    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.

    Surveys were conducted to 141 farmers registered in the FERPAM at Asturias (A), Cantabria (C) and Castilla and Leon (CL) regions, with the aim to know animal production system characteristics. Racial diversity was high (57.4% of the cows are "Parda de Montaña" (PM) and the 25.2% are cross with other breeds) and only 24.1% of farms have PM pure-breed animals. The average herd size was 32.1 cows in A, 35.3 in C and 64.6 in CL. The 95% of farms are located in mountain areas. The animals are kept indoors 3.7 months/year, as average. The average age of calves weaning was 5.8 months.
