Five sows were inoculated with a cell-cultured, cytopathic strain of the virus of transmissible gastroenteritis (TGE). Two sows were inoculated intramuscularly, and three by the intramammary route. The response was measured by the neutralizing antibody titers in the serum and the milk, and by the protection against experimental challenge of piglets nursing the sows. There were no marked differences in the serum or milk antibody titers resulting after the two methods of inoculation, although milk titers at the time of challenge were higher after intramammary inoculation. Piglets nursing sows inoculated by the intramammary route were protected to a greater extent than those nursing sows inoculated intramuscularly.
五头母猪接种了细胞培养的、具有细胞病变效应的传染性胃肠炎（TGE）病毒株。两头母猪通过肌肉注射接种，三头通过乳腺途径接种。通过血清和乳汁中的中和抗体滴度以及对哺乳母猪所产仔猪进行实验性攻毒的保护情况来衡量反应。两种接种方法后血清或乳汁抗体滴度没有显著差异，尽管在攻毒时乳腺接种后的乳汁滴度更高。通过乳腺途径接种的母猪所哺乳的仔猪比肌肉注射接种的母猪所哺乳的仔猪受到了更大程度的保护。
