Nutrition is a relevant factor for optimizing performance and promoting animal welfare in intensive and semi-intensive farming systems, through the formulation and supply of diets capable of meeting nutritional needs. The effects of providing unbalanced diets or diets that contain goitrogenic substances are reflected through the occurrence of metabolic dysfunctions, such as thyroid gland endocrinopathies (hypothyroidism, hyperthyroidism and goiter). In this context, the aim of this article was to gather information about the effects of nutrients and goitrogenic substances on the thyroid function of production animals and to show the impact on their performance. To achieve the purpose of the study, information obtained through academic research tools such as SciELO, Google Scholar, Portal de Periódicos CAPES, BVS-Vet (Virtual Library of Veterinary Medicine and Animal Science), CAPES Theses Bank and BDTD ( Brazilian Digital Library of Theses and Dissertations). Thus, it was concluded that thyroid dysfunctions are common to all animal species and caused by several factors such as excess or lack of dietary iodine, presence of goitrogenic substances in foods of plant origin, lack of zinc, selenium and excess calcium. Thyroid dysfunctions are responsible for delaying animal performance in terms of feed conversion, not to mention that they are directly linked to a greater occurrence of reproductive problems such as retained placenta, abortions and stillbirths.
