STUDY ON PREVALENCE OF ECTOPARASITES AND ENDOPARASITES OF LAYER POULTRY IN SELECTIVE FARMS OF PATIYA, BOALKHALI AND ANOWARA UPAZILLA IN CHITTAGONG

Abstract

A study was carried out to estimate the prevalence of ecto and endoparasites of chickens of layer farm in three local Upazillas (Patiya, Anowara, Boalkhali) of Chittagong district in Bangladesh. Bulk feces samples from 30 layer farm comprising of about 70,000 birds where 13,000 growers and 57,000 layers were examined during the farm to farm survey for ectoparasites and gastrointestinal worms during the period of December, 2010 to January ,2011. It was conducted by postmortem of dead birds in the farm and laboratory examination of collected feaces samples from different farms and flocks. Qualitative tests were conducted in the Parasitology laboratory of Chittagong Veterinary and Animal Sciences University, Khulshi, Chittagong. Randomly selected birds from a flock were thoroughly examined for external parasites. The farms were free from ectoparasite, that means the prevalence was 0%. The result of the faecal analysis showed that of the 50 fecal samples collected, no sample was positive for helminth egg. 50 chickens was necropsied from different farm for helminth recovery and identification, three birds were positive, representing 6% of the sample population was positive for helminth parasite where one was positive for Raillietina spp. (2%) and two was positive for Ascaridia galli(4%). A total of 3% farm was infested with helminth. Actually this study showed a low prevalence of ectoparasite and helminth infestation due to good farm management and regular deworming
