In case of calf diarrhoea

BEWI-SAN Prevent C

The challenge:

Newborn calves are particularly vulnerable as their active immunity is not fully developed. Digestive disorders in the first two weeks of life are a major problem on many farms. They can have many causes, such as high calving and pairing densities in calf pens, fluctuating ambient temperatures, etc. If a farm is affected, even the best colostrum management and the strictest hygiene measures alone will usually not help.

Stabilising the physiological digestion of the newborn calf in the first few weeks of life ensures successful rearing and good weight gain from the start.

Your benefits:

  • Proven in practice: more than 370,000 calves successfully fed
  • Contributes to whole milk feeding and delivers with vitamins and trace elements
  • Stabilises digestion
  • Easy application in milk
  • Suitable for “GMO-free” feeding (VLOG-verified)
  • Directly from the manufacturer

Our solution:

Our dietary feed BEWI-SAN Prevent C was specially developed to stabilise the physiological digestion of newborn calves.

  • NEW: Now additionally with carob gum, has a supportive effect on unspecific digestive problems due to the high proportion of swellable fiber
  • Special formulation with organic acids supports digestion and stabilises the colostrum for at least 12 hours
  • Lactic acid bacteria protect the intestinal mucosa and promote the natural intestinal flora
  • Optimal combination of essential vitamins and trace elements prevents signs and symptoms of deficiency
  • With appetising fenugreek

Application area:

To stabilise physiological digestion if there is a risk of digestive disorders in the first 14 days of life.


Use BEWI-SAN Prevent C from second meal onwards during the first 8-14 days of life. 10 g BEWI-SAN Prevent C per litre of milk. At least 60 g per calf and day.


Remember to give your calves the best living conditions. We recommend thorough cleaning and disinfection with effective substances (e.g. ALDECOC® CMK).
