“…Decreases in FC and BWG were seen from week 3 onwards, with the adverse effects increasing progressively until the end of the trial period. These data agree with the findings of Arafa et al, (1981), Chang and Hamilton (1982), Rao et al, (1990) and Sadana et al (1992) who reported that FC and BWG decreased significantly from the 3rd week of the experiment in Japanese quail fed on diets containing 0·5 to 2·1 mg AF/kg. In this study, the cumulative reductions were 14% in FC and 27% in BWG.…”

Clinoptilolite (CLI, a natural zeolite), incorporated into the diet at 50 g/kg, was evaluated for its ability to reduce the deleterious effects of 2.0 mg total aflatoxin (AF;83.06% AFB1, 12.98% AFB2, 2.84% AFG1 and 1.12% AFG2)/kg diet on growing Japanese quail chicks from 10 to 45 d of age. A total of 40 Japanese quail chicks were divided into 4 treatment groups (control, AF, CLI, AF plus CLI) each consisting of 10 chicks. The performance of the birds was evaluated. The AF treatment significantly decreased food consumption and body weight gain from the 3rd week onwards. The adverse effect of AF on food conversion ratio was also significant from week 4 of the experiment. The addition of CLI to an AF-containing diet significantly reduced the deleterious effects of AF on food consumption, body weight gain and food conversion ratio. Food consumption was reduced by 14% in quail chicks consuming the AF diet without CLI, but by only 6% for quail chicks consuming the AF plus CLI diet. Similarly, overall body weight gain was reduced by 27% in birds consuming the AF diet without CLI, but by only 8% for birds consuming the AF plus CLI diet. The addition of CLI to the AF-free diet significantly decreased food consumption and body weight gain during week 4, but these parameters were similar to the controls in week 5. No mortality was observed in any of the groups. These results suggest that CLI effectively diminished the detrimental effects of AF on the variables investigated in this study.

RESUMO.-[Eimeria spp. de codornas japonesas (Coturnix japonica): novas características e ferramentas de diagnóstico.] A codorna japonesa Coturnix japonica originária do norte da África, Europa e Ásia, é utilizada mundialmente como um animal experimental e modelo para avicultura. O presente trabalho caracteriza Eimeria bateri, Eimeria tsunodai e Eimeria uzura recuperadas de C. japonica. Baseado no fato de que as codornas têm uma distribuição global, como são os seus coccídios, os resultados deste estudo devem propiciar o diagnóstico destas Eimeria spp. em outras regiões e continentes. Eimeria bateri demonstrou a maior intensidade de infecção e eliminaram oocistos a partir do quarto dia após infecção, em contraste E. tsunodai e E. uzura eliminaram oocistos a partir do quinto dia após infecção. As três espécies foram morfometricamente semelhantes e polimórficas. No entanto, a aplicação da regressão linear, histogramas e ANOVA proveram meios para a identificação destas espécies. Finalmente, o algoritmo foi totalmente eficiente uma vez que valores resultantes não foram sobrepostos. TERMOS DE INDEXAÇÃO: Coccidiose, diagnóstico, Eimeria bateri, Eimeria tsunodai, Eimeria uzura. INTRODUCTIONThe breeding of Japanese quails Coturnix japonica has excelled in aviculture, due to increased consumption of exotic meats and eggs, and represents an alternative to chicken production. In the USA, Japanese quails were introduced in the 1950s, and at that time the breeding of Japanese quails was already widespread in European countries. In Brazil, Japanese quails were introduced in the 1950s, but large scale production began in the mid 1960's (Howes 1964, Murakami & Ariki 1998, IUCN 2013, Jatoi et al. 2013.In addition to its importance for aviculture, the Japanese quail has become, in recent decades, an important experimental animal for scientific research. It is used extensively in studies examining genetics, nutrition, toxicology, em- The Japanese quail Coturnix japonica originated from North Africa, Europe and Asia, is used worldwide as an experimental animal and model for aviculture. The current paper characterizes Eimeria bateri, Eimeria tsunodai and Eimeria uzura recovered from C. japonica. Based on the fact that quails have a global distribution, as are their coccidia, the findings of this study should provide the means for diagnosis of those Eimeria spp. in other regions and continents. Eimeria bateri showed the greatest intensity of infection and shed oocysts from the fourth day after infection; in contrast, E. tsunodai and E. uzura shed oocysts from the fifth day after infection. The three species shared a high degree of similarity and were all polymorphic. Yet, the application of line regressions, histograms and ANOVA provided means for the identification of these species. Finally, the algorithm was very efficient since verified that resultant values were not superimposed.

“…The aflatoxin effect associated to the parasitism by eimerid coccidia in Japanese quails never was tested, but a single study exists which report their effects on the interaction in body weight, organs size and in the oocysts reproductive potential (RAO et al, 1990).…”

E-mail: bertobp@ufrrj.brThe purpose of this study was to characterize Eimeria bateri oocysts and to evaluate the aflatoxin effect in the morphometry of sporulated oocysts in Japanese quails infected naturally. Of a total of 50 quails naturally infected by E. bateri were randomly divided into two groups with 25 birds each. In one of them, quails were orally administered with aflatoxin in dose of 0.04 mg/kg body weight previously. Both experimental groups shed E. bateri oocysts. These oocysts were subspherical to ellipsoidal, 25.1 × 18.9 μm, with bi-layered wall. Micropyle and residuum were absent, but one or more polar granules were present. Sporocysts elongate ovoid, 12.5 × 7.4 μm. Stieda and substieda bodies were present. Sporocyst residuum was dispersed and sporozoites presented a nucleus and a refractile body. Histograms confirmed the presence of a single species, E. bateri. Linear regression proved that E. bateri oocysts are polymorphic, due, basically, to shape of these oocysts. The comparative morphometry between two experimental groups demonstrated that the aflatoxin influenced significantly in the E. bateri oocysts.
