| Summary: | This study was performed to evaluate the effects of folic acid (FA) and methionine (Mt) administration on egg 5-methyltetrahydrofolate (5-MTHF) content, levels of zinc in yolk and serum and concentration of homocysteine on Hy-line W36 hens from 20 to 26 weeks of age. The experiment was conducted as a 4×4 factorial arrangement of treatments in randomized complete design with four levels of Mt (0.25, 0.32, 042, 0.48 mg/kg of diet) and four levels of FA (0, 5, 10, 15 mg/kg of diet). Fortification of laying hens diets with FA 0, 5, 10 and15 mg/kg of diet increased 5-MTHF into yolk significantly (p |
