Oocyan or blue/green eggshell colour is an autosomal dominant trait found in native chickens (Mapuche fowl) of Chile and in some of their descendants in European and North American modern breeds. We report here the identification of an endogenous avian retroviral (EAV-HP) insertion in oocyan Mapuche fowl and European breeds. Sequencing data reveals 100% retroviral identity between the Mapuche a...

Cross-infection of domestic and wild birds with different parasite species have been known for a long time (Gvozdev et al. 1964, Kasimov 1965). Artamonova (1969) established, that antagonistic relations existed between ascarids and capillarids while synergistic relations between ascarids and coccidia. Lesinsh et al. (1978) concluded that relations between separate helminth species in a mixed in...

The objective of this investigation was to study the histological and histochemical structure of the Harderian gland in native chickens. Samples were obtained from 10 male and 10 female adult healthy native chickens. Tissue sections were stained with haematoxylin eosin, Verhoeff ’s, Masson’s trichrome, alcian blue (pH 2.5), periodic acid-Schiff and Gomori’s method for reticulum. The multilobula...

A .—There is widespread interest in the roles that carotenoids play as yolk and shank pigments, antioxidants, and immune-system regulators in chickens, but nothing is known of such functions in the wild ancestors of chickens—the Red Junglefowl (Gallus gallus). We manipulated carotenoid access in the diet of captive male and female Red Junglefowl to investigate its eff ects on the coloration of ...

Frequent vaccination failures have occurred in the broiler farms in Eurasian countries during Newcastle disease outbreaks. The disease is enzootic in many countries of the region, especially in southwest Asia. I-2 vaccine has been used successfully in village chickens in many Asian and African countries. Our preliminary study showed good efficacy of the vaccine in broiler chickens. Therefore th...

Raillietina species are prevalent in domestic chickens (Gallus gallus domesticus) in Phayao province, northern Thailand. Their infection may cause disease and death, which affects the public health and economic situation in chicken farms. The identification of Raillietina has been based on morphology and molecular analysis. In this study, morphological observations using light (LM) and scanning...

More and more schools are facing the challenge of preserving local community’s culture while preparing the citizens of the “global village”. In this paper we discuss how communityware can support schools in facing this new challenge. In particular, we describe the experience of a school in Venice, Italy, with the adoption of Campiello, a system supporting the exchange of information among commu...

This study examines the sources of geographic variance in commercial Internet use. Until now, two opposing views have been argued on the relationship between Internet technology and economic agglomeration. One view, which we term global village theory, asserts that Internet technology helps lower communication costs and break down geographic boundaries between firms. The other view, labeled urb...
