We need to chase down references to their origin. B**tards.
E.g., I start withhttps://www.nature.com/articles/s41598-017-17127-1
Towards the beginning of the Holocene, B. taurus and B. indicus were independently domesticated in the Fertile Crescent (~10,500 yBP) and in the Indus Valley (~8,500 yBP), respectively
One of the citations is

I go to that.https://www.researchgate.net/profile/Mi ... cation.pdf
Molecular markers were used to investigate the intriguing origins of these cattle. Taurine cattle from Europe and Africa and zebu cattle from India and Africa were compared at the molecular level. Surprisingly, Indian zebu cattle were found to have profoundly different whole mtDNA RESTRICTION FRAGMENT LENGTH POLYMORPHISM (RFLP) profiles39 and control-region sequences, when compared with both European and African taurine cattle and African zebu cattle — which all shared similar sequences. The level of sequence divergence between the two mtDNA lineages was consistent with a most recent common ancestor dating to hundreds of thousands of years BP. However, cattle domestication was known to have occurred much later than this, within the last 10,000 years . So, the most probable explanation for this high level of molecular divergence
was that genetically differentiated subspecies of the ancestral wild cattle Bos primigenius (also known as aurochs) had been domesticated in different regions of Eurasia.
I chased down reference  above (I've removed other references in the quote above).
Perkins, D., Jr. Fauna of Çatal Hüyük: evidence for early cattle domestication in Anatolia. Science 164, 177–178 (1969).http://science.sciencemag.org/content/164/3876/177
Analysis of the remains of cattle from Çatal Hüyük indicates that cattle were domesticated in Anatolia by 5800 B.C., and strongly suggests that they were probably domestic at least 500 years earlier. This is the earliest known evidence for the domestication of cattle in the Near East.
So if cattle were domestic around 6300 BC in Anatolia; i.e., 8300 ybp - notice how that became ~10,500 ybp in the first citation.
Earliest Mehrgarh dates to is ~6500 BC. When are domesticated cattle found there?
For Mehrgarh, need to find this report:

Haven't found it yet, but found this in the meantime:
