  • What is Bovisel plus
    Bovisel plus is a mineral mixture for cattle that was designed by- and for dairy veterinarians.

    In order to identify mineral deficiencies existing in various meat and dairy farms, a number of spot were checked. Based on these results, a technically perfect mineral mixture was formulated to meet the high demands for minerals and trace elements that animals have today.

    We came to this composition:

    We have chosen Bovisel plus packing in 25 kg bags. The daily dose is 50gr/animal. It should be used at least 40 days to build up reserves quickly and save, but it can of course also be used as a base mineral mixture during both winter and summer season.

    As you can read from the table we have opted for essential vitamins and minerals at high concentrations. We found that the current mineral mixes contain too little or no biotin and selenium, mainly in the inorganic form. Also copper, zinc and manganese are not often used as chelated minerals.

    Why is extra Selenium needed? It is well known that the Western-european soil is very poor in selenium which is reflected in low levels in our fodder. The concentrations exceed 0.1 mg Se / kg feed very rarely. This creates a rapid Se deficiency and Se should be added to reach higher values.

    What is organic Selenium? Most mineral mixes contain Se in the form of inorganic Se (sodiumselenite) to a maximum dose of 0.5 mg Se per kg feed.
    In our mineral mix Se is added as organic Se proteins, mainly methionine and cysteine, where the sulfur molecule is replaced with a selenium molecule. Because the Se mineral is contained in a protein structure, protein is also absorbed from the gastrointestinal tract. This makes the Se digestibility to four times higher compared to Se from sodiumselenite. Organic selenium is also the form in which Se is present in plants. In the feed produced, organic Se is already present. However, the final Se levels in raw materials (cereals, silage) are on the low side. They seldom exceed 0.1 mg Se / kg feed. This creates Se-deficiency and therefore Se should be added

    The use of organic Se compared to inorganic Se has the following advantages:

    * much better absorption: three to four times greater absorption from the intestinal tract (by active transport).

    * storage in tissues: organic Se excess is stored in tissue proteins (eg muscle) in the form of Se-methionine or cysteine, whereas inorganic Se excess is excreted through the bile and urine.

    * placental: Calves are born with two to three times higher Se levels in their blood. Inorganic Se barely crosses the placental barrier.

    * higher Se concentrations in colostrum and milk, so calves have even higher Se levels after birth

    * Improved meat quality: less drip (fluid loss) with a tenderer piece of meat and better meat color results.

    What are chelated minerals?

    Trace elements (zinc, copper, manganese, selenium, cobalt, iodine, iron ...) are essential nutrients. Natural foods such as corn, wheat, soy, etc. contain necessary trace elements, but in a form that is difficult for the animal to use. Moreover, they often feed in these low concentrations. Hence it is imperative to trace additional supplementation, especially when there are shortages.

    During the chelation process, the mineral (trace element) bound to a protein. These chelates are stable, neutrally charged complexes, trace elements that protect against chemical reactions during digestion. This increases their bioavailability.

    As for copper, the chelated form is also very appropriate when high concentrations of molybdenum, sulfur and/or iron (eg in drinking water) are to be expected.

    The impact of biotin?

    Biotin is a vitamin (vitamin B 8) whose effect is well known. Numerous studies have shown that the administration of biotin the quality of the hooves is significantly improved. Biotin is essential because during two key steps of the horn production: the production of keratin and the formation of the intercellular cement (which makes for a strong cell-cell adhesion).

    Besides his interest in horn formation, biotin is a cofactor in several important enzymes that control the production of propionic acid in the rumen for the production of glucose from propionic acid in the liver and the fat and protein metabolism.
