We need a rise in temperatures
The grass-seed sown on June 10 is now only starting to grow. What we need now is a rise in temperatures as we have got enough of the rain.
These fields will not be fit to graze at weaning time, so the lambs will be put onto fields that have been grazed out well by the ewes and now have a good cover of leafy grass.
The most important thing for the lambs is to have a good worm-control programme in place. It's vital to know that the dose you are using is working and that you don't have a worm-resistance problem.
The way to find out is to take individual dung samples from 20 lambs in a group. Dose the lambs, then have the dung samples counted for worm eggs -- this can be done at your local veterinary laboratory. After 10 days repeat dung samples from the same 20 lambs and compare the readings.
If the worm count is not reduced or has increased, then the product you are using is not working. So you must move onto another product.
On our farm, four years ago, this dung sampling approach showed us we were 60pc resistant to the 'white drenches' and 25pc to the Levamisole.
So now we use a Levamisole-type drench first to cover nematodirus and then go in with an ivermectin-type dose (Cydectin) when the lambs are about 10 weeks old.
