Q. |
What is the impact of mange on the profitability of pig production? |
|
| |
A. |
The rubbing caused by mange infestation in growing pigs has been associated with decreases in average daily gain and feed efficiency up to 10%. In cases of severe mange, weight gain may be reduced up to 25%. Further losses at slaughter may occur through the need for trimming and possibly skinning of carcasses.

Q. |
How can you diagnose mange in sows? |
|
| |
A. |
A skin scraping of mites from the ears of a sow provides instant confirmation of mange. However, a number of ear scrapings may fail to reveal mites even in an infested sow herd.

Q. |
How can you diagnose mange in growing pigs? |
|
| |
A. |
To quantify the frequency of rubbing in the weaner/grower pens, a Rubbing Index (RI) has been developed to correlate the frequency of rubbing with degree of infestation. The number of rubbing episodes observed in a 15 minute period, divided by the number of pigs observed, generates the RI value. An RI value greater than 0.4 indicates a need to review mange control strategies.

|
|
| |
Q. |
Can pigs be checked for mange at slaughter? |
|
| |
A. |
Slaughter checks provide an opportunity to determine whether mange is affecting the growing pigs. A scoring system has been developed to correlate the number of small red skin lumps (papules that are the body's response to sarcoptic mange) with severity of mite infestation.

Q. |
What strategies are available for the reduction of mange in pigs? |
|
| |
A. |
Both control and eradication programs have been developed and a variety of strategies exist. Specialist advice from your consulting veterinarian or Merial Veterinary Technical Services will help you to design the most convenient and cost effective approach to your mange control program.
|
|
|
| |
Q. |
When is it the best time to control mange? |
|
| |
A. |
The warm and dry months create an environment unsuitable for prolonged survival of the mange mite of the pig. Such conditions provide an ideal opportunity to reduce mange.
|
|
|
| |
Q. |
How long will it take for payback on a mange eradication program? |
|
| |
A. |
Various authors have described a payback time for the cost of mange eradication to be between 7 - 12 months. Mange prevention and quarantine strategies must be implemented following successful eradication.
|
|
|
| |
Q. |
What products should I use for my mange control program? |
|
| |
A. |
The development of IVOMEC injection provides a new approach to the control of mange. IVOMEC injection is highly effective against mange mites located on the skin surface, or burrowed deep beneath the skin layers.
|
|
|
| |
Q. |
Does IVOMEC® Injection controls worms in pigs? |
|
| |
A. |
Yes, IVOMEC Injection controls the following internal parasites: large roundworm, red stomach worm, nodule worm, intestinal threadworm and whipworm. The board spectrum activity of IVOMEC makes it a good choice for the control of internal parasites in pigs of all ages.
