Reproduction of genome-tested sex-determined cattle using egg aspiration and in vitro fertilization Project leader Ilga Šematoviča Duration 2024 - 2028 Research focus 2. Preservation of biological diversity in agro- and forest biocenoses, ecosystem protection and services Source of funding National grant Project partners LBTUSidnija PodnieceSIA NaukšēniZS Grasbergs VeterinārijaBiedrība LHAVVSIK Konsultācijas Description of project The aim of research The project aims to target genome-tested, sex-determined cattle breeding using a newly developed assisted reproduction method in Latvia - egg aspiration and fertilisation in the laboratory with subsequent transfer of fresh and/or frozen embryos. The idea is based on intensive breeding of animals that, through genome testing, have been determined to have lower GHG emissions, higher feed utilisation efficiency, productivity, better milk quality in terms of milk fat and protein, lower somatic cell count in milk, better reproductive performance, longevity, as well as other criteria essential for dairy farming in terms of environmental friendliness and economic efficiency. An additional benefit will be the non-breeding of genetically inferior animals, thus reducing the herd's GHG emissions and saving fuel, natural resources and human resources. The tasks of project: Genomic Testing, OPU/IVF, CO2 and NH4 monitoring at the beginning and end Results In progress
