“…Morris et al (1984) recently reported that Se supplementation increased weaning weights of calves grazing pasture containing .020 to .055 mg/kg of Se. In other studies (Shirley et al, 1966;Hidiroglou and Jenkins, 1975), Se supplementation of nurs- ing calves grazing pasture or being fed Se deficient roughages did not improve calf gains. Protein supplementation of cows improved (P<.01) calf gains during the winter phase (table 1).…”

“…Long-term studies with beef cattle residing in geographical areas considered marginally or extremely deficient in Se are limited and the results obtained have been inconsistent (Shirley et al, 1966;Hidiroglou and Jenkins, 1975;Scales, 1976;Morris et al, 1984). The objectives of the present study were: 1) to determine the effects of Se-vitamin E (E) injections on growth, reproduction and Se status of beef cattle receiving feeds marginally deficient in Se and 2) to evaluate the influence of protein supplementation during the winter on cattle performance and response to Se-E injections.…”

Seventy-two Hereford X Simmental cows, averaging 498 kg in body weight and 5.2 yr of age, were used in a 2-yr study to ascertain if selenium (Se)-vitamin E (E) injections and winter protein supplementation would affect growth, reproduction and health of beef cattle maintained year-round on feedstuffs marginally deficient in Se (.03 to .05 mg/kg). Cows received either no injection or a mixture of 30 mg Se (as sodium selenite) and 408 IU E injected subcutaneously beginning 3 to 4 mo prepartum and at 60-d intervals throughout the 2-yr period. Calves born to Se-E treated cows were injected with 5.5 mg Se and 75 IU E/100 kg body weight at 60-d intervals beginning at 1 mo of age. Calves were born between December 30 and February 20 and cows were bred between March 20 and May 20. Cattle grazed pasture (.05 mg Se/kg) that consisted of orchardgrass, bluegrass and white clover during the fall, spring and summer. During winter (December 15 to May 2), cattle were fed corn silage (.03 mg Se/kg) supplemented with either: no protein supplement (control), soybean meal or a urea-corn mixture. Cows and calves receiving Se-E had higher (P less than .01) whole blood glutathione peroxidase (GSH-Px) activity and plasma Se concentrations than controls. Selenium-E injections reduced (P less than .05) calf death losses from 15.3% to 4.2% and slightly increased (P less than .10) adjusted calf weaning weights. Hemoglobin concentrations were higher (P less than .05) in Se-E-injected supplemented calves at 1 mo of age but not at 5 or 7 mo of age.(ABSTRACT TRUNCATED AT 250 WORDS)

“…In that experiment, calves that received multiple injections of Se had significantly greater ADG than control calves, but in calves given only a single injection it was not significantly different from that of the controls [45]. Similarly, a single intramuscular injection of selenium also had no effect on calves' growth performance, although this kind of administration efficiently prevented deaths from muscular dystrophy [46]. It is worth noting that in the aforementioned papers, animals were supplemented with other forms of selenium than those used in this study.…”

Preliminary study on Se-enriched Lentinula edodes mycelium as a proposal of new feed additive in selenium deficiency

et al. 2020

The presence of selenium in European soil is low and this causes its deficiency in livestock and, in consequence, in humans. This study aimed to obtain Lentinula (L.) edodes mycelium with the maximum content of selenium. This species was used for experiment based on its documented medicinal properties. Calves were fed with selenium-enriched L. edodes mycelium, and serum selenium concentration, average daily weight gains and selected immune parameters were estimated. The selenium-enriched mushroom was found to be safe based on cytotoxicity tests (MTT and LDH tests) and for this reason it was used for further experiments. The mean quantity of selenium in the serum of calves fed with selenium-enriched L. edodes mycelium was significantly higher than that of control calves. Additionally, the calves fed with selenium-enriched L. edodes mycelium had higher body weight gains than those of control calves. White blood cell counts and subpopulations of lymphocytes in the experimental and control calves were within the reference range. The administration of L. edodes enriched with selenium had a beneficial effect on state of health of the calves.

“…This delay could explain the fact that several studies that have explored various ways of selenium supplementation do not show any significant effect of selenium supplementation on growth, weight gain of calves, cows or bulls. The subcutaneous injection [55] or intramuscular [73] selenium has also no effect on growth performance. Similar results are reported in a mineral selenium supplementation (sodium selenite) or organic (selenized yeast) in the cow and calf diets [54,74,75].…”

Selenium in Cattle: A Review

This review article examines the role of selenium (Se) and the effects of Se supplementation especially in the bovine species. Selenium is an important trace element in cattle. Some of its roles include the participation in the antioxidant defense the cattle farms. The nutritional requirements of Se in cattle are estimated at 100 µg/kg DM (dry matter) for beef cattle and at 300 µg/kg DM for dairy cows. The rations high in fermentable carbohydrates, nitrates, sulfates, calcium or hydrogen cyanide negatively influence the organism's use of the selenium contained in the diet. The Se supplementation may reduce the incidence of metritis and ovarian cysts during the postpartum period. The increase in fertility when adding Se is attributed to the reduction of the embryonic death during the first month of gestation. A use of organic Se in feed would provide a better transfer of Se in calves relative to mineral Se supplementation. The addition of Se yeasts in the foodstuffs of cows significantly increases the Se content and the percentage of polyunsaturated fatty acids (PUFA) in milk compared to the addition of sodium selenite. The enzyme 5-iodothyronine deiodinase is a seleno-dependent selenoprotein. It is one of the last proteins to be affected in the event of Se deficiency. This delay in response could explain the fact that several studies did not show the effect of Se supplementation on growth and weight gain of calves. Enrichment of Se in the diet did not significantly affect the slaughter weight and carcass yield of bulls. The impact and results of Se supplementation in cattle depend on physiological stage, Se status of animals, type and content of Se and types of Se administration. Further studies in Se supplementation should investigate the speciation of Se in food and yeasts, as well as understanding their metabolism and absorption. This constitute a path to exploit in order to explain certain different effects of Se.
