September 9/Agriculture Week -- According to a U.S. study, "Three experiments were performed to determine the effect of conjugated linoleic acid (CLA) on embryonic development in the absence of vitelline membrane disruption. In experiment 1, when eggs from control and CLA (0.5%)-fed hens were stored at 21 or 15 degrees C for 48 hours, mineral movement between the yolk and albumen was not observed (with the exception of Mg and Na)."
"Also, it was found that CLA-induced changes in yolk fatty acid content (e.g., increased saturated fatty acids and CLA) had begun to change after five days of feeding hens CLA, and no differences were detected in fatty acid composition after 14 days.
