For dairy cows maximum tolerable TSC is recommended to be 0.26% to 0.4% on a dry matter basis. As dairy rations increasingly include salts to modify the dietary anion/cation balance (DCAD), it is important to account for the amount of sulfate that some of these salts contain. This will prevent any deficiency in that area. Enter your email address to subscribe to this blog and receive notifications of new posts by email. Ringworm, an unsightly skin disease, is contagious from animal to animal and can be transmitted between species. While putting sulfur powder has been shown to help in that area there is no, as far as I’m aware, no evidence that the block does that. Dan Gould and Frank Garry. by Heather Smith Thomas. One of the tasks that it does is it is part of the essential amino acids that make up protein. Initially, our sulfur research in herds of animals focused on cattle in the feedlot environment. If there is an excessively high amount of sulfur, such as dried distillers grains, then it would probably be in your best interest to not feed it if you already have a high amount of sulfur in your forages and water. This will allow the proper absorption of the amino acids without causing an over excess of it in the body. A person may be at risk for contracting ringworm when handling affected animals. Ethanol byproducts may contain a high concentration of sulfur. The sulfur occurs as sulfate salts. (1991) used supplemental sulphur to manipulate dietary cation-anion balance of dairy cows receiving corn silage diets. The best way to prevent this from occurring is to have the feedstuffs you will be providing tested. Often a winter problem, ringworm is most frequently seen in young animals. Sulfur is an essential component of certain amino acids, vitamins, hormones and sulfated polysaccharides. Compared with all other farm animals, lactating dairy cows require the greatest amount of water in proportion to their size. However, certain research shows that a diet with small amounts of sulfur may be beneficial in other ways as well. After calcium and phosphorus, it is the third most abundant mineral in the human body. Calcium. Sulfur. In the fall, wet, cold conditions negate the natural insulation value of the hair coat … Since some ground water has high concentrations of sulfate, water purification may be very beneficial for affected dairies. Neither one of these are desirable if you are trying to grow beef. Corn, molasses and sugar beet processing byproducts can be high in sulfur because sulfur-containing acidifying agents may be used in the process. If sulfur intake is large, excessive rumen-generated sulfide can be absorbed in sufficient quantities to result in polio. They can get it from the forages they consume and depending on where you are located they can even get it from the water they drink. Although severe thiamin deficiency states have not been demonstrated under high sulfur intake conditions, moderate thiamin deficits are possible. Characterization of Naturally Occurring Coliform Mastitis, Pulmonary Hypertension and High Altitude Disease in Cattle, Animal and Plant Health Inspection Service (APHIS), Animal Population Health Institute (APHI), Colorado Department of Agriculture State Veterinary Office, College of Veterinary Medicine & Biomedical Sciences, Directions, Lodging, & Pet Boarding Information. Sulphur plays an important role in the dietary cation-anion balance of dairy cows. Sulfur is one macromineral that is important for the health of cattle. If excessive sulfur is consumed, imbalances in ruminal microbial metabolism can occur, and excessive ruminal sulfide accumulates. Because they can get it naturally it can be very easy to overprovide it. You need to weigh the options yourself and decide if it could be something that will work for you. Routinely use a dry mineral mixture in a walk-through foot box. When there is an excess of sulfur it can cause different types of problems. The saliva that they produce while chewing their cud can help negate the high amount of sulfur that they could be consuming. Cattle producers have, over recent years, become well aware that high levels of sulfur molybdenum and other minerals in a cow's diet can affect her ability to absorb copper. Diets for growing and finishing cattle should be formulated to contain 0.15 percent sulfur on a dry matter basis. We also recognize this problem in range cattle. I have always been told the sulfur blocks will help cows shed off the old hair and it seems to work when I've tried them. The ones that love them say that it helps with external parasite control. The disease can also occur as outbreaks of disease that affect several animals in a short time period. Data are presented on the total sulfur content of common feeds used in concentrate mixtures for dairy cows. Tucker et al. It will not provide the other nutrients needed because it is just salt and sulfur. Sulfur is therefore a component of virtually all forages and concentrates. Sulfur is an essential nutrient in cattle diets. Cruciferous forages, such as turnip, rape, and oilseed meals are also rich in sulfur. An Integrated Livestock Management research team, headed by Dr. Dan Gould, professor in Pathology at CSU, has been conducting research on effects of cattle sulfur intake for several years. Sulfur is a necessary mineral that is needed in order to maintain life. Whether this benefit was due entirely to reduced sulfate intake or the removal of several impurities was not specifically evaluated. Recommended dietary sulfur concentrations are 0.20% of diet dry matter for most dairy cattle (NRC 2001). All one need do is consult any of the internet chat groups or visit the local sale barn to hear armchair veterinary advice about the so-called advantages of feeding sulfur salt to livestock.

