The event has provoked concerns among some
animal welfare advocates that practices used in the event may constitute
animal cruelty. Modern rodeos in the United States are closely regulated and have responded to accusations of
animal cruelty by instituting a number of rules to guide how rodeo livestock are to be managed. A study of rodeo animals in Australia found a similar injury rate. Basic injuries occurred at a rate of 0.072 percent, or one in 1,405, with injuries requiring veterinary attention at 0.036 percent, or one injury in every 2810 times the animal was used, and transport, yarding and competition were all included in the study. A later PRCA survey of 60,971 animal performances at 198 rodeo performances and 73 sections of "slack" indicated 27 animals were injured, again approximately five-hundredths of 1 percent – 0.0004. However, accusations of cruelty in the USA persist. The PRCA acknowledges that they only sanction about 30 percent of all rodeos, while another 50 percent are sanctioned by other organizations and 20 percent are completely unsanctioned. They cite various specific incidents of injury to support their statements, and also point to examples of long-term breakdown, as well as reporting on injuries and deaths suffered by animals in non-rodeo events staged on the periphery of professional rodeo such as
chuckwagon races and "suicide runs". While in terms of actual statistics on animal injury rate, there appear to be no more recent independent studies on animal injury in rodeo than the 1994 study, groups such as PETA gather anecdotal reports such as one from a 2010 rodeo in Colorado alleging eleven animal injuries, of which two were fatal. There are economic incentives to keep animals healthy enough for continuing rodeo participation. Bucking horses and bulls are costly to replace: a proven bucking horse can be sold for $8000 to $10,000, making "rough stock" an investment worth caring for and keeping in good health for many years. Activists also express concern that many rodeo horses end their lives as
horsemeat. While it is accurate that some rough stock animals are
slaughtered for
horsemeat at the end of their useful careers, other bucking horses are retired at the end of their rodeo usefulness and allowed to live into old age. The issue of
horse slaughter crosses all equestrian disciplines and is not confined solely to the rodeo industry. Any unwanted horse can meet this fate, including
race horses, show horses, or even backyard pasture pets. Over the years, some states imposed regulation upon certain techniques and tools used in rodeos. Under PRCA guidelines, electric prods may not deliver a shock stronger than can be produced from two D batteries. Prods are allowed as long as the situation requires them to protect the people or the animals. and harm to the genitalia is
anatomically impossible because the
stifle joint of the hind leg limits how far back a flank strap can be attached. However, while the implied argument behind this claim is that pain is what makes the horse buck, in actual practice, irritants or pain generally interfere with a horse's ability to buck in an energetic and athletic fashion. ==Cultural significance==
