Worm Control In Sheep In Western Australia. Crack Down On Worms: An Information Guide For Advisers, Consultants, Livestock Personnel And Farmers, Department Of Agriculture, Western Australia

Animal production and livestock published reports

In Western Australia’s winter rainfall areas, the control of gastro-intestinal sheep worms is based on the strategic timing of drenches.

Sheep are drenched at a time that reduces the contamination of pastures with worm eggs and larvae in late summer and autumn. The timing of the drenches is particularly important for the control ofbrown stomach worms (Ostertagia species) and black scour worms (Trichostrongylus species)

Drenches given in late spring, when pasture is starting to dry off, and again in summer, successfully reduce pasture contamination in mid summer and autumn. A faecal egg count will determine the need and timing of …

Paddock Sampling For Management Of Annual Ryegrass Toxicity, Ian Riley

Journal of the Department of Agriculture, Western Australia, Series 4

Annual ryegrass (Lolium rigidumJ seedheads containing corynetoxins, a group of bacterially produced antibiotics, are poisonous to livestock. Animals that eat affected ryegrass develop annual ryegrass toxicity (ARGT), suffer convulsive staggers and die within a few days of eating a lethal dose. ARGT is characterised by high death rates, especially where pastures are not known to be affected and where stock-owners are not expecting the problem. Fortunately, there are commercial tests that determine the levels of ARGT organisms in the paddock and the risk of getting the disease. These tests will help farmers plan their cropping and pasture programs for the …
