ABSTRACT: The objective of this study was to evaluate the effect of replacing corn with sorghum in feed on performance, carcass yield, and composition of specialized meat cuts in quails. A total of 1200, 1-day-old female quails were raised up to 42 days of age. The completely randomized design consisted of four treatments with six replicates each and with 50 quails in each cage. Treatments consisted of four levels of sorghum replacement in the diet (0, 40, 60, and 100% sorghum). All birds were weighed to assess the weight gain. Feed conversion was calculated as the relationship between feed intake and weight gain. Mortality was reported daily and calculated at the end of each week. At 42 days, the birds were slaughtered and the carcass, thigh and drumstick, and breast yields were assessed. Mineral matter, ether extract, and crude protein analyses were performed using breast cuts and thigh + drumstick cuts. No significant differences were noted in cut performance, yield, or composition. Thus, it can be concluded that the ground grain sorghum can entirely replace corn in quail feed, as it does not negatively affect carcass performance, yield, and nutritional quality.
