6. The Change Imperative
“When the rate of external change
exceeds the rate of internal change,
the end of your business is in sight.”
Jack Welch, CEO General Electric
7. USA Swine Industry
Production Structure
• Traditional
– Family farms owned sows and land
• 60 to 200 sows
• Two farrowings per year
• Manure applied to land
• Seasonal labor
• 2012 – new
– Wide variety of ownership and size
– Sow farms larger
• 1,000 to 5,000 sows breed to wean (for health reasons)
• Wean 500 to 2,400 pigs per week
– Nursery Finisher or Wean to Finish
• All in / All out
17. Disease
• Respiratory
– PRRSv
– SIV
– Mycoplasma
– Circovirus
– Bacterial (the suis’s)
• Strep suis
• Actinobacillus suis
• H. parasuis
18. PRRSv ($5 - $7 / pig)
• Objectives
1. Produce and deliver negative pig
• Vaccinate if delivered to high risk area
• Leave unvaccinated if in low risk area
2. Deliver a PRRSv positive vaccinated piglet
• Utilize an PRRSv MLV vaccine
• Tools
– Location
– Prevention (filters)
– Elimination
19. Mycoplasma / Circovirus ($2 to $7)
• Objective:
– Sow farms + / -
– Deliver pigs that are vaccinated and ready to grow
23. Salmonella
• Stress and contamination disease
• Objective:
– Mitigate stresses on pigs causing the clinical
disease
• Control
– Vaccine for Salmonella Choleraesuis
– Feed medication and or vaccination for Salmonella
Typhimurium
30. Research and Information historically
• Information
– PigCHAMP
– Grow – Finish
• Spread sheets or custom
• Research
– On farm trials
• Has limitations
– Relationship with Universities
• Vendor research
31. Pipestone Research Committee (2009)
• Director – Dr. Scott Dee
• Members
– Dr. Joel Nerem
– Dr. Spencer Wayne
– Dr. Cameron Schmitt
– Dr. Barry Kerkaert

– Dan Hanson
33. Perspective on research
• New products
– Supported by data
• Avoid internal bias from experience
• Limitations
– Research vs. commercial out come (70%)
– Information from other systems / sources
• Value
– Creation
– Intellectual property
41. Trial Objective
• To determine if Enterisol® Ileitis vaccine performs
better than Tylan® feed grade in a step down
program as a way to control the effects of a Lawsonia
intracellularis infection.
• A pen level study with the primary parameter being
feed efficiency (FE)
42. Materials and
Methods Trt Trt Name Treatment Group Description
40 pens of 26 pigs vaccinated with Enterisol Ileitis at day 0
Enterisol and fed 10 grams Stafac per ton starting on day 40 until day
•Trial conducted at 1 Ileitis/Stafac 120.
Pipestone Vet Clinic 40 pens of 26 pigs fed 100 grams of Tylan per ton from day
research barn from 6- 40 to day 58, followed by feeding 40 grams of Tylan per ton
2 Tylan until day 120.
28 to 12-19, 2011
• 2080 weaned pigs
from 2 sister sow
farms in the Pipestone
system.
•Pigs weighed and
allocated to two
treatment groups
43. Materials and Methods
• 2-3 pigs per pen (10% of
population) were inoculated
with Lawsonia intracellularis
gut homogenate at log 4.5 x

46. Conclusions
• A Lawsonia intracellularis seeder challenge model is
possible in a large scale commercial study.
• Pigs on the Enterisol Ileitis/Stafac program had a 2.9%
improvement in FE (P<0.05)
• Total return on investment favored the Enterisol
Ileitis/Stafac group by $3.05.
• Today
• $0.25 + $3.76 = $4.01 (vaccine and Stafac)
