A 4-year-old Holstein dairy cow in peak lactation is losing bodyweight at a faster rate than desired. The farmer has asked for yourhelp in rebalancing the cow's ration. The cow needs a ration thatprovides 2.65 Mcal/kg of metabolizableenergy. The feed will be provided as a total mixed ration (TMR)with the forage/roughage mixed with the concentrate, and at least50% of the TMR needs to be forage/roughage for rumenhealth.
Which forage/roughage would you recommend for the newration?
a.Hay (cool-season grasses)
b.Hay crop silage (cool-season grasses)
c.Legume hay
d.Legume hay crop silage
e.Sorghum silage
f.Corn silage
Which concentrate would you recommend for the newration?
a.Soybean meal
b.Cotton seeds
c.Dried distillers grains with solubles
d.Corn and cob meal
e.Ground shell corn
f.Oats (rolled)
3. Using your selected forage and concentrate, balance theration on a DM basis for this cow. You can either use the PearsonSquare or Equation technique (with no fixed ingredientsneeded).

4. Your cow should be eating a total of 50 lbs of dry matter.Using this intake amount, now convert your ration to an AS-FEDbasis. This will inform the farmer as to how much forage vsconcentrate to use when mixing his total mixed ration.
