Accurate monitoring of ammonia has decisive significance for the environmental control of poultry housing. Existing sensors based on semiconductor or electrochemistry have the defects of short life, severe baseline drift and delayed response when facing the harsh environment of poultry housing. In this work, we developed a portable sensor based on ...

Consumer concerns about animal welfare have prompted egg producers to dabble into alternative systems. This review aimed to describe the feeding practices and animal welfare of laying hens in systems with access to pastures, as well as forage management and production costs. Eighty-seven scientific manuscripts were consulted in databases and were c...

This study is part of a 2 year disease surveillance project conducted to establish the prevalence of poultry and zoonotic pathogens, including Campylobacter spp., among small poultry flocks in Ontario, Canada. For each post-mortem submission to the Animal Health Laboratory, a pooled sample of cecal tissue was cultured for Campylobacter spp., and a ...

Plumage damage represents one of the animal-based measures of laying hens welfare. Damage occurs predominantly due to age, environment and damaging pecking. IR thermography, due to its non-invasiveness, objectivity and repeatability is a promising alternative to feather damage scoring systems such as the system included in the Welfare Quality ® ass...

Pest and diseases in agricultural systems reduce the yield and quality of available food and feed worldwide. To meet the global growing demand for these products, losses should be reduced, preferably in a sustainable way. Integrated Pest Management (IPM) is a sustainable method that aims to minimize economic losses due to pests and diseases. IPM is...

De vorming van ammoniak uit het strooisel in vleeskuikenstallen is afhankelijk van verschillende factoren zoals het klimaat (zowel in als buiten de stal), het drogestofgehalte van de uitgescheiden mest, en het drogestofgehalte, het ammoniumgehalte, de pH en de temperatuur van het strooisel. Het is echter niet bekend hoe deze processen onderling op ...
