Transition management in the field - a step by step guide to transition success

摘要

During the transition period cows suffer from negative energy balance (NEB) and immune suppression (IS), which depending on the degree and duration will increase the risk of post-calving disease. Management factors (such as housing and environment), cow factors (such as body condition score [BCS] and lameness), and the quality, quantity and accessibility of feed and water that is provided for dry cows will to a large extent determine the degree and duration of NEB and IS and consequently has an impact on the amount of post-calving disease seen. Using management assessment and intervention, monitoring tools and product placement, we can have a positive impact on the journey of a transition cow, decrease the degree of immune suppression and negative energy balance experienced and consequently decrease post-calving disease. This is beneficial for the health, welfare and productivity of the cow and the profitability of the farm.
