5.Correlation ofAnnexesIIIandIV.PARTII,Birdswithoutoffals.
A
Duringthediscussions onRegulation (EEC)No2967/76atCouncillevel,\
thecoefficients 3,5(chickens)and3,0(hensandcocks)wereinserted
'intoAnnexIVtocoverthecaseofbirdsforwhichtheexperimental
materialtreateddidnotincludeoffals.Inattempting tocomparethese
coefficients withthoseusedinAnnexIII,twobasicdifficulties arise:
(a)Theexperimental materialusedinStudy15,fromwhichtheregression
equations inAnnexIIIwerederived,includedoffals.
(b)Nodataareavailable totheCommission onthetestingofthecoeffi­
cients3,5a11®'-3,0againstbirdswithaknownwaterabsorption .Such
testscouldbeimportant inindicating changesintheconfidence limits
oftheregression betweenbirdsprepared dryandthosesubjected to
immersion inwater(seeAnnextable1,hensandcocks,forexample).
Abriefstudyofthedatasupplied byDr.Woltersdorf revealsthatthe
coefficients of3,5and.3,0whicharenowinAnnexIVarethemeansofthe
individual ratiosoffat-freeedibleparts(dryweight)tophysiological
water,forchickens (No=40)andhens(Nom50)respectively .Asthesetwo
variables arehighlycorrelated (Annexta.blell),amoreappropriate mode
ofexpression wouldbebyregression equations .Theeffectofusingre­
gression equations todetermine thephysiological watercontent,insteadof
themeancoefficient ,isequivalent toabout+3^of(dry)carcaseweight
forchickensand+5,75$forhens,withaconsiderable variation evidont
betweenlightarjdheavycarcases (Annextable12).
Inordertoattempt.acomparison betweenthemethodinAnnexIVforbirds

expressed inrelation tothecarcaseweightpluswateraddedunderAnnexIII.
Onceagain,thismeanresultdisguises considerable variation according to
thecarcaseweightconcerned .Itshouldbenotedthatthereisanassumption
thattheconfidence limitswouldbethesameasfordrypreparedbirds,

Inordertodemonstrate theeffectofusingthemeancoefficient under
AnnexIV,insteadofthemoreappropriate regression equation ,similarcal­
culations werecarried outandthedifference between Annexes IVandIII
became-4,29$ofthedrycarcaseweightor-3,87r>thecarcaseweight
pluswateraddedtinderAnnexIII,withwidevariation according tocarcase
weight.
Themainconclusions ofthisseriesofcalculations are:
(a)Forbirdswhereoffalsarenotincludedintheanalytical material,the
methodsdescribed inAnnexesIIIandIVofRegulation (i'EC)2967/76appear
tobereasonably wellcorrelated .
(b)Itisacondition ofthiscorrelation thatthephysiological watercal­
culatedinAnnexIVmustbeestimated byaregression equation ,rather
thanbyasimplecoefficient .
(c)Thelargelyhypothetical natureofthecalculations usedshouldbecon­
firmedbylaboratory testing,andparticularly againstbirdsofaknown
wateruptake.
Inordertohavethenecessary laboratory testscarriedout,theCommission
oftheE.E.C.hasalreadyrequestedthelaboratories ofKulmboch (W.Germoiiy )
andCopenhagen (Denmark)togivetheiragreement inprinciple tofurther
comparative worktoconfirmtheexactcorrelation betweenthemethodsin
