Calcium oxide shall be used in an amount not to exceed 5% (weight/weight) of the cereal straws or corn stover on a dry matter basis. It shall be labelled with the following statements: Caution/Précaution : \"Do not store feeds that have been treated with calcium oxide next to combustible materials. Do not allow calcium oxide to come into contact with incompatible materials (for example, acids, oxidizing materials and reactive halogenated compounds). To be stored in a sealed container after opening. / Ne pas entreposer les aliments pour le bétail qui ont été traités avec l'oxyde de calcium près de matériaux combustibles. Ne pas permettre l'oxyde de calcium d'entrer en contact avec des matériaux incompatibles (par exemple, des acides, des matières oxydantes et des composés réactifs halogénés).
