Silo Sampling - For a Perfect Forage Analysis (Using a Tool)
The quality of basic feed is crucial for the performance of animals. Only through a feed analysis can the farmer determine if the produced forage meets their requirements and has the desired quality. Accurate feeding can only be ensured with precise values. Relying on rough estimates and assumptions is not advisable.
The significance of all analysis results depends on the quality of the sampling. This is the first and most important step in forage analysis. Sampling requires utmost care because errors made during the sampling process cannot be corrected in the analysis. Samples should be taken in a way that avoids contamination. The equipment and containers used should be clean and dry.
The sample of basic feed should allow for the most accurate characterization of each silo or batch of silage. At the time of sampling, the silage should be well fermented. Depending on the type of silage, this process takes at least 4 to 6 weeks.
- Sampling probe
- 10-liter bucket
- Sano sampling kit
Procedure for Silo Sampling using a Sampling Probe:
- The silo should be sampled at least in 3 different locations
- The outer and top layers should be discarded to a depth of at least 10 cm
- If the covering cannot be completely removed at the sampling site, make a cross cut at that location. The cut can be sealed with adhesive tape afterwards
- Penetrate the silo completely through all layers
- Collect 3-5 liters of sample material in a 10-liter bucket
- Thoroughly mix the sample material with your hands
- Transfer 1.5-2.5 liters of sample material into the sample bag (maximum 1,000 g)
- Remove as much air as possible from the sample bag and seal it carefully (if possible, use a vacuum device and vacuum bag)
- Complete the analysis form
