Exploiting stalk feed resources to develop animal husbandry is an important measure to solve efficiently the contradiction of forestry and animal husbandry in cross regions of rural area and pastoral area in the north loess plateau during soil and water conservation and economic balance construction. Corn stalk was blocked into feed block by blocking machine and fed beef. The result showed that the daily gain in mass of the beef fed with corn stalk is 24%～39% higher than that fed with corn silage, and the economic benefit was significant. It was also found that the feed block composed of corn stalk was cheap and convenient to store for a long period and to transport for a long distance. Therefore it will make a new way to develop saving grain typed animal husbandry and will play an important role for soil and water conservation.
