Overview

Investigation reveals colostrum type impacts immunity in neonatal lambs, suggesting optimal choices for health.

Key Points

  • Lambs receiving fresh ewe colostrum showed a higher trend in IgG levels compared to frozen colostrum at later ages, indicating better passive immunity.
  • Frozen cattle colostrum led to significantly higher IgG concentrations than artificial cattle colostrum during the first three weeks post-birth.
  • Lambs immunized with fresh ewe colostrum exhibited a faster and stronger immune response to ovalbumin than those receiving frozen cattle colostrum.
  • This study highlights how the colostrum source can significantly influence immune development in newborn lambs.
