Chew, M. Frigg, and L. Volker. Cows exposed to 90 minutes of intense sun (centered around noon) maintained serum concentrations of 25-OH vitamin D in the adequate range (Hymoller and Jensen, 2012). Vitamin C is probably the most important water-soluble antioxidant in mammals. Lischer, C.J., U. Koller, H. Geyer, C. Mulling, J. Schulze, and P. Ossent. Campbell, J.R., P.R. Posted by 3 months ago. Data from this experiment do not mean that increasing vitamin C status of cows will reduce the prevalence or severity of mastitis. Figure 1. Barlett, T. Herdt, and P. Gaston. Each organism has different vitamin requirements. Top Answer. (2001) reported that plasma ascorbic acid concentrations in dairy cows were not correlated with SCC; however, the range in SCC was limited (67,000 to 158,000/ml), and cows were only sampled once. Sato, S., H. Hori, and K. Okada. 1.7k comments. Cows need energy for maintenance, activity, pregnancy, milk production and for gaining body condition. Dairy Sci. In general, dairy cows are fed a total mixed ration, which should contain all the nutrients a cow needs in every bite. J. At birth. Figure 2. However, one herd was fed 20,000 IU/day (i.e., NRC requirement) and although the blood average was above 30 ng/ml, several individual cows had concentrations less than 30 ng/ml. As with calves, the vitamin E requirement for breeding cows is not well defined, but has been suggested to range from 200 to 300 IU per kg for pregnant cows (Source Alberta Agriculture and Rural Development). Nutrition is complicated and CONTROVERSIAL. Dairy Sci. Because of price and scarcity, many nutritionists are re-evaluating vitamin supplementation strategies. Ewes. Most concentrates are poor sources of b-carotene. SHEEP. A dietary biotin requirement has not been established for dairy cows (or any other ruminant). This includes breathing and maintaining body temperature. 87:609-619. The only other possibility for getting vitamin D through vegan foods is with the use of irradiated mushrooms. Santos, M.V., F.R. 81:1412-1419. J. Vet. share. Yearlings. From a survey of commercial and university dairy herds, feeding 30,000 to 50,000 IU/day (1.5 to 2.5 X current NRC recommendation) maintained serum 25-OH vitamin D well above 30 ng/ml. Since it contains double bonds, vitamin A can exist in different isomeric forms. New data suggest a role of vitamin D in immune function and more general health responses (Lippolis, 2011) and supplementation rates may need to be higher to see these responses. Modulatory effects of dietary B-carotene on blood and mammary leukocyte function in periparturient dairy cows. 78 (Suppl. The 2001 NRC has the same supplemental vitamin A requirements for all dairy cattle (50 IU/lb BW) and data generally support that. I am not advocating removing all supplemental vitamin A from lactating cow diets; however, feeding no supplemental vitamin A for a month or so likely will have no negative impacts. Effect of dietary thiamin supplementation on milk production by dairy cows. Weiss, W.P., J.S. Directions For Use. Can. The amount of feed a cow eats-and the basic amount of feed a cow needs-is based on their weight. Those two vitamins (or their precursors) must be in the diet, or cows will become clinically deficient. Grummer. I was eating dairy and destroyed my bones. 2004. The decrease in plasma retinol is caused entirely by secretion of retinol into colostrum starting about 7 days before calving because mastectomized cows experienced no decrease in serum retinol at calving (Goff et al., 2002). If the diet is composed of 50% or more of pasture DM, no supplemental vitamin E is needed. Their diet should contain a balance of grass, legumes, protein, grain, silage, antioxidants, vitamins, and minerals as well as a lot of water. Res. Next highest priority is far-off dry cows, followed by lactating cows. The basal diet likely provided no b-carotene. Sci. However, with the widespread application of straw-based dry cows diets (i.e., low b-carotene diets), increased supplemental vitamin A may be warranted (discussed above). Fat Soluble Vitamins . This is probably caused by the data showing relationships between low vitamin D status and increased risk for numerous diseases in humans. Salt is the primary mineral all cattle need," Cole says. Choline supplementation may reduce the risk of ketosis and fatty liver in over-conditioned dry cows, and the use of choline is probably warranted in that situation. Wilkinson. Dairy Sci. Just like people, cows need a complete and balanced diet. Milk yield responses to supplemental choline (either fed in a rumen-protected form or infused post-ruminally) are inconsistent, with about 50% of the studies reporting a positive response and 50% reporting no effect (Donkin, 2002). J. Packington, C.J. Substantial amounts of feed