Application of different chemical and biochemical treatments to improve nutritive potential of defatted rice polishing

This Study was conducted to improve the nutritional value of defatted rice polishing for broiler rations by applying different chemical treatments under complete randomized design. For this purpose, day old broiler chicks (n=225) were randomly divided into five groups i.e. A, B, C, D and E. Each group was further divided in three subgroups R1, R2, R3 with 10%, 20% and 30% defatted rice polishing containing ration, each subgroup having 15 chicks. Groups A, B, C, D and E were fed ration containing defatted rice polishing as raw, hydrochloric acid (HCl) treated, Sodium hydroxide (NaOH) treated, hydrogen peroxide (H2O2) treated and Kemzyme (enzyme) added. Results showed that at 10 % inclusion (R1) of defatted rice polishing (DFRP) maximum (P>0.05) feed intake was observed in group A while minimum in groups C and B. weight gain was highly significant (P>0.05) in group D than groups C and B. In FCR, group D showed better performance while least in group A. At 20% DFRP inclusion (R2), no difference was found in feed intake between groups A, B, C and D. In weight gain, highest value obtained in groups D, B and C while lowest (P>0.05) in groups A and E. In FCR, group D was better and was statistically similar to groups B, C and E, however, group A showed significantly poor (P>0.05) FCR than all treated DFRP groups. At 30% DFRP inclusion (R3), difference in feed intake was non significant among all groups. Maximum (P>0.05) weight gain observed in group A while lowest in D. However, better FCR observed in groups A, B and C which was significantly different from groups D and E. It was concluded that up to 20% H2O2 treated DFRP can be effectively used in broilers diets.
