HEAVY METAL CONCENTRATION AND PROXIMATE ANALYSIS OF SOME SELECTED POULTRY LAYERS FEED PRODUCED IN ADO ODO OTA LOCAL GOVERNMENT

Abstract

Foods including feed of animals are known to be contaminated with heavy metals and other microbial sources originating from their raw materials, water or processes involved in their preparation or formulation. This study focused on assessing the heavy metal concentration, ash content, moisture content and pH of three different feeds sold around Ado Odo Ota Local Government Area of Ogun State, Nigeria. It was observed that the ash contents of the products varies from 13.19% to 35.24%; moisture content ranges from 4.12% to 8.16% while the three feed are of neutral pH value. The heavy metals concentration varies across each sample (Iron 2.644mg/kg to 6.713mg/kg; Lead 0.15mg/kg to 6.7mg/kg; copper 0.00mg/kg; Zinc 0.065mg/kg to 0.572mg/kg; Chromium 0.003mg/kg to 0.127mg/kg and Manganese 1.946mg/kg to 3.113mg/kg). All parameters obtained were below the Federal Agricultural Organization and World Health Organization except that of Lead obtained in Mubat Feed sample coded as C which is 6.7mg/kg which could have deleterious effect on the health status of layers fed with such feed as well that of man upon consumption of such poultry eggs or meat.
