  Biochemical, physical and performance evaluation studies were carried out in order to determine the quality of four commercial growers rations, (GF, SF, TF and VF) and five commercial layer rations (GF, SF, TF, VF and LF) manufactured in Nigeria. Percentage moisture content (% MC), Ash content (% AC), Ether extract (% NFE) and calculated metabolizable energy (ME) in MJ kg-1 were determined by proximate analysis and compared with the nutrient values declared on the brand labels. Performance was investigated using 60, 4-month-of-lay commercial laying birds in a 10-week experiment. Four treatment diets including three commercial rations (GF, SF and LF) and a control diet (CF) were fed to 3 replicated groups of the experimental birds each in a completely randomized design (CRD) experiment. Percentage MC of TF growers ration (14.75%) and GF layers ration (17.25%) were significantly (p<0.05) higher than others. Both the analyzed and declared values of crude protein in both feed types were statistically similar (p<0.05) for all feed brands. All other parameters showed either a significantly higher or lower values when comparing the analyzed values with the declared values of the nutrients in all feed brands. TF and GF recorded significantly higher ME (MJ kg-1) in growers and layers rations respectively than the rest. The overall mean weights of feedbags ranged from 24.66±0.52 kg for GF to 25±0.02 for VF and were statistically similar to the declared 25 kg/bag of feed by manufacturers. Average feed intake was significantly (p>0.05) lower in the control diet (CF). Highest body weight change was recorded in LF and CF while GF and SF were similar. CF, SF and LF, though statistically similar (p>0.05) recorded higher percentages of her-day production than GF. LF, CF and GF on the other hand, recorded significantly higher average egg weight than SF (p<0.05). SF was the most economical in terms of cost of feed kg-1 egg and per kg feed. Commercial feed millers seem to more concerned with the CP% content of their feeds while compromising the quality of other nutrient components.
