Abstract

    The present study was conducted to investigate the chemical composition of rice polishing available in Pakistan used in poultry rations as an energy source. Chemical analysis of 195 samples was done. Overall, 60% samples had either lower or higher percentage of ether extract as compared to reference value (13-16%). Large number of samples (41.54%) showed lower value of ether extract (less than 13%) that indicate oxidative rancidity of fat.  Inverse correlation of ether extract was found with crude fiber, calcium and phosphorus. Samples were also adulterated with rice husk, as indicated by presence of sand/silica in the samples.

Key words:  Rice polishing, chemical composition, poultry feed.
