Abstract

The shortcomings of determining the net energy content of feeds using difference trials are discussed. In trials with low-quality hay and silage, experimental error is large and it is suggested that the SE of one lot of hay or silage should be determined by difference and that maintenance trials should be performed with the above roughage in alternation with other roughages of poor quality, using non-lactating cows for the difference trials and lactating cows for the maintenance trials. The SE of the poor quality feeds can then be calculated.-R.B.
