Western blot detection of the phyA2 protein in corn, diet, digesta, blood, tissues, and eggs of laying hens fed diets containing control corn (CC) and phytase transgenic corn (PTC) for 16 weeks1.

1Number of samples that tested positive for the phyA2 protein out of 8 samples analyzed. One sample was tested per laying hen (n = 8 laying hens per treatment).2Percentage of samples positive for the phyA2 protein taken from PTC fed laying hens i.e. (number of positive samples/number of samples tested)×100.1. 所分析的8份样本中，phyA2蛋白（phyA2 protein）检测呈阳性的样本数量。每只产蛋鸡仅接受1份样本检测，每组处理对应8只产蛋鸡（n=8）。2. 取自饲喂PTC日粮的产蛋鸡的phyA2蛋白阳性样本占比，计算公式为（阳性样本数/检测总样本数）×100。
