Résumé:
This review aimed to address the importance of the influence bioclimatology on blood profile and the thermal comfort of dairy cows based on environmental factors, and the production of milk, from reports in current literature. Information were addressed, the majority of published articles that reflect the importance of the use of shading, both natural and artificial facilities on the milk production of lactating dairy cattle. From what was observed, found that dairy cows have their production directly influenced by environmental conditions in which they operate, which is evidenced by the changes occurring in haematological values of these animals. As resources for improvement of thermal discomfort have been the use of shading and cooling systems, that may contribute to the increase in milk production of these animals, therefore, the use of these strategies, of great relevance for dairy cattle raising.
