Fertility of sexed ram semen 18/19

The ability to pre-select the production of male or female lambs will provide a number of benefits to the Australian wool industry. Sex pre-selection can streamline flock management, reduces the costs associated with progeny testing, allows producers to focus selection on a ewe line, and can improve the rate of genetic gain under certain breeding strategies. The positive results achieved by this project with liquid sexed semen have had global impact, providing the final piece of evidence needed by a US artificial breeding company to buy the rights to distribute sexed ram semen from Sexing Technologies. This has resulted in, for the first time, a commercial sexed semen product being launched in the USA and Australia, distributing fresh and frozen sexed ram semen doses for artificial insemination.

Zondii On farm Wool Classing

Using patented scientific technology the project aims to enable producers to scan wool in-shed and detect micron, colour and crimp of the wool, by creating machine learning models accessed by affordable non-connected devices. This project will benefit the producer by providing real time wool test results cheaper and quicker than current laboratory options, allowing more sheep to be tested.

Next generation wool harvesting

This project will explore the potential for developing an alternative to conventional shearing through R&D directed towards a novel approach, based on delivering a product by feed or injection, which creates a weakened zone in the fleece. The fleece can then be removed by unskilled labour or an automated high-throughput system. If successful, this project will revolutionise wool harvesting, by improving wool quality, eliminating shearer injuries, allowing producers to decide harvesting time, harvesting small numbers of sheep and improving sheep welfare.

Laser for permanent removal of wool foll

The purpose of this project is to research and develop for adoption alternative technologies for wool follicle removal (lambs 8-12 weeks old) that could apply to mulesing and crutching as well as animal husbandry for the meat industry on older sheep.
