During outbreaks of highly pathogenic avian influenza in Cambodia, local nongovernmental organizations managed to strategically influence decision making processes in …
Kogi state did not report Highly Pathogenic Avian Influenza (HPAI) during the 2006-2008 outbreaks in Nigeria despite the presence of …
Two experiments were performed to evaluate the protective effect of various vaccination combinations given at 5 and 9 weeks of …
An autologous killed trivalent vaccine (3 x 10 to the power of 8, colony-forming units [CFU]), based on three Salmonella serovars (Typhimurium – serogroup B, Mbandaka – serogroup C, and Orion – serogroup E) prevalent in the flocks of Australian poultry companies, was developed using Salenvac techniques. At 20 weeks, hens vaccinated at 12 and …
Eggs were collected monthly from 12 cage-layer flocks on four farms where Salmonella Enteritidis was present in vaccinated flocks despite …
Fowl typhoid and pullorum disease are two distinct septicaemic diseases largely specific to avian species and caused by Salmonella Gallinarum …
Salmonella enterica in poultry remains a major political issue. S. enterica serovar Enteritidis, particularly, remains a world-wide problem. Control in …
This paper assesses US resident support for mandatory labeling of animal welfare information on pork and egg products and outlines policy considerations for assessment prior to implementing any mandatory labeling policies regarding animal welfare practices. Results suggest consumers support mandatory labeling indicating use of gestation crates (stalls) and laying hen cages. Estimates suggest consumers would …
This study was carried out to evaluate the performance and egg quality of laying hens in their second laying cycle submitted to different forced-moulting methods and three environmental temparatures. Six hundred layers were distributed in a completely randomized experimental design with 15 treatments with five replicates of eight birds each, according to 5×3 factorial arrangement …
Moulting is a natural phenomenon in birds. Temperature variation and photoperiodic changes induce circadian and circannual rhythms, manifested by changes in the neural and endocrine systems, ultimately causing physiological processes resulting in a moult. The concept of induced moulting by feed deprivation arose during the early part of the 20th century as a solution to …
The purpose of this study was to evaluate alternative molting protocols assessing hen welfare and performance during and after molt. Hyline W-36 pullets were housed at 15 wk of age, and their egg production was obtained during this first cycle. When birds were 80 wk, the following molting treatments were applied: a conventional molt consisting …
Dietary molt induction to initiate additional egg laying cycles in commercial laying hen flocks is a wide spread practice in …
The objectives of this study were to evaluate and compare the effects of production, physiology, egg quality, and economics of …
Behaviour in poultry is predominately visually mediated and vision is important to the welfare of poultry. The relationship between vision, behaviour and welfare has primarily been investigated in relation to artificial lighting. Genetically blind chickens provide an alternative experimental paradigm for further investigating the importance of sight. The primary aim of the study was to …
Laying hens usually select an elevated position for resting at night-time. A previous study showed that the position a hen …
