"Reshmabhai Vanabhai Kodarvi of district Banaskantha treat frothy bloaat in cattle with the help of bhootkola vine & water. Treatment is done by drenching the animal the crushed tuber of "bhootkola" vine with water. The tuber is pounded well and mixed with 500 g water. The solution is then filtered and 250 g of it is drenched to the animal immediately and another 250 g after half an hour. This remedy removes gas. The abdomen becomes normal and bloat gets cured." |

| Disease Symptoms / Clinical Signs |
In primary pasture bloat, the rumen becomes obviously distended suddenly, and the left flank may be so distended that the contour of the paralumbar fossa protrudes above the vertebral column; the entire abdomen is enlarged. As the bloat progresses, the skin over the left flank becomes progressively more taut and, in severe cases, cannot be “tented.” Dyspnea and grunting are marked and are accompanied by mouth breathing, protrusion of the tongue, extension of the head, and frequent urination. Rumen motility does not decrease until bloat is severe. If the tympany continues to worsen, the animal will collapse and die. Death may occur within 1 hr after grazing began but is more common ~3–4 hr after onset of clinical signs. In a group of affected cattle, there are usually several with clinical bloat and some with mild to moderate abdominal distention. In secondary bloat, the excess gas is usually free on top of the solid and fluid ruminal contents, although frothy bloat may be seen in vagal indigestion when there is increased ruminal activity. Secondary bloat is seen sporadically. There is tympanic resonance over the dorsal abdomen left of the midline. Free gas produces a higher pitched ping on percussion than frothy bloat. The distention of the rumen can be detected on rectal examination. In free-gas bloat, the passage of a stomach tube or trocarization releases large quantities of gas and alleviates distention. |
| Disease Description |
Bloat is simply the build up of gas in the rumen. This gas is produced as part of the normal process of digestion, and is normally lost by belching (eructation). Bloat occurs when this loss of gas is prevented. There are two sorts of bloat. The least common type is gassy bloat, which occurs when the gullet is obstructed (often by foreign objects such as potatoes) or when the animal can’t burp (such as with milk fever or tetanus). The second type of bloat is frothy bloat, which happens as the result of a stable foam developing on top of the rumen liquid, which blocks the release of the gas. This is by far the most common form of bloat, and unlike gassy bloat, it is highly seasonal with peaks in the spring and autumn. This is because the foam is formed by breakdown products from rapidly growing forages (particularly legumes such as clover and alfalfa). These increase the viscosity (stickiness) of the rumen fluid and prevent the small bubbles of gas formed by rumen fermentation |
| Disease Control |
The ultimate aim in control is development of a pasture that permits high production, while keeping incidence of bloat low. The use of pastures of clover
and grasses in equal amounts comes closest to achieving this goal. Bloat potential varies between cultivars of alfalfa, and low-risk LIRD (low initial rate of digestion)
cultivars are available commercially. The addition of legumes with high condensed tannins to the pasture seeding mix (10% sainfoin) can reduce the risk of bloat where
there is strip grazing, as can the feeding of sainfoin pellets. |
| Disease Prevention |
Prevention of pasture bloat can be difficult. Management practices used to reduce the risk of bloat include feeding hay, particularly orchard grass, before turning cattle on pasture, maintaining grass dominance in the sward, or using strip grazing to restrict intake, with movement of animals to a new strip in the afternoon, not the early morning. Hay must constitute at least one-third of the diet to effectively reduce risk of bloat. Feeding hay or strip grazing may be reliable when the pasture is only moderately dangerous, but these methods are less reliable when the pasture is in the pre-bloom stage and the bloat potential is high. Mature pastures are less likely to cause bloat than immature or rapidly growing pastures. To prevent feedlot bloat, rations should contain ≥10–15% cut or chopped roughage mixed into the complete feed. Preferably, the roughage should be a cereal, grain straw, grass hay, or equivalent. Grains should be rolled or cracked, not finely ground. Pelleted rations made from finely ground grain should be avoided. |
| Precautions |
It is better to understand the causative & predisposing factors and try to control and prevent the occurrence of blot. Regarding the use of herbal plants, understand the type of plant, parts to be used, preparation, storage, formulation, dosage, mode of use by consulting a professional before use. |
| Procedure of Use |
Natvarsinh Jhala uses the traditional fumigation method to cure bloat. He grinds 50 grams of turmeric (Curcuma longa) and mixes it with about 30 grams of salt. He then places hot coals in a vessel and sprinkles the mixture over the burning coals. He puts the hot vessel right under the nose of the animal. The animal inhales the smoke and its bloat is reduced. |
| Etiology Causative Agent |
The cause is entrapment of the normal gases of fermentation in a stable foam. Coalescence of the small gas bubbles is inhibited, and intraruminal pressure increases because eructation cannot occur. |
| Global Context |
Blot condition in livestock animals is spread worldwide. The condition is more common in non-descriptive cattle than dairy cattle. |
| Lesson Implication |
Necropsy findings are characteristic. Congestion and hemorrhage of the lymph nodes of the head and neck, epicardium, and upper respiratory tract are marked. The lungs are compressed, and intrabronchial hemorrhage may be present. The cervical esophagus is congested and hemorrhagic, but the thoracic portion of the esophagus is pale and blanched—the demarcation known as the “bloat line” of the esophagus. The rumen is distended, but the contents usually are much less frothy than before death. The liver is pale because of expulsion of blood from the organ. |
| Other Medications / Treatments |
An ideal therapy of blot condition would be to do rumenotomy as well as eliminate the causative agent and take care of predisposing causes. |
