“…Las leguminosas acumulan menor cantidad de Se que las gramíneas, si bien el Lolium sp., gramínea ampliamente utilizada en sur de Chile, presenta menor contenido de Se que la alfalfa o gramínea bermudas (2). Además existen diversos factores de riesgo para la carencia de Se y presentación de cuadros clínicos, como acidez del suelo, alto contenido de hierro y azufre, heno contaminado con hongos y dietas ricas en grasas no saturadas (1,8).…”

RESUMENObjetivo. Dos experimentos se realizaron para determinar el estatus de selenio en equinos Criollo-Chileno a pastoreo y, evaluar la respuesta a la suplementación con Na2SeO3. Materiales y métodos. Exp.1A caballos pertenecientes a 10 criaderos del sur de Chile se les determinó la actividad sanguínea de glutatión peroxidasa (GPx, EC.1.11.1.9) (AcGPx). Los animales pertenecieron a 3 grupos, pastoreo de otoño (PO, n=40), pastoreo de otoño y suplementados con avena (PO+A, n=47), y, pastoreo de primavera (PP, n=41). Exp2Se utilizaron equinos con carencia de selenio, distribuidos en tres grupos: G1, n=7, tratado con Na2SeO3 el día 0 (Se= 0.05 mg/kg pv, im); G2, n=8, suplementado con Na2SeO3, los días 0 y 15 y GC, n=8, control. La AcGPx se determinó al día 0, 30 y 120. Resultados. La mediana (Me) de la AcGPx en todos los grupos fue menor al límite adecuado (>130 U/gHb), mayor en PO+A (Me=92, P25%=47, P75%=129 U/gHb) y PP (Me=85, P25%=45, P75%=114 U/gHb) que en PO (Me=35, P25%=20, P75%=85 U/gHb) (p<0.05). En el experimento 2 la AcGPx fue similar y menor al adecuado en todos los grupos. La suplementación con Na2SeO3 aumentó (p<0.05) la AcGPx en G1 (121±52 U/gHb) y G2 (124±69 U/gHb), sin alcanzar valores adecuados. Conclusiones. Los equinos Criollo-Chileno a pastoreo en el sur de Chile presentan carencia de Se, mayor en otoño que primavera y menor al suplementar con avena. Adicionalmente, la administración parenteral de Na2SeO3 mejora el estatus de Se, pero sin revertir el cuadro carencial.

The Role of Selenium in Controlling Reproductive Disorder in Beef Cattle

Reproductive failure is regarded as a problem in the breeding of beef cattle as indicated by low calving rate, low conception rate, longer periods of calving interval, and neonatal mortality. Selenium deficiency may lead to non-infectious reproduction disorder in ruminants. The purpose of this review is to evaluate the role of selenium in preventing reproduction failure of beef cattle. In the reproduction process, selenium is required for cellular respiration, cellular oxidation, DNA and RNA replication, the integrity of cells membrane, and releasing free radicals. Selenocysteine (SeCys) is the main component of selenoprotein consisting of glutathione peroxidase (GPX) to inhibit free radicals formation and reduce risks of tissue damage. Glutathione peroxidases (GPXs) involved are: GPX-1 (cytosolic), GPX-2 (gastrointestinal specific), GPX-3 (plasma/extracellular), GPX-4 (phospholipid-hydroperoxides/intracellular) and GPX-5 (spermatozoa mitochondrial capsule). Selenium as an antioxidant is potentially involved in reducing fertility, stillbirth, abortus, and premature in cows based on oxidative stress and selenium deficiency. In male cattle, the role of selenium is to maintain the integrity of cells membrane, spermatozoa fertility, and ejaculation. The selenium deficiency may therefore affect spermatozoa fertility, motility, and fusion to oocytes due to lipid peroxidation. It is then regarded as a factor in reproductive failure mainly in the infertility of cattle. Treatments for reproductive failure due to selenium deficiency could be conducted by supplementing selenium in the mineral mix, periodical dosing of selenium salt, and providing Se-mineral block, the combination of selenium and vitamin E or selenium supplementation in soils to improve the quality of fodder and feeds.

Selenium and vitamin E protect the body against oxidative stress. Clinical manifestations of their deficiency in equids include neurologic and muscular symptoms. Despite the importance of donkeys as working and production animals, there is a dearth of scientific data on selenium and vitamin E normal values. Therefore, the aim of this study was to investigate the plasma concentrations of selenium and vitamin E in healthy donkeys belonging to different ages, sexes, and productive phases. Animals were divided into five groups including foals (group A: n ¼ 7, n ¼ 4 males and n ¼ 3 females), weanlings and yearlings (group B: n ¼ 7, n ¼ 2 males and n ¼ 5 females), nonpregnant nonlactating jennies (group C: n ¼ 5), pregnant nonlactating jennies (group D: n ¼ 9), and adult males (group E: n ¼ 9). Plasma samples obtained from each animal were tested for vitamin E and selenium concentration. One-way analysis of variance showed significant differences in selenium concentrations (P ¼ .001) between group A and group E. In this study, we found the selenium range for donkeys to be 0.02e0.14 mg/mL, which is lower than the recommended range for horses. The results suggest that donkeys may have a lower selenium requirement than horses. Plasma vitamin E levels were 3.29e12.99 mmol/L, with foals having lower concentrations than adults. Knowing specific reference ranges for vitamin E and selenium in healthy donkeys can help improve our understanding of how to prevent deficiencies that could compromise their overall health and well-being.
