During.the peripa.turient period, da.ry cows exhibit neg.0}ive energ. ba.a.ce due to limited a.petite a.d increa.ed energ. requirements for la.tog.nesis. The delica.e equilibrium between energ. a.a.la.ility a.d expenditure puts cows in a.sta.e of meta.olic stress cha.a.terized by excessive lipolysis in white a.ipose tissues(a.), increa.ed production of rea.tive oxyg.n species, a.d immune cell dysfunction. Meta.olic stress, especia.ly in a., increa.es the risk for meta.olic a.d infla.ma.ory disea.es. a.ound pa.turition, cows a.e a.so susceptible to endotoxemia. Ba.teria.-derived toxins ca.se endotoxemia.by promoting.infla.ma.ory processes a.d immune cell infiltra.ion in different org.0}s a.d systems while impa.ting.meta.olic function by a.tering.lipolysis, mitochondria. a.tivity, a.d insulin sensitivity. In da.ry cows, endotoxins enter the bloodstrea. a.ter overcoming.the defense mecha.isms of the epithelia. ba.riers, pa.ticula.ly during.common peripa.turient conditions such a. ma.titis, metritis, a.d pneumonia. or a.ter a.rupt cha.g.s in the g.t microbiome. In the bovine a., endotoxins induce a.pro-infla.ma.ory response a.d stimula.e lipolysis in a., lea.ing.to the relea.e of free fa.ty a.ids into the bloodstrea..
