M. de  aOrganic selenium supplementation on metabolic profile of dairy goats.h[electronic resource]  c2023  aAbstract: The aim of this study was to evaluate the effect of organic selenium (SE) supplementation on blood constituents related to hematology and serum biochemistry of dairy goats in the productive phase. A total of 16 lactating Saanen?×?Toggenburg crossbred goats, aged between 2 and 3, lactating, nonpregnant, clinically healthy, and having a body weight (BW) of 40.75?±?8.31 kg were selected for this study. Higher SE concentrations were observed on the 42nd day of supplementation, and on the 63rd day, the SE concentrations were similar (P&gt0.05&gt0.05) to the 21st and 42nd days. There was no interaction for plasma constituents comparing treatment effects and days of supplementation (P&gt0.05&gt0.05). SE supplementation reduced (P=0.04=0.04) plasma proteins with a gradual increase in available SE. There was no difference (P&gt0.05&gt0.05) for the blood count comparing the effects of treatment and days of supplementation. There was no interaction (P&gt0.05&gt0.05) for serum biochemical constituents between treatments and periods, except for urea (P=0.045=0.045). Animals that received SE supplementation had similar plasma urea concentrations before and after supplementation, while animals that did not receive SE in the diet had increased serum urea concentrations. The main action of selenium in metabolism occurred in the reduction of plasma proteins and urea levels, which leads us to conclude that it influenced protein metabolism. Finally, hematology, liver function, and energy metabolism are not affected by selenium supplementation in dairy goats reared in semiarid conditions.  aBiochemical compounds  aBlood serum  aBrazil  aDairy goats  aDietary mineral supplements  aDietary supplements  aHematology  aImmunity  aLactation  aLiver function  aMetabolism  aProtein metabolism  aRuminant nutrition  aSelenium  aSemiarid zones  aSmall ruminants  aCabra Leiteira  aCaprino  aLactação  aMetabolismo Protéico  aNutrição Animal  aSelênio  aSuplemento Mineral  aSuplemento Protéico  aBlood tests  aHomeothermy  aSemiarid region1 aRIOS, M.
