Method of operation:
1. Sampling with a spoon;
2. Put it into a stainless steel basin;
3. Put the Cargill sieve into the bucket;
4. Pour the sample in the stainless steel basin into the sieve;
5. Install the spray gun water pipe;
6. Rinse the sample;
7. Until the sample is layered;
8. Observe the stratification and judge the pathology.
Analytical reference:
The target for the top tier is less than 10%, less than 20% is
acceptable in early lactation as the rumen is still in adjustment
or the new production diet itself is high in NDF. The target for
the middle tier is less than 20% and the target for the bottom tier
is greater than 50%. As a wide range of recommendations is given,
it is recommended that it is sufficient to observe the volume of
residues. The reasons for not meeting the target for digestibility
are often cross-cutting and not caused by one item. For example,
some farmers do not do well with silage, which is poor quality
roughage, but usually also means that there is not enough
fermentable starch in the period diet. For the nutritionist, it is
important to take into account the farm's recipe, the cow's
performance and the observed manure sieves to determine this, find
the cause and go about adjusting the recipe or management.
