La presencia de la formación en Agroecología en la Universidad ha mejorado notablemente en los 30 años transcurridos desde el inicio, pero sigue siendo muy escasa. Su carácter transversal, el enfoque productivista de las ciencias agrarias y el desconocimiento de lo que la Agroecología aporta a los sistemas agroalimentarios han sido las...

Han sido muchos los métodos propuestos para contrarrestar los efectos negativos del calor en el ganado vacuno lechero. En condiciones severas de estrés, la utilización de agua para mojar al animal y su posterior evaporación ha resultado muy efectiva. En el presente trabajo se estudia la posibilidad de reducir lo síntomas de estrés por calor,...

El ganado caprino es una de las especies ganaderas más importantes del medio rural, ya que tradicionalmente se ha desarrollado en zonas en un porcentaje elevado marginales, en las que este tipo de ganado constituía una forma de aprovechamiento rentable, contribuyendo además a fijar población. Sin embargo, la evolución en los últimos diez años...

The main objective of this study was to analyze the carbon footprint (CF) of grazing dairy goat systems in a natural park according to their grazing level. A total of 16 representative grazing goat farms in southern Spain were selected and grouped into three farming systems: low productivity grazing farms (LPG), more intensified grazing farms...

Payoya es una raza caprina andaluza de aptitud lechera que actualmente se encuentra en peligro de extinción. Se ubica, principalmente, en la Sierra de Cádiz y la Serranía de Ronda (Málaga) y se explota en sistemas semiextensivos o semiintensivos donde el pasto natural y en ocasiones cultivado, constituyen la base de su alimentación. En este...

The small ruminant livestock sector faces the challenge of reducing greenhouse gas (GHG) emissions. Carbon footprint (CF) studies on dairy goats, the most widely used indicator to quantify the impact of livestock farming on global warming, are still few. The aim of this study was to calculate the CF of the different production systems of...

RESUME – "Utilisation d'indicateurs pour évaluer la durabilité des systèmes de production animale". Les indicateurs permettant de caractériser la durabilité des systèmes de production animale sont peu développés. L'évaluation de la durabilité de ces systèmes doit être dynamique et multidisciplinaire et les indicateurs utilisés doivent permettre...

Exploring and developing new tools for the accounting and management of natural C sinks will provide a closer, more accurate option to remark the importance of such sinks in relation to livestock production, helping to support the persistence of some seriously endangered traditional, environmentally sustainable livestock farming. Following both...

Traditional meat goat farming systems are characterized by rearing autochthonous breeds and using natural resources through grazing, often within protected natural areas. In a context of reduction of the number of farms, due to the low income derived from the sale of kids, the role of those systems as suppliers of presently non-remunerated...

This paper presents a methodological proposal of new energy sustainability indicators according to a novel accounting that follows agroecological and ecological economics criteria. Energy output is reformulated to include manure and thus consider the contribution to fertilization made by pastoral livestock farming to agroecosystems. Energy...

The aim of this paper is to develop a new specific algorithm (fat- and protein-corrected milk calculation) for dairy goat to be used in life-cycle assessment (LCA) studies. Though the contribution of goat milk to world milk production ranks third, the literature does not report any specific correction for goat's milk. Using the available...

Perú tiene un importante sector caprino con rebaños de aptitud cárnica o mixta. Sin embargo, en los valles de la costa central hay una mayor tendencia a la orientación lechera, alimentando a los animales en base a rastrojos agrícolas. El objetivo de este estudio fue caracterizar las explotaciones de esta zona, para lo cual se entrevistaron 60...

In the Mediterranean Basin, sheep meat production systems are based on grazing, and help to conserve biodiversity, mitigate the greenhouse gases emissions and maintain the population in rural areas. However, the lack of differentiation of pastoral systems, as opposed to the intensive model, puts its continuity at risk. In this sense, organic...

Organic farming conserves natural resources, promotes biodiversity, guarantees animal welfare and obtains healthy products from raw materials through natural processes. In order to evaluate possibilities of increasing organic animal production, this study proposes a farm-scale multicriteria method for assessing the conversion of dairy goat...
