Genetic improvement is imperative to increase the efficiency of milk and meat production indeveloping countries, improving the availability of healthy nutritious food, maximising feed efficiencyand minimising environmental impacts. Utilising genomic selection, ovum pick-up (OPU) and in-vitroembryo production (IVP) routine selection and breeding is accelerated - no genes are modified. Sohighly desirable UK genetic traits can be sent to Zimbabwe cost effectively, minimising biosecurity risks,and allowing calves to adapt to the environment from birth. This breeding plan will then multiply thesegenetics locally utilising multiple ovulation embryo transfer (MOET), developing a genomic index toreselect, reamplify and rapidly accelerate genetic gain. There are 3 key objectives: 1. To investigate thelikely performance of implanting selected bovine embryos produced by OPU/IVP in the UK intoindigenous cattle in Zimbabwe; 2. To develop and optimise an embryo production and transferplatform in Zimbabwe to amplify the imported genetics into more herds; and 3. To develop a newveterinary-led animal health service, facilitating the establishment of a practice supporting local dairyfarmers with high quality veterinary care and health management including reproductive technologies.

基因改良对于提高发展中国家的牛奶和肉类生产效率、改善健康营养食品的可获得性、最大限度地提高饲料效率和最大限度地减少对环境的影响至关重要。利用基因组选择、取卵(OPU)和体外胚胎生产(IVP)常规选择和繁殖被加速--没有基因被修改。因此，非常理想的英国基因特征可以经济有效地送到津巴布韦，将生物安全风险降至最低，并允许牛犊从出生起就适应环境。这一育种计划将利用多个排卵胚胎移植(MOET)在当地繁殖这些遗传基因，开发一个基因组指数来重新选择、重新扩增和快速加速遗传增益。有三个主要目标：1.调查由英国OPU/IVP生产的精选牛胚胎移植到津巴布韦本地牛身上的最佳表现；2.开发和优化津巴布韦的胚胎生产和移植平台，将进口的基因放大到更多的牛群中；3.发展以兽医为主导的新的动物保健服务，促进建立支持当地奶农提供高质量兽医护理和包括生殖技术在内的健康管理的做法。
