Duck production plays an important part in the agricultural economy of many Asia countries. The continent alone accounts for 82.6% of the total duck meat produced worldwide. Not only is Asia involved in duck production but also duck meat, eggs and their products are relished and consumed by many Asians. In spite of this, intensive education to empower rural households to increase duck productio...
Punch and pinch skin grafts can be performed readily on the standing horse in the field using basic equipment. Practitioners should utilize these successful grafting techniques to routinely treat granulating equine wounds in order to reduce healing time and create a cosmetic and functional scar. Authors’ addresses: Department of Large Animal Clinical Sciences, Virginia–Maryland Regional College...
Avian bornaviruses (ABV), identified in 2008, infect captive parrots and macaws worldwide. The natural reservoirs of these viruses are unknown. Reverse transcription-PCR (RT-PCR) was used to screen oropharyngeal/cloacal swab and brain samples from wild Canada geese (Branta canadensis) for ABV. Approximately 2.9% of swab samples were positive for bornavirus sequences. Fifty-two percent of brain ...
The aim of this study was to determine the infectious agents isolated from infection - suspected geese sent for the diagnostic examination to National Veterinary Research Institute. The birds were sent from goose flocks localized in different parts of Poland. Totally, 1,013 birds from 122 flocks were examined. The presence of goose parvovirus (GPV), goose haemorrhagic polyomavirus (GHPV), and g...
Heritage conservation is an important recurring research theme on agricultural heritage systems. Improving the income of farmers from agriculture is regarded as an effective conservation approach. This study examined how the improved rice-fish-duck coculture (IRFDC) promotes the protection of the Honghe Hani Rice Terraced System (HHRTS) by keeping farmers farming in their hometowns. A semi-stru...
This work was aimed to study the preparation and hydrolyzation of cartilage from duck trachea to obtain crude chondrotin sulfate(CS). Duck trachea is comprised of 66.19 ± 0.96% protein and 3.46 ± 0.15% CS (dry basis). HPLC chromatograms revealed that CS of duck trachea contained higher content of ΔDi-4S than ΔDi-6S with trace amount of ΔDi-diSs. To obtain cartilage part of the trachea, use of a...
In this paper I reflect on the role of HCI Education in University level courses. The theme of the conference is 'Architecting the Future' and I analyse what we mean by this in terms of HCI Education. As a community we seem to have moved from fundamental HCI issues through usability and user-centered design, and last year were all about design and creativity – have we moved one step beyond agai...
The ventilatory response to hypoxia appears to be controlled largely by carotid body chemoreceptors in birds, as it is in mammals, and the stimulus to these chemoreceptors is probably the partial pressure of oxygen in the arterial blood (Bouverot, 1978; Bouverot, Douguet & Sebert, 1979). There are, however, interspecific differences in the threshold arterial Po2 stimulating the hypoxic ventilat...
The MHC class I gene was amplified, cloned and sequenced in guinea fowl using the primers specific to BF2 gene in chicken. The nucleotide sequence of 571 bp partial CDS of BF2 gene includes 32 nucleotides of signal peptide (exon 1), complete " domain (270 nucleotides) and 269 nucleotides of " 1 2 domain. For " and " domain no sequence variation was observed within guinea fowl sequences, however...
Active serologic surveillance is necessary to control the spread of the avian influenza virus (AIV). In this study, we evaluated a commercially-available cELISA in terms of its ability to detect AIV antibodies in the sera of 3,358 animals from twelve species. cELISA detected antibodies against reference H1- through H15-subtype AIV strains without cross reactivity. Furthermore, the cELISA was ab...
