Abstract:
... The poultry red mite (PRM), Dermanyssus gallinae, is an ectoparasite of great importance related to poultry farms worldwide. Problems associated with its control have led to the search for alternative treatments, especially using inert dust, which has recently been introduced into liquid formulations. Therefore, the objective of this work was to evaluate the acaricidal activity of a liquid diatoma ...

Abstract:
... Ammonia and carbon dioxide are the most relevant among the harmful gases present in broiler houses and their effects on animal health depend on concentration and exposure time. Inside these houses, increasing ventilation is the most common strategy adopted to control the concentration of these gases. This strategy is effective but increases electrical energy consumption (for fan operation) and the ...
