Have "escape" pastures, the ability to exit from alfalfa if conditions for grazing are very poor. Also be careful not to damage your alfalfa stand. Sedivec said another potential issue with grazing in the fall and winter is the effect of overgrazing on alfalfa stands. Dr. Rick Rasby, Professor of Animal Science Animal Science, University of Nebraska–Lincoln, Lincoln, NE. Never move cattle in the morning. Management of cattle on alfalfa pasture is a dynamic art and must be done with an appreciation of the factors that can cause fluctuation in the intake of alfalfa. Environmental factors that interrupt regular grazing bouts on alfalfa pasture such as storms, exceptionally hot weather or biting flies can alter intake patterns and increase the risk of bloat. If an outbreak of frothy bloat occurs all cattle on that pasture should be removed immediately and put onto a high fibre diet (hay or straw), and any cows showing bloating signs treated with an anti-foaming agent. using a series of old wooden self-feeders. Pasture (frothy) bloat can occur in animals grazing wheat pasture or lush legumes (alfalfa, ladino, white clover) or being fed green-chopped legumes. For additional information, please see "Bloat in Beef Cattle". It is likely that the risk of bloat in frozen alfalfa decreases with time as proteins complex with carbohydrate in a manner similar to that achieved with wilting or drying. Keep dry hay out where cattle pass by it daily. However, as many a dairy farmer can attest to, cattle can still bloat on alfalfa hay, and long term frozen alfalfa should be considered bloat reduced, not bloat safe. Alfalfa is recognized as one of the most nutritious forages available and is widely used as conserved forage (ex, hay, silage) in the diets of beef and dairy cattle. Pasture (frothy) bloat can occur in animals grazing wheat pasture or lush legumes (alfalfa, ladino, white clover) or being fed green-chopped legumes. Cases have been reported from grazing of red clover, but its risk of causing bloat is much lower than that of white clover. Even when sheep have been eating just hay, they can bloat due to … Since bloat is not caused by any microbe, there is no vaccine for prevention. Feed Rumensin. Alfalfa (green or fed as hay) is good feed for calves or young cattle, lactating cows and pregnant cows in late gestation. However, as these forages become depleted, the risk of bloat increases and such a scenario is often responsible for bloat outbreaks two to three days after animals have been moved to a new pasture. Grazing alfalfa can be toxic to cattle, sheep and other ruminant animals, as live alfalfa plants with moisture on the leaves will cause bloat (a build-up of gas) in all ruminant animals. It likely stems from the fact that alfalfa can cause bloat in cattle due to the layout of their intestinal tract. Feedlot (dry) bloat usually refers to bloat in cattle fed high-grain rations that may or may not contain legume forage. Preventing bloat is desirable not only to reduce deaths but also to reduce the negative effect of bloat on cattle per-formance. It is discouraging to discover that a newly purchased lot of alfalfa hay causes bloat, especially if it is the only forage available. Don't clip a grass-legume pasture and then immediately turn cattle out onto it. Older cattle eat more per unit body weight than younger cattle. Don't clip a grass-legume pasture and then immediately turn cattle out onto it. Alfasure liquid bloat product is 100% effective in preventing bloat and can be used during risk periods. Also, although cows can feed on alfalfa, excess feed can be detrimental to health. Animals with frothy bloat have a stable gas-liquid mix at the top of the rumen that traps feed and prevents gas release. Cattle can bloat from Red clover but with any legume cattle should be eased into it so they get accustomed to it.Blending some grass hay with red clover would make a lot more sense then mixing dry and wet red clover.Mixing grass in with red clover for pasture or hay is a good idea to help control bloat. In primary ruminal tympany, or frothy bloat, the cause is entrapment of the normal gases of fermentation in a stable foam. This will reduce the bloat problem in all animals that will eat. Agronomic strategies such as the co-cropping of bloat safe legumes (ex, sainfoin, birdsfoot trefoil) with alfalfa and wilting of the alfalfa prior to consumption are being explored for their ability to provide additional bloat protection. High stocking densities increase competition for the alfalfa and reduce the likelihood of any one animal selectively grazing only the top portion of the plant. Although there are few experiments to prove the concept, most experienced producers would agree that cattle must learn to graze alfalfa. The main causes of bloat are an inherited tendency for bloat, certain proteins in forage (particularly in legumes), the coarseness of the roughage and the type of rumen microbial population. However, I know of two extreme cases of grain bloat where cattle in Saskatchewan were fed high-grain diets in self-feeders and a few bloated animals died. Bloat usually occurs an hour to one and a half hours after a major grazing bout. Also, maintain access to dry hay or corn stalks while grazing alfalfa to help reduce bloat. The Animal Alfalfa is one of the few forages that is capable of sustaining levels of production that are comparable to those achieved in the feedlot. Winter wheat can also cause bloat when it is lush in the spring. Ruminant livestock grazing lush pastures of alfalfa, clovers and small grains are prone to a condition called “frothy bloat.” Rapid digestion of forage containing highly-soluble proteins results in a stable foam which prevents rumen gases from being expelled by normal eructation (belching). Select against it. It is likely that the risk of bloat in frozen alfalfa decreases with time as proteins complex with carbohydrate in a manner similar to that achieved with wilting or drying. Pasture (frothy) bloat can occur in animals grazing wheat pasture or lush legumes (alfalfa, ladino, white clover) or being fed green-chopped legumes. In the first case, the producer backgrounded a couple of hundred five-cwt steers to 900 lbs. The cattle (and equines) have been getting somewhat limited hay (excellent coastal) because our hay buggy is broke and we had to pull mass quantities of hay by hand three times a day from our round bales and throw it over the fence to the livestock (after carrying it 50 yards). Another tactic is to let the forage become more mature so it is not so lush, and graze it during the frost-free period. The condition is called bloat. Dry matter intake, as a percent of body weight, can vary from 1.5 percent on straw to 2.75 percent on quality alfalfa hay. I've never heard of acidosis from alfalfa hay, but it can cause bloat, which can also kill deer. Provide grass hay or grain for the first week or two of grazing alfalfa. It often occurs secondary to … Alfalfa varieties that have a slower digestion rate are being developed to lower the bloating risk in cattle, however early research into these varieties has shown mixed results in their ability to reduce rates of bloating iii. If water source is controlled it works well. Pasture (frothy) bloat can occur in animals grazing wheat pasture or lush legumes (alfalfa, ladino, white clover) or being fed green-chopped legumes. In cattle, micro-organisms in their rumen, or paunch, produce gas as they digest forages. It seldom occurs on grasses, (or pastures with at least 50% grass), coarser pastures, or hay. Under these conditions, ... information regarding feedlot bloat has included finely ground milo and loose alfalfa hay fed in separate bunks, or finely chopped alfalfa hay … Once introduced, every effort should be made to maintain the herd on alfalfa pasture. It likely stems from the fact that alfalfa can cause bloat in cattle due to the layout of their intestinal tract.

In cattle, micro-organisms in their rumen, or paunch, produce gas as they digest forages. As myths go, the idea that alfalfa contributes to bloat in horses is inflated. Alfalfa is growing rapidly and high risk. Bloat can occur after as little as 15 minutes to 1 hour after they are turned out to a bloat- producing pasture.
