[EN] Ammonia, methane, nitrous oxide and carbon dioxide emissions were measured during a
complete production cycle in an enriched cage laying hen facility under Oceanic climate
conditions. Continuous monitoring of gas ...
[EN] Ammonia, methane, nitrous oxide and carbon dioxide were measured during a complete productive
cycle in a laying hen facility under typical Atlantic conditions. Continuous monitoring of gas
concentration, ventilation ...
[EN] Standardized measurement protocols are required to reduce ammonia (NH3) emissions. In vitro measurement of NH3 emissions consists in trapping the emission from an emitting source in an acidic solution under controlled ...
[EN] This PhD Thesis focuses on characterizing potential emissions of ammonia (NH3) and methane (CH4) from pig slurries. In particular, it analyses the relationships between nutrient consumption and excretion, slurry ...
[EN] In those professional activities in which people have contact with animals, employees have a hygienic risk associated with zoonoses, a group of animal diseases which can be transmitted to humans by direct contact with ...
The objective of the present study was to characterise the behaviour of Holstein steers in three different production systems. Forty-eight castrated Holstein males were randomly divided into three groups and allocated to ...
[EN] Poultry production is one of the main livestock related activities in Spain, being the most consumed fresh meat and the second, behind pork, when looking at total (including processed meat) consumption. On the other ...

The design of structures for animal husbandry has energy and environmental implications. Particularly,
the design of broiler houses should consider the comfort of animals in different situations, which is
crucial for ...
[EN] Gas emissions from broiler production have been the subject of intensive research. However, little experimental information exists for farms under the particular management and environmental conditions of the European ...
[EN] There is a need to characterize gas concentrations and emissions from rabbit production. A study was conducted in order to determine ammonia, nitrous oxide and carbon dioxide concentrations and emissions in three ...
[EN] The objective of this work is to characterize two contrasting systems of fattening pigs in Uruguay. A total of 96 pigs (average 41.7 kg) were divided into eight groups of 12 animals, representing two production systems: ...
[EN] Pig slurry is a valuable fertilizer for crop
production but at the same time its management may
pose environmental risks. Slurry samples were collected
from 77 commercial farms of four animal categories
(gestating and ...

The shape of a poultry building and the distribution of its elements (roof, windows distribution, and
window opening) influence the velocity and temperature distribution inside the building and therefore the
thermal ...
[EN] This study covers 5 years of systematic surveys of self-perception of students
about some core skills. The study incudes all students of 3rd year of
Agricultural Engineering (currently Graduate on Agricultural and ...
[ES] El sector porcino es el principal sector en cuanto a producción final ganadera en España. Se trata además de un sector en constante crecimiento y con unas implicaciones ambientales evidentes dadas las emisiones de ...
[ES] El trabajo se basa en el desarrollo de un sistema de alojamiento para cerdas en maternidad o lactación con los lechones hasta el destete buscando una mejora de las condiciones de bienestar de las cerdas, que en los ...
[EN] Data and information management in animal production is critical for a correct operation of a farm. The management software’s are useful tools to facilitate the collection and analysis of information on farms. A program ...
[ES] La reducción de las emisiones de gases de efecto invernadero y amoniaco por parte de la ganadería es uno de los retos de este sector. Para ello, en primer lugar es sustancial conocer, de la forma más precisa posible, ...
