Once every ten years, the National Animal Health Monitoring System (NAHMS) of the U.S. Department of Agriculture conducts a survey of Beef Cow-Calf Management Practices. The most recent survey was conducted in 2007-2008 and the results were published in 2009.
I am attaching a PDF copy of Part II of the 2009 report, which includes several pages addressing the use of reproductive technologies. None of the tables provide a state-by-state parsing of the statistics; the closest are percentages found in a regional table on page 20: data for Nebraska are included in the "Central" region and data for Texas are included in the "South Central" region. (See the appendices at the end of the document for information about how the survey was conducted and the geographies parsed.)
You may find it useful to examine other parts of the report at the NAHMS website:

I am also attaching a PDF copy of an article published in the Journal of Animal Science in 2011, "Multi-State Beef Reproduction Task Force Provides Science-Based Recommendations for the Application of Reproductive Technologies." This article gave me the lead to the NAHMS survey, and it is the most recent summary of reproductive interventions that I can find.
