Silage analysis.

[redsloe]

Had a couple samples done, first time for me and haven't a clue what to read into it!
Protein looks good but does anyone want to comment as to what else I should be taking note of.
Feeding to beef cattle of all ages.
First cut,

Second cut,

Cant work out how to rotate the pics!

Are they not both the same one?

from my point of view when looking at a ration key values are Dry matter, Crude Protein, ME, fibre and oil.
DM is good. protein is good, decent fibre but Low in energy (ME). Seen a lot of high protein silages from other farmers similar to this.
its good silage for growing cattle for sure. My personal view it wouldnt be great for finishing cattle in becuase that Low ME, but would be good enough to cover CP required for a finishing ration. persoanlly i would build up that energy desity with some high energy straights like ground maize, confectionary or moist product like bread.
hope my two cents helped.

Thanks, I was expecting a higher ME because it was both cut relatively early and leafy red clover.
Not fattening many on this farm this winter, mainly youngsters.

The ME is simply D value (64.6) x 0.16 = 10.3.

That's how all silage ME figures are estimated. And the D value depends on two factors. Stage of growth at cutting and the accuracy of the sample taken for analysis. These are the main factors, but D value might also be affected by the DM at ensiling and the actual success of the fermentation process.

Like all analyses, the results are just as good as the sampling and analysis process. I remember doing quantitative analysis with a load of other students. Even with the same samples, we ended up with very different results.

The analysis method/calculations used are also pretty well irrelevant if there is much clover in the crop I understand, as is the case with this sample (red clover).

My worry would be high V.FAs in the first sample, and the fermentable proteins and / or carbohydrates high in both samples.
That will need careful buffering.
