These guidelines are not exhaustive and are for guidance purposes
only.
1 |
All prescription-only
medicines should be prescribed by the farm veterinarian. |
2 |
Only use medicine
concentrations and combinations as recommended by the farm
veterinarian. |
3 |
- Maintain a good
record system to keep track of medicated feed usages.
- Medicated
feed usage must be recorded in the medicine book.
|
4 |
Purchase feed from
reputable feed agencies who maintain adequate measures to
eliminate in-feed medicine cross-contamination. |
5 |
Clean out or flush:
feed bins, conveyors, and feeding equipment to reduce medicine
carry over into the next load of feed. |
|
Figure 1. Augers often leave residual feed
in their housing because the screws must have clearance as shown
in figure on the right. The residual feed in represented by the
shading.

|
Figure
2. Movement of feed out of a bin occurs directly above the
discharge point. The remaining feed then cascades down the slope
of the crater that is subsequently formed. Failure to completely
empty bins before refilling will result in residual feed
retained in the bin. |
|
Figure
3. The figure to the right
demonstrates the typical feed flow in a feed bin, with shaded
areas illustrating where the feed is most likely to remain and
contaminated the next batch. |
|
Figure
4. Feed hoppers may also have
residual feed if not properly managed. Ensure that feeders are
completely empty before refilling. The figure on the right
demonstrates the typical feed flow in a feeder with potential
areas of residual feed remaining between batches. Note: each
feeder design will be different. Use bagged feed to assist the
cleaning out process. |
7 |
Adhere to proper
withdrawal periods for medicines. |
8 |
- Prevent recycling of
medicines via manure and urine by adhering to cleaning
procedures between groups of pigs.
- Prevent slaughter pigs from
having access to urine and feces from medicated pigs.
- Note where feed barrows are used to transport pigs.
- Note sows who
have gained access to medicated creep feeds.
|
9 |
Where possible use
bagged feed for medicated feed and label all feed bins where
medicated feed is kept. |
10 |
Read and follow any
guidelines provided on all medicine products. |
