Pancreatic trypsin enzymatic activity in broilers which intake royal palm nut meal Actividad enzimática tripsina pancreática en pollos de ceba que consumen harina de palmiche Martínez-Pérez, Madeleidy Vives Hernández, Yesenia Alberto Vázquez, Maryen Hernández Lemus, Susan K. birds digestive enzyme royal palm fruit aves enzima digestiva fruto de la palma real To study the pancreatic trypsin enzymatic activity in broilers which intake royal palm nut meal, a total of 40 animals (HE21) distributed in a completely random design were used. Four treatments were designed: control and inclusion of 5, 10 and 15 % royal palm nut meal. The animals were weighed and sacrificed at 42 days and the pancreas were extracted, they were weighed and expressed relative to live weight and the trypsin enzymatic activity was determined, which increased with the inclusion of 5 and 10 % compared to the control and 15 % (5744.50 and 5131.50 vs 2415.67 and 1540.67 mg of released tyrosine. min-1. mg-1 of protein, respectively). It is concluded that the inclusion of royal palm nut meal up to 10 % in broilers diets increase the pancreatic trypsin enzymatic activity to digest proteins in the gastrointestinal tract. Para estudiar la actividad enzimática de la tripsina pancreática en pollos de ceba que consumen harina de palmiche, se utilizaron 40 animales (HE21), distribuidos en un diseño completamente aleatorizado. Se diseñaron cuatro tratamientos: control e inclusión de 5, 10 y 15 % de harina de palmiche. Los animales se sacrificaron a los 42 días y se extrajeron los páncreas, se pesaron y expresaron como relativos al peso vivo y se determinó la actividad enzimática de la tripsina, que aumentó con la inclusión de 5 y 10 % respecto al control y 15 % (5744.50 y 5131.50 vs 2415.67 y 1540.67 mg de tirosina liberada. min-1. mg-1 de proteína, respectivamente). Se concluye que la inclusión de hasta 10 % de harina de palmiche en la dieta de pollos de ceba aumenta la actividad de la enzima tripsina pancreática para digerir las proteínas en el tracto gastrointestinal.
