Qualitative Analysis And Assessment Of Heavy Metals In Some Poultry Feeds From Chattogram Division, Bangladesh.

The current study was carried out to determine the quality as well as the concentration of heavy metals in 12 poultry feed samples. Six branded of poultry feeds including starter and grower types were used in this experiment. The qualitative analysis of all samples was revealed that in both starter and grower samples, the protein was obtained in the range of (16.95 � 18.61)% & (16.67 � 18.97)% followed by (88.32 � 90.19)% & (85.00 � 91.32)% for dry matters, (6.55 � 8.09)% & (5.50 � 7.10)% for total ash, (5.50 � 8.09)% for total ash, (2.10 � 3.01)% & (2.03 � 3.32)% for fat, (60.41 � 62.68)% & (58.23 � 64.53)% for carbohydrates and (0.15 � 0.24)% & (0.20 � 0.26)% for acid insoluble ash. The concentration of heavy metals was obtained in various ranges for two types of samples. Starter type of samples were ranges as (
