Comparative study of indigenous chickens on the basis of their health and performance

摘要: Abstract Three hundred crossbred chickens (at age of 11 wk) were randomly housed in 15 open-sided deep litter pens with 20 each pen under completely randomized design for a period 9 wk. Before evaluating their hematobiochemical and carcass characteristics, the birds provided grower mash ad libitum throughout experimental period. Blood samples taken from genotypic group (nanaff, Nanaff, NanaFf), when 18 20 wk old, respectively, evaluation parameters. At end trial, 3 groups selected slaughtered to determine The findings study revealed that except total cholesterol, spleen, neck weight, there was no significant effect (P > 0.05) on parameters measured. nanaff genotype had significantly higher (P  0.05). Also, assays all within normal range. From health point view, indigenous naked seems superior because its fat cholesterol contents low. Thus, it is strongly recommended should be conscious effort develop commercialize naked-neck frizzled especially developing countries.
