Many time diets do not perform as prescribed, due to the many variables involved and the associative effects of feeds and forages, it is difficult to isolate the problem. A new approach using gas production techniques can assist nutritionists and producers in gaining a better understanding of the digestion kinetics of feeds and forages. This information can be used to estimate milk production and provide the end user with options on how to adjust the ration. 15 years of gas analysis has allowed us to refine and perfect the gas production system. This system, along with standard analysis an In situ steps, allow for the definition of Kds at multiple time points as well as measuring when maximum rates are achieved.

Turn Around Time

All samples take between 7 to 10 days for analysis to be completed once they arrive in Ottawa.

Sample Size | Preparation


  • Use a bale core sampler to reduce error.
  • Minimum of 15-20 cores per lot.
  • A "lot" is defined as forage harvested within one day, from one field, for the same cutting and maturity, and is similar in amount of grass, weeds, rain damage etc.
  • Place cores in a clean plastic bag and label properly.
  • Do not divide or mix hay samples; this increases the separation of leaves and stems.
  • Submit a 1-pint size sample for analysis.

Silages-Tower silos
  • Take fresh samples, unless specifically testing spoiled material.
  • Collect 15-20 handfuls from silo unloader into a plastic bucket. Mix thoroughly.
  • Submit a 1-pint to 1-quart sample in a clean freezer bag.
  • Remove as much air as possible and seal tightly.

Silages Bunker
  • 1A. If feeding a TMR- load material into TMR Mixer and mix well. Take several sub samples, place in plastic bucket and mix well. -OR- 1B. If not feeding a TMR- Collect several sub samples from different vertical layers of the silo face. Take several handfuls from freshly exposed forage after the day'' feeding has been removed.
  • 2. Combine sub samples and mix well. Reduce sample size to 1-pint using quartering technique***
  • Submit a 1-pint to 1-quart sample for analysis.

Mix TMR per normal routine.
  • Place containers (buckets or garbage can lids) along the bunk. A minimum of three containers should be placed at the beginning, middle and end of the bunk. Using more containers will increase the accuracy of the analysis. Unload the TMR.
  • Mix the material collected in the containers on a tarp. Thoroughly mix the sub samples picking up one corner of the tarp and pull toward the opposite corner of the tarp. Continue this procedure with each of the corners 3 times.
  • Reduce the sample using the "quartering technique" listed below. Submit a quart size sample for analysis.

***Quartering Technique***
  • Sometimes when forages and rations are sampled, the total of the aggregate samples is too large to send to the laboratory. Quartering allows reduction of the sample size and maintains the representative sample.
  • Mix the entire sample thoroughly, then pour it into a pile on clean paper or plastic.
  • Divide the sample into four equal parts (quarters), saving two opposite quarters. Be sure to save the fine material at the bottom of the saved quarter.
  • If the sample is still too large, repeat the procedure.
  • HAY SAMPLES SHOULD NOT BE QUARTERED, since leaf loss can drastically affect analysis results.

Sample Shipping and Handling
  • Proper handling is important. Unstable silages can change without proper handling.

Remove as much air as possible and seal tightly.
  • Cool or freeze sample until mailing.
  • Send sample(s) the quickest means possible to laboratory.
  • Avoid mailing samples over the weekend and holidays.
  • Pint sized samples are adequate for most analysis.
