[The usefulnes of baycox (bayer) for coccidiosis control of lambs].

The aim the studies was to establish the usefulness of Baycox for control of coccidiosis and ITS influence on production results (efficiency) in lambs. The studies were carried out on 200 lambs, naturally infected with coccidia, divided in 2 groups -control and experimental, 100 animals in each, after separation from ewes selected in respect of sex, type, date of birth and weight. Toltrazuiril (Baycox) was used the first time for control of sheep coccidiosis in Poland. Toltrazuril was applied individual, twice at 110 and 117 day of life in a doses of 20 mg/kg body weight. The extensity and intensity of coccidia infection was ascertained by the Willis-Schlaaf and McMaster methods. The weight gain of lambs was stated once a month on the basis of individual weight. It was established that toltrazuril show a high efficiency against the protozoa of the genus Eimeria and drug could be used for coccidia control in lambs. This preparation is very active against all intracellular stages - schisogony and gamogony and it could be used for treatment of clinical coccidiosis. It was established profitable influence on the weight gain of lambs.
