Hi,
I use a Disinfectant that I buy from my local Farmers co-op.
I will find the name tomorrow as it was approved buy the Department of Agriculture when the last out break of Foot and Mouth was on.
When I move any pig or animal for that matter I power wash the inside and out of my trailer and wash the vehicle as well.
Then I spray all the inside of the trailer and the the outside, Making sure to pay particular attention to the wheels of both the car and trailer.
I know this seems like over kill BUT it is not what you take with you to the likes of an abattoir its what you bring home!!!.
When you visit a sale, abattoir or even a show you can not guarantee that every animal is in perfect health, I was once talking to an old hand at a agricultural show and he said to me that Most Pig herds have some health issues it is just that the pigs in that herd have built up an immunity to the particular problems in that herd.
But when you introduce new health issues to your herd that is when the trouble starts.
Remember to disinfect especially after visiting the abattoir as there will have being pigs brought from loads of herds, Mostly commercial and this is where the major problems could be brought HOME!.
I will post the name of My Disinfectant tomorrow.
I do hope this helps.
Kindest regards
Joe
