Officials said the giraffe had a severe cough and overall agitation.

"The Zoo’s veterinary staff took immediate measures to help, including swiftly administering medications to stabilize," the zoo said in a statement. "As well, he underwent constant staff evaluation to optimize his chances of recovery. The Zoo’s team reached out to numerous zoological veterinarians throughout the nation — none of which had experienced a giraffe with comparable symptoms."

An LSU veterinary team performed a necropsy to determine the official cause of death. Results are expected to come within 30 days.
