Mini Fermenter for Nutrix
With the mini fermenter, WEDA have developed a system for the fermentation of smallest feed amounts, by which optimal feed provision for suckling piglets from the first day of life onwards is now achieved. First experiences gained in practice confirm a much better development of the suckling piglets with positive effects all the way to fattening.
The ferment is produced in a 125 l mini fermenter. The insulated container is equipped with an agitator and an integrated heating. Very important: the container has to keep a temperature of 38°C for 24 hours to allow for the lactic acid bacteria to develop properly. And this is how it is done: after thorough cleaning of the fermenter, 80 l of water at 40°C are filled into the fermenter. Parallelly, the fermenter heating is in operation. Then 20 kg of grain mixture are stirred in and finally lactic acid bacteria are added. Then, the agitator is switched into interval operation in order to keep the entry of air into the feed as low as possible. Via time switch, the unit then stirs the container only four times a day for five minutes each. The heating remains in operation for 24 hours. Then the fermentation process is finished and feeding out can take place now.
The proportion of ferment in the feed ranges at 9% of the total ration from the first day of life onwards. From day 14 onwards, the proportion of ferment is raised to 12 to 20%. The feed dosed out by the Nutrix is supposed to have a pH-value of 4.6.
A unit with 500 sows requires 100 litres of ferment for approximately one week.
Advantages of fermentation:
- Better feed uptake with increasing feed conversion
- Reduction of cough and diarrhoea problems
- High gains, better growth
- More homogeneous groups at weaning
- Positive intestinal health, more vitality
- Reduction of tail biting
- Lower mortality rate
