Abstract/OtherAbstract:
|
1. The reduction in egg shell strength in hens at the end of the first reproductive cycle was not associated with abnormal uterine or body fat accumulation. 2. The phosphatidylcholine concentration was greater in the shell glands of hens producing strong egg shells compared to that of producing weak egg shells. 3. Differences were not detected in the total lipid or cholesterol concentrations or the fatty acid profiles of phosphatidylcholine or phosphatidylethanolamine fractions. 4. Following an induced molt, the fatty acid profile of the total lipid fraction of the shell gland was altered with a decrease in stearic acid and an increase in oleic acid. 5. The results demonstrate that alterations in egg shell strength are mainly associated with changes in shell gland phospholipid polar head group composition and not with changes in phospholipid fatty acid profile or cholesterol concentration. |
