Tylosin tartrate (25 mg/L) significantly inhibits methane production relative to unamended controls, thus indicating that Tylosin tartrate at concentrations commonly found in swine lagoons can negatively impact anaerobic metabolism. Tylosin disappearance follows a biphasic pattern, where rapid initial loss is followed by a slow removal phase. The 90% disappearance times for tylosin, relomycin (tylosin D), and desmycosin (tylosin B) in anaerobically incubated slurries are 30 to 130 hours, and aerating the slurries reduced the 90% disappearance times to between 12 and 26 hours. Tylosin tartrate is stable for at least one month when stored in Milli-Q water at pH 5.7 to 6.7 at 22 ℃.

Tylosin increases splenocyte proliferation and splenocyte conditioned medium (CM) proliferative activity above control levels from whole splenocyte cultures in chickens. Tylosin also increases antitumor activity of splenocytes in chickens. Tylosin tartrate (50 mg/kg) administered orally twice daily for 10 days, beginning 14 days after intranasal infection, significantly reduces the incidence and severity of macroscopical pneumonic lung lesions in neonatal piglets. After tylosin tartrate administered intravenously (i.v.) at 10 mg/kg in camels, serum tylosin concentrations in the water-deprived camels are significantly higher, rate of drug elimination is slower, the volume of distribution is significantly smaller, and total body clearance is significantly slower than in the normal camels. On the other hand, serum tylosin concentrations are lower in the water deprived camels and the mean absorption time is significantly shorter in camels treat with tylosin tartrate (20 mg/kg i.m.).
