FEDIAF – Facts & Figures

• Established in 1970
• Represen/ng the pet food industry in 21 European

countries via 16 na/onal or regional pet food industry associa/ons with round 650 member companies

• Being the competent partner for the EU ins/tu/ons in

all legisla/ve, poli/cal and technical aspects concerning the pet food industry

• Aiming at a legisla/ve framework for the produc/on of safe,

nutri/ous and palatable pet food

Why do we need such an EU standard? The regulatory framework.

Direc/ve (EC) 2008/38 Regula?on (EC) 767/2009

• Art. 17.1(b)

Mandatory energy declara?on for:

• Convalescene Diets
• Obesity Diets

Voluntary energy declarar?on Mandatory: Feeding guides AND Mandatory nutri?onal compliance criteria AND

Nutrient profile in diet (Compliance criteria) Nutrient requirement Energy intake (Feeding guide!)

Why do we need such an EU standard? The principles.

Gold Standard: Feeding trials

BUT: labour and cost intensive! Quantity of food ingested x GE food Quantity of feces excreted x GE feces

Geexcreted (kcal/kg) Geingested (kcal/kg)

Calorimeter bomb

DE (kcal/kg) = GEingested – GE excreted ME (kcal/kg) = DE – urine loss

Why do we need such an EU standard? The principles.

What does that mean for the industry? Common ques/ons.

• Do we have to declare energy density now on all products?
• Is it mandatory to use this equa/on?
• Can we s/ll do feeding trials?
• Do we have to men/on the method on pack, i.e.

in-vivo or CEN?

• What to do with products with > 8% crude fiber?
• Will there be changes in tolerances?

• The accurate determina?on of energy content in pet food is crucial

for formula?ng appropriate diets for cats and dogs as well as the corresponding instruc?ons for proper use.

• The equa?ons in the CEN standard cons?tute simple tools to be

used by manufacturers and control authori?es to calculate ME.

• This represents a good and robust compromise between accuracy

and prac?cability to overcome the difficul?es of feeding trials

• Dies ist ein Typoblindtext. An ihm kann man sehen, ob alle Buchstaben

da sind und wie sie aussehen. Manchmal benutzt man Worte wie Hamburgefonts, Rafgenduks oder Handgloves, um Schrihen zu testen.

• Manchmal Sätze, die alle Buchstaben des Alphabets enthalten -

man nennt diese Sätze »Pangrams«. Sehr bekannt ist dieser: The quick brown fox jumps over the lazy old dog.

• Oh werden in Typoblindtexte auch fremdsprachige Satzteile eingebaut,

um die Wirkung in anderen Sprachen zu testen. The quick brown fox jumps over the lazy old dog.
