Trial Options

Pen weigh dates for trials are flexible and dependent on protocol and needs.​ Feed inventories taken at weigh dates according to protocol. Feeders normally measured, but typically vacuumed at younger ages. Carcass data collected on all pigs and provided at no extra cost.

Pigs sourced via Gourley Brothers wean pig contract, which is a 5,000 head sow farm.



Wean to Feeder

Pigs arrive at weaning (about 21 days of age at about 13 lbs body weight) and stay for approximately 6 weeks or until they're about 55 lbs body weight.


Feeder to Finish

Pigs start at about 55 lbs body weight and are on trial until marketed (about 290 lbs).  Note: There is typically a nursery trial conducted the 6 weeks prior to the start of the Grow-Finish trial.  Nursery treatments are randomized across Grow-Finish treatments.


Wean to Finish
