“…In this study, AFB 1 ingestion was 4.7, 9.5 and 18.3 mg/bird/week, respectively, for treatments of 25, 50 and 100 mg kg À1 , as estimated considering the actual concentration of AFB 1 in rations and the total feed consumed in each replicate per week. Although Bintvihok et al (1993) decreased quail egg production after 12-week exposure to 50 mg AFB 1 kg À1 , it appears that egg production is only adversely affected when Japanese quail are exposed to much higher concentrations of AFB 1 (Sawhney et al 1973). However, average egg weight decreased ( p<0.05) only for the group exposed to 100 mg AFB 1 kg À1 , which is in agreement with the results of Sawhney et al for aflatoxin levels above 2 mg kg À1 .…”

The aim was to evaluate the excretion of residues of aflatoxin B(1) (AFB(1)), aflatoxin M(1) (AFM(1)), aflatoxin B(2a) (AFB(2a)) and aflatoxicol (AFL) in eggs of laying Japanese quail fed rations with low levels of aflatoxin B(1) for 90 days. The quail were randomly assigned into four experimental groups and given prepared rations containing either 0 (controls), 25, 50 or 100 microg AFB(1) kg(-1) feed. Thirty-two eggs per treatment were collected on days 1-7, 10, 20, 30, 60 and 90 of the aflatoxin treatment period, and submitted to aflatoxin analysis by high-performance liquid chromatography. Average egg production and feed consumption were not affected ( p > 0.05) by AFB(1). Egg weight was significantly lower ( p<0.05) only for groups exposed to 100 microg AFB(1) kg(-1). Residues of aflatoxins were detected in eggs at levels that ranged from 0.01 to 0.08 microg kg(-1) (AFB(1)), 0.03-0.37 microg kg(-1) (AFM(1)), 0.01-1.03 microg kg(-1)(AFB(2a)) and 0.01-0.03 microg kg(-1) (AFL). Results indicate that the excretion of aflatoxin residues in quail eggs might occur at relatively low concentrations under conditions of long-term exposure of quail to low levels of AFB(1).

“…Studies performed on AF-resistant Japanese quail lines showed that plasma protein and lipid concentrations and liver protein and lipid contents of birds were higher than those in AF-sensitive lines (Pegram et al, 1986). In a previous experiment, laying Japanese quail receiving 2 and 4 mg/kg dietary AF had decreased food conversion ratio (Sawhney et al, 1973). A significant decrease in body weight gain was found in Japanese quail fed on 2·5 mg/kg AF-contaminated diet for 3 weeks (Ruff et al 1992).…”

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.

During aflatoxicosis in Japanese quail, egg production, egg weight, and hatchability were depressed (Sawhney et al, 1973).…”

Aflatoxicosis was induced in young Japanese quail. In the first experiment five replicates of 30 birds per treatment were fed a soy-corn basal ration containing 0, 5, or 10 microgram aflatoxin per gram of feed from 1 to 3 weeks of age. At 3 weeks, the animals were sacrificed and mesurements taken. In the second experiment, 0 to 10 microgram aflatoxin per gram of diet were fed from either 1 to 3 weeks of age or 2 to 4 weeks of age. At 3 weeks of age body weights were significantly (P < .05) reduced and relative liver weights were significantly (P < .05) increased. Testicular weights relative to body weight were depressed by up to 50%. Ovary wet weights, but not relative weights, were reduced. Testicular development (weight) was impaired through 6 weeks of age. Ovarian development, determined both by weight and number of developing follicles, was delayed as long as 3 weeks following withdrawal of aflatoxin from the diet. Radioimmunoassay for circulating androgens revealed that aflatoxin suppressed both the onset of production and the final concentratin of male hormone. The data demonstrate that aflatoxin can exert a deleterious inhibition of sexual development in quail with subsequent impairment of reproductive capacity. These findings raise the implication of potential reproductive failure in economically important species such as broiler breeders.
