The objectives of this study were to determine the morpho-biometric characteristics of Vietnamese indigenous Ho chicken breed and to evaluate its production, reproduction performance and egg quality. The study was carried out on 20 households raising purebred Ho chicken from September 2013 to April 2015 in Northern Vietnam. Morpho-biometric characterization was based on measurement of 128 adult individuals. The egg production was observed on 66 hens within 20 households. A total of 29 eggs were freshly collected from 8 hens at the 20th laying week for quality analysis. Ho chicken breed is a breed with a large dimension, a large diversity in the colors (black with gold hackle, black copper, wheat, tan and tricolor), a heavy weight 3.78 and 2.64 for adult males and females, respectively), a low egg production (12.73 eggs/clutch) and a relatively low rate of embryo eggs (72.81%). A research to improve the egg production and reproduction should be undertaken to obtain a better performance, economic efficiency while maintaining this genetic heritage and sustaining the biodiversity of the avian breeds in Vietnam.

This study was conducted to provide informations of the growth performance of Dong Tao chicken raising under household conditions in Dong Tao commune, Khoai Chau district, Hung Yen province. A total of 250 Dong Tao chickens were observed from 1 day old to 24 weeks old among 5 families with following traits: body weight, relative growth rate, average daily gain, survival rate, feed intake and feed conversion rate. Dong Tao is one of the native chicken breeds with a heavy weight. The body weights of the cock and hen were 2.6 kg and 2.2 kg respectively at 24 weeks old. The average daily gain increased gradually from the first weeks old, peaking and stability in the period to 10 weeks old (21.24g and 20.26g for cock and hen respectively) then it began to decline from the weeks old thereafter. Whereas the relative growth rate decreased gradually by weeks old. Feed conversion rate was 4,38kg based on the whole growth period. These results could be used to dertermine the characteristics of this purebred breed which would contribute to conserve and develop in a sustainable way. [less ▲]

In order to evaluate the economic efficiency and production status of Ho chicken, this survey was carried out on 34 households raising Ho chickens in Thuan Thanh district, Bac Ninh province, from December 2012 to April 2013. Morpho-biometric characteristics were measured on 181 individuals (46 cocks and 135 hens) according to FAO standards. The results show that Ho chicken herd size is very limited, with 30.78 chickens per household. Average age at the first laying is rather late (7.42 months) with 11.97 eggs in a laying cycle and 76.32% of hatchability rate. These numbers are low because Ho chickens are heavy and clumsy, and therefore could easily step on and break their eggs. The body weight of a cock is 3.79 kg at 9 months while the hen weight is 2.63kg at 12 months. The body length, neck length, back length, thigh length of cock are significantly higher than those of hens (P<0.05). Production of these chickens does not require much initial investment costs. In these costs, buy breed and chicken housing are the most important in the fixed costs. The average annual expense to operate Ho chicken production reaches 12.16 million VND (565.58 USD) while the average annual revenue is 30.85 million VND (1443 USD). [less ▲]

The need to set up efficient and sustainable surveillance networks is a major concern which must be continually placed at the heart of the overall issue of development. In developing countries, the political priority to reduce poverty means that it is vital to include social aspects in public decision making on health management in general. This focus on social aspects can be considered all the more important regarding surveillance as it is deeply embedded in agents’ everyday life. The flow of information about animal health involves different non-monetary costs, ensuing from stigmatization or from social pressure to withhold or disclose information. Understanding, measuring and alleviating these social costs of information is required to ensure the effectiveness and viability of surveillance. The present study considers the case of highly pathogenic avian influenza surveillance in Vietnam. It aims at establishing a protocol allowing for understanding and quantifying social costs incurred by surveillance agents at the community level. In this prospect, tools and concepts from anthropology, participative epidemiology and experimental economics were combined. More particularly, social network analysis, participatory observation, companion modeling and stated preference surveys were applied for the thorough examination of constraints and costs of health information flows. The opportunity for the scaling-up of such methodologies and for the inclusion of the so-elicited quantitative values in socio-economic evaluation of surveillance systems are discussed. [less ▲]
