Leghorn laying hens of 35-week old were separated into three groups fed with corn-soybean basal diet and supplemented with oxidized or reduced form of folate. The experimental period lasted 8 weeks. Eggs and blood were collected for samples at two week interval. Plasma and egg yolk folate levels were determined by high-performance liquid chromatography with fluorescence detector. Fatty acid compositions of plasma and egg yolk were also analyzed. Folate contents in plasma and egg yolk of folate supplemental hens were significantly higher. The egg productivity in the reduced and oxidized folates were 96.59% and 94.22%.These were significantly better than 88.93% in no folacin supplemental group. Changes induced by folate treatments on fatty acids of egg yolk were no difference. But n-3 PUFA increased with folate addition. |
