katpau,
I would say you were correct... none of the benzimidazoles, Valbazen included, have any significant 'persistence'; I believe that slaughter withdrawal for Valbazen is, like, 5 days... so I'd certainly anticipate that deworming with it a week prior to AI or bull turnout would pose no issues, so far as teratogenicity is concerned.
Ojp6 - I have used Noromectin in the past, but studies showing that many of the 'generic' ivermectin products have efficacies far below that of the pioneer (original name-brand) product, have dissuaded me from using anything other than the 'real McCoy', anymore. If you'll give us a link to the study/PowerPoint you found, I'm sure several of us would be interested in looking at it and possibly commenting.
