Attempts were made to determine the effect of Diethylstilbestrol on cloacal gland, foam frequency and semen characteristics of male Japanese quail (Coturnixcoturnix japonica). The phytoestrogens present in the legumes and soy products affect the reproductive system of birds. Since, these compounds are found in various forms and very difficult to isolate it from feed, we used prototype estrogenic compound Diethylstilbestrol (DES) to study the effects on reproductive functions in adult male quails. In this study, 60 birds (8 weeks old) were randomly allocated into 4 treatment groups consisting of 15 birds each viz. T1, T2, T3 and T4. T1 and T2 groups served as control and vehicle control (olive oil) group, whereas group T3 and T4 were maintained as low dose (1 mg/bird/day) and high dose (5 mg/bird/day) treatment group, respectively. Diethylstilbestrol was administered orally to birds from 8ᵗʰ to 10ᵗʰ weeks of age. At the end of study, DES at both doses revealed significant (P<0.05) reduction in the area of cloacal gland and decreased (P<0.05) production of foam from male Japanese quail. Semen characteristics such as semen volume, sperm motility, live-dead and morphological abnormalities of spermatozoa and sperm concentrations was adversely (P<0.05) altered by DES administration. From this study, it can be concluded that Diethylstilbestrol has potent effect on cloacal gland, foam discharge, and semen characteristics of male Japanese quail.
