Abstract
The objective of this study is to investigate the effects of active folate on egg
productive performance and egg quality of laying hens. 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.
