Abstract

The purpose of this study was to determine the physicochemical and functional properties of chicken by-products, including head, feet, intestines and feathers that may be potential sources of animal feed. The chicken wastes are usually not converted into other useful products. Some issues present such as a bad smell, flies and dirt areas that can disrupt the impacts of the community and residents living nearby. The sample preparation was started by collecting samples from the slaughterhouse and stored under a temperature of 3-4 ⁰C before performing the analysis. The findings revealed which the chicken head and feet were higher in the percentage of protein (87.36%) and ash (4.46%) content. The intestines have higher moisture content (83.69%), fat (1.45%) and crude fiber (0.2%). The higher water absorption capacity was intestines (6.03 ml/ g) meanwhile, the feathers have a higher oil absorption capacity (8.36 ml / g) when compared to others. They had been determined the physicochemical and functional properties of chicken by-products and they have potential as a source of animal feed production.
