Chicken productivity under improved health care and management practices in Dodoma Region, Tanzania

Abstract

Raising chickens is an important activity in many resources constrained households in developing countries, as it is an important source of economic resilience as well as nutrition and food security. Despite its importance, the poultry industry faces many difficulties, including diseases due to low biosecurity and a lack of knowledge on proper management. A cross-sectional questionnaire survey was conducted to study the management practices that influence the performance of chickens in the households raising them in the Dodoma region of Tanzania. The results showed that 89% of respondents were vaccinating their chickens against diseases like Newcastle, fowlpox, infectious bursal disease and salmonellosis. However, many chicken farmers had incorrect information on the vaccination programs, including the frequency of vaccination and the timing of vaccinations, versus the provision of drugs for prophylactic purposes. The results showed that 29.5% of the farmers vaccinated weekly and 63.5% provided prophylactic drugs weekly. Furthermore, raising different types of chickens (OR = 1.45; p<0.01), frequency of vaccinations, (OR = 1.23; p<0.04), larger flocks of chickens (OR = 1.7; p<0.01), small number of chickens per drinker (OR = 1.64; p<0.05) and per feeder (OR = 2.4; p<0.05) were management factors associated with positive chicken performance in terms of growth rate, egg production and weight gain. It is recommended that the farmers are equipped with the necessary information on best management practices like vaccination regimes, prophylaxis timing and proper ratios of chickens per feeder and drinker.
