Cows Escape During Houston Rodeo Setup (VIDEO)

Two cows briefly roamed the streets of Houston, Texas, after they escaped a rodeo setup on Feb. 27.

Daisy and Lucy were startled by loud noises when handlers were unloading them prior to the event, KTRK reports. That's when the animals took off.

Although Lucy was captured within moments of her escape, Daisy decided to give workers preparing for the show a bit of a work out, according to video footage from CBS.

While on the loose, the cow charged at anyone who approached her, even head-butting and stepping on one worker. Fortunately, the man did not sustain any serious injuries.

Both Daisy and Lucy are newcomers to the Houston Livestock Show and Rodeo, which runs through March 18, but we think it's safe to say they've already made quite an impression.

Rodeo organizations say they adhere to certain rules and regulations to ensure the well-being of livestock and other animals involved in rodeo events.

The Professional Rodeo Cowboys Association, for example, says it enforces the humane treatment of animals and that any violation of the rules can result in disqualification and fines, according to the group's official website.

In addition, the organization requires veterinarians on site at all events, MSNBC reports.

It is worth noting, however, that due to a disagrement over which events would be included, this year's Houston Livestock Show and Rodeo is not being sanctioned by the Professional Rodeo Cowboys Association.

Nevertheless, a 2006 survey conducted by the PRCA that revealed 38 animals were injured out of the nearly 62,000 times they were used at events across 159 rodeos, MSNC reported. A 2009 survey revealed a 0.00037 percent injury rate among nearly 75,000 animals in 194 performances, the Wyoming Tribune Eagle reports.

Still, an article featured in Mother Jones observes that the PRCA is exempt from the Animal Welfare Act, a law meant to regulate "the treatment of animals in research, exhibition, transport, and by dealers," or "specifications for animal care and use."

In 2010, a horse was euthanized after sustaining a lower lumbar fracture sustained during a fall at the Houston Livestock Show and Rodeo, the Houston Chronicle reports. A veterinarian concluded the animal wouldn't have survived the injury.

Daisy and Lucy's excursion was extremely short-lived when compared to fugitive cow Yvonne's memorable escape last summer.

The 6-year-old cow escaped from a farm in Germany, where she was reportedly being prepared for slaughter. She was on the loose for three months before a farmer found her on his property. Yvonne now lives in an animal sanctuary.
