Excitatory neuropeptides from nematode parasites of sheep. Internal parasites cause major disease and economic loss in Australian agricultural industries. Control, usually achieved with drugs, is now compromised by drug resistance and new remedies are required. Results of recent DNA sequencing projects have allowed us to predict the presence of neuropeptides in the worms of sheep. The aim of this project is to elucidate the steps in the action of these peptides, in particular, those that cause m ....Excitatory neuropeptides from nematode parasites of sheep. Internal parasites cause major disease and economic loss in Australian agricultural industries. Control, usually achieved with drugs, is now compromised by drug resistance and new remedies are required. Results of recent DNA sequencing projects have allowed us to predict the presence of neuropeptides in the worms of sheep. The aim of this project is to elucidate the steps in the action of these peptides, in particular, those that cause muscle contraction. By understanding the action of these peptides we hope to identify targets against which new drugs for parasite control can be developed.Read moreRead less
Development of a topical treatment to replace surgical mulesing in sheep. 10,800 farms in Australia are sheep farms and a further 30,000 have sheep. Exports of wool earn over $2 billion annually. The animal rights campaign to ban mulesing has forced the industry to outlaw mulesing by 2010. Mulesing is largely confined to Australian Merino sheep and requires Australian research. If practical alternatives are not found costs will rise compromising the economic viability of many sheep farms. C ....Development of a topical treatment to replace surgical mulesing in sheep. 10,800 farms in Australia are sheep farms and a further 30,000 have sheep. Exports of wool earn over $2 billion annually. The animal rights campaign to ban mulesing has forced the industry to outlaw mulesing by 2010. Mulesing is largely confined to Australian Merino sheep and requires Australian research. If practical alternatives are not found costs will rise compromising the economic viability of many sheep farms. Chemical use on the breech will increase causing environmental contamination. A simple topical alternative to mulesing will allow farmers to economically manage flies and satisfy welfare imperatives. This will support rural communities and sustain Australia's export income from wool.Read moreRead less
Improving the wool product. Using mathematical modelling to improve the efficiency of wool scouring. Our aim is to improve the quality of scoured wool by improving the efficiency of wool scouring. Wool scouring is the process of washing greasy wool once it has been removed from the sheep's back. After being rinsed to remove sweat and salt the wool is passed through a scour bowl consisting of settling tanks from which dirty water is periodically expelled. Mathematical modelling will optimise us ....Improving the wool product. Using mathematical modelling to improve the efficiency of wool scouring. Our aim is to improve the quality of scoured wool by improving the efficiency of wool scouring. Wool scouring is the process of washing greasy wool once it has been removed from the sheep's back. After being rinsed to remove sweat and salt the wool is passed through a scour bowl consisting of settling tanks from which dirty water is periodically expelled. Mathematical modelling will optimise use of the scour bowl, reduce consumption of water, increase the recovery of wool grease and improve the quality and cleanliness of the wool.Read moreRead less
