Errors in management, other than nutrition, which can be predisposing causes of disease, eg, walking on abrasive surfaces and prolonged standing in slurry (which precipitate lameness), faulty milking and a dirty environment (which are conducive to mastitis), breeding to produce oversized fetuses (leading to dystocia) and inefficient observation (leading to a failure to detect oestrus) are described. Nutritional factors affecting conception rates and the occurrence of the metabolic diseases, ketosis, hypocalcaemia and hypomagnesaemia are outlined.
除营养外，管理方面的失误也可能是疾病的诱发原因，例如在粗糙地面行走和长时间站在泥浆中（可引发跛行）、挤奶操作不当和环境肮脏（易导致乳腺炎）、繁育出过大胎儿（导致难产）以及观察不充分（导致无法检测到发情）。文中还概述了影响受孕率以及代谢疾病、酮病、低钙血症和低镁血症发生的营养因素。
