There are few hard statistics on either side of the issue. Many charreadas are loosely organized in the USA and obtaining data is a challenge. Informal reports by organizations on both sides of the issue exist. The American Horse Defense Fund claims that from 8 to 20 percent of horses leased for charreada in California were reported to be injured seriously enough to be "sent to slaughter" each week, and the president of the California Equine Council claimed to personally observe a circuit of 10 charreadas for which 78 horses were leased for a season's use, and only 2 were not sent to slaughter by the season's end. Arabian horses are said preferred by charros due to their lighter weight, and Arabian horse rescue organizations have reported on encountering rope-scarred animals in slaughter yards whose injuries have been attributed to charreada use by the feedlot owners.
