We trained chickens to react to an average human female face but not to an average male face (or vice versa). In a subsequent test, the animals showed preferences for faces consistent with human sexual preferences (obtained from university students). This suggests that human preferences arise from general properties of nervous systems, rather than from face-specific adaptations. We discuss this...

An avian influenza (AI) outbreak occurred in meat-type chickens in central Pennsylvania from December 2001 to January 2002. Two broiler breeder flocks were initially infected almost simultaneously in early December. Avian influenza virus (AIV), H7N2 subtype, was isolated from the two premises in our laboratory. The H7N2 isolates were characterized as a low pathogenic strain at the National Vete...

Quality meat-type chickens refer to color-feathered and slow-growing chickens, are developed from local breeds and taste better than fast-growing broilers. Due to the lovely appearance and wonderful taste, quality chickens are considered as alternatives to fast-growing broilers in some regions of the world, such as in Europe and East Asia, and the output of quality chicken meat is rising each y...

A 6-wk feeding study was conducted to evaluate the antioxidative potential, indices such as quality of the thigh meat and liver of broiler chickens fed with a dietary medicinal herb extract mixture (HEM, consisting: Iranian green tea, cinnamon, garlic and chicory at a ratio of 25:15:45:15). A total of 320, one-d-old Ross (male) broiler chickens were used to investigate the effects of 0.0, 2.5, ...

The objective of the present research was to develop vacuum packaging incorporated with Rosmarinus officinalis L. essential oil treatment of fresh chicken breast meat. For this purpose, fresh chicken’s meat breast samples were divided into three groups. First group was kept as a control group with air packaging, others one was with vacuum packaging of samples and last one group was treated with...

To determine susceptibility of chickens, turkeys, and mice to pandemic (H1N1) 2009 virus, we conducted contact exposure and inoculation experiments. We demonstrated that chickens were refractory to infection. However, oculo-oronasally inoculated turkeys and intranasally inoculated mice seroconverted without clinical signs of infection.
