The list above is a list of vitamin e for sheep, minerals for sheep, and b vitamins for sheep. Now im sure you want to know what they do. They’re just called B vitamins. Originally, they were considered a group of eight organic compounds (three each from thiamin, riboflavin, niacin and pantothenic acid)
I hope that this blog post about vitamins for sheep has been helpful. All the information and facts contained in this article are intended to be accurate, but have not been verified by any veterinarian.
vitamins for sheep
It is well known that sheep are exposed to different types of dangers in their environment, including dust and other airborne contaminants, various diseases, and harsh weather conditions causing stress and fatigue. Vitamin E can help these animals to prevent disease and recover faster from the effects of stress.
Good health is important for every animal, but that’s especially true for sheep. They need good nutrition in order to produce enough milk and have a healthy coat. Use these vitamins for sheep and minerals for sheep to help keep your farm healthy.
vitamin e for sheep
Vitamins and minerals play a big role in the health of your sheep. They are designed to give the body specific nutrients that it needs at that time, so they are essential to any animal’s health. Some vitamins and minerals will help you maintain the condition of your sheep while other may help prevent illness.
Vitamin and mineral supplements are given to sheep, goats, and other animals in order to maintain their health and weight. Some animals may need to be supplemented because they are deficient in a particular vitamin or mineral.
b vitamins for sheep
Selenium and vitamin E are essential in sheep diets, and work together to prevent and repair cell damage in the body. Deficiencies of either or both selenium and vitamin E can cause weaner illthrift, reduced wool production, reduced ewe fertility, reduced immune response and white muscle disease. Selenium deficiency is more common in high rainfall areas while vitamn E deficiency occurs when sheep are on dry feed for long periods. Both trace elements can be provided as a supplement.

Why are selenium and vitamin E important in sheep diets?
Selenium and vitamin E are essential in sheep diets. Selenium is a trace element which works with vitamin E to prevent and repair cell damage in the body. Selenium and vitamin E both play a role in immune function and are vital for growth, reproduction, and preventing white muscle disease.
Selenium is found in the soil and taken up by plants. Sheep consume selenium with the plants they eat. Vitamin E is predominantly found in green feed. Both selenium and vitamin E are stored for a short period in the body, mainly in the liver, so a continual dietary supply of these nutrients ensures the best possible production.
What conditions do selenium and/or vitamin E deficiencies cause?
Deficiencies of either or both selenium and vitamin E can cause weaner illthrift, reduced wool production, reduced ewe fertility, reduced immune response and white muscle disease.
In Western Australia, the most common manifestation of deficiency in one or both of these essential nutrients is white muscle disease. If only skeletal muscles are affected, this may result in an illthrift syndrome, but if heart muscle is affected there may be sudden deaths.
Which sheep are most at risk?
In WA, white muscle disease most commonly occurs:
in weaners in the dry months of late summer and autumn (vitamin E deficiency)
in lambs in winter-spring (selenium deficiency) when green feed is abundant, especially if born to selenium-deficient ewes.
Rapidly growing lambs and weaner sheep are most at risk. These young animals have an increased demand for selenium and vitamin E for growth and have had less opportunity than adults to accumulate body reserves of the two.
What causes sheep to become deficient?
Sheep are predisposed to selenium deficiency when grazed on:
pastures grown on selenium-deficient soils (such as acid soils receiving more than 410 millimetres annual rainfall)
lush, rapidly growing pasture
legume-dominant pasture
paddocks that have received heavy or long-term sulphur-containing or superphosphate fertiliser applications.
Vitamin E deficiency is widespread in weaner sheep flocks in WA over the long, dry summer–autumn period when green feed is scarce. Late lambs which have grazed green feed for less than three months are most commonly affected.
Vitamin E deficiency is often associated with feeding weaners for long periods (2–3 months) on dry feed, hay and grain with little or no access to green feed. Vitamin E reserves are depleted more rapidly on a high grain diet.
What are the signs of selenium and/or vitamin E deficiencies?
Signs of deficiency include:
poor growth
stiff gait
arched back
apparent lameness
reluctance to move
sudden deaths.
How can a veterinarian help?
Early diagnosis of disease and treatment are essential to minimise production and stock losses. A veterinarian can help diagnose a selenium or vitamin E deficiency by collecting blood or post-mortem samples for laboratory analysis.
The Department of Primary Industries and Regional Development, Western Australia (DPIRD) provides subsidised veterinary investigations for any livestock disease with high stock losses or similar disease signs to an exotic or reportable disease in order to increase the likelihood of early detection and to provide trading partners with evidence that we are free of particular diseases. For more information about disease investigation subsidies, see the webpage: Surveillance incentives for WA livestock producers.
