Source: Kay Stewart, RVT, RLATG, CMAR; Valerie A. Schroeder, RVT, RLATG. University of Notre Dame, IN Millions of mice and rats are bred for use in biomedical research each year. Worldwide, there are several large commercial breeding facilities that supply mice to research laboratories, but many facilities also choose to breed mice and rats in-house to reduce costs and increase research options. When breeding in the animal facility, researchers are able to manipulate the genetics of the...

Inspiratory Muscle Training as an Adjunct to the Treatment of Weaning Failure in Critically Ill Patients: A Practical Guide
0 Views •
2026
Respiratory muscle weakness is highly prevalent in patients weaning from mechanical ventilation. Resistive inspiratory muscle training (IMT) can improve inspiratory strength and potentially weaning outcomes. This protocol provides a structured approach to offer IMT to selected patients based on the best available knowledge, facilitating its wider application in critical care.

Neutrophils are among the first cells to arrive on the site of inflammatory immune response, and their functions and mechanisms have been studied extensively in vitro. We demonstrate a standard density gradient separation method to isolate human neutrophils from whole blood using commercially available separation media.

Porcine models of organ transplantation provide an important platform to study mechanisms of organ preservation. This article describes a heterotopic porcine renal autotransplantation model, which allows investigating new approaches to improve the outcome of transplantation using marginal kidney grafts.
FAQs
Gradual dietary change gives the digestive system, feeding behavior, and metabolism time to adjust as nursing decreases. This reduces the mismatch between declining maternal milk or formula and increasing independent intake. In a biological study, that adjustment helps maintain normal growth and makes developmental conditions more consistent across young animals.
These elements provide complementary parts of the transition. Access to solid food supports movement toward independent feeding, while water becomes increasingly relevant as reliance on milk or formula decreases. At the same time, nursing is reduced rather than treated as an unrelated behavior, allowing feeding patterns and metabolism to adapt together.
Young mammals do not reach the same feeding or digestive milestones at identical times. Species and developmental stage therefore influence when independent feeding can be introduced and how quickly nursing should decline. Matching the protocol to these conditions supports normal growth and prevents comparisons from being confounded by different developmental schedules.
A practical sequence establishes the developmental timing, introduces or maintains access to solid food and water, and gradually decreases maternal milk or formula. The transition is then managed under consistent conditions so feeding behavior, digestive adaptation, metabolism, and growth can adjust together. The exact timing depends on species and developmental stage.
They are particularly useful in breeding colonies and studies examining nutrition, growth, behavior, or disease. A shared protocol keeps early-life feeding conditions comparable among animals, which strengthens interpretation of later measurements. Without that consistency, differences in the timing or manner of transition could influence developmental outcomes independently of the research question.
Early-life feeding conditions can influence later development, so the transition itself is an important experimental variable. Consistent timing and management help researchers distinguish effects related to nutrition, growth, behavior, or disease from effects caused by unequal early feeding experiences. The protocol also supports animal welfare by reducing stress during a major developmental change.
