Therefore, administration of White
Kwao Krua (Pueraria mirifica, PM) containing potent phytoestrogen may influence serum lipid
components and egg yolk cholesterol. A randomized complete block designed experiment was conducted
using a total of 80, 18-week-old laying hens. The hens were equally divided into 4 groups receiving 4
different treatment diets containing PM at 0, 100, 500 and 1,000 ppm. Daily egg production was recorded.
Serum samples were collected at week 0, 2, 4, 6, 8 and 17 of the treatment for determination of lipid
components and estradiol. Egg samples were collected at week 4 and 8, yolk cholesterol was extracted
and measured. No significant differences in egg production pattern were found. At week 4 of the
treatment, the control group showed significantly higher serum triglyceride and total cholesterol levels
compared to other treatment groups (P<0.05), and a lower level of serum high density lipoprotein (HDL)
compared to the group fed 1,000 ppm PM fortified diets (P<0.05). Serum estrogen levels were found
significantly lower in groups fed PM fortified diets at week 8 (P<0.05) compared to the control. No
significant differences in egg yolk cholesterol levels were detected among the treatment groups. |
