  1. VDPAM 445Swine TopicsPart 0: Walk through Dr. Alex Ramirez Veterinary Diagnostic and Production Animal Medicine Iowa State University

  2. Currently, we are identifying the correct pig 60% of the time Generally, the tendency on many sites is to treat pigs that do not show signs of sickness On some sites, we fail to identify and treat pigs that are sick IDENTIFYING THE CORRECT PIG !

  3. Drugs and Dosage: • Use of the correct drug • Use of the correct dose amount • 88% of sites are using lower than the dose required for the drug to be effective • Importance of follow up treatments • Correct injection site

  4. Identification and Treatment

  5. Normal Rectal Temperature Ranges Weaned Pig: 102.1 - 103.1o F Growing Pig: 102.2 - 103.2o F Finishing Pig: 101.8 - 102.8o F

  6. Normal Respiratory Rates Weaned Pig: 25 - 40 breaths / min Growing Pig: 30 - 40 breaths / min Finishing Pig: 25 - 35 breaths / min

  7. How to evaluate a ROOM /BARN of pigs

  8. STOP ! LOOK ! LISTEN ! EVALUATE : Environment Pig Comfort Feed Delivery Water Supply

  9. Video 1 • Video 2

  10. How to evaluate a PEN Nursery and Finisher

  11. Use a systematic approach ! Do it the same way every time ! EVALUATE : Pig Comfort Pig Health Waterer position / flow Feeder adjustment

  12. Video 3 • Video 4

  13. Environment: Are the pigs comfortable? Are they cold (piling)? Are they hot? Are there drafts present? Think about the environment from the pig level, not yours!

  14. Water supply: Are the nipples at the proper height (top of the shoulders)? Is the water flow appropriate? 1.5 - 2.5 pints / minute (nursery) 1 - 1.5 quarts / minute (finishing)

  15. Water Flow

  16. Measuring water flow rates: Nursery: 1.5 - 2.5 pints / minute (25-40 seconds to fill a pint container) Finishing: 1 - 1.5 quarts / minute (finishing) (20-30 seconds to fill a pint container)

  17. Nipple Height

  18. Feed supply: Are the augers operating correctly? Are the feeders adjusted properly? Is the feed in the feeder trough free of mold and manure?

  19. Feeder Adjustment Good Wet Feed Excess Feed

  20. The pigs CAN tell you how they feel !! How do these pigs feel ?

  21. How the pigs feel is determined by: Not only the temperature but the combination of humidity and the air speed (drafts) with the temperature !

  22. Video 5 • Video 6 • Video 7

  23. What are these pigs telling YOU ?

  24. They are chilled either because they are sick or the barn is too cold or drafty

  25. 5 Most Common Symptoms • #1 CNS (strep) • #2 Lameness • #3 Diarrhea • #4 Pneumonia • #5 Off Feed

  26. EARLY INFECTION Treatment NOW is more EFFECTIVE Video 8Video 9

  27. Slightly more advanced "Dog Sitting" Treatment NOW is more EFFECTIVE Video 10

  28. More advanced Treatment NOW may still be EFFECTIVE Video 11

  29. ADVANCED Treatment NOW most likely TOO LATE !! Video 12

  30. Early , Mid, and Late Stages Video 13

  31. # 2 LAMENESS Lameness and Swollen Joints

  32. Both rear legs have swollen joints Notice that the pig stands with the rear legs more under its body than normal pigs to try to take weight off of the joints that are painful. Video 14

  33. Pig with swollen joints on the left, normal pig on the right. Notice the differences in the pigs posture and movements. Video 15

  34. This swollen joint is warm to the touch, soft and fluid filled. Video 16a

  35. Finishing Pig Not Lame with Firm, swollen joints = Recovered infection or injury No treatment !

  36. This pig can't compete with other pigs for food and water! It must be pulled!

  37. #3 Diarrhea

  38. Diarrhea in a Nursery Pig Video 18

  39. # 4 PNEUMONIA "THUMPING" or Labored Abdominal Breathing

  40. Notice how this pig is using its abdominal muscles to breath! Not just the muscles of the chest. This is a THUMPING pig! Video 19

  41. Increased respiratory rates due to causes other than pneumonia usually don't use the abdominal muscles like this pig. This pig has pneumonia ! Video 20

  42. # 5 OFF FEED LOSS OF BODY CONDITION

  43. Notice the pig's backbone just beginning to show. Just beginning to lose body condition from not eating. Video 21Video 22

  44. OTHER SYMPTOMS • Tail Biting • Navel Sucking • Greasy Pig

  45. TAIL BITING Is this a primary or secondary problem ? Video 23

  46. This is most likely a secondary problem in this pig… It is not healthy… Loss of condition and depressed

  47. TAIL BITING (Finishing Pig) Is this a primary or secondary problem ? Video 24

  48. This is most likely a primary problem in this pig ....... It is healthy.. in good condition It may need to be pulled to keep it from getting worse!

  49. NAVEL SUCKING Video 25

  50. Possible causes of Navel Sucking: 1) Pigs that are weaned too early. 2) Improper environment causing pigs to be uncomfortable. The pig that is doing the navel sucking should be removed from the pen!
