Dr. Juan Loor, Associate Professor in the Department of Animal Sciences at the University of Illinois, represented ASAS at the 68th EAAP Annual Meeting, held August 28 – September 1 in Tallinn, Estonia.
Dr. Loor gave an invited talk at the meeting as part of an ASAS-EAAP speaker exchange. His presentation was entitled "Nutrition and immunometabolic adaptations to lactation in dairy cows: role in performance and health."
Dr. Loor provided the following summary of his presentation:
Immunometabolism represents the interface between immunology and metabolism, and is an emerging field of investigation in livestock biosciences. At the core of this concept is the recognition of “multilevel interactions between metabolic and immune systems,” implying “cross-talk” or “communication” among key cells and organs, which are orchestrated by unique mechanisms and their effectors. Such mechanisms correlate closely with health or disease status. The field of immunometabolism as it pertains to periparturient dairy cows is in its infancy. The advent of high-throughput technologies in the past decade has allowed the exploration of interrelationships among metabolic and immune systems. Ongoing focus is on the bi-directional communication between immune and metabolic cells with signaling molecules derived intrinsically or as a result of intermediary metabolism or immune responses in tissues such as liver, adipose, and skeletal muscle. Macro and micronutrients are important effectors in the regulation of the immunometabolic response of the cow with effects often broad in nature. These responses are of great importance during the adaptation phase to lactation, as they seem to be key determinants of feed intake and milk production, reproduction, and health status. A better understanding of the multilevel interactions among the various components of the metabolic and immune systems during the periparturient period has already led to identification of mechanisms that underlie certain complications afflicting cows. Future research in this area should lead to promising therapeutic approaches.
