Spiramycin, oxytetracycline and sulphamonomethoxine contents of eggs and egg-forming tissues of laying hens.


PMID 10638297

Abstract

Spiramycin (SP), oxytetracycline (OTC) or sulphamonomethoxine (SMM) was fed to laying hens at a dietary level of 400 p.p.m. for 7 successive days. After 7 days of medicated feed, the concentrations of SP, OTC and SMM were determined in the blood, liver, ovary, oviducts (magnum and isthmus plus shell gland) and eggs (albumen and yolk) by high-performance liquid chromatography. Of the three drugs, OTC showed the lowest content in the above tissues and eggs, while the reverse was true for SMM. Low concentrations of SP were measured in the blood, whereas contents in the liver and the oviducts were relatively much higher.
