Determining sexual maturity of female macaques requires daily manipulation of animals to obtain a vaginal swab. Typically, animals are pair-housed in cages equipped with squeeze-backs to facilitate positioning of the animals for this process. The behavior team at our facility offered portable transport chutes with dividers as an convenient means of swabbing group-housed, adult female macaques to assist the veterinary team without social group disruption. Use of the transport chutes in this way required modifications to the transport chutes and to the process, involving a collaborative effort between behaviorial, facility and veterinary personnel. Modifications to the equipment and process included designing a frame to match the openings of the transport chute to the social housing unit, a cable hoist to open and close the chute door from inside the pen, a ratchet strap to secure the transport chute to the housing unit, desensitization of animals to the process, facilitation of moving the animal’s tails away from the divider slots inside the chute, modifying materials used for vaginal swabbing, and the introduction of rods to secure the dividers closed while working animals in the chute. Through communication and these modifications and refinements, our behavior team was able to confirm sexual maturity in group-housed females without disrupting social relationships.
