| Abstract: | OBJECTIVEDifferent ammoniate methods were used for corn straw in order to improve its nutritive value.METHODThen the straw were fed the heifer to study its feeding effects.RESULTSThe result showed that:the CP content,DMI and ADG of the corn straw treated with multi-ammoniated increased by 124.25%,22.26% and 56.25% than control group respectively,the feedstuff cost(per kg gain)decreased by 15.63% than control group.CONCLUSIONIt was recommended to extend multi-ammoniated corn straw so that accelerating the development of cattle industry. |
