Milk fever is an example of how complex mineral interactions and imbalances can cause metabolic issues, particularly in lactating animals with increased requirements. MILK FEVER TREATMENT PROTOCOLS Milk fever is due to low blood calcium in cows. Three phases have been described.

Stage I milk fever often goes unobserved because of its short duration (< 1 hour). Such cows may show symptoms of From my own experience first choice of drug is calcium borogluconate 300-450 ml administered intravenously, slowly over a period of 30-45 minutes. Rapid administration of calcium will cause cardiac fibrillation for which antidote is magnesium sulphate intravenous.In case the animal has responded to intravenous with partial injection (say half of the dose), I usually stop the intravenous injection and the balance injection I give sub-cutaneous. This generally involves close attention to mineral and fiber levels in the diet prior to calving, as well as improving cow comfort to eliminate other problems that may interfere with appetite and so trigger hypocalcemia. It occurs following parturition, at onset of lactation, when demand for calcium for colostrum and milk production exceeds the body's ability to mobilize calcium. Signs observed during this stage include loss of appetite, excitability, nervousness, hypersensitivity, weakness, weight shifting, and shuffling of the hind feet.The clinical signs of stage II milk fever can last from 1 to 12 hours. IndianCattle is platform supported by Bombay Gowrakshak Trust from Mumbai. The use of an anionic diet is appropriate when high calcium forages are fed at relatively high levels during the close- up dry period. Cattle milk Fever should be regarded as emergency and treatment must be started at the earliest. Forms of Milk Fever Typical milk fever. Stage 1: Cows are mobile but show signs of hypersensitivity and excitability such as restlessness, tremors, ear twitching, head bobbing and mild Stage 2: Cows can no longer stand and present in sternal recumbency. Usually, several cows are involved. Some of the anionic salts are very unpalatable which can depress intakes significantly in conventional feeding programs. There are reports that immediately after intravenous injection of calcium the serum calcium levels may still be lower, but the injection stimulates the process of mobilization of calcium. Milk fever most often affects mature cows. In the first phase, muscle twitching is common.

Reduced dry matter intakes as a result of feeding anionic salts can lead to the development of other metabolic disorders.Much of the success with anionic salts has been in herds feeding a total mixed ration. In cows where colostrum synthesis has started before calving and udder is full of milk. This website aims to provide a platform for sharing information on improvement in agricultural and cattle breeding techniques, veterinary science, artificial insemination, modern dairy farming techniques. However, the accuracy or completeness of these sources cannot be guaranteed by the authors. Checking urine pH can help producers and veterinarians monitor the effectiveness of an anionic ration.Feeding a combination of different anionic salts is necessary for achieving the desired DCAB, Table 5. The most commonly fed salts are ammonium sulfate, calcium sulfate, magnesium sulfate, ammonium chloride, calcium chloride, and magnesium chloride.
Milk fever, postparturient hypocalcemia, or parturient paresis is a disease, primarily in dairy cattle but also seen in beef cattle and non-bovine domesticated animals, characterized by reduced blood calcium levels (hypocalcemia).

In case the animal responded well to the calcium borogluconate but there is a relapse after 12 to 24 hours in that case also combination should be preferred. Twelve hours after treatment, all calcium administered, whether by the intravenous or subcutaneous route, has been eliminated from the body. An acute form affecting cows usually within a few days after parturition, but it sometimes occurs in late lactation or the dry period. The subcutaneous injection will ensure longer calcium absorption in the blood. In particular, ammonium salts may result in more intake and palatability problems, especially when a silage based ration is not being fed.

AST levels over 200 IU/L flag a guarded prognosis and levels over 500 IU/L can indicate severe muscle damage.Another method of preventing and controlling milk fever is balancing dry cow rations for anions (negatively charged molecules) and cations (positively charged molecules). Serum calcium levels must be corrected as soon as possible by administering intravenous calcium gluconate slowly over 10-20 minutes. When calcium is given intravenous most of it is excreted in the urine. During cold weather the solution should be warmed to body temperature. This leads to the most common sign of milk fever: a downed cow. Without proper treatment, milk fever can lead to death. Treatment generally involves calcium injection by intravenous, intramuscular or subcutaneous routes. Typical milk fevers respond well to treatment. I always administer a follow up dicationic or colloidal calcium injection to ensure persistent calcium stimulus for mobilization. The rapid drop and the decreased mass of the calcium pool prior to parturition, and the failure of calcium absorption to increase fast enough after the onset of lactation, can predispose animals to milk fever or hypocalcemia.There are other probable causes that have been associated with inducing milk fever. Diagnosis: history, clinical signs, blood biochemistry and response to treatment. As a result, about 80% of milk fever occurs within one day of calving. Urine acidity is affected by these changes in the cow's acid-base status, Table 4.
