Results from this study5

No result from this study comes from a test of the peptide.

Studies that did not test the peptide alone5

In this study, Thymulin (serum thymic factor) was a lab tool or a carrier, part of a mix, or the subject of a lab method. These results are not evidence about taking Thymulin (serum thymic factor).

    Summary
    Breeders of the first group, immunopotentiated by thymulin and zinc, were able to induce the earliest antibodies in their pooled sera at 2 weeks post the first SE-vaccination, specific to fimbriae (approximately 21 KDa) of SE.

    Summary · context
    However, the second group that was only vaccinated with the same SE-vaccine produced specific antibodies to fimbriae at 3 weeks following the second vaccination (22 weeks of age).

    Summary
    The presence of the earliest antibody-immunopotentiation to fimbriae of SE in breeders of the first group, administered thymulin and zinc, was associated with the lowest frequency of SE-infected ceca (10%) among the challenged groups.