grade vitamin A (retinyl palmitate) can be destroyed during storage and this potential loss should be considered when developing formulating strategies. The results in Table 2 highlight the type of supplementation usually needed in a cow herd. Dairy Sci. Gay. Dairy Sci. Nutrient for health, reproduction, and growth. Dairy Sci. Diets for lactating cows >15 to 30 days in milk should provide an average of about 500 IU/day, and diets for dry cows <265 days of gestation should provide approximately 1000 IU/day. Choline does not fit the definition of a vitamin. Based on current information, the NRC (2001) requirements for vitamin A (approximately 75,000 IU/day for all cows) and vitamin E (500 IU/day for lactating cows and 1000 IU/day for dry cows) are adequate. It is a major component of the skeleton, which also serves as a calcium storage site. Leslie. Liver retinol concentrations in beef heifers and steers fed no supplemental vitamin A and a basal diet void of b-carotene diet (Figure 2) dropped from about 474 mg/kg (dry basis) to 210 mg/ kg over 84 days (Alosilla et al., 2007). Control ME = 25,900 lb, Field trial, 10 farms/trt (lactating Holstein cows), No effect on milk yield. Producers need to monitor mineral consumption regularly to be sure cows are consuming proper amounts. Copyright © 1999-2021 Engormix - All Rights Reserved. Adequate vitamin D can be synthesized by skin cells when they are exposed to enough sunlight. Neither human nor animal have any need for what’s called “vitamin B12.” It’s the same random bacterium and microorganisms used in antibiotics. lining of digestive and reproductive tracts). 84:134-139. Supplemental dietary biotin for prevention of lesions associated with aseptic subclinical laminitis (pododermatitis aseptica diffusa) in primiparous cows. Dairy Sci. At calving. That recommendation is for all classes of dairy cattle. Effect of vitamin B-2 on somatic cell counts in milk of clinical Staphylococcus aureus mastitis. Rodrigues, S.B.M. However, 50 to … Because of major production problems, vitamin A and to a lesser extent vitamin E are in very limited supply and prices have increased markedly. anon189510 June 23, 2011 . Marginal deficiencies of vitamins usually have more subtle and less defined signs. 87:32-37. Diets used in the studies evaluating supplemental vitamin E were largely hay-based for dry cows and silage based for lactating cows. As performance-athlete type metabolisms, they’re quite carefully monitored by their caretakers, and in the toolbox of common treatments for common issues (generic pepto-bismol, aspirin, probiotics, activated charcoal, mineral oil, various CMPK supplements, etc) a vitamin-B shot is … In order to stay healthy, beef cows need a wide variety of food. The take home from this is: Milk contains about 7 mg of retinol/kg of fat or about 0.11 mg/lb of milk (assumed 3.7% fat). These tiny amounts of micro-minerals or trace elements, along with vitamins are … This page describes the Vitamins and Minerals present in milk, and the Effects of Heat Treatments and Light Exposure on the Vitamin and Mineral Content in Milk.A description of the nutritional function of vitamins and minerals is provided on the Nutritional Components in Milk page in the Nutrition Facts section. For example, humans need to get vitamin C from their diets — while dogs can produce all the vitamin C … The National Research Council (NRC 2001) has determined that two specific B vitamins, folic acid and pantothenic acid, are likely to be nutritionally limiting. On a mass basis, that is only about 80 mg/day of supplemental vitamin. Vitamins, especially A and E, are important around calving. Therefore, the current NRC recommendation should be adequate for cows producing 75 lb of milk. These injections are required in a series and need to be administered until the calf has a functioning rumen. At lambing . Babies up to the age of 1 year need 8.5 to 10 micrograms of vitamin D a day. Lambs. 8-10. ed. The common form of supplemental vitamin A is all-trans retinyl palmitate with some retinyl acetate also being used. First off … J. People get their balanced diet by eating a variety of foods with different vitamins and minerals. We dig into the challenges and offer tips to do it right. Prevention . In about 60% of the studies with early-lactation cows, niacin increased or tended to increase milk yield (average response was 6% or 3 to 5 lb/day). As with vitamin E, plasma concentrations of retinol and b-carotene drop markedly starting about 2 weeks prepartum, even when cows are fed diets adequate in supplemental vitamin A (Goff and Stabel, 1990; Weiss et al., 1994). One study suggested that excess vitamin E during the dry period (3X NRC) may actually be detrimental to cow health (Bouwstra et al., 2010). Plant based calcium is best, not from