Zebrafish larvae are raised from eggs to eventually become breeding adult fish that provide embryos for research studies. The transparent bodies of these young fish allow for non-invasive assessment of organ and tissue changes, something that is not possible with mammals. Their transparency is very helpful when conducting…

Male and female Rock Doves (pigeons) in this research facility raise their babies together in a large, open, indoor aviary. The aviary includes perches, swings, water baths, nest bowls, and foraging opportunities to stimulate the birds' natural behaviors. Parents will hatch one to three squabs (baby pigeons) on…
Rabbits in this research facility are socially housed in runs with paper bedding, tunnels, dividers, toys, and treats, providing them with opportunities to hop, dig, play and forage for treats. The rabbits are identified with non-toxic ear markers that allow caregivers and researchers to track them and their…
Minipigs needed for research are fed on the floor so that they can root and forage for their feed using their snout. They are also offered many different types of toys to help provide tactile enrichment as they enjoy sniffing, touching and manipulating objects with their snouts. And,…
