This project will apply advanced breeding technologies to amplify and distribute bovine genetics to increase production efficiency and sustainability. Strand 1;- Utilisation of "ovum pickup" (OPU) and "in-vitro embryo production" (IVP) to accelerate the speed of genetic gain in cattle (3 times faster than "multiple ovulation embryo transfer" (MOET) and 12 times faster than conventional breeding). There is a need to; improve reliability and consistency of embryo production; improve efficacy of sexed semen in IVF; develop "quick thaw" systems; expand the network of collection and transfer centres; create a route to export for sexed, frozen embryos. Strand 2;- Development of robust techniques to allow rapid, affordable, real-time assessment of bovine fertility interventions; identify criteria within the OPU/IVP system that act as fertility markers.

该项目将应用先进的育种技术来扩增和传播牛的遗传基因，以提高生产效率和可持续性。链1;- 利用“取卵”和“体外胚胎生产”加快牛的遗传获得速度（比“多排卵胚胎移植”快3倍，比传统育种快12倍）。有必要;提高胚胎生产的可靠性和一致性;提高体外受精中性别鉴定精液的效力;开发“快速解冻”系统;扩大收集和转移中心网络;为性别鉴定的冷冻胚胎开辟出口途径。链2;- 开发强大的技术，以快速，负担得起，实时评估牛生育力干预措施;确定OPU/IVP系统中作为生育力标记的标准。
