An experiment was conducted to evaluate the effects of broken rice inclusion as substitute for corn in the diet on the performance, carcass yield, and economic viability of meat-type quails between 7 and 49 days of age. A number of 288 quails was distributed according to a completely randomized design into six treatments with six replicates of eight birds each. Treatments consisted of increasing levels of broken rice (0, 20, 40, 60, 80 and 100%) in replacement of corn. Increasing levels of corn substitution by broken rice in the diet of 7- to 49-day-old meat-type quails did not affect feed intake, weight gain or feed conversion ratio (p>0.05). Relative to carcass traits, the inclusion of broken rice in the diets did not influence (p>0.05) dressing percentage or breast, leg (thigh+drumstick), liver, and gizzard yields. Moreover, feed cost per kilogram of live weight gain, cost index, and economic efficiency index were not influenced by the replacement of corn by broken rice in the diets. The performance, carcass traits and economic viability of broilers fed the different levels of broken rice inclusion were not different from the control group (p>0.05). These results indicate the economic viability of total replacement of corn by broken rice in the feeding of meat-type quails.
