The ground pods of mesquite (GPM) was submitted to different thermal treatments for two hours after wanted temperature stabilization, for making of the treatments: A = ground pods of mesquite without heat treatment (approximately 30ºC); B = The ground pods of mesquite treated at 60ºC; C = The ground pods of mesquite treated at 80ºC; D = The ground pods of mesquite treated at 100ºC and E = The ground pods of mesquite treated at 120ºC. Soon after, samples were collected for accomplishment for chemical analyses and in vitro digestibility. A completely randomized design with three replications was utilized. The DM, CP, NFE, CF, ADF, celluloses, lignin, ash and CE values, did not were affected (P>0.05) by temperature. It was observed a quadratic effect (P<0.01) on the contents of EE, decreasing linear effect (P<0.01) on the CC and increasing linear effect on the NDF (P<0.01) and Hemicellulose (P<0.05) contents. The in vitro dry matter digestibility and the in vitro organic matter digestibility were not affected (P>0.05) by temperature. On the other hand the in vitro protein digestibility level, showed a quadratic effect (P<0.05), decreasing after 54ºC.
