Husbandry methods predisposing to production diseases in dairy cows

Area of Science:

• Veterinary Medicine
• Animal Husbandry
• Livestock Management

Background:

• Disease in livestock can stem from various management practices beyond nutrition.
• Environmental and handling factors significantly influence animal health and productivity.
• Nutritional deficiencies or imbalances are linked to specific metabolic diseases and reproductive issues.

Purpose of the Study:

• To identify and describe non-nutritional management errors predisposing livestock to disease.
• To outline nutritional factors affecting conception rates and metabolic diseases.
• To provide a comprehensive overview of disease causation in livestock management.

Main Methods:

• Review and description of common management errors.
• Identification of environmental and handling factors contributing to specific diseases (lameness, mastitis).
• Explanation of breeding practices leading to dystocia and observation issues affecting oestrus detection.
• Outline of nutritional impacts on conception, ketosis, hypocalcaemia, and hypomagnesaemia.

Main Results:

• Management errors such as abrasive surfaces, prolonged slurry standing, faulty milking, and poor hygiene are linked to lameness and mastitis.
• Breeding for oversized fetuses can cause dystocia, and inefficient observation hinders oestrus detection.
• Specific nutritional factors negatively affect conception rates and contribute to metabolic diseases like ketosis, hypocalcaemia, and hypomagnesaemia.

Conclusions:

• Non-nutritional management practices are significant contributors to disease incidence in livestock.
• Addressing environmental, handling, and breeding management is crucial for disease prevention.
• Optimizing nutrition is essential for reproductive success and preventing metabolic disorders in livestock.
