A transition cow vitamin and mineral supplement to aid in the prevention of milk fever, maintain immune response and benefit subsequent re-breeding.

Tranzsol™ from Sollus is formulated to be the easiest and best transition supplement for New Zealand dairy cows. It incorporates antioxidants, magnesium and, most importantly, Rovimix Hy-D®. 

Avatec® / Bovatec® is a registered product under the ACVM Act 1997, A10829.

Nutritional Benefits

Using anionic salts (Tranzsol™) in combination with the vitamin D metabolite, Rovimix HyD® is proven to have beneficial effects in hormonal and physiological adaptation of the cow to mobilise calcium, reducing the risks of milk fever. Providing the essential minerals and vitamins during this crucial period reduces the risks of metabolic disease, has a beneficial impact on subsequent re-breeding and is important in maintaining immune function.

Sollus Tranzsol™ is formulated for diets containing approx. 50% pasture, however, it can still be fed with all pasture diets.

Feed a maximum per day of 6kg grass or grass silage.

Cattle Feed Storage on Farm

As with any grain or meal feed products need to be kept dry as moisture combined with heat can cause fungi to grow. Common on farm storage methods are: in a shed or unused fertiliser bin; in a covered pit; on a concrete pad; or in a cutting, covered with plastic sheet and tyres. Most feed should be used reasonably expediently (within 40 - 50 days). The longer you plan to store feed products the better your storage facilities need to be.
