“…However, given the monetary constraints placed upon studies in developing countries, this data collection method remains both useful and cost-effective. This is evidenced by similar studies looking at predation of household poultry in the regions (Hoque and Rahman 2004;Hoque et al 2010b;Biswas et al 2006Biswas et al , 2008. Stealing and either maliciously or accidental killing of ducks were not found to be as serious a cause of duck loss as predation and diseases; however, these factors remain a concern.…”

“…Rural duck rearing facilities are owned and managed by women and children and are an important means of reducing poverty for this demographic in resource-poor low-income areas (Pym et al 2002). The predominate limiting factors in poultry production are mortality, untimely sale (such as before laying eggs) and family consumption of ducks (Hoque and Rahman 2004;Biswas et al 2005Biswas et al , 2006Biswas et al , 2008Hoque 2006;Hoque et al 2006Hoque et al , 2010b.…”

Duck rearing is well suited to coastal and lowland areas in Bangladesh. It is an important component of sustainable livelihood strategies for poor rural communities as an additional source of household income. An epidemiological study was conducted during January 2005-June 2006 on 379 households in Chatkhil of the Noakhali District, Bangladesh which were using the recently devised "Bangladesh duck model". The overall objective of the study was to identify factors that significantly contributed to mortality and constrained productivity and to generate sufficient knowledge to enable establishment of a disease surveillance system for household ducks. The overall mortality was 15.0% in Chatkhil, with predation causing a significantly higher mortality compared with diseases (p < 0.001). Common diseases were duck plague and duck cholera. Morbid ducks frequently displayed signs associated with diseases affecting the nervous and digestive systems. Haemorrhagic lesions in various organs and white multiple foci on the liver were frequently observed in dead ducks. Epidemiological analysis with a shared frailty model that accounted for clustering of data by farm was used to estimate the association between survival time and risk factors. The overall mortality rate due to disease was significantly lower in vaccinated than in non-vaccinated ducks in all zones except zone 2 (p < 0.001). Only vaccinated ducks survived in zone 1. In conclusion, duck mortality and untimely sale of ducks appeared to be important constraints for household duck production in Chatkhil. Vaccination against duck plague appears to be an effective preventive strategy in reducing the level of associated duck mortality. A successful network was established amongst farmers and the surveillance team through which dead ducks, with accompanying information, were readily obtained for analysis. Therefore, there is an opportunity for establishing a long-term disease surveillance programme for rural ducks in Chatkhil of the Noakhali District of Bangladesh.

Duck rearing is an important component of sustainable living in poor rural communities, especially as a source of subsistence. A study was conducted on 118 households (N = 1,373 Jinding ducks, Anas platyrhynchus) from December 2002 to February 2004 on Hatia Island in Bangladesh with the aim of identifying the factors that limit the health and production of Jinding ducks. Overall duck mortality was 29.3%, with disease (19.7%) being a more significant factor than predation (9.6%; p = 0.001). Duck mortality also varied significantly among study zones (p < 0.001). Common diseases were duck plague (21.1%) and duck cholera (32.1%). Helminth infection was prevalent, with endemic trematode (Prosthogonimus spp., Trichobilharzia spp., Echinostoma spp.) and nematode (Cyathostoma bronchialis, Amidostomum anseris, Heterakis gallinarum, Capillaria spp., and Echinuria spp.) infections and epidemic cestode infections due to Hymenolepsis setigera. The median egg production rate per duck per household was 93 for a 6-month laying period. The odds of diminished egg production (average ≤ 93 eggs per duck per household for a 6-month laying period) was 25.4 times higher in ducks that were kept in traditional duck houses (p < 0.001) and 14.2 times higher in ducks that experienced delays in the onset of sexual maturity (days 191 and 280; p < 0.001). Ducks that were provided snails for a shorter period of time over the laying period were 18.2 times more likely to produce fewer eggs than their longer fed peers (p = 0.002). In conclusion, duck mortalities due to diseases and predation and parasitic infections appear to be common constraints on household duck production on Hatia Island. Additionally, improving duck housing and providing longer nutritional supplementation with snails increased the production capabilities of household-raised Jinding ducks on Hatia Island.
