Cold resistance and environmental temperature preference in diarrheic piglets.

R K Balsbaugh, S E Curtis, R C Meyer

    Journal of Animal Science
    |February 1, 1986
    PubMed
    Summary

    Diarrheic piglets struggle to maintain body temperature in cold conditions and do not seek warmer environments. Neonatal piglet diarrhea requires increased thermal management for their well-being.

    Area of Science:

    • Animal Physiology
    • Neonatal Health
    • Environmental Stress Response

    Background:

    • Diarrhea in neonatal piglets compromises thermoregulation.
    • Enteric infections and induced diarrhea can impact piglet physiology.
    • Understanding thermal regulation is crucial for piglet survival.

    Purpose of the Study:

    • To investigate the cold resistance of diarrheic piglets.
    • To assess the thermal-circulation index in piglets with diarrhea.
    • To determine the preferred environmental temperature of diarrheic piglets.

    Main Methods:

    • Two experiments were conducted on piglets aged 12 to 72 hours.
    • Experiment 1: 90-min cold test at 6°C to assess cold resistance and thermal-circulation index.
    • Experiment 2: 60-min thermocline test (24-44°C) for temperature preference.

    Main Results:

    • Diarrhea significantly reduced piglets' ability to maintain body temperature in a cold environment.
    • Diarrheic piglets exhibited a greater vasoconstrictive response to cold.
    • Contrary to expectations, diarrheic piglets did not select warmer temperatures, preferring cooler niches.

    Conclusions:

    • Diarrheic neonatal piglets have impaired thermoregulation and cold tolerance.
    • Neonatal piglet diarrhea necessitates enhanced attention to thermal environment management.
    • Further research is needed to understand the reasons behind altered temperature preferences in diarrheic piglets.
