Age of head of household averaged 47 years (SD = 14.3). A pre-tested questionnaire was administered to households randomly selected from five districts, Risitu (n=97), Hurungwe (n=56), Gutu (n=77), Gokwe-South (n=104) and Beitbridge (n=37) in eco-zones I-V, respectively.
The objective of this study was to characterise the village chicken farming systems and identify possible threats to, and opportunities for, local chickens in the agro-ecological zones of Zimbabwe. The degree to which village chickens are integrated in the smallholder farming systems differs depending on the socio-economic, cultural and biological factors within each system.

Variation in village chicken production systems among agro-ecological zones of Zimbabwe. The implications of these findings are discussed, including the highly susceptible status of the backyard chickens in Yucatan to NDV and the possibility of this virus being one cause of the syndrome known as mortandad by the local people. This suggests that IBV may be responsible for a large proportion of the respiratory disease observed in backyard chickens in Yucatan. All the villages had chickens that were positive for antibodies to IBV and nine of the villages had chickens that were positive for antibodies to NDV. A seroprevalence survey in 30 villages using haemagglutination inhibition (HI) tests for infectious bronchitis virus (IBV) and NDV antibodies was carried out from December 1997 to June 1998.

The commercial flocks in Yucatan, Mexico are free of Newcastle disease virus (NDV) in its velogenic viscerotropic form, but little is known about the disease status of backyard poultry. Gutierrez-Ruiz, E J Ramirez-Cruz, G T Camara Gamboa, E I Alexander, D J Gough, R E Consideration is given to estimating the offtake from the flock and the financial contribution to the household.Ī serological survey for avian infectious bronchitis virus and Newcastle disease virus antibodies in backyard (free- range) village chickens in Mexico. Respondents describing animal production as their main occupation tended to have greater reliance on chicken sales for their income. The proportion of the flock sold varied between administrative areas (p = 0.025) and occupation of the respondent (p = 0.040). Money from the sale was kept by the owner of the chicken and the money was spent on personal needs. Sales were on demand or when the owner needed money. A majority of chicken sales were from the farm gate, directly to consumers or traders. Respondents generally agreed that chickens could be sold without difficulty. The proportion of chickens sold varied as a result of differences in flock size (p = 0.013), the proportion sold increasing with number of birds in the flock. The proportion of the flock eaten varied between administrative areas (p = 0.009 and p = 0.027), although this was possibly a consequence of differences in consumption patterns between occupation of the respondent, land area cultivated and flock size. Over 80% of respondents kept chickens to supplement their incomes. Nearly all respondents claimed to keep chickens for meat, with a far smaller percentage claiming to keep them for egg production. Answers were provided by 101 men and 99 women. Free- range village chickens on the Accra Plains, Ghana: their contribution to households.Īboe, P A T Boa-Amponsem, K Okantah, S A Dorward, P T Bryant, M JĪ cross-sectional survey investigating the contribution of free- range village chickens to household economies was carried out in four administrative districts within 60 km of Accra.