milk! Effects of biotin supplementation on peripartum performance and metabolites of Holstein cows. Why are cows used as meat? The addition of both vitamin E and selenium is more effective than the addition of either alone. Zimmerly, C.A., and W.P. 85:60-67. Table 1. Straw is essentially void of tocopherol, but it often replaces hay which is low in tocopherol. Pelleting and excess heat, humidity and sun exposure during storage will greatly increase losses in activity. Svendsen. Dairy Sci. Calcium is involv… 163:51-60. Injections of riboflavin (2.5 mg/kg of BW) improved neutrophil function and reduced SCC in cows with intramammary infections of Staphylococcus aureus but did not affect cure rates (Sato et al., 1999). So far, there is no evidence to suggest that supplementing above … Effect of therapeutic dietary biotin on the healing of uncomplicated sole ulcers in dairy cattle – a double-blinded controlled study. 44:51-58. J. Wiki User Answered . It’s common practice to give dairy cows Vitamin B and Vitamin E supplements when they suffer an illness or seem unwell. The NRC guidelines should be the starting point when developing a vitamin nutrition program. Butter and butter substitutes including vegan butter alternatives do not need to be fortified 3. Bateman, J. TenHag, J.S. Although vitamins A, D, and E are essential to cows, not much new information is available on those vitamins. For ration formulation purposes, knowing the true requirement for vitamins is not essential. Do cows need vitamin d? Vitamin A is the most important vitamin in cattle nutrition. Beef cows eat roughages, grains, oil-seed, and co-products. Vitamin E supplies have been reduced and prices have increased 3 to 4 times over historic prices, but true shortages have not been reported. Schwab, S.J. Vitamin E requirements vary widely depending on diets, with higher vitamin E required if the diet is high in sulfur-containing amino acids, … Girard, C.L., and J.J. Matte. To minimize calf scours, intake needs to be 30,000 to 45,000 IU per day. J. Vet. Very little, if any, dietary choline (with the exception of rumen-protected supplements) is absorbed from the gut because it is degraded in the rumen. Cows should get at least 20,000 IU per day, and heifers between 10,000 and 20,000 depending on size. Top Answer. Quantity of milk is an important consideration as milk is an important source of vitamin A, higher producing cows requiring more dietary vitamin A. Vitamin A content of milk from different species is illustrated in Table 2-3. The purpose of this paper is to discuss recent (last 10 years) research on vitamin nutrition of dairy cows. Dairy Sci. Press, Washington, D.C. Potzsch, C.J., V.J. Fresh pasture usually contains very high concentrations of vitamin E, and little or no supplemental vitamin E is needed by grazing dairy cows. Amer. Each organism has different vitamin requirements. Instead of flopping down a pre-made and rationed salt and mineral lick, we provide her with individual minerals that she can consume in her own time at her own free will. 86:3953-3962. Prioritizing When Vitamin A Supplies are Limited. J. 1998. Heirman, T.S. Weymour, T.F. all mammals need vitamin D,how they get it is a question I don't know the answer to. She instinctually knows what she needs. In other words, the concentration of vitamin A (IU/lb of DM) does not have to be increased for high producing cows). This is equivalent to approximately 500 and 1000 IU/day for lactating and dry cows. The liver and kidney of the cow can synthesize vitamin C. Ruminal and intestinal bacteria synthesize most, if not … Dairy cows have an enormous … 1):71-90. Presented at the Tri-State Dairy Nutrition Conference, April 2018. They have low intakes of basal b-carotene, several studies have shown increased retained placenta and mastitis when dry cows are not fed adequate vitamin A, and the newborn calf will need retinol-rich colostrum since calves are born with almost no circulating retinol. Rumen-protected choline: potential for improving health and production in dairy cows. J. 86:2106-2112. As a general rule of thumb, cattle should receive at least 15 to 20 international units (IU) of vitamin D3 daily per pound of bodyweight (1 IU of vitamin D3 = 25 ng). The NRC recommendation is based on several assumptions: 1. Corn silage is a poor source of b-carotene and usually has about 50% of the concentration found in haycrop silages. Cows and Heifers. Liver depletions rates have not been determined in lactating cows fed typical diets, but based on beef data, liver retinol will remain in the adequate range for several weeks to a few months when all supplemental vitamin A is removed from the diet. Vitamins like minerals are essential nutrients for cattle. 