After many years of problems the breeder contacted us to try a final attempt to solve his problems

most of the problems were bacterial , also rust contamination in the drinking cups , tubes and tanks.

after the first round there was already a big difference ,  never he had such good results in years !

alfter the second breeding round ( 6 weeks ) the results were even better.

now 7 rounds later the breeder is still very satisfied with Harsonic and his old problems are solved.

also he sees a better food conversion !
