The studies were carried out on 35 000 broiler chickens kept in two broiler-houses of Bios type and 11 000 replacement chicks (in two hen houses, 5 500 in each one). Two coccidiostatics were administered, i. e. Cygro (5 ppm) and Diclazuril (1 ppm) as feed additives in broiler chickens. Replacement chickens were being given the coccidiostatics for 16 weeks of their life. In one poultryhouse Diclazuril and in another one Lerbek were used. The efficacy of the coccidiostatics was assessed on the basis of the following factors: an average body weight (broilers — 4 and 8 weeks, replacement chickens — 8 and 16 weeks), feed consumption, mortality, anatomo-pathological examination after Johnson and Reid and parasitological examination. No differences between the broiler chickens treated with Diclazuril and chickens treated with Cygro were found. In the replacement chickens better findings were observed in the group treated with Diclazuril (lower feed consumption, mortality and oocysts output) in comparison to the Lerbek group of chicks. The results of the studies showed that Diclazuril had not side effects, prevented poultry from coccidiosis and did not suppress the development of natural immunity of poultry against the disease.

The studies were carried out in two farms - ZZK Kołbacz and SK Bielin, on 60 calves, 30 animals in each farm. The calves ware divided for control and experimental groups - 15 animals per group. Baycox was administered two times in 7 days interval in a dosis of 20 mglkg of body weight. The weight gain and the course of coccidia infection in calves before and after traetment with Baycox ware examined. In control animals during the time of studies the coccidia infection was very hight. After administration of Baycox the intensity of coccidia infection was very low and oocysts were found in same animals, only. In SK Bielin before Baycox was used clinical coccidiosis and mortality of 6.9% calves was observed. After Baycox administration 1.9 % animals died, only. The results ware analyst statistically.

Kokcydioza krolikow i jej zapobieganie

The investigations were performed on 6 farm rabbitries in Wrocław district. Average extensity of coccidia infection was 95%, while intensity ranged from 50 to 408 700 ocysts/g of faeces. Nine species of coccidia were identified. Eimeria perforans (84.5%) and E. Stiedai (73.2%) dominated, E. coecicola was noticed most seldom (20.7%). In young rabbits up to 3 months of life the infections were caused by 5-9 species of coccidia. However, in animals from breeding herd there prevailed infections caused by 1-3 species. Congeneric infections were stated very rarely, i.e. in 5.7% of infected animals only. Dynamic changes in the intensity of coccidia infections in rabbits in the course of one year breeding cycle on one of the farms demonstrated the occurrence of two peaks in females used for reproduction: the first one in the perinatal period and the second one in the period prceding weaning. The letter one, higher than the first one, was caused by keeping young rabbits with mothers for 8 -10 weeks. The studies on the effectiveness of anticoccidial drugs were carried out on California White rabbits (age 5-7 weeks), infected naturally with 9 species of coccidia. Rabbits were given for 5 weeks the following anticoccidials: lasalocid (Avatec), maduramycin (Cygro), robenidine (Cycostat), salinomycin (Sacox), monensin (Elancoban), clopidol + methylbenzoquate (Lerbek) and narasin (Monteban). The best results were obtained with salinomycin at the dosages of 35, 50, 25 ppm and maduramycin at 2 and 3 ppm. Equally effective, but characterized by lower production indices, were: clopidol + methylbenzoquate (216.7 ppm), lasalocid (90, 125 ppm) and monensin (20 ppm). Robenidine was very effective against intestinal coccidia at the dose of 66 ppm, however it had weak effect on E. stiedai 's infection. Narasin and maduramycin (4.5 ppm) had toxic effect on animals. A field trial (anticoccidials applied for 6 weeks in does and their progeny) confirmed high effectiveness of salinomycin (25 ppm), maduramycin (1.5 ppm) and monensin (20 ppm).
