1999
Kerti,A. | B rdos,L.
The effect of feeding retinyl acetate (RA) for 1 month on the retinol (ROL), retinyl palmitate (RP) and beta-carotene (BC) levels in the blood, testicles and ovarian follicles of 6 groups of adult Japanese quails, 6 weeks old (n=30 each), was studied.The basal diet (containing vitamin A at 10 X 103 IU/kg) was supplemented with 100 X, 500 X and 1000 X 103 IU/kg RA in groups I, II and III in both sexes.Plasma vitamin A rose in all groups.The elevations were caused basically by the RP fraction.The ROL concentration increased only slightly, indicating saturation of the blood binding/transport system.Plasma BC decreased in both sexes.RA feeding resulted in high RP concentration in the genital organs (testicles and ovarian follicles), indicating subclinical hypervitaminosis, while the BC content of genital organs decreased considerably.
