Vegetable protein meals may replace some of the grain in the case of low protein grains, especially for young cattle. Normal feedlot rations contain about 4% additives (which are premixed), 10% roughage and 86% grain. Secondly, an estimate of the likely inclusion of each ingredient must be made. This depends largely on what lot-feeders have on-hand, the availability of ingredients and current prices. Initially, the ingredients to be used in the feedlot ration must be selected. Processing roughages aids in the handling, mixing and stability of diets. Processed grain increases the metabolisable energy (ME) content and, therefore, the liveweight gain and feed conversion efficiency. In most cases, grains and roughages (hays) need to be processed. Grain must be increased slowly and roughage correspondingly decreased so that the gastro-intestinal tract has an opportunity to adapt to the increased grain (starch) content of the diet. Roughage has an important role in the introductory period. Currently, nil-roughage feeding systems are rare, but may be used for self feeders. After the initial induction into the feedlot, the ration gradually changes, increasing the amount of grain and decreasing the amount of roughage. A grain/roughage diet can generally be fed at 75:25 to 80:20, giving satisfactory weight gains at minimum risk, although this ratio can vary from 50:50 to 90:10. The majority of cattle feedlots feed high grain diets normally with roughage and with a number of additives fed as a premix. Generally, commercial lot-feeders engage a nutritional consultant to formulate diets based on available commodities. Formulation of the diet depends on the beastвЂ™s nutrient requirements for a desired level of performance, the nutrient content of feeds and the price and availability of the feed. Demands on feedlot cattle for production and economic performance require that a balanced, nutritious diet be fed.

To make a 400 pound batch, 300 pounds corn is mixed with 100 pounds soybean. Using this calculation, for every 30 pounds of corn 10 pounds of soybean should be added. Using the results: For the above example a ratio of 3 parts corn to 1 part soybean is calculated. For soybeans the entry will be soybean as the concentrate's name and 37 as the concentrates's percent. Enter the concentrate name in the box the and concentrate percent in the box for the concentrates's percent. Step 3: Choose a protein concentrate or another grain from the column on the left side of this screen, or choose something not listed. For roasted soybeans the entry will be Roasted Soybean as the grain's name and 37 as the grain's percent. Enter the grain name in the box for the grain's name and the and grain percent in the box for the grain's percent. Step 1: Choose a grain from the column on the left side of this screen.
