A study just published in the august journal the Veterinary Record looked at levels of parasites in cattle in organic farms as opposed to a similar group of ‘ordinary’ farms. This comes against a background of the rising level of liver fluke infestation that is causing some concern.
The non-organic farms routinely used anthelminthics – parasite-killing drugs – as part of their management regime for all their animals, whether they appeared affected by parasites or not.
Organic farms are not allowed to use such medication unless an animal is actually ill with parasites. Instead they have to rely on more traditional methods such as grazing their cattle on reseeded pasture, moving their stock regularly onto new clean pasture, grazing calves with sheep or a combination of all three.
The result?
Both groups had similarly low levels of parasites, indicating that control strategies on both groups were effective.
Where many had suspected that the wholesome animal-welfare-friendly image of organic farming might in fact be hiding more serious health issues for cattle, for this study at least, their fears appear groundless.
Organic really is good for us and the animals on these farms.
It gets slightly worse for the animals on all systems of course when, despite our concerns about their welfare, we kill them and eat them.
