Two 28-day experiments were conducted to determine the effects of various levels of ground Sesbania macrocarpa Muhl. seed on mature bobwhite quail. In Experiment 1, S. macrocarpa Muhl. seed levels of 0, 1, 2, 3, 4, and 5% were added to a basal diet at the expense of filler and fed to five replicate groups of six 58-wk-old paired quail (one male and one female). Average daily feed consumption, hen-day egg production, average BW change, mortality, fertility, and hatchability were monitored. Four groups of eight individually caged females, 63 wk of age, were each given a diet containing 0, 2, 4, 6, 8 or 10% ground S. macrocarpa Muhl. seed in Experiment 2. A seventh treatment was added that consisted of 10% ground S. macrocarpa Muhl. from an older seed shipment used previously in work with White Leghorn hens. Increasing S. macrocarpa Muhl. seed levels in Experiment 1 did not cause significant deviations from the control treatment for average daily feed consumption, BW change, hen-day egg production, fertility, total hatchability, or hatchability of fertile eggs. In Experiment 2 neither average daily feed consumption nor hen-day egg production were affected by seed level or source. Quail given the 10% seed level using the older seed shipment had a significantly greater weight loss than the control birds. With the exception of this greater weight loss and in contrast with work involving chickens, dietary levels of ground S. macrocarpa Muhl. seed of up to 10% were acceptable to bobwhite quail.
进行了两项为期28天的试验，以确定不同水平的大果田菁种子对成年北美鹑的影响。在试验1中，将0%、1%、2%、3%、4%和5%的大果田菁种子添加到基础日粮中，取代填充料，饲喂五组重复的、每组六只58周龄的配对鹌鹑（一雄一雌）。监测平均日采食量、母鸡日产蛋量、平均体重变化、死亡率、受精率和孵化率。在试验2中，四组每组八只单独笼养的63周龄雌性鹌鹑分别饲喂含有0%、2%、4%、6%、8%或10%大果田菁种子的日粮。添加了第七种处理，即使用先前用于白来航母鸡试验的一批较陈旧种子的10%大果田菁种子。在试验1中，增加大果田菁种子水平，在平均日采食量、体重变化、母鸡日产蛋量、受精率、总孵化率或受精卵孵化率方面，与对照处理相比均未引起显著差异。在试验2中，平均日采食量和母鸡日产蛋量均不受种子水平或来源的影响。使用较陈旧种子批次饲喂10%种子水平的鹌鹑体重损失显著高于对照鸟。除了这种更大的体重损失外，与涉及鸡的试验相反，高达10%的大果田菁种子日粮水平对北美鹑是可以接受的。
