Sex preselection of stallion spermatozoa. This study will develop novel techniques that will maintain and optimise the fertility of sex-sorted stallion semen before and after processing through a flow cytometer. Ultimately, spermatozoa obtained from ejaculation or from the testes sperm storage site (epididymes) at the time of castration will be sorted into X- (female) or Y- (male) populations and used to inseminate mares and thus, enable horse breeders to predetermine the sex of their foal at th ....Sex preselection of stallion spermatozoa.

The introduction of sex-sorted semen into the Australian horse industry (worth some $6.2 billion) will ensure that Australia leads the world in equine reproductive technology.Read moreRead less
Marker assisted selection of honey bees. The project will develop new molecular markers for commercially relevant trait of honey bees and ways of using these to implement marker-assisted selection for honey bee genetic improvement. Beekeepers need to use genetically improved stock to remain competitive. Honey production needs to be improved, and new ways of identifying disease resistant bees are needed. Unfortunately, breeding bees is very difficult. This project will use modern molecular gen ....Marker assisted selection of honey bees. The project will develop new molecular markers for commercially relevant trait of honey bees and ways of using these to implement marker-assisted selection for honey bee genetic improvement. Beekeepers need to use genetically improved stock to remain competitive. Honey production needs to be improved, and new ways of identifying disease resistant bees are needed. Unfortunately, breeding bees is very difficult. This project will use modern molecular genetic techniques to help find new efficient ways to breed better bees. The benefits will be a more viable beekeeping sector, a keystone industry that provides pollination services essential to many horticultural industriesRead moreRead less
