Lads, what are ye dosing animals with this year? It's like a minefield out there with the amount of different medicines available and I'm sure that a lot of people are making mistakes. A relative dosed all of his recently housed animals with Ridafluke last week and was content that they wouldn't need to be done again until they got back to grass. he was surprised when I showed him the data sheet which showed that Ridafluke only kills mature fluke. He was sold this in a co-op and they told him that ti would kill all fluke! As far as I can see, there is no single dose/pour on/injection that will kill all types of fluke and all types of worm. Some will only kill mature fluke and all types of worm, or all types of fluke and only 1 type of worm. My plan is to go in with 2 separate doses and kill fluke and worms separately. Will probably go with Tribex and then possibly Zerofen or something along that line. The cows will all get levafas diamond after 8 weeks of housing - we normally use it on them evey second or third year. We haven't used pour on for a few years now as we did not see the results. We don't use pour on for lice either - just clip them.
