If requirements are not met, you have the option of supplementing with one of 2 brands of commercial cube. Cube A: 3.55 Mcal/kgDM and 25% CPDM; 88%DM; $350/ton Cube B: 3.01 Mcal/kgDM and 36% CPDM; 85%DM, $420/ton Use the simple algebraic method to determine which combination (Cube A + hay or Cube B + hay) is the least expensive to feed (remember: HAY is 90% DM and $60/ton). If you feed cube A, you will need to feed [akgdmh] kg DM hay and [akgdmc] kg DM Cube A. This will cost you $[costa]/head/day. If you feed cube B, you will need to feed [bkgdmh] kg DM hay and [bkgdmc] kg DM Cube B. This will cost you $[costb]/head/day. It will be cheaper to use Cube [ab] (A or B) to fulfill your cows’ nutrient requirements for energy and protein. (Numerical answers. Do not label. Round to nearest hundredth or penny. Use leading zeros.

Your cows weigh 1300 lb and are offered a free choice brome round bale. You assume that each cow is consuming 3.0% of her BW/day on a DM basis.  In reference to the previous question, each round bale weighs 1300 lb (AF). How many round bales do you need to get your 20-cow herd through the winter (4 months, assume 30d/month)?

The next 4 questions go together and use this same information. Your friend, Jim Halpert, needs to figure out the cheapest source of energy to feed his livestock. Please calculate the relative energy value of the following feeds and determine the least expensive option.   The oats cost $_______/mcal. Show and label your work on the file upload but just provide a numerical answer here, rounded to the nearest thousandth (3 decimals). Feed  Price/unit  Lb./unit  Mcal/lb.  Oats  $2.00/bushel  32 lb./bushel  1.32  Corn  $3.15/bushel  53 lb./bushel  1.54  Alfalfa  $200/ton  2000lb/ton  1.38
