All animal procedures described here must be conducted in accordance with institutional animal ethics guidelines and approved by IACUC. All procedures must follow the principles of the 3Rs—Replacement, Reduction, and Refinement—and must be performed by trained personnel. Acclimation and Positive Reinforcement Training Pigs are social animals that respond best to calm, low-stress handling techniques. Acclimation and positive reinforcement training are important refinement strategies recommended...

Whether solid, liquid, or gas, a substance's state depends on the order and arrangement of its particles (atoms, molecules, or ions). Particles in the solid pack closely together, generally in a pattern. The particles vibrate about their fixed positions but do not move or squeeze past their neighbors. In liquids, although the particles are closely spaced, they are randomly arranged. The position of the particles are not fixed—that is, they are free to move past their neighbors to occupy...

All procedures must follow the principles of the 3Rs—Replacement, Reduction, and Refinement—and must be performed by trained personnel. Blood collection is a common procedure in swine research and clinical studies. The choice of sampling site depends on the animal's age, body size, the volume of blood required, the study objectives and approved IACUC...
FAQs
Stress responses can arise when pigs encounter altered food access, unfamiliar surroundings, or new social partners. These conditions change the animal’s immediate behavioral and physiological demands, potentially producing exploratory activity, vocalization, aggression, or reduced feeding. Examining several responses together helps researchers distinguish ordinary adjustment from patterns that may indicate difficulty adapting to the new situation.
Introducing pigs to unfamiliar social groups changes their interaction environment and may produce increased aggression or vocalization. At the same time, pigs may explore the unfamiliar setting and adjust how they access food. Monitoring social interactions alongside activity and feeding patterns provides a broader picture of how group changes influence adaptation and welfare during transition.
Changes in feeding provide an important behavioral and physiological indication of adaptation. Altered access to food during events such as weaning or movement between environments may be accompanied by changes in feeding patterns and growth. Researchers interpret these measures with activity, social behavior, and welfare indicators rather than treating feeding behavior as an isolated measure of transition success.
Useful observations include activity patterns, social interactions, vocalization, aggression, feeding changes, growth, and broader welfare indicators. No single response captures every aspect of adjustment. Combining behavioral and physiological information allows researchers to evaluate how pigs respond to a transition and whether housing, group conditions, or handling practices support effective adaptation.
Researchers follow pigs across events such as weaning, transport, mixing, or movement between housing environments, recording changes in activity, social interactions, feeding, growth, and welfare indicators. Comparing these observations across the transition helps reveal immediate responses and adaptation patterns. The resulting information can guide assessments of whether management conditions are supporting acceptable adjustment.
Transition behavior is especially relevant when pigs experience weaning, transport, social mixing, or a change in housing. These events combine altered access to food, unfamiliar surroundings, and new interactions, making them important points for welfare assessment. Behavioral observations can help evaluate whether management practices reduce adjustment difficulties and support better outcomes.
Findings from transition studies can inform housing design, group management, handling practices, and welfare programs. Researchers use observed patterns in activity, social interactions, feeding, growth, and welfare indicators to identify how pigs respond to particular conditions. This evidence supports management decisions aimed at improving adaptation in commercial production and animal behavior research.
