Effect of hydrogen peroxide treatment of defatted rice polishing and its use in broiler diets

Defatted rice polishing is one of the ingredients may serve the desired purpose. Defatted rice polishing/bran are an important by- product of rice milling industry. It is, derived from the outer layer of rice caryopsis during milling and has comparable nutritional profile as compared to other cereal grains. Its potential as feed ingredient can not be absolutely exploited due to the presence of certain antinutritional factors. Such as trypsin inhibitor, crude fiber and haemagglutination, etc. However, various treatments implementation could be resulted ill the elimination of antinutritional factors and yielding it into a useful feed ingredient for poultry. Present study was conducted to observe the impact of defatted rice polishing on the performance of broiler chicks after subjecting it to H2O2 treatment. Six starter and six finisher rations were prepared and designated as A, B, C, D, E and. F. All rations were is caloric and is nitrogenous. Starter and finisher ration A contained 15% H2O2 treated defatted rice polishing. Rations B and C contained 20 and 25% H2O2 treated defatted rice polishing while rations D, E and F contained 15, 20 and 25% defatted rice polishing respectively. Two hundred and forty day old broiler chicks were randomly divided into twenty four experimental units of 10 chicks each under six groups A, B, C, D, E and F. Starter rations were fed up to 28th day of age while the finisher rations from 29th to 42nd day of age. Results of the present study indicates that there was no significant difference in weight gain, feed consumption, feed efficiency and dressing percentage of birds fed different experimental rations. It was concluded from the present study that defatted rice polishing can safely be used up to 25% level without subjecting it to treatment. Inclusion of defatted rice polishing up to 25% level had no adverse effect on the performance of broiler chicks. However, by using defatted rice polishing up to 25 % level ration becomes expensive due to addition of oil.
