Experimental studies on gas and dust emissions to the atmosphere in rabbit and broiler buildings.

Calvet Sanz, Salvador (2010-05-24)

La contaminación atmosférica originada por la producción animal intensiva afecta al medio ambiente global, a la salud de las personas y al bienestar de los animales de la propia granja. Se trata de una problemática de ...
Factors affecting CH4 and NH3 emissions from pig slurry in commercial farms

Fernández Ochando, Álvaro (2014-02-04)

[ES] Hoy en día cada vez hay más preocupación sobre los posibles efectos medioambientales provocados por la ganadería. La ganadería es una importante fuente de gases contaminantes a la atmósfera como el amoníaco (NH3) y ...
Impacto del nivel de grasa y su interacción con la fibra sobre las emisiones de amoniaco y metano en purines de cerdos de cebo

Flores Gil, Viviana Nathalie (2016-07-19)

[EN] Nutritional strategies in pig production are of utmost relevance in the reduction of the impact on the environment. The objective of this study was to assess the effect of the inclusion of an unreliable source of ...
Low frequency aeration of pig slurry affects slurry characteristics and emissions of greenhouse gases and ammonia

Calvet, S.; Hunt, J.; Misselbrook, T. (Elsevier, 2017)

[EN] Low frequency aeration of slurries may reduce ammonia (NH3) and methane (CH4) emissions without increasing nitrous oxide (N2O) emissions. The aim of this study was to quantify this potential reduction and to establish ...
Modificación de la calidad del nitrógeno en dietas para cerdos de engorde: efectos sobre los parámetros productivos y las emisiones de amoniaco del purín

García Miralles, Hugo (2014-06-09)

[ES] Se evaluaron los efectos de 3 dietas de igual valor nutricional en cerdos de cebo, modificando los ingredientes, y por tanto el aporte de nitrógeno ligado a fibra de la ración y la fuente proteica, sobre los parámetros ...
