Fall 2022
1) You are the manager of a large, purebred Hereford operation. You purchased some
390 day old heifers that weighed 660 pounds (average). You have estimated that
these heifers should weigh 1200 pounds as mature cows. You want to breed them at
450 days (15 months) of age. Knowing that heifers should be approximately 65% of
anticipated mature weight at breeding, formulate a diet that will have your heifers at
the appropriate weight for breeding at 450 days (15 months) of age. Provide adequate
protein, energy, Ca, and P. You have an unlimited supply of johnsongrass (sorghum
halepense) hay from your farm. You have corn available on the farm. You can buy
cottonseed meal (IFN 5-01-617) and minerals from the local feed mill. Use NEg.
