Seed from maize (corn) Zea mays provides a ready source of 9-lipoxygenase that oxidizes linoleic acid and Iinolenic acid into 9(5)-hydroperoxy-1 0(8, 12(Zl-octadecadienoic acid and 9(SJ-hydroperoxy-1 0(£), 12(Zj, 15(Zl-octadecatrienoic acid, respectively. Corn seed has a very active hydroperoxide-decomposing enzyme, allene oxide synthase (AOS), which must be removed prior to oxidizing the fatty...

Two experiments were conducted to determine the DE and ME content of corn distillers dried grains with solubles (corn-DDGS) containing variable ether extract (EE) concentrations and to develop DE and ME prediction equations based on chemical composition. Ether extract content of corn-DDGS ranged from 4.88 to 10.88% (DM basis) among 4 corn-DDGS samples in Exp. 1 and from 8.56 to 13.23% (DM basis...

In this study, the cutting force and energy requirement of corn (Zea mays L.) stalk at different internodes (diameter), from bottom to top internode positions for Pionner 2105, Pioner 1570, KWS MAY 75 varieties, were determined. The mean diameter varied between 11.28-19.00 mm bottom. Also, cob breakout requirements determined these varieties. According test results, varieties found statisticall...
