Since 2010, genomic evaluations procedures started as a new technology to replace the traditional genetic evaluation systems for breeding purpose to improve dairy cattle industry. Genomic evaluations utilize the genomic marker information in addition to both phenotype and pedigree information. Dairy cattle evaluation performed in two levels: national and (inter)national levels. The evaluation at national level helps to make choices of which domestic bull to use for artificial insemination within the national breeding program. The evaluation at international level helps to make accurate choices of which foreign bull or semen to import from different countries, which is essential for improving dairy cattle industry globally. Two approaches are suggested for international genomic evaluations: single-trait approach (ST) and multi-trait approach (MT). Based on a real data, the current thesis has been carried out at Interbull center (International Bull Evaluation Service, interbull.org) to explore the benefits from using a multi-trait approach of genomic evaluations as an alternative to the single-trait approach.

I am a veterinarian interested in animal genomics. I want to work with livestock improvement, in national and international level, by using efficient statistical methods to process phenotype, genotype, pedigree, and DNA sequence data.
