This study examined the effects of dietary quinoa seed (Chenopodium quinoa Willd.) supplementation on production performance, egg quality and internal organ traits in Japanese quails (Coturnix coturnix japonica). A total of 90 six-week-old quails were randomly divided into three groups: a control group and two treatment groups receiving diets supplemented with 5% and 10% quinoa seeds, respectively. Over a 8-week trial, key performance indicators were evaluated, including egg weight, feed conversion ratio, internal organ development, and egg quality traits. Results indicated that 5% quinoa inclusion significantly improved egg weight, feed conversion ratio, and small intestine development (P<0.05). Additionally, both quinoa-supplemented groups showed enhanced yolk pigmentation, with increased yellowness (b) and lightness (L), but a decrease in yolk index. No adverse effects were observed on overall egg production, feed intake, or internal organ weights (P>0.05). These findings suggest that quinoa, particularly at 5% inclusion, is a valuable feed additive for enhancing quail productivity and egg quality without compromising health or performance, supporting its use as a functional and sustainable alternative ingredient in poultry nutrition.
