Assessment of heavy metals was carried out to determine the concentrations of copper, cadmium, nickel and lead in chicken feeds obtained from Uyo metropolis, Akwa Ibom State, Nigeria. Three feed types (starter, layer and finisher) of three commercially available brands (X, Y and Z) were purchased from markets in the city. The samples were prepared for analysis by wet digestion method and heavy metals analysis was carried out using an Atomic Absorption Spectrophotometer. The mean concentration of heavy metals (mg/kg) were in dry weight; the levels of copper varied from 5.69 to 26.79 mg/kg and were found to be present in the sequence; Finisher > Starter > Layer. The observed mean values of Cd ranged between 0.18 to 1.47 mg/kg and the levels of Cd in the different brand of feed increase with the trend, Z > Y > X. The mean concentration of nickel ranged from 0.80 - 4.78 mg/kg and the contamination sequence of nickel for the different feeds were Starter> Layer > Finisher, while the levels of lead in the different brands of feed were in the range of 0.00 - 2.4 mg/kg. The observed levels of copper and lead were low in the feed while amongst all the different brands studied, Cd mean values of 1.02 ± 0.73 for Z was slightly above the recommended limit of 1.0 mg/kg. Furthermore, Nickel concentrations were slightly higher in the feed samples analyzed, when compared with the recommended limits. Statistically, it is observed that the Fcrit > Fcal (3.44 > 0.41) for the types of feed, therefore there is no statistically significant difference between the types of feed evidence at α = 0.05, as confirmed by a P value of 0.67. t- test analysis showed that, there was no significant difference in Cd between Y and Z brands as the observed P0.05 was for two samples assuming equal variances were 0.41 and 0.82 for one tail and two tail respectively and the observed P value for two samples assuming unequal variances were 0.42 and 0.84 for one tail and two tail respectively. The heavy metals load in the different types of feeds was found to be at non-toxic concentrations, except for cadmium and nickel. These metal contaminations may arise from environmental factors, production line processes, poor handling and storage by the retailers. The deficiency or the elevation of these heavy metals affects the normal physiological activity and biochemical process of the chicken which in turn affect the health of humans.

“…According to [21], nickel influences Fe absorption and metabolism, and may be an essential component of the haemopoietic process in humans. However, when in excess, it can cause respiratory disease [16].…”

“…Based on the study by Eloma et al [56], which analyzed six potentially toxic elements (PTEs) from poultry feeds such as Cd, Cr, Cu, Pb, Mn, Ni and Zn, four feed forms (starter, grower, finisher and layer) from four producers coded A, B, C and D were sold in Ebony State, Nigeria. The mean concentrations of metals recorded from poultry feeds were as following: Chromium (11.9-7.90 mg/kg); Copper (5.10-7.91 mg/kg); Cadmium (0.49-0.76 mg/kg); Lead (7.17-9.47 mg/kg); Manganese (26.9-34.9 mg/kg); Nickel (3.80-6.50 mg/kg) and Zinc (27.8-38.4 mg/kg).…”

This research was conducted to examine the impact of some essential heavy metals used as a supplement during animal feed formulation and the toxic from unregulated discharges of untreated poultry waste into water bodies on man and aquatic organisms. During the processing of poultry feed, certain heavy metals are used as a supplement such as selenium, copper, zinc, iron etc. to enhance poultry meat and egg yield which is also increase the daily discharge of anthropogenic wastes into our environment that contain high concentration of heavy metals discharges into aquatic environment globally, especially in underdeveloped where this waste are not treated before discharge or used in agriculture as an organic fertilizer in planting crops as a result of this it become absorb by plants and could pose a serious health risk to man and aquatic species as well as affect the ecological balance that can be transfer to humans via the food chain. Some organisms are kills as a result of the toxic heavy metals in water and can affect their growths. Bio-accumulated in the body of certain species, such as fish, which are eaten by humans that causes devastating diseases such as Minamata and Itai-Itai. Regulation of the use some heavy metals as a supplement in feed production or complete removal of it in animal feed should be adopt in order to minimize the human health risks and environmental contamination associated with these animal waste.