1 2 3. (2003) observed a quadratic effect of B-vitamin supplementation on feed intake and milk production by dairy cows. We recently conducted an experiment to examine changes in ascorbic acid status following an intramammary challenge with E. coli (Weiss et al., 2004). Vitamin A is vital in cow rations in the last trimester through the first couple of months of lactation. However (and this is important), there are no data showing that supplementation of vitamin A at rates above the current NRC requirement has any positive effect on mammary gland health or reproductive efficiency; a possible exception is increased ovulation rate when cows are superovulated (Shaw et al., 1995). We know very little regarding vitamin flow out of the rumen and even less regarding efficiency of absorption of vitamins from the gastro-intestinal tract of cows. Excessive supplementation also may incur a cost by having negative effects on health and productivity (true toxicity can also occur, but generally vitamin intakes have to be extremely high). 2002. Dairy Sci. The most severe situation (seldom observed in the U.S. dairy herd) is a clinical deficiency. In two large field studies (Erskine et al., 1997; LeBlanc et al., 2002), injected vitamin E (3000 IU at either 14 or 7 d prepartum) reduced prevalence of retained fetal membranes. Research is extremely limited on the effects of supplementing B-vitamins other than biotin and niacin to dairy cows. Seymour, and N.S. Hedges, J., R.W. What is unusual is that plasma retinol concentration is a very poor indicator of vitamin A status or vitamin A intake. Bertics, W.M. In most situations rumen bacteria supply the animal with an adequate source of B vitamins as well as vitamin K. Vitamin A requirements for dry pregnant cows are based on days pregnant and range from 5,576 to 8,244 IU per kg (2,535 to 3,747 IU per lb) feed. Vitamins A and D: Very little data are available showing any positive effects at rates higher than NRC (approximately 70,000 IU/day for A and 20,000 IU/day for D), but because vitamin A and D are inexpensive and because of some possible (but not highly likely) benefits, oversupplementation is advisable. At a consumption rate of 75 grams (2-1/2 ounces), the cow receives 33,750 IU of vitamin A and 3,300 IU of vitamin D daily, matching her requirement. In two other experiments, cows fed thiamin at 300 mg/day had similar milk yields as control cows. 2004. 2001. The current requirement for supplemental vitamin E is about 0.3 IU/lb of BW for a lactating cow and 0.7 IU/lb BW for a dry cow. In a study with lower-producing cows (<45 lb/d), biotin supplementation had no effect. The effect of ascorbic acid and L-histidine therapy on acute mammary inflammation in dairy cattle. The actual requirement of vitamin A … A bigger problem than increased cost is limited supply. • the absolute minimum amount of fibre is 30% Neutral Detergent Fibre (NDF) or 17% Crude. Washburn, and J.H. Increased supplementation of vitamins will cost from < 1 cent/day per cow (vitamin A and D) to 30 or 40 cents/day (rumen-protected choline). If recent data with ruminants are lacking, the vitamin is not discussed. J. 83:338-344. Cow milk is designed for cows, not humans! Unthriftiness (reduced growth rate, milk production, or fertility) and increased prevalence of infectious diseases can be observed when animals absorb inadequate amounts of vitamins. Energy can be supplied in a number of ways. McDowell, R. McMahon, L. Badinga, F.G. Martin, J.F. 4-5. At weaning. Effect of vitamin E supplementation in diets with a low concentration of selenium on mammary gland health of dairy cows. J. Britt. "Current research indicates that stored feeds do not contain adequate amounts of Vitamin E to meet the animal requirements," says Barry Yaremcio, beef … Any opinions, findings, conclusions, or recommendations expressed in this publication are those of the author(s) and do not necessarily reflect the view of the U.S. Department of Agriculture. When fed deficient diets, animals mobilize retinol from the liver and plasma levels are maintained until liver concentration drops below about 30 mg/kg (clinical deficient state). Hepatic retinol concentrations less than 30 mg/kg (dry basis; all liver concentrations in this paper are on a mg/ kg dry weight basis) is considered indicative of a vitamin A deficiency and values less than about 100 mg/kg are considered suboptimal. J. Dairy Sci. Trower, B.D. If you eat a steak, you’re giving your body nutrients like vitamin B12, zinc, iron and selenium, just to name a few. Mineral elements and vitamins are required in small amounts but a deficiency could produce significant reductions in growth and reproduction in otherwise adequately nourished beef cows and calves. they have lots of vitamin. This suggests that feeding 20,000 IU/day may not be adequate; however, data showing improved clinical or production