What are the treatments?
Selenium
For a quick improvement when animals show visible signs of selenium deficiency, a drench or injection containing selenium is the usual treatment. For the correct dose rate and frequency of treatment for each product, read the label and check with your veterinarian.
Note: Take care when giving multiple selenium supplements to avoid overdosing stock. Selenium can be fatal to lambs given an oral dose of one milligram of selenium per kilogram liveweight or an injection of 0.5mg/kg liveweight, so it is important to follow the directions on the product label.
Drench deficient sheep with a vitamin E drench at 2000mg/sheep. This lasts about six weeks. Severely affected sheep may require an additional dose 2–3 weeks after the first dose. If lupinosis is also affecting the sheep, then a 4000mg vitamin E drench is more effective.
Where sheep are too weak to bring into the yard, apply a vitamin E powder to supplementary grain in the paddock to provide 2500–4000mg of vitamin E per sheep.
Affected sheep will improve if they are moved onto a pasture containing green feed, such as a summer-active perennial. The vitamin E in the green feed generally corrects the deficiency within a week.
How can I prevent my sheep from becoming deficient?
Selenium
On properties where there have been previous issues with selenium deficiency, owners may consider:
using a vaccine combined with selenium (effective for 6–8 weeks). Give to pregnant ewes 4–6 weeks before lambing
drenching or injecting lambs with selenium at marking
giving ruminal selenium pellets orally at weaning (effective for 1–3 years depending on the product)
applying selenium fertiliser (prills or chips) to pasture paddocks (effective for three years). If sufficient paddocks have selenium fertiliser applied, this can replace the use of selenium pellets
feeding mineral supplements containing selenium as a supplementary block or lick (note that individual intake of these supplements can be very variable within a flock).
Vitamin E
To prevent vitamin E deficiency, give oral drenches 6–8 weeks after pasture senescence, and then every eight weeks until green feed becomes available. Providing grain treated with vitamin E is an alternative to drenching individual sheep. In summer and autumn, provide access to green fodder such as perennial pastures and shrubs.
Diseases that look like selenium or vitamin E deficiency
Syndrome
Signs of disease
Comments
Weaner illthrift Poor growth and wool production. Low body condition
There are many reasons for illthrift with the most common being a protein or energy deficiency.
Lameness
Non-weight bearing on limbs
Arthritic joints are usually swollen, unlike in white muscle disease. Arthritis may occur on the same or both sides. In white muscle disease lameness usually affects both sides.
Note that lameness can occur with footrot and foot-and-mouth disease, so always have a vet investigate lameness in sheep to determine the cause.
Weakness and sudden death when driven Weakness, un-coordinated walking, paralysis
Sudden death when driving stock may occur with a number of diseases including:
calcium deficiency caused by iceplant poisoning
poisoning by fluoroacetates from gastrolobium plants
anaemia associated with haemonchosis, eperythrozoonosis or cobalt deficiency
annual ryegrass toxicity (ARGT).
Report unusual disease signs
If you see unusual disease signs, abnormal behaviour or unexpected deaths in your stock, call your private veterinarian or the local DPIRD veterinary officer or the Emergency Animal Disease hotline on 1800 675 888.
An adequate diet for optimal growth and production must include water, energy (carbohydrates and fats), proteins, minerals, and vitamins. Under field conditions of particular stress, additional nutrients may be needed. (For detailed nutrient requirements for sheep, refer to the most current Nutrient Requirements of Small Ruminants, published by the National Research Council [ www.nap.edu ].)
Water
A clean, fresh, easily accessible source of water should be available at all times. As a minimum requirement in temperate environments, the usual recommendations are ~1 gal. (3.8 L) of water/day for ewes on dry feed in winter, 1.5 gal./day for ewes nursing lambs, and 0.5 gal./day for finishing lambs. In many range areas, water is the limiting nutrient. For best production, all sheep should have their water availability monitored daily during all weather conditions. However, the cost of supplying water often makes it economical to water range sheep every other day. When soft snow is available, range sheep do not need additional water except when dry feeds such as alfalfa hay and pellets are fed. If the snow is crusted with ice, the crust should be broken to allow access. Still, when possible, sheep should have unlimited access to fresh, clean water.
Energy
Much of a sheep’s diet depends on grass or other forages that can be either sparse or of poor quality, so the provision of adequate dietary energy is important. Poor-quality forage, even in abundance, may not provide sufficient available energy for maintenance and production. The energy requirement of ewes is greatest during the first 8–10 weeks of lactation. Because milk production declines after this period and the lambs have begun foraging, the requirement of the ewe is then reduced to prelambing levels.
