8 flocks of Ojinegra ewes (n=5634) were studied during a productive cycle (2007-2008) in Teruel (Spain), a low-mountain dry and harsh area. Ojinegra ewes belong to a local breed, of small-medium size, reared under a semi-extensive system of management. Throughout three seasons (autumn, winter and spring) weight and BCS of 5634 ewes at lambing and weaning were recorded and 5786 lambs were weighed fortnightly form birth to weaning. Season had a significant (p>0.01) effect on weight and BCS of ewes and on lambs average daily gain.
After a previous description of pasture utilization in Sierra de Guara Natural Park, eight sheep farms were selected for a study of the relationships between farming systems and land use at the farm level. They were representative cases obtained from a previous typology based on criteria of technical management and pasture use. After a detailed description of the system, a SWOT analysis was carried out in order to identify the main factors involved in farm continuity and sustainability of land use.
Land degradation is a major challenge limiting crop production in Ethiopia. Integrated soil and water conservation is widely applied as a means to reverse the trend and increase productivity. This study investigated the effects of such integrated approaches at two sites, Jeldu and Diga, in Western Ethiopia. A split plot design with physical soil and water conservation in the main plots and agronomic practices in the sub plots was employed.
La raza Castellana se halla distribuida por distintas áreas de la Comunidad de Castilla y León, si bien la mayor parte de su censo se encuentra en comarcas del oeste de la provincia de Zamora.
