    Area of Science:

    • Laboratory animal science
    • Animal husbandry
    • Comparative nutrition

    Context:

    • Optimizing animal care and research outcomes requires efficient and reliable feeding systems.
    • Conventional feeders for powdered diets often lead to significant wastage and contamination.
    • There is a need for improved feeding solutions for powdered diets in small rodent research.

    Purpose:

    • To develop and evaluate a new feeder designed for powdered diets in small rodents.
    • To assess the feeder's efficiency in terms of food wastage, intake measurement, and adaptability.
    • To compare the growth rates of rodents using the new feeder with those using conventional methods.

    Summary:

    • A new feeder for powdered diets was developed and tested on weanling and adult rats, and adult hamsters.
    • Growth rates were comparable between animals fed powdered diets from the new feeder and those fed pelleted or powdered diets from conventional feeders.
    • The new feeder demonstrated minimal wastage (1-2%), prevented fecal/urine contamination, and was easy to handle and clean.

    Impact:

    • Provides a cost-effective and reliable method for feeding powdered diets to laboratory rodents.
    • Facilitates accurate monitoring of food intake, crucial for metabolic and nutritional studies.
    • Enhances animal welfare by ensuring a continuous, uncontaminated food supply, potentially improving research reproducibility.
