The term biotechnology has been defined as the application of biological organisms, systems or processes to manufacture and service industries (Anon, 1980) and is, therefore, more than the application of ‘genetic engineering’ techniques alone. The potential application of biotechnology to the agricultural livestock industry includes many wide ranging areas: animal health; breeding; livestock production; livestock nutrition and the nutritive value of feeds. The role of biotechnology in animal nutrition and feeding is of particular importance since feed costs account for a significant proportion of the total variable costs in any livestock production system (e.g. milk, meat). The potential implications of biotechnology in animal nutrition has been reviewed by Armstrong (1986) and includes references to the improvement of the nutritive value of feeds through, for example, genetic manipulation of feed sources (cereals), appropriate supplementation and the use of biological inoculants with or without enzymes as silage additives and to improvements in the ability of the animal to obtain nutrients from feeds through the addition of enzymes to feeds and modification of rumen microbes through genetic engineering.

In recent times we have allegedly witnessed a “post-truth” turn in society. Nonetheless, surveys show that science holds a relatively strong position among lay publics, and case studies suggest that science is part of their online discussions about environmental issues on social media — an important, yet strikingly under-researched, debate forum. Guided by social representation theory, this study aims to contribute knowledge about the role of science in everyday representations of livestock production on social media. The analysis identifies two central themata, namely lay publics' contestations of (1) facts and non-facts, and (2) factual and non-factual sources.

The objective of this opinion is to reflect the role of silvopastoral systems (SPS) in Costa Rica's Low Carbon Livestock Strategy (EGBC, for its acronym in Spanish), and how these sustainable and extensive integrated livestock production function as a model, and how the woody component is integrated in the system, contributing to the reduction of greenhouse gases favoring the mitigation of climate change. Applying relevance to the purpose, this revision refers to the integration of forestry activity in livestock production, as a viable alternative of its production system. Based on SPS criteria from which a tree component (natural or established) is associated with an herbaceous community (natural or improved pastures) and a farming component (livestock) in the same site, where biological interactions exist among components, and land use is maximized. This essay also clarifies how SPS are grouped striving to be fair-minded in evaluating the economic, productive, social, and environmental points of view, and the effects of the interaction among its components. Therefore, this analysis applies significance to the interpretation of the SPS relation among biology, society, and culture, and its role in Costa Rica's Low Carbon Livestock Strategy.   El objetivo de este dictamen es reflejar el papel de los sistemas silvopastoriles (SPS) en la Estrategia de Ganadería Baja en Carbono (EGBC) de Costa Rica, y cómo funcionan como modelo estas producciones ganaderas integradas, sostenibles y extensivas, y cómo se integra el componente leñoso en el sistema, contribuyendo a la reducción de gases de efecto invernadero favoreciendo la mitigación del cambio climático. Aplicando la relevancia al propósito, esta revisión se refiere a la integración de la actividad forestal en la producción ganadera, como una alternativa viable de su sistema de producción. Con base en los criterios de SPS a partir de los cuales se asocia un componente arbóreo (natural o establecido) con una comunidad herbácea (pastos naturales o mejorados) y un componente agrícola (ganadería) en un mismo sitio, donde existen interacciones biológicas entre los componentes, y se maximiza el uso de la tierra. Este ensayo también aclara cómo se agrupan los SPS tratando de ser justos en la evaluación de los puntos de vista económico, productivo, social y ambiental, y los efectos de la interacción entre sus componentes. Por lo tanto, este análisis aplica la importancia de la interpretación de la relación de los SPS entre la biología, la sociedad y la cultura, y su papel en la Estrategia de Ganadería Baja en Carbono de Costa Rica.
