The need to maintain feedmill and feed bin biosecurity is more important than ever, now that antibiotic resistant species of bacteria are a real threat. Heat treatment alone is not sufficient because after heat treatment the feed is prone to reinfection.
Dust in the mill, in storage bins, trucks and farm feed bins can bridge the heat treatment barrier. The same is true for people and maintenance work both at the mill and on farm. pHorce can be used as part of the anti-salmonella programme for pig and poultry producers as well as breeder farms and for drug free biosecurity programs.
This product can also be used in four different ways depending on the mill design and the scale of the biological challenge.
1. Selective treatment of susceptible Raw Materials
Raw materials such as palm kernels, cottonseed meal, meat meal and fishmeal can be treated with pHorce at rates up to 30kg/t to decontaminate oily raw materials as a safe alternative to liquid acids, or used at 2kg/t to prevent recontamination during storage.
2. Routine flushing of the feedmill
It is now common practice to flush a feedmill after cleaning by mixing 50kg of pHorce in 100kg of wheatfeed, polenta, ricebran, (or similar material) and passing this mixture through the mill. This will ensure that all surfaces and dust collection hollows are filled with a strong pHorce blend to reduce the risk of subsequent contamination. This must be done once a month, however some mills where either the mill design is old or Salmonella control systems are essential, such as in the production of breeder feeds, this can be done weekly. Mixed product can be bagged off after use and then used as 30% strength pHorce, representing a true no loss biosecurity system.
3. Spot treatments
There are several sites within a feedmill that are especially prone to colonisation by Salmonellae and other bacteria. In some mills individual scoops containing 250g pHorce can be added directly to the conditioner, cooler, conveyers and finished stock product bins. This material is allowed to flow through the mill but provides a particularly potent solution to bacterial contamination at these Critical Hazard points.
4. Feed transfer
When using blowers to fill feed bins on farm it is possible to add a scoop of pHorce to the blower line before attaching it to the vehicle. When the feed is blown the pHorce will attach to any damp material in the lines and also dust out the empty part of the feed bin whilst adding a thin layer of pHorce to the surface of any remaining feed. This creates a biosecurity barrier between the fresh and the old feed.
