What's happening in this photo? 🤔
Iowa State University Extension and Outreach swine field specialist Colin Johnson is using ultrasound imaging to measure a pig's loin size and backfat depth.
Each summer, swine field specialists assist with carcass value contests at swine exhibitions across Iowa. This is an opportunity for 4-H and FFA youth and their families to learn about their pig's performance and how the industry determines pork cutout values and pricing.
How is the final carcass value determined? 🐷
The pig's starting and ending weight, along with total days on feed, are entered into a pricing matrix. Premiums are determined on a sliding scale for the ideal backfat and loin size parameters based on each individual pig's measurements at the 10th rib loin muscle area.
Finally, today's market values for pork cuts are incorporated into the equation to determine the final performance ranking. Top individuals are then recognized for their highly efficient pig! 🏆
