State Outlooks for June 2021

June has seen cool and wet conditions across the country as we move well into the winter months. Don't forget, this is the time when worms present an ongoing risk to your flock, or an increased risk if you are in an area which receives a lot of rainfall during winter, so make sure you continue to monitor this closely.

Lambing season is now well underway, so it's a key time to watch for a periparturient rise in worm numbers. As always, continue to monitor worms using worm egg counts (WECs).

If you haven't already, it is advisable that you conduct a Drench Resistance Test (DRT) for 2021. Information on this can be found on the ParaBoss website or contact your local veterinarian.

New South Wales

Seasonal changes across the region mean you can’t just rely on an annual routine for drenching. A tailored approach is required depending on a number of factors. Interestingly, the large number of twins scanned around the district, the delayed appearance of winter medics and fodder crops, and the late shearing that many producers have been forced into means that extra attention needs to be paid to your lambing ewes and young stock over the coming months.

Advice locally is to continue to monitor weaners every three to four weeks, and WEC sheep prior to marking to determine whether or not drenching is required. Ensure WEC results are recorded against paddocks as well as mobs to monitor for paddock contamination as we eventually come back towards the spring months.

With lambing imminent on many properties, concerns are for the ewes and any early drop lambs. Pastures should be low-worm so that lambs are not setback by an infection early in life. While the mid-length (some combined with vaccine) and long-acting mectin/ML (macrocyclic lactone) products provide convenience, they are better off reserved for the higher risk times of autumn and summer.

Lamb marking is an important time to monitor worm burdens in ewes. At lambing, an ewe’s natural immunity to worms drops and worm numbers can increase. There’s no change to the advice over the last couple of months: WECs need to be very low ahead of the lambing date, and a check about three weeks out gives time for a drench if needed.

The region has seen a few disasters wherein mobs of merinos have crashed over about a week. Beware, worms are about. Older sheep, particularly XB ewes are generally good with carryover body condition keeping the worms at bay. It’s time for the annual decision on what to use pre-lambing. This is easy for the XB flocks: nothing or whatever short-acting drench that works.  


South Australia

Season opening rainfall finally prevailed by mid-June for most agricultural areas in South Australia, enabling seeding to proceed and dry sown seed to germinate. An ideal pasture for weaning is one that has sufficient good quality feed (at least 1200kg dry matter per hectare or a dense green pasture with an average pasture height of 4cm) to support weaner growth as well as a low worm risk i.e. has not been grazed for four to six months.
