The process of agricultural abandonment has been taking place for the last decades all around Europe. This process has special effect on mountain livestock farming, as it is the case of that of Catalan Pyrenees, which is characterised by an extensive management of the herd between the alpine grasslands in summer and the hay meadow of the lower valleys in winter. The process of agricultural abandonment, apart from the obvious closing down of the exploitations, also implies a gradual decrease of the management intensity of the farming exploitation.

La dehesa es un ecosistema agroforestal único que aúna un óptimo rendimiento económico con una menor incidencia en el medio. En la Península Ibérica hay unas 500.000 hectáreas de dehesas concentradas en Andalucía, Castilla y León, Extremadura, Castilla La Mancha y Madrid. Las razas autóctonas son las que, por su rusticidad y adaptación, mejor aprovechan y conservan la dehesa.

The Celta pig breed was the most important in Galicia (northwest of Spain) until beginning of the 20th century, suffering from this moment a continuous decrease caused by the introduction of improved breeds and their crosses. For this study 19 Celta pig breed from Santiaguesa genotype and 15 from Carballina genotype were used. Animals were weighted once at month during 12 months. To Santiaguesa genotype not significant differences (P>0.05) were observed until 198 days but it has been detected significant differences (P0.05) in any growth curve between gender.

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. Raza de doble actitud carnicera y lechera, su explotación se halla orientada mayoritariamente a la producción de carne, si bien los escasos rebaños inscritos en el libro genealógico se hallan dedicados a la producción lechera.

La denominada "vaca Monchina" raza en peligro de extinción se encuentra distribuida en la Comunidad Autónoma de Cantabria y zonas limítrofes. En ella se engloban un conjunto de animales que manifiestan variabilidad según la capa: Morena (Castaña y Avellana), Marina y Barrida, contando además con un censo muy reducido de animales y con un porcentaje de hibridación con otras razas variable, lo que dada la variabilidad antes aludida hace en ocasiones difícil la asignación de un individuo a la raza.
