Why are you treating cattle this time of year?
Well for deworming I drench and pour both together, I bought some cows that were thin and pretty wormy so I was treating them.[/quote]
Every workshop or vet I ever talked to here say to treat Memorial and Labor and not after Labor day if they were not treated then.
The parasites are in stages after then that can cause problems from bloat to paralysis.
When to Treat Cattle with Grubs
IVOMEC Pour-On effectively controls all stages of cattle grubs. However, proper timing of treatment is important. For the most effective results, cattle should be treated as soon as possible after the end of the heel fly (warble fly) season. While this is not peculiar to ivermectin, destruction of Hypoderma larvae (cattle grubs) at the period when these grubs are in vital areas may cause undesirable host-parasite reactions. Killing Hypoderma lineatum when it is in the esophageal tissues may cause bloat; killing H. bovis when it is in the vertebral canal may cause staggering or paralysis. Cattle should be treated either before or after these stages of grub development.
Cattle treated with IVOMEC Pour-On at the end of the fly season may be re-treated with IVOMEC during the winter without danger of grub-related reactions. For further information and advice on a planned parasite control program, consult your veterinarian[/quote]
I've never known that, my vet just says that if they have worms pretty bad, then they need to be dewormed instead of letting it go.
