I –
Procedure
The experiment was
conducted over a period of two months (May–June 2006) on two groups
of 24 milk cows during the
lactation phase. The feed for the experimental group was
supplemented with BioAktiv at the rate of 5g *
per cow per week, administered in two doses and distributed on the
feed ration using the top-dress method.
II – Results
Only 16 comparison pairs were kept in the
experiment for its duration.
A – Milk production
No differences recorded

B – Milk quality
The milk was analysed twice a month in order
to measure the fat (TB) and protein (TP) content as well as the
cell count of the milk produced by each cow in the experimental
group.

III – Conclusions
The experiment showed that BioAktiv has a
positive impact on the fat content and cell count of milk as well as
the condition of the cows’ hooves.
