Hypocalcaemia, or milk fever, is a common issue in dairy farming. Cows with milk fever are at greater risk of other metabolic disorders so prevention should be the focus. Prevention usually involves manipulation of the close-up diet.
Environmental and nutritional modifications can be implemented to address the challenges of heat stress. The main goal of nutritional management during heat stress is to maintain a healthy rumen function while providing optimal nutrient supply to limit the negative energy balance situation.
Metabolic disorders are extremely costly to dairy farmers and the overall cost is certainly greater than the direct loss of income from reduced milk production. Most metabolic disorders are not "stand-alone" – the occurrence of one tends to increase the risk of another. Nutrition is probably the most influential and most often considered when looking at management practices to address metabolic issues, but cow comfort and hygiene are also crucial.
