The Koster Bale Probe Sampler is the only Hay & Forage Probe you will ever need. Highly recommended for the fast and convenient collection of bale samples for testing purposes.
Attach your Cordless or corded 1/2″ Drill for Penetrating Action. Collect hay samples easily and prevent contamination from handling. Attach drill, cut thru forage, cleanout rod pushes up to 20 hay core samples into 1-gallon standard zip-lock bags which are suspended from our see-thru collection container.
Animal ration balancing requires a forage analysis. Proper hay & forage analysis requires taking a good forage sample. Taking a good sample requires a bale probe. The Koster Bale Probe allows recommended 5/8″ samples of chopped forage to be gathered quickly and easily without contamination from handling.
Hay Probe Sampling Procedure: Care should be taken when sampling hay. Samples should be uniformly obtained from several bales (10 bales minimum) throughout each sampling lot. Avoid sampling only one or two areas in the lot. Each sampling lot should be defined by date baled, cutting, forage type and pasture, and the owner or farm name. Indicate if the hay was rained on while curing. Any significant event that could cause changes in forage quality would be a reason for separating those samples into a different lot. For a large sampling lot (more than 50 bales), it is advisable to gather several hay samples for analysis.
Baleage: Drill to the full depth of the hay probe in at least 12 random locations throughout the wrapped bales. Use the cleanout rod to simply push the sample into the baggie. When finished tape the 1″ holes in the baleage made from the sampler.
Handling: The handling of the hay sample is important to get accurate results. The sample cannot be exposed to air, as it will lose moisture. Samples left in the sunlight usually will have moisture condensation on the plastic bag. Poorly sealed samples will lose fines or a portion of the sample. All of the above will affect the results. Care should be taken to keep samples in a cool location and packed securely to prevent sample spillage. Be sure that identification is secure and is written with a marking pen that is waterproof. Shipping containers should be the correct size to prevent excessive movement. Zip lock bags need to be packed securely. Do not hold samples for an extended time. This just adds to the possibility of errors.
