| Abstract |
The main objectives of the present study were to determine the effects of administration of essemial phospholipids (EPL) on lipids and cholesterol content of egg-yolk One hundred and twenty, 36-week-old Gimmizah laying hens were randomly distributed into three equal groups and maintained in individual laying cages, throughout 16 weeks of the experiment.
Hens of the 2nd and 3rd group were injected subcutaneous with EPL twice a week at doses of 150 and 300 mg/kg BW, respectively, while the 1st group was injected with ethanol and served as control. Treatments continued for 12 weeks (from 36 to 48 week of age). Results showed that
1. Injection of 300 mg EPL caused a significant decrease in serum total lipids allover treatment period.
2. Injection of EPL significant!y decreased serum, cholesterol and triglyceride but significantly increased HDL.
3. Injection of 300 mg EPL was significantly decreased. .serum calcium at 44 week of age while GOT was significantly decreased at 44 and 48 wks of age, due to EPL injection.
4. High dose of EPL was more pronounced to reduce lipids and cholesterol in both yolk and liver.
5. Hatchability and abdominal fat were significantly reduced as affected by EPL injection, while, there was an increase in gall bladder volume.
6. Egg weight was significantly increased allover . treatment period as a result of injection 300 mg EPUkg BW, whereas body weight was only increased at 44 and 48 wks of age. .
7. At 40 wks of age, injection of EPL significantly increased egg number, egg production (%) and albumen weight percentage. This effect was disappeared after this period.
It was concluded that EPL injection to laying hens reduced total lipids and cholesterol in serum, egg yolk and liver especially high dose of EPL moreover, EPL injection had no adverse effects on layer performance except in hatchability trait.
