Of course, the main determinant of how much protein you start with is grass maturity. Both energy and protein fall as grass matures. As a result, silages at 70 or 65 D-value have protein levels typically 16% or 12% respectively.
If you have to fill this 4% gap with bought-in proteins, which all follow a soya price benchmark, the likely cost over a six-month winter could be as much as £8,000 for 200 cows at 8,000 litres/cow herd average.
By protecting more of what you harvest with OptiSile Extra, much of this can be saved. Incidentally, exactly the same principles apply to energy.
As raw material and freight continue to soar and with sustainability pressure building, protecting home grown feed stocks by choosing OptiSile ‘rapi-ferm’ inoculant is an essential component in helping to produce more milk from within the farm boundary by reducing bought in feed and helping your environmental footprint.
