Causes of loss of Sonali chickens on smallholder households in Bangladesh.

摘要: Abstract In a 1-year-long prospective longitudinal study, we determined the causes of loss ‘Sonali’ (♂ Rhode Island Red × ♀ Fayoumi) chickens at key-rearers’ households smallholder livestock development project-2 (SLDP-2) area in Bangladesh. A key rearer is ‘village poultry-production chain’ (undertaken by SLDP-2 under financial assistance DANIDA) who rears least five Sonali and some ‘Deshi’ (non-descriptive indigenous) their homesteads based on semi-scavenging system. The aim this program to ameliorate poverty, especially among women. Two co-ordination centers (set Potuakhali Noakhali districts) supervised activities. We selected two upazilas (lower administration units) randomly from each districts every upazila, random 125 key-rearer households. Incidence rates disease, predation, selling slaughtering were 0.025, 0.023, 0.081 0.039 per bird-month risk, respectively. major predators study foxes, kind wild cat ( Felis chaus ), mongooses human thieves. Colibacillosis (both single mixed infections) had contributory role death 28% dead birds collected for diagnosis; salmonellosis, Newcastle disease internal parasites contributed next highest (14, 11and 10%) proportional mortalities.
