The research was conducted to study the effect of heat stress on blood parameters in indigenous sheep. Nine sheep were divided into three groups which were almost similar in age, sex and weight. Three groups were divided as zero hour (T0), four hours (T4) and eight hours (T8) heat exposure to direct sunlight. During experimental period temperaturehumidity index (THI) value was calculated as 27.09 which indicate T4 and T8 groups were subjected to heat stress condition for at least four hours and eight hours respectively every day. The amount of red blood cell (RBC), hemoglobin (Hb%) and packed cell volume (PCV%) were increased significantly (p<0.05) with the increase of heat stress but the amount of white blood cell (WBC) had no significant difference (P>0.05) among the treatment groups. It can be concluded that heat stress had significant changes on some blood parameters in indigenous sheep. DOI: http://dx.doi.org/10.3329/jbau.v12i1.21253 J. Bangladesh Agril.

Livestock keeping at urbanized areas is increasing folds in rate now-a-days in Bangladesh. To characterize the urban livestock keeping practices and its implications on public health and environmental issues in Mymensingh, Gazipur and Shariatpur municipality, Bangladesh, a questionnaire survey was carried out. Ninety livestock keepers were freely characterized and data were obtained Disease outbreaks are 21%, 18%, 17%, 16%, 13%, and 10% of ecto-parasite, mastitis, helminthosis, lumpy skin disease, wounds, and diarrhoea. 14% livestock owner follow vaccination program to keep better their animals from viral or bacterial infections. All the respondents (100%) are aware that livestock keeping could have a negative effect on urban health and environment. More than 50% of the respondents choose dung and urine disposal, malodor and blocked roads are the major damages caused by livestock. Strategies for controlling the damages were as follows: awareness through broadcasting documentary via mass media (4.33), regular health check via veterinary services (3.96), keeping database and regular updated of livestock keepers (3.82), proper disposal of waste (3.69), strengthening rules and policy development for local authority (3.61), reducing numbers of animal (3.48), provision of extension services (3.47), cleaning vicinity daily (3.32). There were some measures taken from public interviewing which need to amend for keeping health and environment free from diseases and pollution.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