The most efficient and accurate way to assess energy adequacy in sheep is to perform and record body condition using an objective 1–5 scoring system, with 1 being extremely thin and 5 being extremely obese. The body condition score is determined by palpating the amount of fat covering on the spinous processes and transverse processes in the lumbar region. Most healthy productive ewes will have a score of 2–3.5. Sheep with a score of 1–2 should be examined and fed to attain a higher score, whereas those with a score >3.5 should be fed less. Dietary changes should be done slowly, and abrupt reduction in total energy intake should always be avoided, particularly in middle to late gestation.
More details on body condition scoring are available from the University of Arkansas Extension, the Western Australia Department of Agriculture, and the Farm Advisory Service of Scotland, among others.
Protein
Good-quality forage and pasture generally provide adequate protein for mature, nongrowing, nonlactating sheep. A minimum of 7% dietary crude protein is needed for maintenance in most sheep. Protein requirements depend on the stage of production (growth, gestation, lactation, etc) and the presence of certain diseases (internal nematode parasites, dental disease, etc). If available forages are unable to supply adequate dietary crude protein, protein supplements, such as oilseed meals (cottonseed meal, soybean meal) or commercially blended supplements should be fed to meet nutrient requirements. Protein should be fed to meet requirements. Excess protein feeding can be beneficial in cases of excessive internal parasite burdens but result in increased production costs and may result in higher incidences of diseases (eg, heat stress, pizzle rot).
Sheep can convert nonprotein nitrogen (such as urea, ammonium phosphate, and biuret) into protein in the rumen but possibly less efficiently than beef cattle. This source of nitrogen can provide at least a part of the necessary supplemental nitrogen in high-energy diets with a nitrogen:sulfur ratio of 10:1. In lamb-finishing diets, the inclusion of alfalfa, approved growth stimulants, and a source of fermentable carbohydrates (eg, ground corn, ground milo) enhance nitrogen utilization.
Minerals
Sheep require the major minerals sodium, chlorine, calcium, phosphorus, magnesium, sulfur, potassium, and trace minerals, including cobalt, copper, iodine, iron, manganese, molybdenum, zinc, and selenium. Trace mineralized salt provides an economical way to prevent deficiencies of sodium, chlorine, iodine, manganese, cobalt, copper, iron, and zinc. Selenium should be included in rations, mineral mixtures, or other supplements in deficient areas. Sheep diets usually contain sufficient potassium, iron, magnesium, sulfur, and manganese. Of the trace minerals, iodine, cobalt, and copper status in ewes are best assessed via analysis of liver biopsy tissue. Zinc adequacy can be assessed from the careful collection of nonhemolyzed blood placed in trace element–free collection tubes. Selenium status is easily assessed by collection of whole, preferably heparinized, blood.
Salt
In the USA, except on certain alkaline areas of the western range and along the seacoast, sheep should be provided with ad lib salt (sodium chloride). Sheep need salt to remain thrifty, make economical gains, lactate, and reproduce. Mature sheep will consume ~0.02 lb (9 g) of salt daily, and lambs half this amount. Range operators commonly provide 0.5–0.75 lb (225–350 g) of salt/ewe/mo. Salt as 0.2%–0.5% of the dietary dry matter is usually adequate.
Calcium and Phosphorus
In plants, generally the leafy parts are relatively high in calcium and low in phosphorus, whereas the reverse is true of the seeds or grain. Legumes, in general, have a higher calcium content than grasses. As grasses mature, phosphorus is transferred to the seed (grain). Furthermore, the phosphorus content of the plant is influenced markedly by the availability of phosphorus in the soil. Therefore, low-quality pasture devoid of legumes and range plants tends to be naturally low in phosphorus, particularly as the forage matures and the seeds fall.
Sheep subsisting on mature, brown, summer forage and winter range sometimes develop a phosphorus deficiency. Sheep kept on such forages or fed low-quality hay with no grain should be provided a phosphorus supplement (ie, defluorinated rock phosphate) added to a salt-trace mineral mixture. Because most forages have a relatively high calcium content, particularly if there is a mixture of legumes, diets usually meet maintenance requirements for this element. However, when corn silage or other feeds from the cereal grains are fed exclusively, ground limestone should be fed daily at the rate of 0.02–0.03 lb (9–14 g).
Sheep seem to be able to tolerate wide calcium:phosphorus ratios as long as their diets contain more calcium than phosphorus. However, an excess of phosphorus may be conducive to development of urinary calculi or osteodystrophy. A calcium:phosphorus ratio of 1.5:1 is appropriate for feedlot lambs. For pregnant ewes, the diet should contain ≥0.18% and, for lactating ewes, ≥0.27%. A content of 0.2%–0.4% calcium is considered adequate, as long as the ratio is maintained between 1:1 and 2:1.
