LCI Method PrincipleAttributional
LCI Principles DeviationsAttributional LCI methods used
LCI Method ApproachesAllocation - gross calorific value
LCI Method DeviationsAllocation by gross chemical content; 91.44% to eggs, 8.56% to spent hens.
Modelling Constants99.1% of spent hens to human consumption and animal feed rendering, 0.9% of spent hens considered as waste due to incineration and composting; 100% of mortalities considered as waste due to incineration and composting; Manure storage: 100% covered dry pile.
Modelling Constant DeviationsNA
Data Cutoff/Completeness Principles Infrastructure and farm machinery not considered; Other exclusions are antibiotics, cleaners, and enteric fermentation for poultry; Emissions related to burning of industrial machinery not included.
Deviations from Cutoff/Completeness PrinciplesNA
Data Selection/Combination PrinciplesRepresenting data from 13 reporting facilities representing 3128791 dozen eggs sold.
Deviations from Selection/Combination PrinciplesNA
Data Treatment and Extrapolation PrinciplesStandard excretion rate was assumed for manure production, scaled to reported feed conversion ratios. Half of manure produced was assumed to be deposited directly onto range land.
Deviations from Treatment and Extrapolation PrinciplesNA
Supply Coverage20.47%
Dataset Use AdviceOnly used as a representation of average Canadian egg production from free range layer facilities.
