“…The current findings of poultry disease support previous studies conducted in Bangladesh (Uddin et al, 2010;Badruzzaman et al, 2015;Hassan et al, 2016;Rahman et al, 2017Rahman et al, , 2019 and other countries like Nigeria and Pakistan (Balami et al, 2014;Abbas et al, 2015).…”

“…The prevalence of IBD was significantly higher in broiler chickens which agreed with several previous findings Das et al, 2018). The prevalence was higher between the age of 11 and 35 days which is congruent with the earlier published research articles (Chakma, 2015;Islam et al, 2016;Hassan et al, 2016;Rahman et al, 2019). Initial 2 weeks of ages, chicks get maternally derived antibody from mother, after that proper vaccination should be ensured to protect from IBD (Rashid et al, 2013).…”

“…Aspergillosis was found mostly in the early stage of birdlife (1-10) days. Similar findings were also noted in other studies (Badruzzaman et al, 2015;Rahman et al, 2019). The prevalence of aspergillosis higher in earlier age may be due to inhalation of spore from litter, contaminated hatching incubator, higher moisture containing litter and sawdust litter (Sultana et al, 2015).…”

“…The prevalence of colibacillosis, IBD and aspergillosis (Uddin et al, 2010;Choudhary et al, 2012;Hassan et al, 2016;Borah et al, 2017). The difference in disease prevalence between broiler and layer may be due to poor biosecurity management, vaccination failure, improper use of the vaccine, low vaccination success rate, education level of farmers, subclinical disease prevalence and geographical location (Hamid et al, 2017;Rimi et al, 2017;Rahman et al, 2019). In the present investigation, Newcastle disease was found in both broiler and layer chickens but the prevalence was significantly higher in layer chickens.…”

“…Poultry diseases thrive due to several factors such as climate, geographical position, farm hygiene, biosecurity, immunity status, chick quality, hatcheries, and management practices (Abbas et al, 2015;Badruzzaman et al, 2015;Chakma, 2015;Hassan et al, 2016). Along with species of chickens, production type, age and sex play significant role in disease prevalence (Yunus et al, 2009;Rashid et al, 2013;Talukder et al, 2017;Rahman et al, 2019).…”

The present study is aimed at investigating clinical poultry diseases in an Upazila Government Veterinary Hospital of Bangladesh through passive surveillance and to know the frequency distribution of antimicrobial drugs prescription pattern. The study was conducted in Ramu Upazila Government Veterinary Hospital under Cox's Bazar district of Bangladesh from February to March, 2016. A total of 180 cases including 73 broiler, 84 layer, 18 duck and 5 pigeon were included in this study. Diseases were diagnosed based on clinical history, clinical signs, post mortem lesions and rapid kit test. The most prevalent diseases were Newcastle disease (ND) 17.8% (95% CI 12-24%), colibacillosis 11.5% (95% CI 6-17%), infectious bursal disease (IBD) 10.8% (95% CI 6-16%) and aspergillosis 9.6% (95% CI 5-14%) in broiler and layer chickens; duck plague 69.6% (95% CI 49-90%) in duck and pigeon pox 13% (95% CI 0.2-24%) in pigeon. Regarding production type, the prevalence of colibacillosis, IBD and aspergillosis was significantly higher in broiler chickens (17.8, 19.2 and 16.4%) when compared with layer chickens (6.0, 3.6 and 3.6%) (p<0.05). On the contrary, ND and avian influenza (AI) were significantly greater in layer (27.4 and 10.7%) than broiler chickens (6.8 and 1.4%). Within age group, aspergillosis and omphalitis were higher at 1 to 10 days age groups while IBD and ND were greater in older age groups. In layer chickens, the prevalence of ND, AI, salmonellosis and fowl cholera were recorded higher in number between the ages of 9 and 83 weeks. Among the antibiotic drugs, ciprofloxacin (46.7%), colistin (42.2%), trimethoprim and sulphur drug (37.8%) were mostly prescribed to treat the diseases. Poor biosecurity practices and lack of appropriate laboratory diagnostic facilities are associated with these disease distributions in the study area. Strict biosecurity and continuous surveillance program can minimize the disease prevalence.
