Abstract AIM: To determine the impact of ingestion of soil on the iodine (I), selenium (Se), copper (Cu) and cobalt (Co; vitamin B12) status of young sheep. METHODS: Twenty young sheep were divided into two groups; one group was fed lucerne pellets, while the other group was fed lucerne pellets plus 100 g soil, for 63 days. At the end of the study the animals were blood-sampled, slaughtered, and the liver removed, and concentrations of I, Cu, vitamin B12 and Se were determined. RESULTS: The… 
Serum analysis revealed that copper, zinc, and iodine values were within reference ranges for domestic ruminants, and the supplementation status of these trace elements was assumed to be adequate, whereas vitamin E levels were low and selenium levels were scarce in several animals, indicating a deficiency of these essential micronutrients.
The prevalence of cobalamin deficiency among vegetarians assessed by serum vitamin B12: a review of literature
Vegans who do not ingest vitamin B12 supplements were found to be at especially high risk, and vegetarians, especially vegans, should give strong consideration to the use of vitamin B 12 supplements to ensure adequateitamin B12 intake.
Exposure to Copper Compromises the Maturational Competency of Porcine Oocytes by Impairing Mitochondrial Function
It is demonstrated that Cu exposure causes abnormalities in the mitochondrial distribution and function, resulting in the increased oxidative stress and levels of reactive oxygen species, DNA damage, and apoptosis, ultimately leading to a decreased porcine oocyte quality.

Effect of soil ingestion on the storage of Se, vitamin B12, Cu, Cd, Fe, Mn, and Zn in the liver of sheep fed lucerne pellets
Abstract The effect of ingesting 100 g/day of two yellow‐brown/yellow‐grey earth soils on the storage of selenium (Se), vitamin B12, copper (Cu), cadmium (Cd), iron (Fe), manganese (Mn), and zinc
An effect of soil ingestion on the utilization of dietary copper by sheep
SUMMARY To test the hypothesis that the ingestion of Mo-rich soils by ruminants might adversely affect Cu metabolism, four groups of initially hypocupraemic ewes were repleted with a Cu-supplemented
The role of a soil × dietary sulphur interaction in the impairment of copper absorption by ingested soil in sheep
Summary Four repletion experiments were carried out to clarify the roles of molybdenum, sulphur and iron in the inhibition of copper absorption by ingested soils. In each experiment, groups of four
The long-term accumulation and depletion of copper in the liver of different breeds of sheep fed diets of differing copper content
SUMMARY Changes in Cu concentration in the livers of adult Scottish Blackface (B), Welsh Mountain (W) and B × W ewes fed diets containing 4, 9, 17 and 29 mg Cu/kg D.M. were measured over a 28-week
Effect of increasing Fe intake on the Fe and Cu content of tissues in grazing sheep.
265 Twelve Romney wetberlambs, average weight 28 kg, were randomly divided into two groups, namely an untreated control and an Fe treated group. All animals were grazed together on a ryegrass/white
The nutrition of ruminants grazing native and improved pastures. V. Effects of stocking rate and soil ingestion on the copper and selenium status of grazing sheep
In experiment 1, sheep ranging in age from newly born to 112 months had greater hepatic copper concentrations at 10 than at 20 sheep/ha but differences in selenium concentration varied between age groups, while in experiment 3, grazing sheep were supplemented with two soils collected from areas which supported sheep with high (HS) and low (LS) blood seenium concentrations.
Ingestion of soil fluorine: Its impact on the fluorine metabolism and status of grazing young sheep
Abstract When young sheep ingested soil fluorine (F) at moderate to high rates (69–184 mg F day−1 for 63 days) the apparent absorption of F ranged from 44 to 53%, while apparent retention of F ranged
Copper oxide needles administered during early pregnancy improve the copper status of ewes and their lambs
Copper deficiency in young lambs may be conveniently and effectively prevented by treating ewes with CuO needles during early pregnancy, and the Cu status of their lambs for 36 days from birth.

A significant linear regression existed between concentration of vitamin B 12 in the liver of a sheep and the logarithm of the concentration in the serum, and there was a linear positive correlation between the rate of depletion of Vitamin B 12 from the liver and the concentration prior to cessation of treatment.
Relationship of dietary selenium to selenium in plasma and milk from dairy cows.
In a 13-wk trial Holstein cows in mid-lactation were fed four diets containing natural selenium alone or supplemented with .1, .2, or .5 mg of inorganic seenium per kilogram of diet, moderate concentrations of dietary selenIUM do not result in toxic amounts of selenarium in milk.
