- Anionic Salts



Effective – Provides anionic salts to help your dairy cows mobilize calcium, thereby aiding in the prevention of milk fever. Palatable – It is prepared in an aromatic liquid base which is then mixed with the dry ration, cows find it more palatable than dry chloride supplements and are unable to separate it from their feed. Economical – Compare the cost of Bovachlor to other leading anionic products.

Milk fever occurs in dairy cows when, at the onset of lactation, blood calcium levels drop because cows are unable to pull enough calcium from their feed and their bones to support milk production. Unfortunately, by the time this is obvious, the cow has often died. As the cow ages, the likelihood of developing milk fever increases.

Research has demonstrated that prepartum feeding of higher levels of anions such as those found in chlorides and sulfates- relative to cations such as those in calcium and magnesium-enhances calcium mobilization, decreasing the incidence of milk fever. High anionic diets are most effective when started 3-4 weeks before parturition. They are typically fed for no less than 10 days and no more than 30. In a 2001 field trial, Harris and Beede demonstrated the effectiveness of adjusting the diet from a cationic to an anionic diet, as shown in the chart below.

The Right Anionic Diet
To arrive at the high anionic diet, typically dry anionic salts are added.
Examples of anionic salts and their effect on urine pH are shown below.

Unfortunately, to be effective, high-anionic diets are typically unpalatable. Hydrochloric acid and ammonium chloride provide more anionic potential than the other salts listed.

Therefore, Bovachlor provides a significant concentration of these highly effective chloride sources in a medium that minimizes or eliminates palatability problems as well as the cow’s ability to pick it out of the ration.

Urine pH Testing Is Important
Feeding Bovachlor requires regular urine pH testing to make sure the proper amount is being fed.

Most dairymen start by feeding 2# of Bovachlor per head per day. That amount is adjusted based on urine pH of 6.2-6.8 for Holsteins, or 5.5-6 for Jerseys. (Use the mean of at least 8 animals to determine urine pH). 1# to 1.5# is a typical feeding rate to maintain proper urine pH.

It is also important to monitor total feed intake. This means dairy cattle on Bovachlor should not have access to free choice hay or pasture. This is important because there are times when cows will eat less or more dry feed, and the percentage of Bovachlor within the total feed intake should remain fairly constant.

It is important that a balanced diet be maintained while feeding Bovachlor. Consult with your nutritionist.


Greg Bethard, Ph.D., of G&R Dairy Consulting, Inc. in Wytheville, Virginia tells us, 'I have been very happy with the results of Bovachlor. It has 3 main advantages in my close-up rations: price, palatability, and effectiveness. Bovachlor is an economical supplement and it is more palatable and appealing to the cows than dry chloride sources. We feel that separation and sorting is minimal or non-existent with Bovachlor. Urine pH’s have been consistently in the 6.0-6.5 range. Overall, we have been very satisfied with Bovachlor.'
