  1. Iowa Pork Congress 2004 Gilt Development & Lactation Length Influence on Born Alive Larry Himmelberg, M.S. January 28, 2004

  2. Gilt Development Maximizing Born Alive For P1 and Beyond Key Management Protocols Actual Producer Results

  3. Gilt Development • Key Management Protocols to Maximize BA • Background • Split Regarding P1 Born Alive • 10 to 10.5 vs 11.25 • Ask Questions of Customers • Size & Age Key Differences

  4. Gilt Development • Key Management Protocols to Maximize BA • Size/Age at First Mating • Prior Targets 265 & 6-7 Month of Age • Goal For 1st Mating=>ASAP • 98-99 Small Frame Issues • Mated off the Truck • Stunted Growth-High Replacement • Longevity • P1 Weight Loss

  5. Gilt Development • Which is Key Age &/or Size • Both • Age • 250+ Days • Weight => Frame Size • 320+ Pounds • Caution: Not All Genetic Lines!

  6. Gilt Development • Key Management Protocols • Get Back to Basics • 2nd or 3rd Estrus • Time Boar Exposure, Issue? • Flush • Be Mindful When Moving From Isolation

  7. Gilt Development • Key Management Protocols • Mating On Second Estrus+ • Boar Exposure • Physical Contact 8 to 20 Minutes/Day • Direct vs Fenceline • Record Gilts Expressing Estrus • Timing => ~ 25-46 Days Prior to Mating • Age Related? • Staleness

  8. Gilt Development • Actual Results • Be Results Oriented • Your Operation • Benchmarking

  9. Prod 1: Farrowing, 12 Months Prior to Gilt Development Strategy Implementation. Note BA is Below Benchmark Target

  10. Prod 1: Farrowing, 6 Months After Gilt Development Strategy Implementation

  11. Prod 2: 12 Months Prior to Gilt Development, Note P1 & P2 Below Benchmark

  12. 2002 Recs (Prev) • Age 220+ (200) • Size 290+ (265) • 2nd Estrus + (~50%, E1) • October ’03: >BA • Days > • Weight > • Flush • ***Feed Intake Prod 2: 12 Months After Gilt Development Strategy, P2 Problem

  13. P2 Reflecting, Gilt Development, Still Too Low • >P2 Similar • Herd BA Up .3 • Herd BA < BM Prod 2: Last 9 Months After Gilt Development Strategy Implementation, Note P2 & Some P3 Increase

  14. P2 Reaching Target • Herd BA Up .3 • Herd BA < BM, Later P Prod 2: Last 3 Months, Note P2 & Some P3 Increase

  15. 2002 Recs (Prev) • Age 220+ (200) • Size 290+ (265) • 2nd Estrus+ Prod 3: Excellent 11.4, But Parity 1 Opportunity

  16. P1 Goal, +.5 • P2 +.5 • All P => BM • WSC 27+ Feb 11, 03, Flush P1 Increase .5 Pig, PRRS Flare Up During This Time, All P Equal 11.7

  17. No Way to Max Born Alive w/o P1 &/or P2 Genetic Potential, 38% of Farrowings

  18. Customers: Look For Relationship & Benchmark Numbers

  19. Gilt Development Economics

  20. Gilt Development Economics(Per Month) • Assumptions • $36/7.5ft * 12ft = $57.60/12 = $4.80/Month • Feed $9/Month • Misc $.50 • Total $12.50/Month, Add to Gilt Cost

  21. Previous Lactation Influence on Subsequent Born Alive

  22. Top 10: 28.6 WA, 28.16 P/S/Y

  23. 5 Producer Average 1 Day = ~ .10 Pig BA, Matches Danish Numbers

  24. Can We Influence w/ Gilt Development? • Feed Intake ~ 4 Pounds Lower • Can Smaller Gilts Handle Longer Lactation Periods

  25. Previous Lactation Length Economics • Assumptions • Avg 1 Day of Lact Length = .1 BA • Number of Sows Equal

  26. Previous Lactation Length Economics • Farrowing Phase • Adding Crates, Reduces/Eliminates Economic Incentive? • Value in Subsequent Performance? • Adg, Death Loss, % Lean • How do you Calculate? • Fit the Model • At Least $1.25/Pig in Research Model

  27. Main, KSU Swine Day 2002

  28. Questions/Comments Thanks
