The revolutionary BioPac’r™ is bound to play a key role in the livestock farmer’s fodder flow programme, especially medium-sized to small farming enterprises. It also presents a world of opportunities to silage-making contractors.
The BioPac’r™ is made in America with high quality steel, built to stand the test of time. BioPac’r™ is supplied by a manufacturer that also builds other Powerhouse Brands like CAT, John Deere and Case New Holland. The BioPac’r™ promises ease of use, simplicity and great results, every time.
In a recent test conducted by Richardt Venter of Agsci Unlimited, kikuyu silage was made in BioPac’r™ bags for demonstration and trial purposes. Due to a very quick and effective cut-off of the oxygen achieved by the BioPac’r™, supported by a very high compaction tight seal, this system is able to:
Ensure a good primary fermentation process.
Create silage that is very stable after aerobic exposure.
Prevent any form of yeast or mould growth.
Achieve high compactions and lends itself to finely chopped material, waste material or small quantities of material.
Temperatures inside the packed bags are below 20°C and through the absence of microbial activity such as yeast and mould, there are no mycotoxins present. The BioPac’r™ is also suited to a very wide DM (dry matter) range.
Kikuyu silage was made in BioPac’r™ bags for demonstration and trial purposes. Kikuyu grass was chosen based on the difficulty to preserve this type of forage: if this could be done well, easier crops will be simple to do.
The nutritional analyses proved good for kikuyu silage and indicate good preservation of nutrients. The BioPac’r™ coped very well with wet material, and is suited to a very wide DM (dry matter) range.
The primary fermentation process was efficient, as indicated by a good level of VFA’s (volatile fatty acids) and pH below 5 – a good pH for this type of crop. This was probably due to the very quick and effective cut-off of the oxygen achieved by the BioPac’r™.
The silage proved to be very stable after aerobic exposure, measured by a constant pH and no signs of secondary fermentation after five days. This is especially remarkable as the crop was not treated with silage inoculants, and it was very wet. The main contributor to this result may have been the good compaction and early cut-off of oxygen through the BioPac’r™ system.
Microbial spoilage organisms
There were no yeasts or moulds present in silage made by the BioPac’r™. Again this is due to the very quick and efficient cut-off of oxygen, as well as the efficient compaction and tight seal achieved by the BioPac’r™.
The compaction achieved clearly shows the ability of the BioPac’r™ to compress forage effectively and sufficiently. If material that is finely chopped is ensiled, the compaction will be even higher. The BioPac’r™ lends itself to finely chopped material, waste material or small quantities of material.
Temperatures below 20°C inside the bags clearly indicated a finalised primary fermentation and stable silage. This is achieved by good compaction and a tight seal from the plastic bag.
There were no detected mycotoxins anywhere. This is achieved through the absence of microbial activity, like yeast and mould, which were not present. When a tight compaction and seal, achieved by the BioPac’r™, are then added to the process, there is no opportunity for mould growth and mycotoxins formation.
