DOIAbstract
The sperm-egg interaction was investigated during their reproductive life, in laying quails mated with males of different ages (Coturnix coturnix sp.). The experimental design was completely randomized in factorial scheme 4 x 4 (age of the females of age x male quail, 80,160,240 and 390 days), with 10 replicates and six birds each, in proportion to two females for a male. The results showed that there was a quadratic effect (P <0.05) the amount of sperm trapped in the vitelline membrane of the germinal disc, depending on the age of the females, with a reduction of this number over the old. The age of the females had no effect on egg weight, shell thickness, the percentage of shell and yolk and Haugh unit. As for the egg production was a qua...
