Redirected behaviors occur when some course of action is thwarted or inhibited (frustration). They also occur as adjunctive behaviors in operant conditioning tasks, where they might reflect frustration about unrewarded responses. Because frustration is associated with stress, which could interfere with learning and memory, we studied whether the occurrence of redirected behavior is correlated with …
This study reviews all attributes of feed-food competition and enforced-demands of food of animal origin with the aim of delivering …
This paper covers the domestication and distribution of chickens in different parts of the world and describes the global data …
The average mortality for end of lay hens dead on arrival (DOA) was 0.27 per cent (median 0.15 per cent) in a survey of 13.3 million hens transported during 2009. A statistical model of the data indicated main risk factors for DOA to be slaughter plant, distance travelled and external air temperature, with longer journeys …
Appropriate emergency disaster preparedness is a key priority for agricultural agencies to allow effective response to serious avian disease outbreaks. There is a need to develop rapid, humane, and safe depopulation techniques for poultry that are widely applicable across a range of farm settings. Whole barn depopulation with carbon dioxide (CO2) has been investigated as …
1. Poultry on farms are sometimes required to be killed in an emergency, such as during a disease epidemic, yet none of the available methods are ideal. Whole-house carbon dioxide (CO2) administration has practical advantages, but gives rise to welfare concerns. 2. The study measured the body temperature, respiration, cardiac and brain activity (EEG) responses …
In total, 432 thirty-six-week-old laying hens were fed a basal diet supplemented with mannan-oligosaccharide (MOS) or an essential oil mixture …
The attributes of egg production that elicitvalues-based responses include the price and availability of eggs, environmental impacts, food safety or health concerns, and animal welfare. Different social groups have distinct interests regarding the sustainability of egg production that reflect these diverse values. Current scientifically based knowledge about how values and attitudes in these groups can …
Setting directions and goals for animal production systems requires the integration of information achieved through internal and external processes. The …
Continuing population and consumption growth will mean that the global demand for food will increase for at least another 40 …
1. The aim of this work was to select lactic acid bacteria (LAB) strains from chicks and hens of egg-laying …
The reduction of the prevalence of zoonoses and zoonotic agents like campylobacteriosis and salmonellosis requires eradication, control and monitoring measures …
Rodents play a major role in the transmission and maintenance of Salmonella contamination cycles in poultry facilities. However, very limited …
Human salmonellosis cases, particularly those caused by Salmonella Enteritidis, have been closely linked to egg consumption. This epidemiological survey was …
Salmonellosis is one of the most prevalent food borne diseases worldwide. Food animal shave been identified as reservoirs for nontyphoid …
Salmonellosis can be acquired through consumption of infected raw or undercooked eggs. The European Commission has set criteria to control …
A comparison on the prevalence of Salmonella infection in layer hens from commercial layer farms with high and low rodent …
Two trials were conducted to determine B cell changes in Peyer’s Patches (PP) and Cecal Tonsils (CT) of specific-pathogen-free Single …
