Standardising the predic/ve equa/ons to determine energy density in pet food - EN 16967: 2017 - Dr Thomas Brenten Royal Canin Nutri/on & Analy/cal Science Group FEDIAF 1

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

FEDIAF – Codes of good prac/ces Task Force

What has happened? Mandate: 2013 2014 + 07/2017

Why do we need such an EU standard? The regulatory framework. Regula?on (EC) Direc/ve (EC) 767/2009 2008/38 Art. 17.1(b) Mandatory nutri?onal Mandatory : compliance criteria Feeding guides AND AND Voluntary energy Mandatory energy declarar?on declara?on for: - Convalescene Diets - Obesity Diets 5

Why do we need such an EU standard? The pet perspec/ve. Nutrient Energy intake PET requirement (Feeding guide!) Dog: 132/110/95 kcal / kg BW 0.75 Cat: 75 /100 kcal / kg BW 0.67 PARNUTS Feeding trial DIET Nutrient profile in diet Revision or (Compliance criteria) 2008/38/EC PME calcula/on

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 Ge ingested (kcal/kg) Ge excreted (kcal/kg) Calorimeter bomb DE (kcal/kg) = GE ingested – GE excreted ME (kcal/kg) = DE – urine loss

Why do we need such an EU standard? The principles. Well established & widely used: calcula?on method Crude Crude Crude NFE + protein fat fibre (calculated) Declared Analysed PREDICTIVE EQUATION values values Predicted Metabolisable Energy

Why do we need such an EU standard? The regulatory reality. Atwater Modified Atwater Modifica/ons of the modified Atwater

How was the EU standard established? The data perspec/ve. Modified Atwater NRC CF Atwater* (2006) Wet Dry Dog/ Cat Devia/on from experimental determina/on D ata (547) submiaed by FEDIAF member companies) * Recommended for highly diges?ble special products such as milk subs?tutes or diets for enteral nutri?on

How was the EU standard established? Results. Prepared Pet Food NRC CF (2006)

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?

Conclusion • 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

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 - THANK YOU! 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.
