Extract

The environmental and economic cost of concentrate protein ingredients is high, with the economic impact being especially important if these are certified free from genetically modified material. While reducing the crude protein (CP) content of the concentrate will reduce feed costs, animal performance is also likely to suffer (Mayne and Gordon, 1985). However it may be possible to maintain performance and yet reduce feed costs by reducing the protein content of the concentrate offered, with a simultaneous increase in concentrate feed levels. The current study was designed to examine the effects on animal performance of adopting this approach, and to quantify the ‘protein sparing’ effect of increasing the quantity of concentrate offered.
