Potential Feeding Value of Deoiled Rice Bran by Japanese Quails. 2. Effect on Nutrient Utilization
S. K. Bhanja, S. V. S. Verma
Abstract
The implications of incorporating deoiled rice bran (DORB) in diet on the utilization of certain nutrients had been examined through balance studies made with 6- and 10- week-old Japanese quails. The stuffs evaluated in this study had their origin from two different types of processes- a batch extraction (DORB-B) and another continuous process (DORB-C), and each included at 10, 20 or 30% level in an iso-nitrogenous and iso-caloric diet. On chemical analyses, the DORB-B was found to contain crude protein, 19.0; ether extract, 0.79; total ash, 17.05; Ca, 0.11; P, 1.92; glucose, 2.35 and starch 11.22 g/100 g day matter. Corresponding values for DORB-C were 15.02, 1.56, 13.0, 0.40, 2.76, 2.16 and 19.0, respectively. The data on nutrient balances with quails fed diets containing the two-types of DORB suggested no significant (p>0.05) differences in per cent retention of diet dry matter (DM), organic matter (OM), ether extract (EE), gross energy (GE), nitrogen (N), crude fiber (CF), calcium (Ca) or phosphorus (P) content attributable to the extraction process. The age of the birds also appeared to have no significant (p>0.05) effect on nutrient utilization by them. However, the level of inclusion of DORB had a significant (p<0.05) effect on nutrient utilization by quails in that the retention of dietary N, EE, CF, Ca and P was better at lower than at higher levels. It is concluded that the DORB, irrespective of extraction process, can safely be employed upto 20% level in diet of adult Japanese quails without noticeable interference in utilizing the major dietary nutrients
