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.
Coccidiosis is a common disease in racing pigeons. The aim of this study was to assess the efficacy of toltrazuril in coccidiosis control in pigeons before and during the racing season. Bulk feces samples collected from 1140 birds were analyzed by the flotation method according to Fülleborn with the use of Darling’s solution. Eimeria spp. oocysts were counted in five fields of vision, and their diameter was an indicator of invasion intensity. Coccidiosis was controlled with toltrazuril (Baycox) applied twice at three-day intervals, at a dose of 20 mg/kg body weight, with drinking water. The severity of coccidial infection was determined one day prior to treatment, and the efficacy of toltrazuril was assessed 2, 4 and 6 weeks after treatment and 3 days after each race. Eimeria spp. were detected in all feces samples collected from 4 pigeon lofts. Two weeks after the first administration of toltrazuril, only single oocysts were present in feces samples, while no oocysts were found during the next examination. Coccidia appeared again in the excreta of racing pigeons (group 2) after the second and third race, whereas in pigeons that stayed in the loft (group 1) reinvasion was noted after the fourth race of group 2 birds. The results of the study indicate that Baycox administered twice was highly effective in controlling Eimeria spp. invasion over a period of more than ten weeks.
The studies were carried out in the farm SK Bielin, on 45 calves. The prevalence and intensity of the Coccidia infection were determined by means of the Willis-Schlaaf's and McMaster's methods. Whereas the Coccidia composition in the examined animals was determined by the morphological features of the oocysts and the sporulation time. The following six Eimeria species were isolated in the commercial fanns - E. bovis, E. aubernensis, E.zurni, E. ellipsolidalis, E. subspherica and E. cylindrica. The calves were divided into control and two experimental groups - 15 animals per group. Anticoc was administered for 5 days in a dose of 0,9 ml/10 kg of body weight. Baycox was administered twice in 7 days interval in a dose of 20 mg/kg of body weight. The weight gain and the course of coccidia infection in calves before and after treatment with Baycox and Anticoc were examined. In control group the coccidia infection was very high. After administration of Anticoc the intensity of coccidia infection was falling down and 0-180 oocysts were found in 1 g of feces. After administration of Baycox the intensity of coccidia infection was very low and only 0-80 oocysts were found in 1 g of feces. The results were analysed statistically, and significant differences between the treated and untreated animals at P≤0.01 were observed.
The aim of the research was to establish the usefulness of Sacox and Baycox coccidiostatics for control of coccidiosis and their influence on the breeding of lambs. The research was carried out on 600 lambs, naturally infected with coccidia and divided into 3 groups - 200 animals in each, after separation from ewes and selected in terms of sex, type, date of birth and weight. Research on the influence of coccidiostatics on the duration of coccidiosis and on the breeding sheep were conducted. The research group consisted of 600 lambs (3 groups). Two coccidiostatics were used - salinomycin (Sacox, Hoechst) and toltrazuril (Baycox, Bayer). Baycox was used for the first time to control sheep coccidiosis in Poland. Salinomycin was administered as a feed additive in a dose of 40 ppm; however, toltrazuril was applied individually - twice on the 110 and 117 day of life in doses of 20 mg/kg body weight. The extent and intensity of coccidia infection was ascertained by the Willis-Schlaaf and McMaster methods. The weight gain of lambs was determined once a month on the basis of individual weight. The results of the research verify that salinomycin and toltrazuril are highly efficient in protecting against the protozoa of the genus Eimeria and these two drugs could be used for coccidia control in lambs. Special attention was paid to toltrazuril; this preparation is very active against all intracellular stages - schisogony and gamogony and it in turn could be used for treatment of clinical coccidiosis. Both coccidiostatics have a positive influence on the weight gain of lambs.

The study was carried out on material consisting of 110 goats. The total number of 9 species of coccidia were found: E. christenseni, E. arloingi, E. jolchijevi, E. Ninakohlyakimovae, E. alijevi, E. apsheronica, E. caprina, E. caprovina and E. hirci. The nanny - goats were infected in 81 per cent and the kids in 100 per cent. The intensity of Eimeria infection in kids were within the range of 1200 to 202000 of oocysts per 1 g of faeces. In the flock clinical symptoms in abo ut 50 per cent of kids were observed. After Baycox administration in 4 kids single oocyst were found only.
