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.

“…Wyatt et al (1973) found adverse effects on body weight, liver, pancreas, serum protein, and lipid but not serum cholesterol in broiler breeder males fed 20 ppm aflatoxin for 4 weeks. Briggs et al (1974) studied semen from breeder males during aflatoxicosis. They observed no effect on sperm count, semen volume, or DNA or RNA of semen.…”

“…Aflatoxicosis in white leghorn males resulted in decreased feed consumption, body weight, testes weight and semen volume (Sharlin et al, 1980), and decreased plasma testosterone values (Sharlin et al, 1980). While in broiler breeder males reduction in body weight and mild anemia with no alterations in semen characteristics were observed (Wyatt, 1991;Briggs et al, 1974). In mature laying hens experiencing aflatoxicosis, enlarged and fatty liver and marked decrease in egg production were observed (Hamilton and Garlich, 1972).…”

“…Recently, the influence of aflatoxicosis on reproductive performance of poultry breeding stock has become a question of economic concern. Briggs et al (4) observed no alterations in semen characteristics of mature broiler breeder males experiencing aflatoxicosis. Sawhney et al (17) observed decreased egg production and hatchability in Japanese quail with aflatoxicosis.…”

The effects of aflatoxin on egg production, fertility, hatchability, and progeny performance were investigated by feeding dietary aflatoxin at dose levels of 0, 5, and 10 ,ug/g to mature broiler breeder hens for 4 weeks. Sixteen hens were used for each dietary dose level. Egg production decreased significantly during weeks 3 and 4 after initiation of toxin feeding for hens fed 10 and 5 ,ug of aflatoxin per g of diet, respectively. Whereas fertility was not affected by dietary aflatoxin, hatchability of fertile eggs decreased significantly within week 1 of toxin feeding. Hatchability of fertile eggs collected during week 1 of the treatment period was 95.1, 68.9, and 48.5% for the control, 5and 10-,ug/g groups, respectively. At the dose levels used in this study, no latent effects of the aflatoxin or its metabolites were observed on the performance of surviving chicks. Six hens from each experimental group were necropsied at the end of the 4-week treatment period. These birds exhibited typical symptoms of aflatoxicosis, including enlarged, fatty and friable livers, and enlarged spleens. Aflatoxin, produced by the fungus Aspergillus flavus, when present as a contaminant in
