Figure B - Hoop Barn as a "Tail-Ender Barn

Note: Assumes that fees associated with facilities, utilities, repairs, interest, taxes and net return are on a pig space per year basis. Fees associated with bedding, veterinarian and medicines are on a per pig basis.

Removal of 15% "Tail-Enders" increases number of turns
in total slat Grow-Fin Facilities

Facility Charge Utility Cost RIT Turns Vet&Med Mort.(%) ADG(lbs) FE(lb.f/lb.g) Net Return
$30.00 $1.50 $2.00 2.86 $0.40 1 1.7 3.1 $10.15
$30.00 $1.50 $2.00 3.10 $0.40 1 1.7 3.1 $15.00

* Improvement of $4.85/pig space would mean that the sort would have to be <$O.71/cwt

Additional assumptions include:

  1. At the end of 118 days all hogs weighing 260 pounds are sold and the expected 15% weighing an average of 220 pounds are then transported to a hoop structure;
  2. This reduces finishing days in the total slat barn from 128 days to 118 days;
  3. This will now allow the manager to turn the facility 3.1 times vs. 2.86 times.

The Profitability of placing the 15% "Tail-Enders" in a Hoop Structure is
dependent on the sort loss associated with the 220 pound hog

$10.00 $1.00 $1.00 $90.20 9.10 1.0 5.1 ($17.46)

Assumptions, same as note above in addition to:
  1. facility size of 200 head;
  2. market hog price of $42/head;
  3. 39 pounds of gain/pig with an ADG of 1.3 and FE of 5.1 (feed cost $140/ton);
  4. return to labor and management set at $24/pig space/year in the hoop barn;
  5. pigs fed an additional 30 days and 10 days allowed for clean up.
