Coccidiosis is a serious obstacle to sheep production, which is becoming a limiting factor, especially with regard to lamb production. However, there are few studies on this parasite in the State of Rio Grande do Norte. The aim of this study was to evaluate the action of decoquinate, added to mineral salt, for controlling Eimeria infection in lambs, and to identify which species are infecting sheep in the eastern region of the state. This study was carried out from August 2009 to January 2010, and used 76 animals. These were divided into two treatment groups: one with common mineral salt, and the other with mineral salt enriched with 6% micronized decoquinate. Fecal samples and body weight measurements were taken every 14 days for parasitological diagnosis, weight gain follow-up and quantitative analysis. The study showed that there was a significant difference in OPG only at the 7th collection, but no significant difference in weight gain. The Eimeria species found were E. ahsata. E. crandallis. E. granulosa. E. intrincata. E. ovina. E. faurei. E. ovinoidalis. E. pallida and E. parva. It was concluded that addition of decoquinate to mineral salt gave rise to lower oocyst elimination, thus favoring eimeriosis control in sheep.

ABSTRACT: Eimeria infections are common in the sheep industry worldwide. Lambs are more susceptible to coccidiosis, especially in stressful conditions, being infected by different species of the parasite. Eimeria crandallis and Eimeria ovinoidalis are considered the most pathogenic, causing reduced growth, dehydration, anorexia, and death. In this study, the frequency of Eimeria species was evaluated in lambs from the southern region of the Rio Grande do Sul state, Brazil. Fecal samples from 248 lambs, from 19 farms, were tested for the presence of oocysts. The positive samples were re-examined and the sporulated oocysts analyzed morphometrically to identify the presence of Eimeria species. In 100% of the evaluated farms, there were animals positive for the protozoan. The frequency of Eimeria species was: E. ovinoidalis (94.74%), E. crandallis (89.47%), E. granulosa (78.95%), E. parva (68.42%), E. ahsata (63.13%), E. punctata (42.11%), E. bakuensis (36.84%), E. faurei (10.53%), and E. pallida (5.26%). Mixed infection was found in 94.74% of the samples. This research describes, for the first time, the occurrence of E. crandallis and E. ovinoidalis infecting lambs in the study area. The wide distribution of this protozoan and the high frequency of pathogenic species show the importance and potential damage of sheep coccidiosis in herds from Rio Grande do Sul.

Rabbit breeding is one of the promising branches of animal husbandry, but its development is hampered by various diseases. The problem of the pathogenic influence of parasites of the genus Eimeria on the organism of rabbits at different infective doses is still quite urgent. The study was conducted on hybrids of rabbits of Soviet Chinchilla and Californian breeds at 30 and 45 days of age. Within the framework of the experiment 6 groups of young rabbits were formed by the method of pair-analogs. The one-day old rabbits in the experimental groups were infected with oocysts of the association of Eimeria species E. perforans and E. irresidua at doses of 100 000 (2 groups) and 200 000(2 groups) per head, and in control groups (2 groups) - remained intact throughout the experiment. To analyze the pathogenic effect of parasites determination of meat productivity, veterinary and sanitary assessment of carcasses, linear measurements of intestinal length as well as histological studies of the walls of the small intestine were carried out in rabbits of these age groups. The research results showed that rabbits-hybrids infected at a dose of 100 000 and 200 000 oocysts per head demonstrate significant reduction of the increase in live weight and slaughter yield, despite the preservation of the retail display of the carcasses.
