According to the growth and development law of lambs and different contents of energy, protein, mineral substance and vitamin in various kinds of feedstuff, the feedstuff is mixed in certain proportion through scientific matching calculation and used in cooperation with byproducts such as straw, and then quick lamb fattening is achieved.

The present invention discloses to feed mulberry and feed ramie mixed complete materials for a beef cattle, and relates to the technical field of feeds. The mixed complete materials consist of the following raw materials in percentages by mass: 10-15% of feed mulberry powder, 0-10% of feed ramie powder, 0-5% of pennisetum purpureum powder, 0-5% of sweet sorghum powder, 40-50% of corn flour, 0%-15% of soybean meal, 5%-15% of wheat bran, 5%-12% of dry distillers' grains, and 3%-8% of beef cattle premixes. The raw materials are crushed, the crushed raw materials are screened, the screened raw materials are mixed, the mixed raw materials are stirred evenly, the beef cattle premixes are added, an appropriate amount of an antioxidant is added, the mixture is stirred evenly to obtain the mixed materials, the mixed materials are granulated into granular materials, the granular materials are finally cooled, and the cooled granular materials are dried to obtain the finished products. The feed is mainly used for the breeding and fattening of the beef cattle in a growing and fattening period, can significantly reduce the use amount of grain protein powder and reduce the culturing costs under the conditions of ensuring no reduction of production performance of the beef cattle, can also balance the structure of daily grains, and reaches the effects of improving daily weight gains, improving slaughtering rates, and shortening the fattening effects in a fattening cycle.
