Area of Science:

  • Veterinary immunology
  • Animal genetics
  • Dairy science

Background:

  • Mastitis is a costly dairy industry disease impacting milk production and quality.
  • Current control methods, including management and genetics, are insufficient.
  • Bacterial infections cause mammary gland inflammation, leading to economic losses.

Purpose of the Study:

  • To review genetic regulation of the bovine immune system for disease resistance.
  • To highlight novel genetic strategies for reducing mastitis incidence.
  • To explore the role of enhanced immune response in dairy cattle.

Main Methods:

  • Review of scientific literature on bovine immunology and genetics.
  • Analysis of genetic selection approaches for disease resistance.
  • Focus on high immune response (HIR) technology and genomic selection.

Main Results:

  • Enhanced and balanced immune responses in cattle correlate with lower mastitis incidence.
  • High immune response (HIR) technology aids in identifying and selecting disease-resistant animals.
  • Improved immunity is linked to better vaccination response, milk/colostrum quality, longevity, and reproduction.

Conclusions:

  • Genetic selection for improved immune responsiveness offers a promising strategy for mastitis control.
  • This approach enhances animal welfare and food quality while maintaining production levels.
  • Future dairy industry practices should integrate advanced genetic tools for disease resistance.
