Iowa Pork Industry Center
The Iowa Pork Industry Center was established in 1994 as a coordinated effort of the colleges of Agriculture and Life Sciences and Veterinary Medicine at Iowa State University. Through partnerships with the IPIC, pork producers receive accurate and timely information to aid in making their operations more efficient and profitable.
We provide a variety of educational and informational opportunities for producers and the Iowa pork industry, ranging from issue focused workshops to large multi-topic events like Iowa State’s annual Iowa Swine Day. We work in partnership with commodity organizations, private industry and commercial businesses to deliver appropriate, timely and accurate resources.
The IPIC efforts are linked with the activities and programs of the ISU Extension and Outreach campus and field staff members, partnering on a variety of outreach opportunities. Swine specialists and faculty are available for discussion and consultation purposes in person, by phone and email. See our people page for individual contact information.

Abstract
Feeding the sow herd has direct and indirect influences on whole herd feed efficiency. Direct effects on sow herd feed efficiency should be analyzed by phase. Within each phase, sow weight gain (> 6:1 F/G), gilt developing gain (<4:1 F/G), and nursing pig gain (<3.5:1 F/G) have very different feed efficiency ratios and value of gain. Indirect influences on whole herd feed efficiency are dependent on the quality of the weaned pig. A larger and healthier weaned pig will have lower morbidity, mortality and faster growth rate influencing wean to finish feed efficiency