responses with additional vitamin D supplementation are lacking. With a typical NEm value of 98 Mcal/cwt, the deficiency found with grass hay #4 (Table 2) can … 4-5. Higher forage diets are also typically higher in b-carotene which can be converted into vitamin A by the cow. 4-6. Cows during the last 14 days of gestation and the first two to four weeks of lactation may benefit from consuming 2000 to 4000 IU of vitamin E/day. Shaver, R.D., and M.A. The amount of vitamin D synthesized depends on intensity of the sunlight which depends on season (summer >> winter) and time of day (noon > morning or evening), cloud cover, and duration of exposure. Vet. If fed the same diet, depletion will occur more rapidly in a dairy cow than a beef animal because of secretion of retinol in milk; however, typical dairy cow diets contain more b-carotene than feedlot diets. Mushrooms can produce vitamin D when exposed to sunlight 4. Based on current information, the NRC (2001) requirements for vitamin A (approximately 75,000 IU/day for all cows) and vitamin E (500 IU/day for lactating cows and 1000 IU/day for dry cows) are adequate. Introduce cattle onto good quality feed slowly. In another review of niacin (Girard, 1998), experiments were classified based on stage of lactation (Table 4). Without reliable data regarding vitamin supply from basal diets (i.e., control diets), actual requirements cannot be determined. It is the only one that normally must be added to cattle diets. 77:1408-1421. See Answer. 8-10. How much vitamin A do cattle need? I think of a “good” overwintering cow mineral as one that helps meet the mineral and vitamin requirements of the early- to mid-gestating beef cow by complementing those nutrients found in forages and feedstuffs fed until the calving season. 1 Vitamin A is a fat-soluble vitamin that can be found in the fat portions of animals and is quite abundant in milk fat. A separate requirement for β-carotene has not been established. J. Amer. When an animal absorbs an inadequate quantity of a particular vitamin, various responses are observed depending on the vitamin and the degree and duration of deficiency. Vitamin C also is not considered a vitamin for dairy cows because the cow can synthesize ascorbic acid. 61(5):569-571. Weiss, W.P., J.S. In addition, most cows are probably in excellent vitamin A status (large liver stores of retinol), and it is acceptable for the cow to mobilize that as long as liver concentrations of retinol stay above 30 mg/kg and ideally above about 100 mg/kg. Serum 25(OH)D of yearling heifers receiving 11,000 to 12,000 IU of vitamin D 3 /d was near that of cows at 76±15ng/mL. Weiss. It is required in gram quantities (not milligram or microgram quantities), and it is synthesized by the cow. The effect of prepartum injection of vitamin E on health in transition dairy cows. Tristate Dairy Nutr. 47:599-608. The water-soluble ones include the B vitamins and vitamin C. Fat-soluble vitamins include A, D, E and K. The liver and kidney of the cow can synthesize vitamin C. Ruminal and intestinal bacteria synthesize most, if not all, of the B-vitamins and vitamin K, and under most situations, cows probably do not need to consume those vitamins to prevent clinical deficiency. These include the water-soluble and fat-soluble vitamins. Current data support the 2001 NRC requirement for dry and lactating cows. 80:1728-1737. Duffield, K.E. Hay-based diets will need more supplemental vitamin A than silage based diets. The current NRC (2001) requirement for supplemental vitamin A is 50 IU/lb of body weight (BW) or about 70,000 to 77,000 IU/day for an adult cow. 2001. 8-10. Effects of biotin supplementation on performance and claw lesions on a commercial dairy farm. A longitudinal field trial of the effect of biotin on lameness in dairy cows. Calcium is an important mineral for beef cattle, both in terms of the relative requirement and the diversity of functions in the body. The use of supplemental niacin in herds that feed a single diet to all cows is unlikely to have a positive return on investment. Benefits of supplementing vitamins in excess of NRC recommendations may include improved health, increased production, and improved reproduction. J. Although vitamins A, D, and E are essential to cows, not much new information is available on those vitamins. Either the vitamin must be in the diet (dietary essential) or be synthesized by microorganisms in the digestive system and absorbed by the host animal. Although the response varied among experiments, all studies reported reduced prevalence of specific lesions or clinical lameness when biotin was supplemented. J. "But while the rumen provides for much of the cows B vitamin requirements, many circumstances indicate a need for supplementation. The last priority is lactating