Intestinal samples collected from 43 commercial broiler and 33 commercial turkey flocks from all regions of the United States during 2005 and 2006 were examined for the presence of astrovirus, rotavirus, reovirus, and coronavirus by reverse transcription-polymerase chain reaction (PCR), and for the presence of groups 1 and 2 adenovirus by PCR. Phylogenetic analysis was performed to further char...

BACKGROUND Mitochondrial DNA (mtDNA) hypervariable region (HVR) sequences of prehistoric Polynesian chicken samples reflect dispersal of two haplogroups--D and E--by the settlers of the Pacific. The distribution of these chicken haplogroups has been used as an indicator of human movement. Recent analyses suggested similarities between prehistoric Pacific and South American chicken samples, perh...

This study was conducted to determine the effects of using mechanically deboned chicken meat (MDCM) and collagen on quality characteristics of semi-dried chicken jerky. In experiment I, semi-dried chicken jerky was prepared with the replacement of chicken breast with MDCM (0, 10, 20, and 30%). The pH value of the jerky formulated with only chicken breast was 5.94, while the replacement of chick...

in this study, the pathogenicity of a/ch/it/5093/1999 h7n1 which had been isolated from chicken during the outbreak in italy was assessed in chicken by experimental infection virus. ten spf chickens of four week-old were inoculated with this virus, and five chickens were inoculated with uninfected allantoic fluid. for determination of virus shedding, oropharyngeal and cloacal swabs were taken f...

The development of the turkey and chicken embryo from the first cleavage division through hypoblast formation is described. The early development of the chicken embryo has been categorized into 14 stages. A similar staging sequence for the turkey was not proposed until 1993, when we described the early development of the turkey embryo, which was divided into 11 stages. Comparatively, difference...
