The following tables break down the price of the various feed ingredients. Although there may be significant changes in prices as the winter feeding period progresses, the following can be used as a basis for discussion. There may also be some difference in price between feed sources.  The first table shows the price/tonne, price/kg of product, and price/kg of actual protein or protein equivalent. The second table shows the price/tonne, price/kg of product and price/kg of TDN for various energy supplements. Products marked by * contain added minerals and vitamins and this will have a small effect on overall cost.
