Management systems and client goals are integral components of clinical nutrition and vary among and within sheep and goat producers. Evaluation includes client interview and history taking, record examination, forage analyses, animal examination, and occasionally blood or tissue assays. The types of nutritional disorders that are likely to be observed in sheep and goats vary according to the type of management and can be grouped according to feedlot, intensive production, farm flocks, dairy, and browse systems. Examples described include nutritional problems that may be overlooked (water deprivation), widespread (energy imbalance), currently difficult to prevent and treat (selenium deficiency), and reflective of soil-plant-animal complexities (copper-molybdenum balance).
管理系统和客户目标是临床营养的重要组成部分，在绵羊和山羊养殖户之间以及养殖户内部各不相同。评估包括与客户面谈和采集病史、检查记录、分析草料、检查动物，偶尔还包括血液或组织检测。绵羊和山羊中可能观察到的营养失调类型因管理方式而异，可根据饲养场、集约化生产、农场畜群、奶牛场和放牧系统进行分类。所描述的例子包括可能被忽视的营养问题（缺水）、普遍存在的问题（能量失衡）、目前难以预防和治疗的问题（硒缺乏）以及反映土壤 - 植物 - 动物复杂关系的问题（铜 - 钼平衡）。
