| 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 | ||
