“…Previous studies by Mahesar et al [35], Zhang et al [27], Mohammad et al [26] and Imran et al [36] reported higher Cd concentrations in the ranges of 3.8 -33.8 mg/kg, ND -8.00 mg/kg, 3.33 -16.67 mg/kg and 0.11 -1.41 mg/kg respectively. In Suleiman et al [37] a low cadmium content of 0.01 -0.55 μg/ml which is similar to the values obtained in this study was reported in feeds. Cadmium mimics other divalent metals that are necessary for a variety of biological processes but has no recognized biological function in humans or animals [41,42].…”

“…This value is lower than the ranges of 23.2 -32.6 mg/kg, 1.10 -7.85 mg/kg and 2.33 -7.90 ppm obtained by Mahesar et al [35], Okoye et al [28] and Imran et al [36] respectively. On the contrary, Suleiman et al [37] reported lower lead contents in poultry feeds. The concentration of Pb in the feed sample is below the 5 mg/kg maximum permissible limit in feeds by FAO/WHO [38].…”

“…The concentrations of Ni obtained in this study were generally higher than 0.5 mg/kg maximum permissible limit in feed by FAO/WHO [43] and WHO [44]. Several studies have reported nickel in feed samples; Imran et al [36], Islam et al [45], Mohammad et al [26] and Okoye et al [28] observed high nickel concentration ranges of 2.91 -5.52 ppm, 0.0125 -5.1625 ppm, 11.33 -64.33 mg/kg and 2.250 -4.875 mg/kg respectively in their studies, while Suleiman et al [37] observed low nickel level of 0.004 -0.250 µg/ml. Although nickel has been found to serve biological functions in some animals and plants, its essentiality in humans has not been established [46].…”

The concentrations of heavy metals in some commercial poultry feeds available in Abuja, Nigeria was investigated. Poultry feed rations (starter, grower, finisher and layer) of seven different feed brands available in Abuja were purchased from their various distribution outlets. The nitric acid digestion method followed by Flame Atomic Absorption Spectrophotometry technique were used for metal content quantification. Analytical method validation was performed using IAEA-V-8 Rye flour certified reference material and good recoveries were obtained in all the metals indicating the accuracy of the applied analytical procedure. The mean of heavy metal concentrations (μg/g dry weight) in the poultry feeds were 2.31 ± 1.23, 0.43 ± 0.20, 1.66 ± 0.82, 23.35 ± 5.26, 238.09 ± 45.80, 0.61 ± 0.26, 99.57 ± 15.63 and 68.21 ± 11.92 for Pb, Cd, Ni, Cu, Fe, Co, Mn and Zn respectively. Generally, the levels of iron, manganese, zinc and copper in the poultry feeds were higher than FAO/WHO, National Research Council (NRC) and Standard Organisation of Nigeria (SON) maximum recommended limits in feeds. Pearson correlation analysis on the metals in poultry feeds showed a significant (p < 0.01) positive strong correlations between Co/Ni (0.658), Mn/Cu (r = 0.566), Zn/Cu (r = 0.683) and Zn/Mn (r = 0.758) suggesting that these metals could have had the same pathway into the feeds.

“…All the studied feed samples contained Mn at a concentration lower than the recommended value . The concentration detected for all the feed samples was found lower than those obtained by many previous reports (Alkhalafet al, 2010;Rahman et al, 2014;Okoyeet al, 2011b;Korish and Attia, 2020) and higher than the studies investigated (Imran et al, 2014;Suleiman et al, 2015). Among the four different studied samples, layer feeds of Ind-Ajn farm was also identified with the highest amount of Fe content (108.392±0.002 mg/kg) which was slightly higher than the mean maximum value (102.0175 mg/kg) obtained by Islam et al, 2017 and 91.86±8.98 mg/kg reported by Imran et al, 2014, Rahman et al, 2014and Korish et al, 2020 recorded the Fe level in the poultry feed samples in the ranges from 1026.67±8.15-3053.33±18.24 mg/kg and 99.4-142.9 mg/kg, respectively.…”

Considering the potential health hazardous effects, the distribution and deposition of heavy metals and trace elements including Mn, Fe, Cu, Zn, Cd, Cr, and Pb in different tissues (skin, brain, liver, meat, and bone) of broiler and layer chickens, their feeds, litter, and eggs were analyzed using atomic absorption spectrophotometer (AAS) after nitric/perchloric acid digestion. The samples for this study were taken from four poultry industries located at Sreepur upazila of Gazipur district of Bangladesh. The observed levels of heavy metals and trace element contents in different studied samples were to be in the range of 0.143±0.001 to 7.324±0.004 mg/kg for Mn, below the detection limit (BDL) to 324.43±0.003 mg/kg for Fe, 0.451±0.002 to 4.329±0.005 mg/kg for Cu, 0.014±0.001 to 7.413±0.003 mg/kg for Zn, 0.082±0.002 to 7.806±0.002 mg/kg for Cr, 0.112±0.002 to 1.581±0.002 mg/kg for Cd, and BDL to 34.775±0.004 mg/kg for Pb. Although some elements were found at a lower concentration in feed samples, they were found at a higher level in various parts of the examined chickens, eggs, and litter which may be resulted from other sources such as drinking water, soil, and the surrounding environment of the poultry industries. The brain contained a maximum amount of Cd, Cr, and Pb in comparison to other studied tissues of poultry. Most of the chicken body parts showed an excess level of Cr than the recommended guidelines. The Cu and Zn contents were usual in studied egg samples, whereas Mn, Fe, Cd, Cr, and Pb were found higher than their tolerance limits which are highly alarming for public health and demand regular governance and monitoring.

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.
