| 摘要 |
The present invention is a novel approach for stimulating or enhancing immune T-cells in an animal. In particular, the invention is directed to an egg, and more specifically, a fraction thereof of a size less than 3000 daltons, obtained from an avian that has been hyperimmunized with one or more immunogens. The ingestion by an animal of an effective amount of the hyperimmune egg or fraction thereof causes a significant increase in the overall T-cell population in that animal.
