Grass Silage Sample Results 2014

 

The results from over 1,400 grass silage samples sent to the Dairygold laboratory for analysis are in, and there is very little difference in the average DMD (feeding value) of silage made in 2014 versus 2013 (69.4 versus 69.1) or in the crude protein level (11.7 versus 11.8). Averages from the last five years are shown in the graphics below.   
Dairygold Silage Analysis Average DMD by Year (2010-2014)
 
Dairygold Silage Analysis Average Crude Protein by Year (2010-2014)
 
Averages can hide a multitude however; and there are large variances between and within farms as can be seen in the pie charts below.

Range of Silage Crude Protein % in 2014
 
It’s a powerful reminder that nobody should rely on guess-work for determining silage Quality. Recommended concentrate supplementation rates for milking cow will vary by up to 3Kg per head per day for <60 DMD silages versus >70 DMD silages. 
Key point: We recommend testing all silage, each pit / cut of bales to accurately determine supplementation rates
