To get the most accurate and up-to-date information on the number of cattle in Oklahoma, I recommend checking these resources:
* Oklahoma Department of Agriculture, Food, and Forestry: They often publish reports and statistics on agricultural production, including livestock.
* United States Department of Agriculture (USDA): The USDA National Agricultural Statistics Service (NASS) collects and publishes data on agriculture, including livestock inventories. You can find reports and data on their website.
* Oklahoma Farm Bureau: This organization often has information on agricultural trends in Oklahoma.
Please note that these numbers can change frequently, so always try to get the latest information available.
