In three trials with a total of 3240 white laying hybrids, 10 to 72% Triticale of the variety "Grado" was used as a substitute for maize and wheat. The feeding of Triticale had no influence on feed consumption, laying performance, feed efficiency, mortality or weight gain. In two of three trials the egg weight was lowered with an increasing amount of Triticale in the diet. After supplementation of 1 or 1.5% sunflower oil to the diets with 50 resp. 72% Triticale the egg weight increased again to the level of the control group. With the exception of one group, there was no correlation between breaking strength and deformation of the eggs. The colour intensity of the egg yolk was decreased with increasing amounts of Triticale in the diet. It can be concluded, that laying hen feed supplemented with oil may contain up to 50% Triticale, but in non-supplemented diets the highest amount of Triticale should be only 20% because of the risk of linoleic acid shortage.
在三项总计涉及3240只白来航杂交蛋鸡的试验中，使用了10%至72%的“格拉多”品种小黑麦替代玉米和小麦。饲喂小黑麦对采食量、产蛋性能、饲料效率、死亡率或体重增加均无影响。在三项试验中的两项中，随着日粮中小黑麦含量的增加，蛋重降低。在分别含有50%和72%小黑麦的日粮中添加1%或1.5%的向日葵油后，蛋重又回升至对照组水平。除一组外，蛋的抗压强度与变形之间没有相关性。随着日粮中小黑麦含量的增加，蛋黄颜色变浅。可以得出结论，添加了油的蛋鸡饲料中可含有高达50%的小黑麦，但在未添加油的日粮中，由于存在亚油酸短缺的风险，小黑麦的最高含量应仅为20%。
