Queensland worms, flies and lice update - November 2015

Texas: Noel O’Dempsey, Sheep Veterinary Consultant (odempseyn@gmail.com)

We received good rain in the district over the weekend (60 odd mm over three days in three storms).

Some people have received enough rain now to at least start thinking about restocking. Where are the sheep going to come from? NSW and points south is the obvious answer.

With this comes at least three issues that you will have to consider apart from paying for them:

Drench resistance— you do not want to buy drench resistance in the worms that come with the sheep you purchase. A good quarantine plan (including effective drenching) is required and should be in place before the sheep arrive. WormBoss has all you need to know.

Ovine Johnes Disease—be sure before you check that the sheep are eligible for entry into Queensland.

Sheep lice—most sheep purchased are a couple of months off-shears at inspection. Sheep lice are very difficult to find at this stage. Plan for purchased sheep to be lousy and be happy when they are not. A National Sheep Health Statement is a good starting point.

 

Longreach: Charlie Nolan, Program Manager Agribusiness, Longreach Pastoral College (charles.nolan@qatc.edu.au)

Across the Longreach area, there have been isolated showers of up to 200 mm reported across narrow strips of the semi-arid regions of Queensland. Some graziers downstream have running creeks and rivers across their parched rangelands after having recorded a nil rainfall over the past 6 months.

In the same period, Longreach Pastoral College reported 24 mm over the campus and less than 5 mm across its aggregate. The bush flies are herding the remaining sheep and cattle, which are now on a full hand feed program.

Our spring internal/external parasite control program has been actioned. Parasite control programs are a primary consideration for Longreach Pastoral College because the sheep and cattle are held in confined areas on a full supplementary feed program.

Across the region there are areas where storms did produce reasonable falls to stimulate pasture growth. Following such storms, sheep and cattle tend to graze in tight mobs on their preferred areas of emerging green, new pasture growth. Graziers should closely monitor their sheep and cattle for internal and external parasite levels and ensure that the appropriate control measures are in place to maximise production and mitigate any loss.
