In Experiment 1, dehulling white lupine (WL) improved growth and feed efficiency of male Large White turkey poults fed 40% WL during 4 to 21 days of age. In Experiment 2, WL was included proportionally with soybean meal in corn-soy diets of female turkeys from 0 to 17 wk of age. Soybean meal: WL ratios (S:WL) were 1:0 (control), 2:1, 1:1, and 6:1. At 17 wk of age hens on S:WL diets of 2:1 had body weights that were similar to those of birds fed the corn-soy control diets. Growth of hens fed S:WL diets of 6:1 was depressed (P less than .05). Growth depressions were greatest earlier in the study; older birds made compensatory gains. Feed efficiency of hens fed S:WL diets of 1:1 was poorer than that of controls during 0 to 11 wk but better than that of controls after 11 wk of age. Feed efficiency values were similar during 0 to 17 wk for hens fed control and S:WL diets of 2:1 and 1:1. Sensory evaluation of roasted light and dark meat of market birds revealed no taste differences in relation to WL level in the diet.
在实验1中，对4至21日龄的雄性大白火鸡雏鸡饲喂40%的去皮白羽扇豆（WL），可提高其生长性能和饲料效率。在实验2中，在0至17周龄的雌性火鸡的玉米 - 大豆日粮中按比例添加WL与豆粕。豆粕与WL的比例（S:WL）分别为1:0（对照）、2:1、1:1和6:1。在17周龄时，饲喂S:WL比例为2:1日粮的母鸡体重与饲喂玉米 - 大豆对照日粮的母鸡相似。饲喂S:WL比例为6:1日粮的母鸡生长受到抑制（P小于0.05）。在研究前期生长抑制最为明显；年龄较大的鸡只出现了补偿性生长。饲喂S:WL比例为1:1日粮的母鸡在0至11周龄期间的饲料效率低于对照组，但在11周龄后高于对照组。在0至17周龄期间，饲喂对照日粮以及S:WL比例为2:1和1:1日粮的母鸡的饲料效率值相似。对上市鸡只的烤浅色肉和深色肉进行感官评价发现，日粮中WL水平对肉的口味没有影响。
