Grasses tend to be low in sulfur, although under some circumstances grasses can accumulate high concentrations of sulfate. By estimating the TSC for your herd, based on measured sulfur content of all consumed nutrients, it is possible to evaluate potential hazards. Privacy Statement | Producers that use distillers grains must be aware of t… When the estimated total sulfur concentration (TSC) has been calculated, it can then be compared to the maximum tolerable sulfur concentration. Now you may be thinking that with the importance that sulfur plays in a living organism that must mean that you will need to supplement with a block but that is not always true. Sulfur is an element, and is one of the few in nature that can be found in its pure form instead of in combination with other elements. H2S has the odor of rotten eggs. But fiber and protein content is higher in distillers grains than corn grain. Flatus that is high in sulfur-containing compounds is more odiferous than farts consisting almost exclusively of nitrogen, hydrogen, and carbon dioxide. An estimate of water intake in liters for lactating cows is = 16 + (1.6 X DMI in kg) + (milk production in kg) + (1.2 X minimum daily temperature in degrees C). Sulfate salts have been used in feedlot rations as intake limiting agents to minimize the risk of overfeeding. Routinely use a dry mineral mixture in a walk-through foot box. This is needed for body growth and not just in the muscle area. Use of sulfamethazine in this class of cattle may cause milk residues. Too much sulfur can cause problems with fat loss, though. Cattle producers can mitigate the winter conditions to some extent with proper planning, facility design and good management practices. The National Research Council recommends between 1500 to 2000 ppm of sulfur. Analysis of sulfur intake is required to identify this cause. Now you may be thinking that with the importance that sulfur plays in a living organism that must mean that you will need to supplement with a block but t… We also recognize this problem in range cattle. As mentioned earlier sulfur is a necessary mineral for the well being of your animal. This is a problem of the cerebral cortex that occurs suddenly and leads to blindness, abnormal behavior, severe depression, convulsions, and death. It can be found in every cell of the body and helps to regulate body functions. When dietary sulfur is consumed by ruminants it is reduced to sulfide by ruminal microorganisms. Water purification can be beneficial by removing multiple mineral contaminants. Although severe thiamin deficiency states have not been demonstrated under high sulfur intake conditions, moderate thiamin deficits are possible. Sulfur is an essential component of certain amino acids, vitamins, hormones and sulfated polysaccharides. Sulphur plays an important role in the dietary cation-anion balance of dairy cows. Some Colorado dairies have indeed found production benefits from water purification. Evidence mounts that you should consider sulfur fertilizer for corn, particularly in fields low in organic matter. The adverse effects of excessive sulfur intake can vary. Ethanol byproducts may contain a high concentration of sulfur. Then add the proportionally adjusted sulfur concentrations for all the components. When cattle are transitioning to high sulfate intake conditions, the ruminal sulfide concentration peaks 1 to 3 weeks after the change. According to a paper from the University of Georgia the sulfur requirement is only 0.15% of intake. The cow requires dietary sulfur primarily to provide adequate substrate for maximal ruminal microbial growth. Since it can have a negative effect if their is a high amount of sulfur in your cow’s diet then you may need to provide some extra copper supplementation. Some plants produce a modified WDG (45 to 50 percent dry matter). This is probably due to the formation of copper sulfide and/or the thiomolybdate-copper complex. This will tell you what nutrients it will provide and what it will be lacking in. A formula of 80 percent hydrated lime, 15 percent copper sulfate, and 5 percent flowers of sulfur (acts as an antiseptic) can be used. Use in these classes of calves may cause violative tissue residues to remain beyond the withdrawal time.
