SCHEDULE 9METHOD OF CALCULATING THE ENERGY VALUE OF COMPOUND FEEDS

Schedule 1, paragraph 9 and 18(1)(e)

The energy value of compound poultry, ruminant and pig feeds and feeding stuffs intended for particular nutritional purposes for cats and dogs shall be calculated in accordance with the formulae set out below on the basis of the percentages of certain analytical components of the feed or food. After application of these formulae, the results shall be given to one decimal place.

Poultry feeds: megajoules (MJ) of metabolisable energy (ME), nitrogen corrected, per kilogram of compound feed.

MJ of ME/kg of feed = 0.1551 × % protein27 + 0.3431 × % oil28 × 0.1669 × % starch29 + 0.1301 × % total sugar (expressed as sucrose)30.

Ruminant feeds: megajoules (MJ) of metabolisable energy (ME) per kilogram of dry matter in the compound feed.

MJ of ME/kg of dry matter = 0.14 × % Neutral detergent Cellulase plus Gamanase Digestibility31 + 0.25 × % oil28.

Pig feeds: megajoules (MJ) of digestible energy (DE) per kilogram of dry matter in the compound feed.

MJ of DE/kg of dry matter = 17.47 + 0.079 × % protein27 + 0.158 × % oil28 − 0.331 × % ash32 − 0.140 Neutral Detergent plus Amylase Fibre31.

Feeding stufls intended for particular rwtritional purposes for cats and dogs: megajoules (MJ) of metabolisable energy (ME) per kilogram of compound dog or cat food.

a

cat and dog foods with the exception of cat foods having a moisture content exceeding 14%:

  • MJ of ME/kg of food = 0.1464 × protein + 0.3556 × % oils and fats28 + 0.1464 × % nitrogen-free extract;

b

cat foods having a moisture content exceeding 14%:

  • MJ of ME/kg of cat food = (0.1632 × % protein + 0.3222 × % oils and fats33 + 0.1255 × % nitrogen-free extract) − 0.2092;

where in either case the percentage of nitrogen-free extract is calculated by subtracting from 100 the total of the percentages of moisture34, ash35, protein36, oils and fats33 and fibre37.

N.B. Where the results of analysis are to be given on a dry matter basis, this may be achieved by analysing either the dried material, or fresh material and correcting for the moisture content.
