Many factors contribute to the production of safe foods of animal origin. Initiatives for an integrated approach to food safety recognise the importance of optimising transportation conditions to ensure on-farm interventions are preserved. Physical, microbial, and environmental hazards during the transportation process may adversely affect the safety and quality of meat, poultry, and egg produc...
The automatic classification of defective eggs constitutes a fundamental issue of the poultry industry for both economical and sanitary reasons. The early separation of eggs with spots and cracks is a relevant task as the stains can leak while progressing on the conveyor-belts, degrading all the mechanical parts. Present work is focused on the implementation of an artificial vision system for d...
We conducted phylogenetic and epidemiologic analyses to determine sources of outbreaks of highly pathogenic avian influenza virus (HPAIV), subtype H5N1, in poultry holdings in 2007 in Germany, and a suspected incursion of HPAIV into the food chain through contaminated deep-frozen duck carcasses. In summer 2007, HPAIV (H5N1) outbreaks in 3 poultry holdings in Germany were temporally, spatially, ...
Foreign animal diseases (FAD) can cause substantial economic losses in production, consumption, and the supply chain. These are typically highly pathogenic lead to disruptions normal business practices demands for higher investment biosecurity practices. For poultry producers this changes bird pick-ups, chick placements, length of out time on farms as well day-to-day operations. When an FAD is ...
Salmonella enterica serotype Senftenberg (S. Senftenberg) has recently become more frequent in poultry flocks. Moreover some strains have been implicated in severe clinical cases. To explain the causes of this emergence in farm animals, 134 S. Senftenberg isolates from hatcheries, poultry farms and human clinical cases were analyzed. Persistent and non-persistent strains were identified in chic...
In farm animals (bovine, ovine, swine, rabbit and poultry), muscle fibre characteristics play a key role in meat quality. The present review summarises the knowledge on muscle fibre characteristics and ontogenesis in these species. Myofibre ontogenesis begins very early during embryonic life, with the appearance of two or three successive waves of myoblasts which constitute the origin of the di...
