摘要: Metabolic disorders are a key problem in the transition period of dairy cows and often appear before onset further health problems. They mainly derive from difficulties animals have adapting to changes disturbances occurring both outside inside organisms due varying gaps between nutrient supply demand. Adaptation is functional target-oriented process involving whole organism thus cannot be narrowed down single factors. Most problems which challenge can solved number different ways. To understand mechanisms adaptation, interconnectedness variables flow within metabolic network need considered. indicate an overstressed ability balance input, partitioning output variables. Dairy will more easily succeed avoiding dysfunctional processes when gap energy demands their restricted. farms vary widely relation living conditions animals. The complexity nutritional Animals 2015, 5 979 large variations on various scales contradict any attempts predict outcome animals’ adaptation farm specific situation. Any reduce prevalence associated production diseases should rely continuous comprehensive monitoring with appropriate indicators level. Furthermore, low levels seen as significant goal carries weight addition productivity goals. In long run, disease only expected farmers realize that they gain competitive advantage over competitors higher disease.
