In vitro prediction tests of fertility of frozen semen of sheep and cattle. Variation in fertility after artificial insemination (AI) of frozen semen is high and leads to economic loss. Routine assessment of the quality of frozen semen relies on crude, simple tests of motility and morphology of sperm. More sophisticated sperm ultrastructural and function tests have recently been developed, but it is not known how these tests relate to fertility in the field. In this project we will test a ran ....In vitro prediction tests of fertility of frozen semen of sheep and cattle. Variation in fertility after artificial insemination (AI) of frozen semen is high and leads to economic loss. Routine assessment of the quality of frozen semen relies on crude, simple tests of motility and morphology of sperm. More sophisticated sperm ultrastructural and function tests have recently been developed, but it is not known how these tests relate to fertility in the field. In this project we will test a range of in vitro methods of assessment of motility and morphology of sperm and compare them with fertility of frozen semen samples after AI, leading to more objective methods of semen analysis.Read moreRead less
Development of a proto-type vaccine against gastrointestinal nematode larvae. Gastrointestinal parasites are the major cause of production losses in the Australian sheep and wool industries. Drug treatment is predominantly used to control infections but drug resistance has reached critical levels and is threatening the viability of sheep production in many rural areas. In collaboration with an international Animal Health company, we aim to develop vaccines against these parasites and provide a c ....Development of a proto-type vaccine against gastrointestinal nematode larvae. Gastrointestinal parasites are the major cause of production losses in the Australian sheep and wool industries. Drug treatment is predominantly used to control infections but drug resistance has reached critical levels and is threatening the viability of sheep production in many rural areas. In collaboration with an international Animal Health company, we aim to develop vaccines against these parasites and provide a clean, non-toxic alternative to drug treatment. The groundbreaking research involved in this project will also keep Australian animal scientists at the forefront of vaccine research and increase their capacity to attract further support from Industry.Read moreRead less
Topical and cryoanaesthesia for livestock husbandry. The livestock industries contribute $15billion annually to Australia's economy, playing a vital role in rural communities. However we must respond to changing demands of our customers, by complementing our competitive disease-free advantage with welfare-conscious production systems. This project will address the threat of growing international demands for improved animal welfare in farming. We will provide research and technical solutions, pro ....Topical and cryoanaesthesia for livestock husbandry. The livestock industries contribute $15billion annually to Australia's economy, playing a vital role in rural communities. However we must respond to changing demands of our customers, by complementing our competitive disease-free advantage with welfare-conscious production systems. This project will address the threat of growing international demands for improved animal welfare in farming. We will provide research and technical solutions, providing pain mangement products for on-farm use that will reduce animal suffering during routine husbandry interventions. The project offers significant benefits for producers by protecting their industries against the threats of a welfare embargo on our livestock products. Read moreRead less
