Resumen : The significance of major environmental factors affecting Gestation Length (GL) in the Asturiana de los Valles beef cattle breed and the influence of GL on birth weight and calving ease have been analysed. The degree of muscularity of the calf at birth significantly affects GL: culard calves lengthened GL by more than 1 day with regards to normal calves; however, the way in which the degree of muscularity of dams affects GL is not clear; normally muscled dams seem to show a slightly longer GL than that of dams expressing some degree of muscular hypertrophy. Birth weight and calving ease increase 0.180 kg and 0.013 points respectively per day of GL.
