Mother sheep with lambs
These lambs were born as part of a maternal nutrition study. Whenever possible, lambs needed for research studies are raised with their mothers for normal social and emotional development. If the study requires hand-rearing, it must be approved by the Institutional Animal Care and Use Committee (IACUC), a committee responsible for ensuring that all work with animals is humane and in compliance with laws, policies and guidelines. In these cases, they are housed with other lambs for social stimulation and given additional enrichment and interaction with their caregivers.
