One hundred and twenty 10-weeks-old quails were allocated to four dietary treatments. Quails were caged individually and fed diets supplemented with 0 (control), 1, 2, 4% garlic powder for 12 weeks. There were significant (P < 0.05) differences among the diets in feed consumption, feed efficiency and egg production as averaged over 12 weeks. The better values for these parameters were obtained from the 1% garlic powder supplemented group. Garlic powder addition did not significantly affect egg yolk index, egg shell weight and egg shell thickness. However, there were significant differences (P < 0.05) in egg albumen index, egg shell index and Haugh unit. There was a significant (P < 0.05) reduction in the egg yolk cholesterol concentration when the dietary level of garlic powder was increased from 0 to 4 g/kg. Plasma high density lipoprotein (HDL) cholesterol concentrations increased (P < 0.05) with increasing levels of dietary garlic powder. Plasma cholesterol (P < 0.05) and triglyceride (P < 0.05) concentration decreased with garlic powder supplementation. It was concluded that garlic powder in the diet of laying quails reduced the plasma and egg yolk cholesterol concentration.eninfo:eu-repo/semantics/openAccessgarlic powderlaying quaillaying performanceegg traitsserum parametersArticle55728629310.17221/126/2009-CJAS2-s2.0-77955640579Q2WOS:000281108900003Q2
