| ABSTRACT: Considering that neem (Azadirachta indica A. Juss.) causes deleterious effects on fertility, the objective was to evaluate the effect of feeding quail (Coturnix coturnix japonica Linnaeus, 1758) of 90 days old with neem seeds on seminal quality, biometric parameters, and testicular morphometrics, as an experimental model. After the 30 day adaptation period to the experimental conditions, birds were randomly distributed in five treatments of neem seeds incorporated into feed, with 10 replicates: T1 (0%), T2 (5%), T3 (10%), T4 (20%) and T5 (40%). After 60 days of receiving experimental rations, their semen was collected to evaluate the sperm quality, the birds were euthanized, and testes were submitted to biometric, histological, and... |
