Target growth rate standards for Holstein calves are:
• 24 hours to 60 days of age: Double birth weight
• 61 to 120 days of age: 2.2 lbs. average daily gain
• 121 to 180 days of age: 2.8 lbs. average daily gain

 “Plains

light weight
 Two-Phase Feeding Program – Grow to
700#, then increase energy
 Self Fed – Corn/pellet mix offered free
choice.

F.C. low quality roughage
How about Dairy Beef?
 Must
increase energy intake to accommodate
higher maintenance requirement (8-20%)
 Reaching a given fat end point prior to
achieving overweight discounts
 Holsteins have a higher proportion of bone to
muscle, affecting dressing percent
Implants
 What
do they do?
Increase dry matter intake
 Increase average daily gain
 Improve feed efficiency
 Increase Rib Eye Area
 Decrease in marbling
 Increase prevalence of bullers and dark

Marketing Dairy Beef Steers
 My
primary experience relates to Holsteins
are dairies that are successfully
marketing Jersey and Jersey crosses
(more later)
 Packers prefer “calf fed, High Energy Fed
Holsteins.

Dairy Beef Marketing Points
 Experience
indicates that 350 -500 lbs. is
reasonable point to consider marketing
groups of Feeder Cattle
 Buyers want consistent “load size” groups
at Finish (32 head at 1450-1475 lbs)
 Finished Holsteins have better contract
options when marketed as “load Size”
groups
What feeders want in feeder
holsteins








Uniform groups (load lots)
Castrated (preferably knife castrated)
Defined vaccination program
Showing adequate condition relative to age
Good foot and leg conformation
Hair growth and free of ringworm and
pinkeye.
Complete De-horning
Ideal situation is to market privately
Intricacies with Holsteins
 Very
susceptible to environmental
challenges (mud, extreme cold, heat)
 Experienced feeders will say that holsteins
“stall out” at weights over 1300 lbs.
 10% “Fallout” on finished
cattle(management can improve this.
 Variable selection of feed (F.C. hay, etc.)
 Grade and Yield requirements on
contracts

Some Packers specialize in “high energy, calf fed

Usually priced on Live cattle – Basis
Grade and Yield requirements
Communication with buyers is important
Finished weight, age, and condition is important
Liver abscesses are common on long fed holsteins,
but can be managed.
No Horns (carcass bruising)
The hide plays a part in total value. Brands,
lesions, hair loss, can play a role in total value

Yield Grade — Yield grade is an estimate of
the percent retail yield of the four primal
cuts of beef (chuck, rib, loin and round). It
is also known as cutability.
Yield grade is based on the four traits: hot
carcass weight, fat thickness at the 12th rib,
Internal Fat, and ribeye area
In general, Holsteins have smaller Ribeye
Size, OK on 12th rib fat, but have higher
internal fat which deters from Yield Grade.
Beta agonist seem to help on Ribeye size
