Benefits of the Harvestore for Corn Silage

A Feed Processing Centre

That can provide a consistent supply of quality feed year round!!


And avoids the all too familiar "Fall Slump" !!!


 Storing corn silage in an oxygen-limiting Harvestore silo can provide benefits to dairymen and provide advantages not common to other conventional feed storage systems ie. concrete towers, bunkers, bags etc. The following points may be considered when incorporated in a well managed and properly balanced feed program




  1.   1.In conventional storage systems to achieve adequate packing rates, moisture recommendations and relatively shortened theoretical cuts are required to optimize the exclusion of air (oxygen from the stored feed. The Harvestore Structure's oxygen-limiting feature allows a longer chopped material to be stored which provides effective fibre to promote cud chewing for saliva production (natural buffering).


  1. Corn silage normally has low ph .Increased moisture levels increase acidity and can reduce dry matter intake. A ph level in the range of 3.8 – 4.2 is commonly expected. The lower moisture levels of feed storage possible with the Harvestore system can reduce the total amount of acid entering the rumen.


  1. Wetter corn silage in conventional storage is prone to freezing. The dark (cobalt) blue bolted  glass fused steel sheets of the Harvestore structure attract the sun’s rays and allow the feed to slide past the smooth side walls even if some freezing should occur.


  1. Reducing the acid content of the feed and increasing the effective fibre (length ) will aid rumen function and can reduce the possibilities of acidosis, laminitis off-feed etc. .Improving rumen health can also translate into improved production and increased levels of butterfat.


  1.   An adequately sized Harvestore structure can provide fermented corn silage for year round use. First in and first out bottom unloading provides fermented feed for the herd even while filling the silo thereby avoiding the all too familiar “ corn silage slump” as the cow’s rumen(bugs) adjust to the sudden change of “green chop”.


  1. Avoid the three week delay of returning to fermented feed—the normal time required for green chopped feed to “pickle”.


  1. Commence filling without delay raising silo unloaders .Lowering unloader to resume feeding when weather interrupts harvest and once more raising to return to filling.


      8. No inoculants or additives required in the Harvestore as are normally

        recommended with conventional systems to reduce molds through rapid fermentation.

         = Cost Savings

 Harvestores reduced exposure to oxygen minimizes the ability of mold spores to grow and undesirable yeasts.



9.  Oxygen-Limiting Harvestore has the lowest dry matter loss of all other feed    storage systems in the industry.


  10.  When maintaining prescribed operational guidelines set out in the Harvestore
Structure Manual, highly toxic and dangerous (nitrogen dioxide gas) commonly
found around “open” systems can be better contained, thereby minimizing risk of
exposure to personnel.


  11. Safe,No climbing, Cost effective, Low Structure Maintenance Concrete silos require periodical drying out and checking for deterioration (acid rot)


 It is currently recommended that a minimum of 2-4 months in reserve storage for corn silage is required to achieve a more complete level of fermentation.
