Abstract: 【Objective】Different ammoniate methods were used for corn straw in order to improve its nutritive value.【Method】Then the straw were fed the heifer to study its feeding effects.【Results】The 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.【Conclusion】It was recommended to extend multi-ammoniated corn straw so that accelerating the development of cattle industry.
