Hello Mike,
The withdrawal time for Tramisol largely depends upon the "type" of bolus it is as there are quite a few; primarily for swine, cattle and sheep. From what I have found, Tramisol contains Levamisole Hydrochloride. This is the residue that you are trying to avoid. While I have found nothing specific to "withdrawal time" for milk, it does indicate withdrawal times for slaughter and - "Not for use in dairy animals of breeding age." All the Tramisol products should carry that warning on the label.
For Tramisol & Tramisol Type A (swine & cattle), there is a 3 day withdrawal time (for swine, 2 days for cattle) before slaughter Nothing is mentioned about milking - however it is clearly stated - "Do not administer to dairy animals of breeding age".
Tramisol Gel - 6 day withdrawal time to cattle, sheep or swine. Again - Do not administer to dairy animals of breeding age.
The other Tramisol products all indicate the same.
There is a specific Tramisol paste called "Tramisol®-X-Tra Cattle Anthelmintic and Extoparasitic Paste" - this one has a 19 day withdrawal time.
The boluses are generally of two types - sheep and cattle. The sheep boluses have a 3 day withdrawal; cattle 2 day. 1 bolus per 50 pounds (sheep). Again - "Not for use in dairy animals of breeding age."
I had looked at using Tramisol as a wormer for our goats and asked many people about this. Quite a number of people wrote back and told me that it is a "dangerous" wormer unless you can correctly dose it. That is, if you are "guessing" the weight of your goats, you risk a chance of overdosing them. One side effect is that they foam from the mouth a bit.
The majority of this information came from the US Code of Federal Regulations.
Hope this helped. Best regards,
