* No Central Database: There's no global organization that tracks the exact number of Holstein cows in every country.
* Constant Fluctuations: The number of Holstein cows changes constantly due to factors like births, deaths, culling, and sales.
* Differences in Definitions: Some counts might include all Holstein cows (dairy and beef), while others focus only on dairy cows.
However, we can provide some general information:
* Prevalence: Holstein cows are the most popular dairy breed worldwide, accounting for a significant majority of dairy herds.
* Estimated Numbers: Some estimates suggest that there are tens of millions of Holstein cows globally.
* Regional Variations: The number of Holstein cows varies greatly from country to country, with higher concentrations in major dairy-producing regions.
If you need a more specific number, you might be able to find data for individual countries or regions from agricultural organizations or government agencies.
