Galvão, Lurdes; Guedes, C.M.; Rodrigues, M.A.M.; Silva, S.R.; Valentim, Ramiro; Moreira, Olga; Ribeiro, José Ramalho; Sequeira, C.A.In the Northeast region of Portugal hays from natural pastures are traditionally used as the main feed during the period of drought and the evaluation of its nutritive value is essential. The aim of this study was to predict the apparent organic matter digestibility (OMD) of 21 hays from natural pastures based on chemical composition, pepsin-cellulase solubility of organic matter (OMS) and in vitro organic matt...

Galvão, Lurdes; Moreira, Olga; Bessa, Rui; Alves, S.P.; Sousa, Fernando Ruivo de; Ribeiro, José Ramalho; Alves, VirgílioThe objective of this study was to evaluate chemical parameters related to meat quality, contributing to a better characterization of “Carne Mirandesa-PDO” veal. This study was made in three farms, from the Northeast region of Portugal (PG, FA1 and FA2), where calves were raised permanently indoors, nurse from their dams overnight, and fed with hay and concentrate made with local ingredients and soybean meal.
