Effect of sex, age, diseases, and control intervention on chickens’ mortality and its financial implications in Dodoma, Tanzania

The impact of management practices on the disease and mortality rates of broilers and layers kept by small-scale farmers in Dodoma urban district, Tanzania

“…This entails identifying and addressing existing challenges that hinder chicken productivity. In addition, numerous previous studies on chicken diseases in the region [ 19 , 20 , 44 ] provide necessary information for choosing appropriate methods.…”

“…Diseases represent one of the primary constraints on expanding chicken production in Tanzania [ 10 , 17 , 18 ]. Among the most serious infectious diseases affecting chickens are viral and bacterial infections [ 19 ]. In Tanzania, some of the most devastating diseases leading to chicken mortality include Newcastle disease, coccidiosis, fowl typhoid, infectious bursal disease (IBD), and chicken pox [ [19] , [20] , [21] ].…”

In Tanzania, some of the most devastating diseases leading to chicken mortality include Newcastle disease, coccidiosis, fowl typhoid, infectious bursal disease (IBD), and chicken pox [ [19] , [20] , [21] ]. Newcastle disease stands out as particularly severe, capable of wiping out entire village populations [ 20 , 22 ].…”

“…Chicken production holds significant economic importance in arid and semi-arid areas due to its minimal space requirement and potential for enhancing environmental sustainability [ 43 ]. This study was conducted in Dodoma, a semi-arid region in Tanzania, where previous extensive research has been carried out on chicken diseases and mortality [ 17 , 19 , 44 ]. However, limited information exists on the impact of management practices such as sanitation, feeding, vaccination, stocking density, and housing systems, all crucial factors in the intensive production of layers and broilers.…”
