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.
