Levels of biotin and avidin were assayed in eggs from Small White turkey hens having 12-15 week average hatchability of fertile egg records (HF) of 13 and 99%. The median level and concentration of avidin was higher in eggs of the 13% HF (2.72 mg and 42.5 micrograms/ml, respectively) as compared with the 99% HF (1.39 mg and 23.8 micrograms/ml, respectively). Calculations for total biotin to avidin binding in the eggs revealed that all eggs in the 13% HF and residual free avidin levels after total biotin was complexed to avidin. This complex formation is expected to have limited the availability of biotin for embryonic development.
对平均受精蛋孵化率记录为13%和99%的小型白火鸡母鸡所产鸡蛋中的生物素和抗生物素蛋白水平进行了测定。与孵化率为99%的鸡蛋（分别为1.39毫克和23.8微克/毫升）相比，孵化率为13%的鸡蛋中抗生物素蛋白的中位数水平和浓度更高（分别为2.72毫克和42.5微克/毫升）。对鸡蛋中生物素与抗生物素蛋白的总结合量进行计算后发现，孵化率为13%的所有鸡蛋以及生物素与抗生物素蛋白络合后剩余的游离抗生物素蛋白水平。预计这种络合物的形成会限制生物素对胚胎发育的可用性。
