Two experiments were conducted to evaluate the effects of inclusion of Danish grown quinoa seed (Chenopodium quinoa Willd.) in feed for broilers containing wheat, rapeseed, peas and soybean meal. The effect of dehulling to remove saponins from quinoa was assessed. In the first experiment the broilers received mash feed diets from 6 to 36 days of age. Diets containing 100, 200 and 400 g kg ’ whole quinoa seed, unprocessed and dehulled, were compared with a control feed. A linear growth depression (P I 0.01) with increasing inclusion of quinoa was found. As the chickens grew older the growth depression decreased from 1.8 to 0.8% per 10 g kg-’ quinoa added. A negligible beneficial effect of dehulling (P IO.051 was found only for the first week of the experiment. In the second experiment the broilers received pelleted diets from 0 to 39 days of age. Diets containing 150 g kg-’ unprocessed, 150 g kg- ’ dehulled quinoa and 50 g kg- ’ quinoa germ were compared with the control diet. No effect of dehulling was found. A level of 150 g kg ’quinoa reduced liveweight at 20 and 39 days from 627 to 601 g and from 1760 to 1709 g, respectively, and the feed conversion was increased at 20 days of age from 1437 to 1486 g feed kg- ’ liveweight (P I 0.05). The performance of broilers receiving 50 g kg- ’ of a germ fraction from the dehulling was quite as good as the control. It was concluded that quinoa has potential as broiler feed, but the inclusion should not exceed 150 g kg- ’ of the diet.
