Mervit Mineral Feeds reduce the risk of milk fever

tue, 1 jul 2014
Milk fever is one of the primary health problems in Dutch dairy farming. Although a cow with milk fever can generally be treated successfully by means of an infusion, prevention is better than cure. Feeding of a dry period mineral feed is essential in this.

Milk fever arises mainly in older cows, when through the initiation of the milk production, less calcium can be supplied than is removed from the blood by the udder. There is in principle sufficient calcium present in the bones, but if the cow is not able to mobilise this reserve, the calcium level in the blood falls. The result is that muscle function reduces and the animal can for example no longer stand up. The most obvious symptom of milk fever is that the cow feels cold, particularly its ears. There are however also side effects that are less visible. A cow with milk fever consumes no or little feed and there is an increased risk of for example retention of the placenta.

For a smooth start to lactation, prevention of milk fever is therefore better than treatment afterwards. Stimulation of the calcium metabolism is the most important factor to reduce the risk of milk fever. A restricted calcium level in the feed in combination with a high level of magnesium are the basic principles. By formulating the dry period diet with a low DCAB, the animal’s calcium metabolism can be increased before calving, through stimulation of the calcium uptake from the gut and the bone.

Besides a correct mineral balance, sufficient trace elements and vitamins are important for easy calving and a healthy calf. Mervit DRY S is ideal to meet the dry cow’s need for minerals, trace elements and vitamins. For specific cases, where it is necessary to correct the DCAB with the addition of anionic salts, there is Mervit Close-Up. With Mervit DRY S and Mervit Close-Up, the number of cases of milk fever can be reduced by 60 to 80%. That’s offering your cows a healthy start to lactation!
