Symptoms of S Deficiency: There is no reliable soil test to determine Sulphur levels in soils. In most instances, copper deficiency results from the presence of high levels of other minerals (sulfur, molybdenum or iron) in the forage that interfere with copper utilization rather than a simply deficiency of copper in the diet. Boyne, R & Arthur, JR (1986) Effects of molybdenum and iron induced copper deficiency on the viability and function of neutrophils from cattle. High levels of forage sulfur are likely when ammonium sulfate or other fertilizer sources high in sulfur are used. Sulfur deficiency in animals Signs of S deficiency in ruminants include reduced appetite, weight loss, hair loss, weakness, excessive lacrimation, profuse salivation, cloudy eyes, dullness, emaciation, and death (Kincaid, 1988). Polioencephalomalacia in cattle was thought at one time to be caused exclusively by a thiamine deficiency. Magnesium deficiency cannot always be evaluated from urine or blood. Sulphur deficiency prevent grass plants from utilising Nitrogen, which causes the older leaves of the grass plant to turn light green or yellow (N deficiency) and reduces overall yield. Diets for growing and finishing cattle should be formulated to contain 0.15 percent sulfur on a dry matter basis. With maximum diet sulfur levels for cattle suggested at 0.3-0.4%, in the right scenario, adding a supplemental feed could quickly surpass even a well-adjusted cow’s ability to avoid toxicity. Cattle require 1.5g of sulphur per kilogram of dry matter. The likely reasons for this is a reduction in sulfur additions to the crop from atmospheric deposition (there is less S in the air now) and cooler soil temperatures as a result of no-till which slows S mineralization in the soil. 1984). Sulfur Toxicity in Feedlot Cattle1 John J. Wagner, Ph.D. Selenium is thought of as a trace or micromineral in beef cattle diets. Plant Sulfur Needs. The most sensitive and practical test to determine the animal’s magnesium status and predict supplementation value requires measuring urinary creatinine and magnesium. Copper deficiency in cattle. Sulfur Sulfur is present in protein, certain vitamins (thiamin and biotin), enzymes and other compounds. Table 1 shows the S content of common feedstuff for beef cattle rations according to the 1996 Beef National Research Council (NRC). ... amino acids and electrolytes we can increase phosphorus and sulphur levels without impacting on the availability of magnesium and zinc in the product. The maximal tolerated concentration of sulfur for cattle and sheep depends on the type of diet. Cobalt deficiency (cobalt pine) Aetiology. For grazing cattle the main source of sulphur … Numerous field cases of sulphur-induced PEM have also been reported in cattle. Beef cattle only require 0.1 parts per million (ppm) of Se in the total diet (not the mineral supplement). Of interest is the fact that most testing of beef cattle finds normal manganese concentrations in liver, blood, and serum, but in these same matrices, greater than 50%, 75%, and 95%, respectively, of dairy cattle tested are below recommended normal concentrations (unpublished data). This condition would lead to a decline in forage digestibility and ultimately a decrease in animal growth. Copper deficiency in cattle has been well recognized as a widespread potential problem in cattle worldwide. For diets ≥45% forage, the maximal tolerable level of total sulfur is 0.5% dry matter. – Source: DAFWA Since then, sulphur-induced PEM has been experimentally reproduced in sheep and cattle. Sulfur deficiency in cattle is linked to a decrease in ruminal microorganisms and subsequent decrease in rumen function. Phosphorus deficiency in livestock. Story provided by Texas A&M AgriLife Extension and Research. The most sensitive and practical test to determine the animal’s magnesium status and predict supplementation value requires measuring urinary creatinine and magnesium. For diets >85% concentrate, the maximal tolerable level of total sulfur is 0.3% dry matter. Sulphur levels can only be verified through herbage analysis. Further testing indicated these cattle were deficient in magnesium in their diet. The NRC Nutrient Requirements of Beef Cattle recommends 0.15% S to support adequate growth of beef cattle.Sulfur is required for growth and metabolism of many ruminal bacteria, particularly cellulolytic bacteria (Spears et al., 1976).Additionally, S is needed as a component of the S amino acids methionine, cysteine, and cystine as well as the B vitamins thiamine and biotin (). Common causes are not well determined; sodium deficiency, potentially phosphorus deficiency, low-fiber diets implicated Polioencephalomalacia (see Polioencephalomalacia ) Associated with either ruminal destruction of thiamine or with ruminal production of hydrogen sulfide associated with high-sulfur diets; more common in feedlot than dairy cattle In recent years, sulfur (S) deficiency in wheat has become common in many areas of Kansas, particularly in no-till wheat. As pasture matures and the protein content of the grass falls, the intake of sulphur also declines. Gooneratne SR, Olkowski AA, Klemmer RG, Kessler GA, Christensen DA. Copper deficiency may be termed ‘primary’, due to an absolute lack of copper in the diet, or ‘secondary’, due to a relative deficiency of copper caused by the action of antagonistic trace elements (Molybdenum, Iron and Sulfur) and complexes. Magnesium deficiency cannot always be evaluated from urine or blood. While DDGs get most of the rap for high sulfur content in livestock feedstuffs, certain plants can … Manganese deficiency, although not reported often, is identified routinely in dairy cattle when tested. Ranchers need to keep in mind that the wrong quantities of minerals can be dangerous or even deadly to cattle, said experts from the Texas A&M AgriLife Extension Service. Cattle require 1.5g of S/kg of dry matter. cattle. Moran K. PMID: 7445370 [PubMed - indexed for MEDLINE] Publication Types: Letter; MeSH Terms.
