Maternal and paternal genealogy of Eurasian taurine cattle (Bos taurus)
Heredity (2009) 103, 404–415; doi:10.1038/hdy.2009.68
Has this very interesting (ok, to me, anyway) figure that I don't really understand, but there are codes for various breeds and genetic differences across geographies seem to be characterized by color changes.
Trying to figure out the dark blue area of REG, Red Gorbatov cattle in the USSR, took me to this publication about Animal Genetic Resources of the USSR.
http://www.fao.org/docrep/009/ah759e/ah759e08.htm
My favorite is the Yakut, last on the page.
"When properly fed and managed Yakut cows are noted for their long productive life: among the cows studied by Romanov in 1963 the 12-year-olds accounted for 25.9%. The better cows in the conservation herd have a milk yield of 2100-2350 kg with 6.1-7.3% fat."
They even have their own haplogroup, whatever that is.
From the abstract, concerning the Yakut
... Here, we provide mtDNA information on previously uncharacterised Eurasian breeds and present the most comprehensive Y-chromosomal microsatellite data on domestic cattle to date. The mitochondrial haplogroup T3 was the most frequent, whereas T4 was detected only in the Yakutian cattle from Siberia.
