Transition milk is the milk cows produce after colostrum and before they produce what we consider milk. It is higher in most nutrients and antibodies and is highly beneficial to feed to calves. However, the effect of a high total bacterial count in transition milk and the risk of spreading disease offset these benefits. Using Transformula is the perfect solution and gives baby calves what baby calves need.

Bonanza Calf Nutrition has developed the 1st transition milk replacer for calves.

Transformula is not a milk replacer it’s a transition milk replacer.  Transition milk is produced by the cow and its function is to transition the calf’s digestive system or gut (abomasum, small and large intestine) from a set of inert organs into the main sites of digestion for the young calf.

The gut has no function in the foetus and only really develops in the last month of gestation. This is why underweight and premature calves are more prone to digestive problem.

After the calf is born, the gut must transition from an inert organ to one full of acids and enzymes. The gut is also very porous at birth, which allow colostrum antibodies to be absorbed whole.

Feeding transition milk ( milk produced by the cow from day 2-4) is key to encouraging the production of acid and enzymes in the calf and the full closure of the gut wall.

Bonanza Calf Nutrition has developed the 1st transition milk by identifying the key elements of transition milk.

The calf is very limited in what it can digest in the days after birth and providing the wrong feed at this stage limits gut development, gut closure, energy intake and the ability of the calf to fight infection.

The selection of pasteurised and low heat-treated protein ingredients for Transformula is key as is the selection of short chain fatty acids to ensure the calf can utilise the energy and protein in the transition milk replacer. Other feed ingredient shown to promote gut health are added at levels found in transition milk.

Farmers using Transformula have far less problem with scour which saves time and money on calf treatments

Using Transformula limits the risk of disease spread in the herd and costs about €5(£4) to feed a calf for ten day over milk of milk replacer.

The pay back is less calf treatments, stronger calves at 2 weeks old and more even calves.

Transformula is not a magic bullet – it just lets nature take its course.
