Abstract
Chicken feathers, as a slaughter house waste, were processed by NaOH hydrolysis, followed by neutralization with Ha and drying to obtain the hydrolyzed feather meal (HFM) which was used to replace 0% (Treatment) , control ration), 25% (Treatment 2, 25% HFM) or 50% (Treatment 3, 50% HFM) of protein in control ration. A number of 150 Habbard chicks were randomly distributed on 3 groups, to be fed on 3 rations_ At 8 weeks of age ( the end of feeding experiment ) 5 birds of each group were randomly separated and sluaghtered to study the in­fluence of HEM on weight composition, carcass traits and meat composi­tion of broilers. Results were statistically analyzed. Broilers of ration 2 (25% HEM) showed the highest percent of empty carcass, total edible offals and total edible parts , while showed the lowest total inedible parts when compared with ration 1 (0% HFM) or 3 (50% HFM) . The highest percent of meat (% of live weight or % of empty carcass), the highest meat to bone ratio, the lowest percent of bone and the lowest bone to meat ratio were found with 25% HFM treat­ment. Broilers obtained with 50% HFM were statistically of less quality when compared with treatments 2 and 1 . Highest protein and lowest fat
