the multinutrient blocks (BM) on hardness (R), voluntary (CV) and total dry matter intake (CMS), daily gain (GP), feed efficiency (EA) in 20 crossbred of 264 kg of average body weight (PV) in feedlot. The animal’s diet was based in Brachiaria humidicola hay (4.44 % PC) and the suplemmentation with BM. The statistic design was a completely randomized and the experimental unit was an animal, where T0: hay (control), T1: BM 15 days + hay, T2: BM 30 days + hay, T3: BM 45 days + hay. BM (30 x 15 cm) were manufactured in a cilinder molds and carried to the hydraulic concrete testing machine and evaluate resistance in kg/cm2. Increasing storage time affected (P
