Study on the Chemical Composition, Nutritive Value and Safety of rendered Animal and Poultry by-products in Khartoum state

Abstract

This study was carried out to investigate the chemical composition, nutritive value and safety of rendered animal and poultry by – products (fifteen) samples of meat meal were collected from different animal and poultry slaughter houses in Khartoum state from January2017 to December,2017 . The samples were rendered (dry rendering method ).and subjected to chemical analysis and cultured for bacterial load and to identify the contaminant organism. Chemical analysis of rendered animal by- products showed that moisture content was 11.56%, fat content was 11.56, protein content was 59.72%, and ash content was 17.39%. The Chemical composition of poultry by – products moisture content was 10.56, fat content was 10.56%, protein content was 65.17%, and ash content was 13.83%. The total bacterial count in rendered animal byproducts ranged from 5.66 x 105 to 5.86 x 105. The total bacterial count in rendered poultry by-products ranged from 4x105 to 5 x 105. The contaminant bacteria in rendered animal and poultry by-products which were characterized according to their morphology and biochemical reaction were salmonella sp. and E .coli SP.
