Özet:

 

This study set out to determine the effects of dietary supplementation of grape seed oil and Hypericum perforatum L. extract to the laying hens (Lohmann White, 40 weeks of age) on performance, egg quality and some blood parameters. For this purpose, a total of 336 hens were randomly distributed to the control and other treatment groups, 12 replicates/group with 4 hens/replication. Birds were fed with basal diet only (control group) and the basal diet supplemented with different levels (100, 200, 300 mg/kg) of grape seed oil (GSO-1, GSO-2, GSO-3) and Hypericum perforatum L. extract (HPE-1, HPE-2, HPE-3). Dietary treatments had no significant effect on performance parameters. GSO-3 and HPE-1 supplemental groups presented with increased shell weight (p<0.01) while only GSO-1 group showed increased egg albumen index (p<0.01) and Haugh unit (p<0.05). Among blood parameters, except for serum HDL and total protein, the other blood parameters (serum triglyceride, total cholesterol, LDL, AST, Ca and P) were not affected by the treatments. In conclusion, results showed a partial improvement in some egg quality traits, however, further studies are needed to fully investigate the beneficial effects of these additives in laying hens reared under different stresses. .
