Scrapie

• National Scrapie Eradication Program Goal
• Eliminate scrapie outbreaks by 2010
• United States be declared scrapie-free in 2017 by
  the Office of International des Epizooties (OIE)

3

• Scrapie Confirmed Cases in FY 2006
• Total - 244
• Kansas 5
• Infected and Source Flocks
• Total 77
• Kansas - 2

Differences between the scrapie premises ID
number (PIN) and the NAIS (PIN)

• NAIS Pin is based on the physical location where
  animals are housed.
• The scrapie Pin is based on whether a group of
  sheep is managed as a distinct unit with respect
  to disease risk and/or facilities scrapie program
  management.

5
National Scrapie Eradication Program and the
National Animal Identification System (NAIS)

• Utilize the existing national scrapie ID plan as
  a starting point
• Need to move from a visual ID system to an
  electronic system to achieve the NAIS tracking
  goal of 48 hours
• Develop a group/lot ID system for groups of sheep
  that stay together

6
Transition to NAIS

• Register premise with NAIS and then provide the
  NAIS Pin to APHIS
• Provide your scrapie PIN to the NAIS premises
  administration when registering so that it can be
  associated with your NAIS Pin
• Continue ordering USDA provided tags

Sheep Breeds

• Hair Sheep Breeds Dorper, St. Croix, Barbados
  Blackbelly, Katahdin
• Why?
• There is a shift in the sheep industry towards
  easy-care sheep that perform well under
  forage-based systems with limited managerial
  inputs, which are in line with the production
  traits of many hair sheep breeds.
• The phase-out of wool subsidies has made the
  harvesting of medium quality wools from typical
  form flock operations less economically feasible
  and shearing, in many instances, has become a
  major constraint.
• The proportion of lamb consumed by ethnic markets
  is steadily increasing. These markets generally
  prefer the leaner, lighter carcasses typical of
  hair sheep and their crosses.

8
Wool Situation

• Wool prices are at a four-year high
• Result of strong fundamental demand and a fear of
  a looming supply squeeze
• Australian wool production
• 1988-1989 Peak 2 billion pounds
• 2005-2006 1 billion pounds
• 2007 Forecast 924 million pounds
• China, the worlds largest wool consumer, has
  raised objections to Australias wool
  contaminated by medulated and dark fibers.
• China accounts for 62 percent of Australias wool
  exports.

9
Reproductive Management

• Reducing Seasonality of Breeding in Sheep
• Male introduction
• Breed differences
• MGA treatment - .25 mg/day in 2 feedings

10
Nutrition

• How can we get around high feed prices?
• Wet Milling and Dry Milling Products
