Study on the safety and chemical composition of meat and bone meal

Abstract

This study was conducted in meat processing laboratory at college of Animal Production Science and Technology. The Aims of this study is produce meat and bone meal using dry rendering method. This study was continued for ten month from January to october. Rendered MBM sample were taken for determination of chemical composition and assessment of contamination level and the contaminant organism. The result revealed that chemical composition of meat and bone meal as moisture % as 8.96%, crude protein 46.9 %, fat and ash % were 10.11 % and 26.4 % respectively. The percentage of calcium and phosphorus were 12.30 % and 6 % respectively. The result of samples culturing revealed that the contamination level was 11x10^6, 22x10^6and 28x10^6and the contaminant was E. coli and no salmonella was found.
