Such approaches require relatively large investments, particularly if multiple individuals from multiple breeds have to be screened.
Since the bovine genome and HapMap projects have been completed17,18,19, the whole-genome resequencing of multiple cattle breeds has progressed rapidly, including B. taurus (Hereford, Angus, Hanwoo, Yanbian, and Japanese native cattle), B. indicus (Gir, Nellore), dairy cattle (Holstein, Fleckvieh) and yak20,21,22,23,24,25,26,27.
More recently, whole-genome sequencing of multiple chicken breeds has led to the identification of thousands of single nucleotide polymorphisms (SNPs), providing very high-density genetic maps compared to the previously low-density microsatellite marker maps [ 7].
Previous reports across multiple dairy breeds have similarly found that the NZ population is genetically different from other dairy cattle populations [ 18- 21].
Most studies on genomic prediction with reference populations that include multiple lines or breeds have used linear models.
These data suggest that previously identified sub-groups within the widespread modern cattle mitochondrial T clade are polyphyletic, and they support the hypothesis that modern European breeds have multiple geographic origins.
The French breeds have much Swiss blood.
Both breeds had fluctuating CH4 throughout the days of sampling.
The four breeds had statistically identical ear temperature, but the rectal temperature of the rabbits was influenced by breed.
