摘要: Two commercial cottonseed meals, a direct solvent-extracted meal and screw-pressed meal, were subjected to successive solvent-extraction procedures by using an acetone/hexane/water azeotrope reduce their cyclopropenoid fatty acid content. The two original as well double- triple-extracted portion, then incorporated at 20 wt % levels in the rations of laying hens. A negative control containing 25% soybean positive con-trol 2 refined oil known CPA content also employed. During four-week feeding period eggs collected dur-ing third fourth week stored 35F for periods three six months. Over-all egg quality distribution extracted yolk lipids determined after three- six-month storage period.
