Antioxidant Use in Broiler Feeds

The efficacy of Endox®, 2,6-di-tert-butyl-4-methylphenol (BHT), and Ethoxyquin® for preservation of vitamin A was tested in three trials by placing four replicates of pelleted feed (ca. 27 kg each) in galvanized metal cans with tight-fitting lids. The vitamin premix used contained no antioxidant. After the feed was sampled, the cans were equipped with thermocouples and placed outside for 30 days. The data suggest that Endox® and Ethoxyquin® are equal in effectiveness and that both may be superior to BHT.
