A training program has been in place at Disney's Animal Kingdom since the nonhuman animals first arrived at the park. The Primate Team and the Behavioral Husbandry Team have worked together closely to establish a philosophy and framework for this program. This framework emphasizes setting goals, planning, implementing, documenting, and evaluating. The philosophy focuses on safety, staff training, and an integrated approach to training as an animal management tool. Behaviors to be trained include husbandry and veterinary as well as behaviors identified for specific species, individuals, or situations. Input from all the teams was used to prioritize these behaviors. Despite the challenges to maintaining such a program, the benefits to animal care and welfare have been enormous.

Fenclorac (a,m-dichloro-p-cyclohexlphenylacetic acid, diethylammonium salt) is a potent nonsteroidal anti-inflammatory agent with significant analgesic and antipyretic activity. Fenclorac had an ED50 of 7.9 mg/kg in the carrageenan paw edema assay and had a duration of action of 18-22 hours. Comparative tests in the carrageenan paw edema assay in the rat indicated that the potency of fenclorac was 13 times that of aspirin, 3.4 times phenylbutazone, 3 times ibuprofen and 0.3 times indomethacin. Fenclorac was less potent than indomethacin, but more potent than phenylbutazone or aspirin in treatment of developing or established adjuvant arthritis. The anti-inflammatory effectiveness of fenclorac did not depend upon the integrity of the adrenopituitary axis and was not affected by the route of administration or sex of the test animal. Fenclorac was 77 times more potent than aspirin and more than twice as potent as indomethacin in reducing fever in rats rendered hyperthermic with brewer's yeast. Fenclorac did not affect normal body temperatures. Fenclorac did not interfere with cellular immune mechanisms as measured by its lack of effectiveness in experimental allergic encephalomyelitis. Antinociceptive testing indicated that fenclorac had peripheral but not central analgesic activity. Fenclorac had an acute oral LD50 in rats and mice of 285 and 430 mg/kg, respectively. The acute gastric lesion UD50 for fenclorac was 7 mg/kg in the fasted rat. Studies using 51Cr-tagged erythrocytes indicated that fenclorac did not produce significant fecal blood loss in the rat at twice the therapeutic ED50 dose for up to 12 days after dosing. Extensive and prolonged fecal blood loss was observed with a corresponding dose of indomethacin for up to nine days after administration. Comparison of the anti-inflammatory pharmacology, Therapeutic Ratio and the data obtained from the 51Cr-fecal blood loss studies indicated that fenclorac was well tolerated after acute or subacute administration to the rat.
