7. General observations
• X-ZELIT
– Helps minimize the frequency of metritis, displaced abomasum,
retained placenta
– Hard to really see an improvement of the milk production in farms
– No problem of consumption of pure X-ZELIT with Holstein cows, but
real problem with Normand => feed compound
– Not easy to give the product when cows are outside (field)
– More than 70% of the farmers will go on with the product
