This study evaluated the effect, on productive performance and on egg quality, of replacing corn with broken rice in the feed of 64-148 day-old Japanese quails. The experiment was conducted in a randomized complete block design with five treatments consisting of five inclusion levels of broken rice (0%, 25%, 50%, 75%, and 100%) with eight replicates of eight birds each. No significant differences were observed in productive performance variables across treatments (P > 0.05, all). Regarding egg quality, no significant differences were observed in yolk percentage, specific gravity, or Haugh unit across treatments (P > 0.05 for all parameters). However, yolk color index was negatively affected by dietary rice husk levels (Y = 4.080 - 0.0293X, R² = 98.56%; P < 0.05). Thus, corn can be replaced with up to 100% broken rice in diets for laying Japanese quails without losses in productive performance or egg quality, but corn replacement with broken rice affects yolk color.Downloads
