ANNEX VIIU.K.METHOD OF CALCULATING THE ENERGY VALUE OF POULTRYFEED
1.Method of calculation and expression of energy valueU.K.
The energy value of compound poultry feed must be calculated in accordance with the formula set out below on the basis of the percentages of certain analytical components of the feed. This value is to be expressed in megajoules (MJ) of metabolisable energy (ME), corrected for nitrogen, per kilogram of compound feed:
MJ/kg of ME = 0,1551 × % crude protein + 0,3431 × % crude fat + 0,1669 × % starch + 0,1301 × % total sugar (expressed as sucrose).
2.Tolerances applicable to declared valuesU.K.
If the official inspection reveals a discrepancy (increased or reduced energy value of the feed) between the result of the inspection and the declared energy value, a minimum tolerance of 0,4 MJ/kg of ME shall be permitted.
3.Expression of resultU.K.
After application of the above formula, the result obtained must be given to one decimal place.
4.Sampling and analysis methodsU.K.
Sampling of the compound feed and determination of the content of analytical components indicated in the method of calculation must be performed in accordance with the F1... sampling methods and analysis methods for the official control of feed respectively.
