title: Response of growth-selected Japanese quail lines to tannin levels in grain sorghum diets with suboptimal protein.
abstract: Growth of selected lines of Japanese quail fed grain sorghum diets was evaluated. Suboptimal protein levels (23 and 25%) were used in conjunction with two varieties of sorghum differing in tannin content (.02 vs. 6.06%). Chicks of three related lines of quail differing in growth rates and mature body sizes were fed the diets from 0 to 28 days of age. Growth was significantly reduced (14 and 6%) by substitution of high tannin sorghum for low tannin sorghum in the 23 and 25% protein diets, respectively. No line X diet interaction was observed.
