Nutritional strategies to optimize dairy cattle immunity

Area of Science:

• Veterinary Medicine
• Animal Nutrition
• Immunology

Background:

• Periparturient dairy cattle face high risks of metabolic and infectious diseases.
• Uncontrolled inflammation is a common factor in diseases like mastitis, metritis, and ketosis.
• Nutritional status critically influences bovine immune cell function.

Purpose of the Study:

• To review the complex interactions between nutrient metabolism and immune function in periparturient dairy cattle.
• To detail how macro- and micronutrient imbalances affect immune dysfunction and disease.
• To explore the interplay of altered nutrient metabolism, oxidative stress, and immune compromise in transition cows.

Main Methods:

• Literature review focusing on the interplay between nutrition and immunity in dairy cattle.
• Analysis of how nutrient deficiencies and overexposure impact immune mechanisms.
• Examination of the role of oxidative stress in immune system compromise.

Main Results:

• Nutritional status and nutrient metabolism are critical regulators of immune cell function.
• Disturbances in nutritional or immunological homeostasis create detrimental feedback loops.
• Altered nutrient metabolism and oxidative stress synergistically compromise the immune system in transition cows.

Conclusions:

• Understanding the nutrition-immunity link is crucial for managing periparturient dairy cattle health.
• Optimized nutritional strategies can reduce disease susceptibility in early lactation.
• This knowledge can improve dairy food safety and availability.
