“…In this regard, the metabolic path of Se is dependent on the source employed (Ortman and Pehrson, 1999;Juniper et al, 2008;Slavik et al, 2008), with selenite being more easily metabolized to the immediate precursors of selenocysteine in comparison with the organic forms of Se. The barium selenate (BaSeO4) is an inorganic source that has been used in the formulation of prolonged-release preparations to provide an adequate Se status for at least 7 months (Leyán et al, 2004;Judson and Badidge, 2010), generating a high and sustained concentration of Se in plasma and liver compared to other inorganic forms (Davis et al, 2008).…”

“…Trace mineral supplementation has been shown to alter colostrum quality in dairy cows, but responses may be dependent upon both the individual trace minerals and their formulation. Selenium supplementation of the precalving dairy cow diet has been shown to increase ( Pavlata et al, 2004 ), decrease ( Leyan et al, 2004 ), or have no effect on ( Mohrekesh et al, 2019 ) colostrum Ig. Chromium-methionine supplementation (during the dry period) of pregnant dairy cows did not alter either colostrum quantity or quality ( Gultepe et al, 2018 ).…”

“…The formulation and dose rate of the mineral supplement may matter. Prenatal parenteral selenium administration to dairy cows has been shown to reduce offspring serum Ig content ( Leyan et al, 2004 ). Dairy cows supplemented with organic trace elements had significantly higher colostrum IgG content compared with cows supplemented with inorganic minerals in most ( Kincaid and Socha, 2004 ; Formigoni et al, 2011 ; Roshanzamir et al, 2020 ) but not all studies ( Juniper et al, 2019 ).…”

Graphical Abstract Summary: The transgenerational metabolic-disease complex is shown. DMI = dry matter intake; BCS = body condition score; EFG = excessive fetal growth; FGR = fetal growth restriction; FPT = failure of passive transfer of immunoglobulin (Ig); MN = macro/micronutrient, ill thrift = slower growth rate than expected given feed allocation; birth wt. = birth weight. The arrows imply “associated with” and the text uses key words to highlight components of the complex.

Osteopathology and selenium deficiency co-occurring in a population of endangered Patagonian huemul (Hippocamelus bisulcus)

BackgroundAbout 1,000 endangered Patagonian huemul deer (Hippocamelus bisulcus) remain in Chile and 350–500 in Argentina. Most groups (>100) are not recovering, and prevalence of osteopathology in Argentina was at least 57%. Here I describe relevant cases of osteopathology from a Chilean population which, however, recently also provided data on trace mineral status, supporting the initial hypothesis that nutrition may be a primary etiologic factor. Additionally, recent data on bone chemical composition of Argentine cases and soil analyses are discussed.ResultsFluoride levels in Argentine cases with osteopathology were low and fluorosis was discarded as an etiological factor. Selenium deficiency occurred in 73% of huemul from the Chilean population which exhibited several cases with osteopathology. The pathophysiognomy included extensive erosion; tooth loss; porosification; perforations of palate, maxillar and mandibular bone with frequent exposure of tooth roots; and fractured mandibula. Areas currently used by remaining huemul have mainly acidic volcanic soils, which reduces selenium bioavailability: mean soil selenium levels from areas typically used by extant huemul were very deficient (0.19 ppm), corroborating documented overt selenium deficiency in local livestock and plants. The area of extant huemul is known to result in primary iodine deficiency in livestock which is aggravated by selenium deficiency.ConclusionsCurrently the most parsimonious explanation for frequent osteopathology and lack of numerical recovery are the combined effects of selenium and iodine deficiencies based on: osteopathology in a population of selenium deficient huemul; selenium deficient livestock, plants and soils; acidic soils; and regional primary iodine deficiency. The nexus between mineral nutrition and population dynamics of huemul may be due to constraints on their movements to fertile lowlands, including the elimination of historic migratory traditions, and concomitant elimination of source populations.