Iodine
Occasionally, the iodine requirements of sheep are not met in the natural diet and thus iodine supplements must be fed. Goitrogenic substances are found in many types of plants (eg, Brassica spp) and interfere with the use of iodine by the thyroid. Regions naturally deficient are found throughout the western USA, in the Great Lakes area, and in other parts of the world. A deficiency of iodine (manifested as goiter in the adult and as lack of wool and/or goiter in lambs) can be prevented by feeding stabilized iodized salt to pregnant ewes. The young of iodine-deficient ewes may be aborted, stillborn, or born with goiters. Diets containing iodine at 0.2%–0.8% ppm are usually sufficient, depending on the animals’ level of production (maintenance/growth, lactation, etc).
Cobalt
Sheep require ~0.1 ppm of cobalt in their diet. Cobalt-deficient soils are found in North America but are relatively rare compared with other parts of the world. Normally, legumes have a higher content than grasses. Because cobalt levels of the feedstuffs are seldom known, a good practice is to feed trace mineralized salt that contains cobalt.
Copper
Pregnant ewes require ~5 mg of copper (Cu) daily, which is the amount provided when the forage contains ≥5 ppm. However, the amount of copper in the diet necessary to prevent copper deficiency is influenced by the intake of other dietary constituents, notably molybdenum (Mo), inorganic sulfate, and iron. High intake of molybdenum in the presence of adequate sulfate increases copper requirements. Because sheep are more susceptible than cattle to copper toxicity, care must be taken to avoid excessive copper intake. Toxicity may be produced in lambs being fed diets with 10–20 ppm of copper, particularly if the Cu:Mo ratio is >10:1. The Cu:Mo ratio should be maintained between 5:1 and 10:1.
Selenium
Selenium is effective in at least partially controlling nutritional muscular dystrophy. Areas east of the Mississippi River and in the northwestern USA appear to be low in selenium. The dietary requirement is ~0.3 ppm. Providing selenium-containing mineral mixture may prevent selenium deficiency if animals are allowed free access. Levels of 7–10 ppm or higher may be toxic.
Zinc
Growing lambs require ~30 ppm of zinc in the diet on a dry-matter basis. The requirement for normal testicular development is somewhat higher. Classic zinc deficiency (parakeratosis) is more common in other small ruminants (goats, llamas, alpacas), but is occasionally encountered in sheep, particularly if fed excessive quantities of dietary calcium (legumes).
Vitamins
Sheep diets usually contain an ample supply of vitamins A (provitamin A), D, and E. Under certain circumstances, however, supplements may be needed. The B vitamins and vitamin K are synthesized by the rumen microorganisms and, under practical conditions, supplements are unnecessary. However, polioencephalomalacia can be seen and is due to aberrations in ruminal thiamine metabolism, secondary to altered ruminal pH and/or microflora content. Vitamin C is synthesized in the tissues of sheep. On diets rich in carotene, such as high-quality pasture or green hays, sheep can store large quantities of vitamin A in the liver, often sufficient to meet their requirements for as long as 6 mo.
Vitamin D2 is derived from sun-cured forage, and vitamin D3 from exposure of the skin to ultraviolet light. When exposure of the skin to sunshine is reduced by prolonged cloudy weather or confinement rearing, and when the vitamin D2 content of the diet is low, the amount supplied may be inadequate. The requirement for vitamin D is increased when the amounts of either calcium or phosphorus in the diet are low or when the ratio between them is wide. Dietary modification should be done slowly and cautiously, to avoid vitamin D toxicity. Fast-growing lambs kept away from direct sunlight or maintained on green forages (high carotene) during the winter months (low irradiation) may show signs of vitamin D deficiency. Normally, sheep on pasture seldom need vitamin D supplements.
The major sources of vitamin E in the natural diet of sheep are green feeds and the germ of seeds. Because vitamin E is poorly stored in the body, a daily intake is needed. When ewes are being fed poor-quality hay or forage, supplemental vitamin E may result in improved production, lamb weaning weights, and colostrum quality. Vitamin E deficiency in young lambs may contribute to nutritional muscular dystrophy if selenium intake is low.

Here is a list of the different types of vitamins and minerals you can give to your sheep. Some supplements can be given alone while others need to be supplemented with other nutrients.
Vitamins are essential to animals, especially ewes. They are an important part of a healthy diet and should be given daily to sheep. Vitamins can help improve growth rates, wool production, and overall health.
As with any animal, sheep need a balanced diet. In addition to a regular supply of forage and water, you should give them minerals (in the form of salt licks or drench-feed) to help maintain their tissues, which are constantly being broken down and rebuilt.
