Stereotaxic surgery on rodents allows for targeted administration of drugs or electrical stimulation and recordings in awake, behaving animals. In this video presentation we will demonstrate recent procedural refinements to this long-standing procedure that successfully improved survival rate and reduced post-surgical weight loss.

Nest Building as an Indicator of Health and Welfare in Laboratory Mice

We demonstrate the utility of nest building behavior in laboratory mice as an indicator of welfare. Nest scoring is a sensitive technique that is altered by temperature, illness, and aggression. The time to integrate into nest test (TINT) is a simple cage-side assessment that can detect postoperative pain.

First Welfare Theorem II

Markets don’t always work perfectly. In theory, they should allocate resources efficiently, but real-world problems often get in the way. One major issue is externalities—when a transaction affects people who aren’t directly involved. Negative externalities, like pollution, impose costs on others without compensation. A steel factory dumping waste into a river harms nearby farmers, yet the factory has no reason to stop unless regulations or taxes force it to consider these hidden costs.Another...

First Welfare Theorem I

The First Welfare Theorem explains how resources are allocated efficiently in perfectly competitive markets. It states that in these markets, competitive equilibrium leads to Pareto efficiency, meaning no one can be made better off without making someone else worse off.Imagine two neighbors living in a rural area. One has a surplus of firewood, essential for heating during cold nights, while the other has access to clean water from a nearby spring. The first neighbor values water more, as it’s...

Second Welfare Theorem

The Second Welfare Theorem states that any Pareto-efficient allocation can be reached with proper redistribution. It suggests that an equitable initial allocation of resources can be established through redistribution, and subsequently, markets can operate unhindered to achieve efficiency.Imagine two farmers. One has many seeds but little land, while the other has plenty of land but few seeds. Without adjusting prices, redistributing some land to the first farmer and some seeds to the second...

Researchers combine observations of environmental conditions, nutrition, health, behavior, and physiological indicators such as stress responses. This multidimensional approach recognizes that an animal may appear physically healthy while experiencing problems related to its surroundings or inability to express important natural behaviors. Considering several evidence types produces a more complete biological assessment.
Behavior can reveal how an animal experiences its surroundings, complementing information from health measurements and physiological responses. Changes in behavior may indicate that environmental conditions, nutrition, or care are affecting well-being, even when obvious illness is absent. Monitoring behavior therefore helps identify welfare concerns that would not be captured by physical observations alone.
Environmental conditions affect welfare because animals respond to the surroundings in which they live, receive care, or undergo research. Assessment therefore considers whether those conditions support health, reduce unnecessary suffering, and allow important natural behaviors. This perspective links housing and husbandry decisions with both observable outcomes and the animal’s experience.
Humane welfare practices can improve data quality in research by supporting the health and well-being of laboratory animals. Researchers must therefore consider welfare alongside experimental aims, using observations of health, behavior, environmental conditions, nutrition, and physiological stress responses to inform care. Better-informed husbandry can support more reliable research while strengthening ethical decision-making.
A practical assessment begins by examining the animal’s environment, nutrition, health, and behavior, then considers relevant physiological indicators such as stress responses. Researchers interpret these observations together rather than relying on one measure. The resulting evaluation can guide changes in husbandry, laboratory-animal care, veterinary practice, agriculture, or wildlife management.
Biological welfare principles guide humane husbandry, laboratory-animal care, veterinary practice, agriculture, and wildlife management. In each setting, researchers or practitioners can evaluate conditions affecting health, behavior, nutrition, and physiological responses, then use that information to support ethical decisions. The same framework is adaptable because welfare depends on how animals experience their surroundings.
In veterinary and agricultural settings, welfare assessment brings together evidence about health, nutrition, environmental conditions, behavior, and stress responses. This information helps identify whether current care supports well-being or contributes to unnecessary suffering. Applying the findings can improve husbandry decisions and encourage more sustainable relationships between humans and animals.
