(Facultad de Ciencias Exactas, Universidad Nacional de La Plata, 2014)En este trabajo se pretende dar respuesta a ciertas cuestiones que permitan aportar conocimientos de impacto para la actividad productiva, en tanto se buscará responder: ¿El deficiente control de Lolium perenne con glifosato ... -
Genetic and management factors affecting beef quality in grazing Hereford steers
(Elsevier, 2012-12)Attributes contributing to differences in beef quality of 206 Hereford steers finished on pasture were assessed. Beef quality traits evaluated were: Warner–Bratzler meat tenderness and muscle and fat color at one and seven ... -
