OVISO was constituted like a Co-operative of Second Degree on May 4, 1999 in Castuera and it is made up from the following members: ‘Asociación de Lanares de la Serena S. L.’ of Cabeza del Buey (ALANSER), ‘Sociedad Cooperativa Limitada Agrícola Ganadera’ of Castuera and ‘Fomento del Ovino Extremeño S.A.T’ of Villanueva de la Serena (FOVEX), thus forming the greater group of production and commercialisation of ovine in Extremadura, with 350,000 breeding ewes.

At the beginning of 1999, on the grounds of a project conceived by different sectors for a long period of time, OVISO considers that its aim is to be present in the fresh meat market, offering a direct process from producer to retail outlets, which would guarantee a homogeneous product, meeting all safety regulations, its continuity throughout the year, with the well-known quality hallmark in the national and international markets, as it is the lamb of Extremadura.
