Effects of Dandelion (Taraxacum officinale) Supplementation on Productive Performance, Egg Quality Traits, Serum Biochemical Parameters and Liver Fat Rate in Laying Hens

Background: This study was conducted to investigate the effects of dandelion (Taraxacum officinale) root supplementation on performance, egg quality and some serum antioxidant enzymes capacity with increasing age, after peak laying stage in hens. study, also aimed overcome diseases that occur due lipid metabolism layers late period. Methods: In total, one hundred twenty 70-week-old Lohman LSL hens were randomly assigned five groups equally (n = 24). Each treatment replicated six times (6 replicates x 4 birds). The control group fed basal diet (2650 kcal/kg ME) no supplementation. other high-energy diets (2850 induce fatty liver 5, 10 15 g/kg (taraxacum supplemented. Result: revealed addition 5 feed positively changed production, decreased profiles (triglyceride VLDL) fat ratio played a role preventing peroxidation.
