Effects of zeranol implants on post‐castration response in calves

Australian Veterinary Journal, 1990
SUMMARY Suckling and yearling calves were surgically castrated and one half of each group implanted with 36 mg zeranol at time of castration. Both treated and control cattle of each class were maintained as a group and evaluated for swelling of the scrotum, inflammation and healing, plasma prostaglandin levels and weight gain.Swelling and inflammation ...

Effect of Sequential Implanting with Zeranol on Steer Lifetime Performance

Journal of Animal Science, 1988
Three trials involving 513 exotic crossbred steers were conducted to determine the effect of zeranol implanting in the suckling and growing phases on subsequent feedlot performance and carcass characteristics. Treatments were 1) unimplanted control, 0000; 2) implanted twice in the finishing phase, 00II; 3) implanted in the growing phase and twice in ...

A Concise Total Synthesis of (S)-Zearalenone and Zeranol

Synthesis, 2011
A convergent total synthesis of the naturally occurring, 14-membered macrolides (S)-zearalenone and zeranol has been achieved through application of the Diels―Alder reaction, Jacobsen kinetic resolution, Mitsunobu coupling, ring-closing metathesis, and hydrogenation as key steps.

In vitro metabolism of the anabolic drug zeranol.

Journal of environmental pathology and toxicology, 1979
The anabolic drug zeranol, which is employed for livestock breeding was studied for its metabolic fate in vitro using isolated microsomal preparations from bovine liver, uterus, and muscle. Diethylstilbestrol and 17 beta-estradiol were investigated simultaneously for comparison.

Detection of zeranol in the blood of ram lambs by a radioimmunoassay technique

Veterinary Record, 1988
Plasma separated from jugular blood samples from six weaned ram lambs was examined for zeranol after the lambs had been implanted, behind the left ear, with a 12 mg pellet. The results showed that the ipsilateral vein contained significantly more zeranol for up to 100 days after implantation; by 145 to 175 days the difference between the ipsi- and ...

[Determination of zeranol in meat (author's transl)].

Zeitschrift fur Lebensmittel-Untersuchung und -Forschung, 1976
A qualitative and quantitative method for the determination of zeranol in meat and liver is described. The analysis procedure includes methanol extraction, enzymatic hydrolysis of possibly existing conjugates, and liquid-liquid partition, followed by two-dimensional thin layer chromatography.
