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.
