Cross Lohmann Brown hens' eggs were investigated in connection with pollution level of lasalocid sodium in feed on trial conditions. The lasalocid sodium content in feed of hens' trial groups was from 1 up to 125 mg/kg, but eggs obtained from these hens contained - from 0.14 to 3.68 mg/kg lasalocid sodium. Increasing lasalocid sodium in feed increased this level in eggs, too. The correlation coefficient r=0.91. According to obtained data of statistic analyses from content of lasalocid sodium in eggs in local conditions, we elaborated and estimated carry over by following formula: y=0.8243 ln(x) - 0.288, where: x - the content of lasalocid sodium in feed, ln - natural logarithm, y - predictable content of lasalocid sodium in eggs.
