The major histocompatibility complex in bovines: a review

Area of Science:

• Veterinary Immunology
• Animal Genetics

Background:

• Dairy cattle and buffalo productivity are influenced by genetic factors affecting milk production and disease resistance.
• The vertebrate immune system is a complex network protecting against pathogens and diseases.
• The Major Histocompatibility Complex (MHC) is crucial for immune system development and function in mammals.

Purpose of the Study:

• To explore the role of genetic factors, particularly the MHC, in dairy animal productivity and disease resistance.
• To understand the immune system's complexity and its relation to animal health.

Main Methods:

• Review of existing literature on dairy animal genetics and immunology.
• Focus on the function and significance of the Major Histocompatibility Complex (MHC) in mammalian immune responses.

Main Results:

• Genetic factors significantly impact milk yield, milk composition, and disease resistance in dairy animals.
• The MHC is a critical genetic region involved in immune response, self/non-self discrimination, and susceptibility to various diseases.
• MHC genes influence the acceptance or rejection of transplanted tissues.

Conclusions:

• Understanding the genetic basis of immunity, especially MHC, is vital for improving dairy animal health and productivity.
• Targeting MHC genes could offer strategies for enhancing disease resistance in livestock.
• Further research into MHC's role can lead to advancements in animal breeding and disease management.
