Two experiments were conducted to determine the effect of the composition of the grower diet and fat in the layer diet on Broad Breasted Large White turkey hens. In Experiment 1, the turkey hens were fed corn-soybean meal diets containing zero and 3% added fat from 12 to 32 weeks of age. In Experiment 2, they were fed a corn-soybean meal basal and a high fiber diet containing 26% wheat bran. In Experiment 1, during the laying phase, hens were fed a corn-soybean meal basal. This diet was also fed in Experiment 2; however, one-half of the hens on each diet were fed a breeder diet with 8% added fat. The addition of fat to the grower diet in Experiment 1 increased hatchability of fertile eggs. The feeding of the high fiber diet in Experiment 2 decreased body weight at 29 weeks. Feed intake and body weight were increased in the laying house when hens were grown on the high fiber diet. However, other production parameters were not affected by grower diet. The addition of fat to the layer diet resulted in increased egg production, fertility, and body weight. Other production parameters were not affected.
进行了两项试验，以确定育成期日粮组成和产蛋期日粮中的脂肪对宽胸大白火鸡母鸡的影响。在试验1中，火鸡母鸡在12至32周龄期间被饲喂添加0%和3%脂肪的玉米-豆粕日粮。在试验2中，它们被饲喂玉米-豆粕基础日粮和含有26%麦麸的高纤维日粮。在试验1中，产蛋期母鸡被饲喂玉米-豆粕基础日粮。试验2也饲喂这种日粮；然而，每种日粮中有一半的母鸡被饲喂添加8%脂肪的种鸡日粮。试验1中在育成期日粮中添加脂肪提高了受精蛋的孵化率。试验2中饲喂高纤维日粮使29周龄时的体重下降。当母鸡在高纤维日粮中生长时，产蛋舍中的采食量和体重增加。然而，其他生产性能指标不受育成期日粮的影响。在产蛋期日粮中添加脂肪导致产蛋量、受精率和体重增加。其他生产性能指标未受影响。
