Flock health monitoring program is an important system, used in the poultry industry worldwide to minimize the production cost, detect clinical and subclinical diseases and acquire data to make comparisons among the farms and identify the future research area. The present study was aimed to investigate the broiler health status through a flock health monitoring program using the lesion scoring ...

Enteric bacterial infections in poultry pose a threat to intestinal health and can contribute to poor feed efficiency and livability of a flock. A variety of enteric bacterial diseases are recognized in poultry. Three of these bacterial diseases, necrotic enteritis, ulcerative enteritis, and spirochetosis, primarily infect the intestine, whereas other bacterial diseases, such as salmonellosis, ...

Recently, performance controlled wireless sensor networks have attracted significant interest with the emergence of mission-critical applications (e.g. health monitoring). Performance control can be carried out by robust congestion control approaches that aim to keep the network operational under varying network conditions. In this study, swarm intelligence is successfully employed to combat co...

Flock health is one of the most critical areas of management that can affect the overall productivity and ultimately the profitability of a flock of sheep. Failure to provide adequate attention to flock health can have disastrous effects on both the welfare of your sheep and your bank account. However, by implementing proper flock health management practices, you can minimize your exposure to p...

Foot-pad dermatitis is a major welfare concern of broilers caused by ammonia irritation from the bedding material. In Denmark, an action plan to control the condition was implemented in 2002 with monitoring through a foot scoring system at slaughter and with predefined limits that trigger sanctions. The objective of the present study was to study time trends and to identify predisposing factors...

Despite continuing research efforts, knowledge of the transmission of the highly pathogenic avian influenza (HPAI) virus still has considerable gaps, which complicates epidemic control. The goal of this research was to develop a model to back-calculate the day HPAI virus is introduced into a flock, based on within-flock mortality data. The back-calculation method was based on a stochastic SEIR ...

salmonella spp. are important food borne pathogens worldwide that frequently infect poultry flocks. this cross-sectional study was conducted to determine the prevalence of salmonella spp. colonization in broiler flocks in shiraz (southern iran) and to find the possible association of infection status with some potential risk factors including vaccination program and use of antibiotics. during o...

Vigilance (scanning) and other behavior patterns were studied in free-ranging Evening Grosbeaks (Coccothraustes vespertinus) at feeders to assess how flock size and flock geometry influenced the behavior of individual birds. The present results indicate that the way in which individual grosbeaks are positioned with respect to one another effects many aspects of their behavior, especially when a...
