Invited review: Management strategies capableof improving the reproductive performance ofheat-stressed dairy cattle. By Negrón-Pérez et al.,page 10695. Heat stress is detrimental to the productivityof dairy cattle and negatively affects their fertility.The physiological mechanisms responsible for theobserved reduction in reproductive performance duringheat stress are many and varied, including direct andindirect consequences of elevated temperature. Decadesof research experiments have been aimed at identifyingmanagement strategies capable of improving reproductionin heat-stressed dairy cattle. Investigated approachesencompass a myriad of opportunities, rangingfrom feed supplements to bull selection and embryotransfer. This invited review focuses on strategies thathave demonstrated effectiveness and could be appliedon-farm.
