Effect of dietary erucic acid on the utilization of oils or fats by growing chicks. 1985

J S Sim, and B Toy, and D C Crick, and D B Bragg

Free erucic acid (EA) (C22:1) was blended with Cambra oil (CBO), sunflower oil (SFO), and animal lard (AL) at 45% (w/w). Six experimental diets were formulated to incorporate either CBO, SFO, AL, or EA blended oils (CBO plus EA, SFO plus EA), or fats (AL plus EA) at 8%. The adverse effects of dietary EA blended with various types of oils or fats were studied by feeding 180-day-old White Leghorn cockerels for a 4-week growing period. In general, adverse effects of dietary EA were clearly reflected in feed consumption, chick growth, and apparent digestibility of total lipids as well as individual fatty acids. The AL plus EA produced significantly greater adverse effects than with SFO plus EA. The diet containing CBO (low EA, 5.1% rapeseed oil) depressed chick growth and feed consumption, but no additive effect was manifested when EA was supplemented. The fatty acid profile of dietary SFO appears to counteract the metabolic burden of excess dietary EA. It was concluded that high linoleic acid content in SFO may be the major contributing factor in alleviating the adverse response to EA.

D009821	Oils	Unctuous combustible substances that are liquid or easily liquefiable on warming, and are soluble in ether but insoluble in water. Such substances, depending on their origin, are classified as animal, mineral, or vegetable oils. Depending on their behavior on heating, they are volatile or fixed. (Dorland, 28th ed)
