    Administering colostrum to calves via nipple bottle or esophageal tube resulted in similar immunoglobulin G (IgG) concentrations. Both methods provided adequate IgG levels for calf survival, indicating comparable efficacy in passive transfer.

    Area of Science:

    • Veterinary Medicine
    • Animal Science
    • Neonatal Calf Care

    Background:

    • Passive transfer of immunity is crucial for calf health.
    • Immunoglobulin G (IgG) is a key component for neonatal immunity in calves.
    • Effective colostrum administration methods are vital for ensuring adequate IgG absorption.

    Purpose of the Study:

    • To compare the efficacy of two colostrum administration methods: nipple bottle versus esophageal tube.
    • To evaluate the impact of administration route on serum immunoglobulin G (IgG) concentrations in newborn calves.
    • To determine if differences exist in IgG absorption rates and final concentrations between the two methods.

    Main Methods:

    • Calves received pooled colostrum via nipple bottle or esophageal tube shortly after birth, and at 12 and 24 hours.

  • Blood samples were collected pre-feeding and every 4 hours up to 32 hours post-initial feeding.
  • Serum samples were analyzed for immunoglobulin G (IgG) concentrations.

    • Main Results:

    • The rate of serum IgG increase was comparable between calves fed by nipple bottle and esophageal tube.
    • Serum IgG concentrations at 20 hours post-initial feeding were similar for both administration groups.
    • Achieved IgG concentrations were adequate to ensure calf survival, regardless of the feeding method.

    Conclusions:

    • Both nipple bottle and esophageal tube methods are effective for colostrum administration in calves.
    • The route of colostrum delivery does not significantly impact the rate or extent of IgG absorption in the early hours post-birth.
    • Both methods support successful passive transfer of immunity, crucial for neonatal calf health and survival.
