Effect of Graded Replacement of Corn by Broken Rice in Growing Japanese Quail Diets on Growth Performance, Carcass Traits and Economics
E.A. Ashour, F.M. Reda and M. Alagawany

Abstract:
This study evaluated the effect of replacing maize with broken rice (0, 10, 20, 30, 40 and 50 %) on growth performance, feed utilization and carcass traits of growing Japanese quails (1-5 weeks of age). A total of 324 quails (1 week old) were used in a complete randomized design experiment with six treatment groups. Each group was subdivided into three replicates with 18 birds per replicate. Live Body Weight (LBW) and Body Weight Gain (BWG) were significantly (p<0.05) affected by treatments throughout the experiment. The highest values of LBW (189.53g) and BWG (5.70 g) achieved by birds fed broken rice at 20% level during all the experimental periods compared to the other groups. Feed Intake (FI) was significantly (p<0.05 or 0.01) affected by broken rice replacement during all the experimental periods. Feed Conversion Ratio (FCR) was statistically (p<0.05) influenced by broken rice levels through 1-5 weeks of age only. Replacement of corn by broken rice in the diets did not affect (p>0.05) dressing, carcass, giblets, heart, liver and gizzard percentages of meat-type quails as compared to corn-soya diet. Economical efficiency did not affect with the different levels of broken rice throughout the experiment. Based on the present findings, broken rice can be considered a potential substitute of corn up to 50% in meat-type quail diets. Since, it is a by-product of rice processing its composition may vary, studies for determination of metabolizable energy and digestible amino acid contents may allow maximizing its inclusion in quail diets.
