The New Breed philosphy on minerals is to analyse the on farm forages for minerals and then formualte a farm specific mineral. This allows us to get the correct balance of Macro and Trace elements for the on farm forages. We also take into account any straights or other non-mineralised feeds used in the diet. As well as balancing elements that are deficient we can also potentially save you money. For example if there is a good phophorous level in the silage then each 1% of phosphorous saved in the mineral will save £23/tonne. Once we have the formualtion of the required mineral, which we can formualte from our diet check programme, we then put the mineral specification out for quotation with our selected mineral suppliers to get the best deal for our customers.
Below are 2 tables. The first shows the current national position of 392 samples of Grass Silage analysed by Thomson and Joseph between 01/06/13 and 10/09/13. The New Breed Forage Mineral Analysis is done by Thomson and Joseph so our results are included in the mean figures. The second table shows the year on year figures of both Macro and Trace Elements, for 1st Cut Silages and the main changes between 2012 and 2013. Below the tables is a summary of the potential risk factors from this years silages.
• LATE START TO GRASS GROWING SEASON COUPLED WITH RAPID VEGETATIVE GROWTH RESULTS IN INCREASED POTASSIUM (+7%) AND LOWER CALCIUM (-8%).
• PHOSPHORUS MAINTAINED AT 2012 LEVELS DUE TO REDUCED CALCIUM.
• ALTHOUGH POTASSIUM IS HIGHER, CAB IS CLOSE TO 2012 VALUE.
• IDEAL WEATHER CONDITIONS AT GRASS HARVESTING HAS RESULTED IN A 25% REDUCTION IN SOIL CONTAMINATION.
• ESSENTIAL TRACE ELEMENTS ARE SIMILAR TO 2012 LEVELS.
• MOLYBDENUM REDUCED BY 10% DUE TO DRIER SOILS.
• IRON AND MOLYBDENUM ANTAGONISM TO COPPER AVAILABILITY IS REDUCED.
• HIGHER POTASSIUM AND CAB INCREASES RISK OF HYPOCALCAEMIA.
• LOWER SOIL CONTAMINATION WILL AID SILAGE FERMENTATION AND REDUCE COMPETITIVE PRESSURE FROM IRON ON ESSENTIAL TRACE ELEMENTS.
• LOWER MOLYBDENUM AND IRON REDUCES ANTAGONISTIC PRESSURE ON COPPER AVAILABILITY.
IT IS VERY IMPORTANT THAT YOU ARE AWARE OF THE EXTENT OF THE POTENTIAL PROBLEMS WITH YOUR SILAGE. NOT ALL SILAGES WILL BE THE SAME AND IT IS ESSENTIAL TO TAKE A FORAGE MINERAL ANALYSIS TO FORMULATE A BALANCED MINERAL SUPPLEMENT FOR YOUR FARM AND HERD.
