ANSC 230 Ration Form by Substitution Substitution is stepwise process by which herbivore rations can be formulated. This method is very systematic...almost like a flowchart! If we think about the herbivore "food pyramid (see image), substitution will follow the pyramid! Start with the foundation ingredient (roughages) and add in other feeds to supply energy, protein and minerals/vitamins, as needed. ADDITIVES MINERALS/ VITAMINS PROTEIN (USUALLY 2ND LIMITING) ENERGY FEED (USUALLY IST LIMITING) ROUGHAGES (BASE) For these problems, carry to two decimal places (example 0.67 lbs) for all macro nutrients (DM, energy, protein) and carry three decimal places for minerals. For all feed amounts (pounds of each feed), carry to two decimal places. This will be important when students submit final answers on BB Learn! For these problems, you will be asked to convert the final DM pounds to as fed pounds! 1. Lamba Feedlots in central Nevada feeds out lambs for restaurants in Reno and Las Vegas. The lambs on average require 4 lbs of DM, 1400 kcal NEg, 0.65 lbs protein, 0.01 lbs phosphorus, and 0.02 lbs of calcium each day (absolute requirements). The feedlot uses ryegrass hay pellets (look up ryegrass hay; roughage source), wet potato waste (energy source; byproduct available in the region), corn gluten meal (protein), dicalcium phosphate (phosphorus) and ground limestone (calcium). Ammonium chloride is fixed at 0.5% of the ration DM (hint: how many pounds of ammonium chloride is 0.5% of 4 lbs of DM?). How many pounds of each ingredient is needed to meet a lamb's daily requirement? Report final amounts on an as-fed basis.