This is probably due to the formation of copper sulfide and/or the thiomolybdate-copper complex. Now you may be asking “just how much sulfur does my cow need?”. There are ones who love them and swear by them, then there are others who feel they are a waste of money. Determine the concentration of sulfur (S) in the total mixed ration or individual diet ingredients.These are usually reported as % S as DM. 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. If individual feed ingredients or forage components are analyzed, multiply the % as DM for each ingredient by the proportion of the diet it represents. Many distillers grains samples test between 25 and 35 percent protein. This is only so that they animal can properly digest and absorb the protein. Some Colorado dairies have indeed found production benefits from water purification. Copper bioavailability is decreased by high dietary sulfur concentrations. Beef cattle require a number of minerals for optimal growth and reproduction. As mentioned earlier sulfur is a necessary mineral for the well being of your animal. Ringworm in Cattle. Sulfur has been shown to improve the digestion of cellulose such as methionine and cysteine. Dry matter of wet distiller grains (WDG) differs from 25 to 35 percent between plants. Research findings have clarified many aspects of how toxicity occurs, how the cattle respond to excess sulfur intake, and suggest that many dairy operations may have excess sulfur intake as well. Flatus that is high in sulfur-containing compounds is more odiferous than farts consisting almost exclusively of nitrogen, hydrogen, and carbon dioxide. The possibility that dairy cattle may be consuming too much sulfur has not received much attention, and so it is very reasonable that this nutritional issue can be routinely overlooked.
Cows fed diets (including sulfur from water) with 0.40% sulfur also have lower absorption of selenium than cows fed diets with 0.20% sulfur. Calcium is the most abundant mineral in the body, and is an integral part bone and nerve … High water sulfate content is common in this region, but cannot be predicted solely on a geographic basis, requiring water analysis for proper identification. There are four basic steps to the calculation: This assessment is relatively easy, but requires careful attention to the measurements and conversions between various analyses. These projects demonstrate that PEM is only one of the outcomes of excess sulfur intake. Macrominerals include, besides Sulfur, Calcium, Phosphorus, Salt (NaCl), Magnesium, and Potassium. Daily dry matter intake = (1.85% X BW in lbs) + (0.3 X daily milk in lbs). As with everything there are pros and cons to using them. With moderately high levels of sufur intake PEM may not occur, but animal performance can be affected. Sulfur Toxicity in Feedlot Cattle1 John J. Wagner, Ph.D. Excess ruminal sulfide can depress ruminal motility Excess dietary sulfur can also result in secondary metabolic effects due to interference with other nutrients. Since the margin between desirable and maximum level is so small the possibility of sulfur toxicity is very strong. Liters of water intake multiplied by mg S/L = intake of S in mg. Divide by 1000 for intake of sulfur (S) in grams. If your goal is to produce stinky farts, eat foods that contain sulfur compounds, such as cabbage and eggs. In hot weather sulfur intake from water can be elevated due to increases in water consumption. When all else fails you should follow the feeding instructions that is provided on the tag of the sulfur block. Analysis of sulfur intake is required to identify this cause. Despite this mineral’s importance it is very rare that you will need to supplement for it. One of the tasks that it does is it is part of the essential amino acids that make up protein. If there is a high amount of sulfur, like say in your water, then increasing the forage intake of your cattle to an extent can help with that. Such performance problems may attributed to another cause (heat stress, copper deficiency) while the potential role high sulfur has played goes unnoticed. What you want to notice is the overall percentage. The microorganisms will need the inorganic sulfur to create the right amino acids from the NPN. A formula of 80 percent hydrated lime, 15 percent copper sulfate, and 5 percent flowers of sulfur (acts as an antiseptic) can be used. For cattle in general the maximum tolerable sulfur concentration has been estimated at 0.4% on a dry matter basis, and this estimate seems fairly accurate for tolerances in beef cattle in our research. 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… Lower levels of ruminal sulfide can also produce adverse effects. It can be found in every cell of the body and helps to regulate body functions. When crystallized, it is yellow. If a cow eats 1 pound of grain, there's usually only a small percentage left in the manure." Cattle producers can mitigate the winter conditions to some extent with proper planning, facility design and good management practices. Starch content of distillers grains is lower than corn grain. TSC is estimated by adding the % sulfur contributed by the water to the % sulfur contributed by the feed and all additives, all on a DM basis. All Rights Reserved. There is a very real possibility that you are limiting your cows' productivity by effects of high sulfur. It would provide any help and in most cases the risks outweigh any potential, if any, benefits. © Copyright 2019 by College of Veterinary Medicine & Biomedical Sciences
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. This assessment requires estimation of total sulfur concentration (TSC) of dry matter consumed from all sources, including the contribution made by water. Do not use in female dairy cattle 20 months of age or older. More commonly, lower sulfur intakes that do not produce clinical disease can substantially decrease animal performance. As I mentioned earlier sulfur can also interact with the other minerals that are in the diet, such as copper. Privacy Statement |
This is needed for body growth and not just in the muscle area. Website Login
The maximum tolerable dietary concentration of sulfur is 0.4% of the ration on a dry matter basis. Professor and General Manager Southeast Colorado Research Center Colorado State University Lamar, Colorado Introduction: Sulfur is an important component of many functions in the body and is an essential nutrient for beef cattle. The primary use is for external parasite control such as ticks and mites. A deficiency in this can lead to things like diarrhea, light hair coats, broken bones, and infertility. Then add the proportionally adjusted sulfur concentrations for all the components. Some plants produce a modified WDG (45 to 50 percent dry matter). Sulfur is a drug so I don't know how much should be feed. The disease is characterized by blindness, staggering, inability to rise and sometimes, seizures. Disclaimer |
By estimating the TSC for your herd, based on measured sulfur content of all consumed nutrients, it is possible to evaluate potential hazards. Sulfur salt blocks have generated a love/hate relationship among cattlemen. Sulfur is an essential nutrient in cattle diets. It has also been shown to interfere with the metabolism of copper, which brings it’s own problems. Sulfur is used as a feed and mineral supplement to goats and other classes of livestock.
