Analysis of DOW CORNING Antifoam A Compound in feed was conducted on three rabbit feed mixtures that were formulated by Ralston Purina with 0.5%, 1.0% and 2.5% DOW CORNING Antifoam A Compound, Food Grade. Four sets of samples were collected. The first set was on the first shipment, the second set was on the second shipment, the third set was at the end of the first shipment, and the fourth set was on feed that had been in the feeder for two days. Each sample was analyzed for composition and distribution of linears and cyclics of the test chemical in the feed. The test results indicate that no significant amounts of DOW CORNING Antifoam A Compound was lost by evaporation during storage or while in the feeders. There was no significant difference in distribution of linears and cyclics between pure DOW CORNING Antifoam A Compound and the DOW CORNING Antifoam A Compound that came from the refrigerated and unrefrigerated feed. Consequently, the results of the study indicate the feed was properly prepared and that the integrity of the feed mixtures was maintained during the study.
