The weather has been dry, unrelentingly hot (by our modest standards) and very windy. Consequently, it has gone from good spring/early summer to very tight late summer. Notwithstanding, sheep are in good order and lambs growing well on dedicated crops.

Not surprisingly, the worms are quiet. So, all that needs be said is that those in the north of the State (say, north of Ross) should be preparing for a second summer drench for all sheep on perennial pastures. Those in the southern midlands should get away with one drench. The Derwent Valley is a bit of a mixed bag as some parts received a bucket of rain in early December, which may have extended the season.

It’s timely to remind readers of their ram flock: you know, that often-neglected mob that run out of sight and mind for most of the year. Rams are now very expensive, and ram failure is even more so. So, in preparation for joining check them now: teeth; tossle; toes and testicles. Chances are they missed a summer drench so give them one, and another on the point of joining. And some high protein supplementation to improve testicular tone (protein, not grain).

Finally, a problem to consider: a client wanted a worm-free farm. He had recently bought two new blocks, both of which had not run sheep for some years. Could he make introduced sheep worm free, and reap the benefit indefinitely? Well, we could give them a 4 or 5 way combination and hope we got every worm. Experience (for example, people restocking after Johnes quarantine) suggests that there is a tiny residual population, which, not surprisingly, is super resistant. He had figured this out and decided to stock the place with sheep from his home place which had fair to good resistance status. He asked my advice retrospectively, and I think he has done the right thing.
