NORTH CAROLINA STATE UNIVERSITY EXTENSION SWINE HUSBANDRY
ON-FARM PERFORMANCE TESTING PROGRAM
The objective of the On-Farm Performance Testing Program is to
provide purebred and commercial swine producers with estimates
of the genetic value of their animals for growth rate, carcass
leanness, and carcass quality. This program is divided into two
- Individual Performance
- Growth rate, backfat thickness and loin eye area
- Carcass Quality
- Color, Marbling, pH and other data as requested/available
POLICIES AND PROCEDURES
Growth Rate, Backfat Thickness and Loin Eye Area
- Participating swine producers will be provided litter data
- Producers will complete the data cards as the litter information
- The producer must inform the technician of the farrowing dates
of each test group of litters.
- The technician will schedule a weigh date to weigh and ultrasound the test group when all litters in that group are approximately
154 days old.
- Weights will be obtained on scales provided by the breeder.
- Backfat and loin eye will be measured by real-time ultrasound.
- The weights and backfat and loin eye measures of each pig plus other required information
will be recorded on the data cards.
- The technician will transfer the completed litter data cards
to North Carolina State University for computer processing.
- A report will be prepared that will contain:
Three copies of the processed data will be printed and will

All program participants will be billed quarterly. The costs will
be based on an annual enrollment fee of $20.00. Additional charges
will be based on:
Growth Rate, Backfat Thickness, and Loin Eye Area - Real-Time Ultrasound and Carcass Quality
- $200.00 minimum charge per technician's stop. This will include
