A major goal of invasion genetics is to determine how establishment histories shape non-native organisms' genotypes and phenotypes. While domesticated species commonly escape cultivation to invade feral habitats, few studies have examined how this process shapes feral gene pools and traits. We collected genomic and phenotypic data from feral chickens (Gallus gallus) on the Hawaiian island of Ka...

Experimental infection of Muscovy ducks with V4 strain of Newcastle disease virus was undertaken to determine the response of the ducks to the virus and the possibility of virus transmission to ducks and chickens in village like conditions. Twelve ducks were randomly and equally divided into three groups of control, inoculated and in-contact. Additionally, the chickens were placed into two grou...

The ground-roosting behaviour of a semi-feral population of domestic hens with broods of chicks was measured in The Gambia, West Africa. Although neither day length nor time of sunset changed significantly over the duration of the study (January-March 1995), mean daily light intensity showed a significant increase. This resulted in an increasingly rapid decline in light intensity at dusk as the...

Background The domestic chicken is an attractive, but underutilized, animal model for studies of adipose tissue biology, metabolism and obesity: 1.) like humans, chickens rely on liver rather than adipose tissue for the majority of de novo lipogenesis; 2.) quantitative trait loci (QTLs) linked to fatness in chickens contain genes implicated in human susceptibility to obesity and diabetes; 3.) c...

BACKGROUND Crossed beaks have been reported to occur in Appenzeller Barthuhn, a local Swiss chicken breed. The assumed causes for this beak deformity which are also seen in other bird species including domestic chickens, range from environmental influences to genetic factors. The aim of this project was to characterize the prevalence, the phenotype, and the underlying genetics of crossed beaks ...

Yunnan is situated in the Southwest China and encompasses regions having high biodiversity, including habitats for several ancestral species of domestic animals such as chicken. Domestic chickens in Yunnan were kept by peoples of varied ethnic and economic backgrounds living in highly varied geographic environments. To identify the genetic background of Yunnan domestic chickens and their relati...

the determination of toxoplasma gondii prevalence in a variety of domestic birds is thought as a good indicator of distribution of t.gondii ooccyts in the environment. to verify the potential role of domestic birds in circulating toxoplasmosis in iran, the present study was conducted in mazandaran provinces, northern iran. latex agglutination test (la) antibodies were found in 25 of 58 free-ran...

Domestic chicken (Gallus domesticus) is one type of poultry that has experienced domestication and spread throughout the archipelago. Chicken consumed by humans should be in a healthy condition free from various types parasites. Information about infected with parasites needed to maintain animal health prevent occurrence zoonotic diseases. Research been carried out on Karang Bongkot Village, La...

Participatory research on vaccination of village poultry against Newcastle disease (ND) was carried out in the village of Disaneng, in the North West Province of South Africa. Three application methods for ND Inkukhu vaccine were shown to induce sufficient levels of immunity in back-yard poultry when correctly administered. These are eye-droplet administration to individual fowls, in-feed and i...

Domestic sea transport is critical to all aspects of life in the Pacific, providing access to markets and health and education services, as well as enabling cultural and social connectivity. Current sea transport services are entirely dependent upon use of increasingly expensive fossil fuels. Whilst there has been increasing research on international shipping, very little focus has been given t...
