dc.description.abstractTwenty-four male albino rats, Wistar`s strain of 21-22 days old, with average weight of 27.6-27.9 g were fed sun dried coconut oil meal (SDCOM), oven dried coconut oil meal (ODCOM), sun dried fermented coconut oil meal (SDFCOM) and oven dried fermented coconut oil meal (ODFCOM) to evaluate the protein quality indices using a nitrogen free diet and casein nitrogen based diet as reference. The feed intake (FI), protein intake (PI) and faecal nitrogen were all significantly (p<0.05) higher in the reference diet and SDFCOM. The body weight gain in the reference diet was significantly (p<0.05) higher than the others but followed by values recorded by rats on SDFCOM and ODFCOM. Urinary nitrogen was highest in (p<0.05) in SDCOM. The nitrogen retained was higher (p<0.05) for rats fed SDFCOM and ODFCOM. Apparent Digestibilities of Nitrogen (AND) were similar for the reference diet, SDFCOM and ODFCOM. The True Protein Digestibility (TPD), Biological Value (BV), Protein Efficiency Ratio (PER), Net Protein Utilization (NPU) and Net Protein Ratio (NPR) were all highest in the reference diet and followed by ODFCOM and lowest in SDCOM while the gross protein value (GPV) was highest (p<0.05) for rats on ODFCOM. The TPD and GPV were strongly correlated (Y = 5.716x-267.07) with R 2 = 0.98. Amino acids values for the four samples were similar but leucine was highest in ODCOM. The determined values of mineral composition for SDCOM, ODCOM, SDFCOM and ODFCOM were also very similar, but phosphorous had the highest coefficient of variation (24.26%) followed by Ca, K, Zn, Mn, Mg and Cu. Oven dried fermented sample of coconut oil meal (ODFCOM) exhibited better protein quality index values than the others sun dried.en_US
