Norbrook Laboratories has launched a long-acting cattle bolus which it says will reduce the risk of Milk Fever. 

According to the company, Calcitrace D3 is the first and only long-acting bolus to offer slow and fast releasing calcium to provide sustained calcium levels for 48 to 72 hours. In addition, Calcitrace D3 provides Magnesium, Phosphate and Vitamin D3 making it the most comprehensive bolus available.   

Calcitrace D3 is smooth gelatin coated bolus with a rounded tip designed for easier administration. Norbrook says it is smaller than other boluses making it less likely to cause trauma on the orpharynx during administration.

Dr Barry McInerney, Norbrook's GB Veterinary Advisor said: "Milk Fever is a common metabolic disorder in dairy cattle which generally affects older, high producing cows and is caused by a rapid decrease in calcium concentrations in the blood just before calving. It is estimated that 3-10% of cows are affected by Milk Fever with a cost of more than £200 per incident so it is crucial that farmers and vets reduce the risk as effectively as possible.

"Norbrook's new Calcitrace D3 bolus which should be administered just before calving, provides higher calcium blood levels during the critical 12 - 48 hour post calving period and provides sustained increased levels for well beyond 48 hours. With the addition of Magnesium, Phosphate and Vitamin D3, Calcitrace D3 provides additional protection against Milk Fever."

Andrew Hillan MVB MRCVS, Director of Veterinary Sciences at Norbrook, led the development of Calcitrace D3. He said: "The launch of Calcitrace D3 is another illustration of the very high quality of technical expertise that exists within our research and development department and underlines Norbrook's commitment to developing high quality and innovative products. It comes from a strong and exciting pipeline of new products which we will bring to the market over the next couple of years."
