1
Goat Diseases
  •  Parasites- #1 problem in KY
    • Worms
    • Haemonchus - barber pole worm
    • Reduce Resistant Population by:
    • Isolate new additions to herd
    • Fecal Egg Reduction count , de-worm, wait 10 days egg count reduce by 90%
    • Use cocktail dewormer (From 2 different classes)
2
Strategic Parasite Management I
  • De-Worm –Keep Worm Eggs Off Pastures
    • Spring, first pasture contact,  each 3rd week 3 consecutive times


    • Two weeks prior to breeding


    • Winter,3 – 4 weeks prior to kidding, or just following kidding


    • Fecal egg count herd monthly during grazing season and ID = egg carrier animals




3
Strategic Parasite Management II
    • De-worm
    • Only goats with high fecal egg counts 50 – 100 eggs/gram of feces


    • Dry lot infected animals for 48 hrs before allowing on pasture.
      • Fast 12-24 hrs before
      • Deworm 8-12 hrs after
      • Improves contact time
      • Drop fecal material and eggs on dry lot

4
Strategic Parasite Management III
    • Deworm
    • Three weeks after major rain


    • Rate is 2 X cow rate except for Levasol at 1.5 X cow rate


    • By mouth only


    • Based on the heaviest animal in the herd

5
Strategic Parasite Management IV
    • Pasture rotation: 3 months off (dry, hot)


    • Pasture rotation: 6 months off (cool, moist)


    • Dilution by grazing cows and goats or cows following goats


    • Move goats forward each 7 – 10 day, leaving fecal material and parasites behind and do not graze regrowth



6
Strategic Parasite Management V
    • Graze regrowth with horses, cows, steers or make hay


    • Graze high or browse (Move goats off perennial pastures onto up-right growing annuals)


    • Most importantly, avoid grazing goats close to the ground

7
Summer Grazing Techniques for Parasite Avoidance
8
Tools of the Trade
  • Treatment decisions made from counting parasite eggs in fecal material
  • Eggs/gram Feces
  • FAMACHA

10
"Stage 3 larvae contained in..."
  • Stage 3 larvae contained in water droplets waiting to be consumed by grazing ruminant.

12
Choice of a De-wormer
  • Choose one product, use for at least a year or until it stops working
  • Do  fecal egg counts if suspect resistance*


  • Change to another drug CLASS when change is need
  • Avoid using Cydectin as long as possible



13
Classes of Dewormers
14
Prevention of Coccidiosis
  • Monensin – Rumensin - Approved 15-20 gms/Ton **
  • Lasalocid – Bovatec – E Label 20 – 30 gms/Ton
  • Decoquinate – Deccox – Approved .5lbs/Ton **
  • Amprolium – Corid – E Label 20-25 mg/kg in feed 5 days, 5mg/kg PO for 21 days *
  •  * Prolonged use may cause Thiamine Deficiency
  • ** Approved by label


15
Prevention of Coccidia Infection
  • Cultural control is the best control


  • Restrict access to feed, water and hay by designing facilities to limit fecal contamination