cows. Girard, C.L. Do cows need vitamin d? Finishing lambs. Milk yield by multiparous cows increased linearly as supplemental folic acid was increased from 0 to 1.2 or 2.4 g/day, but no response was observed with first lactation animals (Girard and Matte, 1998). However since most of the experiments evaluating responses to vitamin A consisted of corn silage, this effect is already incorporated into requirements. Peripartum serum vitamin E, retinol, and beta-carotene in dairy cattle and their associations with disease. No requirement for dairy cows has been established for niacin, but niacin is involved in most energy-yielding pathways and for amino acid and fatty acid synthesis and therefore is important for milk production. The food you provide will influence the taste, fat, and quantity of the milk produced and will play a major role in the length of the lactation period. Vitamin A and the precursors, carotenoids, are rapidly destroyed by oxygen, heat, light and acids. The addition of vitamin A to skim and partially skimmed (1% or 2%) milk is a legal requirement under Health Canada’s Food and Drugs Act.The amounts range from 1,200 to 1,500 IU or 1,200 to 2,500 IU per 852 mL, depending on the type of milk. The diet is approximately 60% forage,2. 2001. When the amount of supplemental B-vitamins was doubled, intake and milk production were similar to control cows (i.e., lower than the 1-x supplementation treatment). Cows in early lactation (0 to 30d in milk) also had lower serum 25(OH)D than did mid- to late-lactation cows (57±17 vs. 71±20ng/mL, respectively). Johnson. B vitamins (biotin, folate, niacin, pantothenic acid, riboflavin, thiamine, vitamin B-6, and vitamin B-12) Although the word “requirement” was used liberally in the above discussion, that word implies a much greater knowledge base regarding vitamin nutrition than is actually available. 1995. Wiki User Answered . Little benefit would be expected when mid- and late-lactation cows are fed supplemental biotin. 87:2535-2545. Blowey, A.J. In studies with higher-producing cows (>75 lb/day), supplementation increased milk production 2 to 7 lb/day in four studies (average response = 3.4 lb/day), but no response was observed in one study. It is not known whether additional vitamin A during the prefresh period will prevent the decrease in plasma vitamin A or whether the decrease is even a problem. Because of low expected intakes of basal b-carotene and the high requirement of vitamin A for colostrum synthesis, prefresh cows should be fed at NRC rates at the expense of other cows. 1998. 3-4. This equates to about 500 IU/day for lactating cows and 1000 IU/ day for dry cows (Table 1). No data are available refuting current recommended (NRC) supplementation rates for vitamins A and D. Because of … J. Vitamin E has a role in the immune system. Less is known about biotin concentrations in forages. Hoblet, W.P. 2003. However, if the straw replaced hay silage, intake of basal tocopherol could decrease by 100 to 150 IU/day. Effect of retinal palmitate on superovulation rate and embryo quality in superovulated cattle. 2003. Indeed, one study reported a significant decrease in milk yield when early lactation cows were supplemented with about 550,000 IU/day. It is necessary for bone development, sight, and maintenance of healthy epithelial tissues (i.e. Med. In three experiments, Shaver et al. Responses to folic acid may be caused by increased methionine status. Barros, and L.F.L. Good animal husbandry requires that diets be formulated to provide enough vitamins to prevent clinical deficiencies. A recent study evaluated feeding 2X NRC (95 IU/lb BW) and reported some small increases in various measures of immune function, but no effects on production and clinical responses (e.g., mastitis) were measured (Jin et al., 2014). 81:189-200. However, all cows should be fed supplemental fat-soluble vitamins but not all cows need to be supplemented with water soluble vitamins. From these macro-, trace- mineral and vitamin parameters, our good overwintering cow mineral needs one more thing — “good” and consistent feed intake. Vitamin B12 is metabolically related to other essential nutrients, such as choline, methionine and folic acid. 1998. Green. In all cases, observing cows, how they are eating, and what they look like will be the most valuable management. Subsequently, the young calf receives the vitamins from its mother. Therefore, a diet with 50% forage may need about 17% more vitamin A (~84,000 IU/day) than recommended by NRC (2001); however, a cow fed an 80% forage diet may need only 0.65 X NRC requirements (~47,000 IU/day). Dairy Sci. Since the NRC was published, two additional studies were published, and one (Drackley et al., 1998) reported an increase in milk yield, and one (Minor et al., 1998) reported no effect.
