TranzSol™ has been formulated by leading ruminant nutritionist Joe McGrath and has proven to work in dairy herds across New Zealand for over 10 years.
During transition a cow changes from an animal that expels no milk, to an animal that produces huge amounts of milk overnight.
That puts huge metabolic demand on her entire system, and what happens in those few weeks shapes the rest of her season.

They all start with deficiencies in a cow’s calcium and phosphorous storage levels in her bones.
The impact of hypocalcemia (low blood calcium levels) alone is massive industry wide. In New Zealand, approximately 40% of the national herd will experience either clinical or sub-clinic milk fever*. This results in further problems with calving, milk production, fertility and mastitis through the season.

flow-on effects: calving, fertility & mastitis issues that compound through the season.
To enable cows to transition effectively, there are three things we must do.
This reduces the chance of ketosis, acidosis and displaced abomasums. It also helps build capacity, so she can eat more, faster, post-calving.
Reducing the incidence of mastitis and retained placentas, and the subsequent infections that follow.
The most important point. A cow with milk fever won’t eat (impacting point 1) and will have lower immunity (point 2). Get this right and the rest follows.
Most critical
Calcium carbonate combined with a patented form of activated vitamin D (Hy-D®) ensures she can receive an effective, regular dose of calcium during transition from her diet, to support the natural bone mobilisation process, and reduce the demand on her bones.
Hy-D enables her to absorb that calcium.
New Zealand studies* have shown, under a TranzSol™ transition diet, calcium blood concentrations have been lifted by 30% compared to DCAD diets.
*Independent NZ trial data, available on request.
Fewer cases of milk fever and ketosis through the herd.
Fewer bags, bolus's and bottles
An all-in-one transition option
*max volume of grass is 6kg
More milk in the vat. Less stress in the shed.
*Maximum volume of grass: 6kg DM in pasture-based systems.
A smoother, more productive transition period.

"We knew we needed to make some serious changes to the herd’s diet. We went from dealing with 15-20 cases of milk fever per day to 10 per year. The dairy’s overall herd health and productivity have soared.”

"I thought I was going to have metabolic issues for Africa. When they calved, I could not believe the udders I was seeing. 2.1 milk solids a day from the 1st of August, and 90% of our herd in calf in 5 weeks. You just didn't think it was possible."

"Production levels have definitely increased, but the benefits extend beyond just numbers. Improved cow condition and overall health are huge wins. It’s not just about production, good health leads to great production.”
Pick the option that fits how you already feed minerals — your rep can help you decide.
TranzSol™ Complete is for the user who wants to make sure everything is mixed effectively and in the right proportions. It's all in one bag.
Dose Rates: 480/cow/day for 14 days pre-calving + cololstrum herd.
Start when cows being to show signs of springing (typically 14 days before calving) and continue to colostrum herd.
TranzSol™ Nucleus is formulated for those who can utilitise their own limeflour and magnesium chloride, it still contains all the vitamins, trace minerals and Hy-D®. It is recommended for use with Mixer Wagons.
Dose Rates: 100g/cow/day for 14 Days* pre-calving + colostrum herd (plus 100g MgCl and 280g Limeflour).
Start when cows being to show signs of springing (typically 14 days before calving) and continue to colostrum herd.
The questions we get asked most in the shed and on farm calls. Still not sure? Our team is a phone call away.
Talk to a repStart TranzSol™ when cows begin to show signs of springing, typically 14 days before calving. Continue feeding through the colostrum herd. Cows must consume TranzSol™ for a minimum of 10 days pre-calving to get the full benefit.
TranzSol™ Nucleus is fed at 100g/cow/day. TranzSol™ Complete is fed at 480g/cow/day. Both should be mixed evenly through the feed.
TranzSol™ Nucleus is for farmers who have access to their own magnesium chloride and calcium. TranzSol™ Complete includes the magnesium and calcium in the one bag, making it a simpler all-in-one option.
Yes, TranzSol™ can be fed with all-pasture diets. However, grass and grass silage intake should be kept to no more than 6kg/cow/day before calving for best results.
TranzSol™ is formulated to reduce the risk of milk fever, ketosis, acidosis, displaced abomasum, mastitis, and retained placentas by supporting calcium absorption, rumen adjustment, and immune function through the transition period.
There are no withholding periods for either meat or milk.
