Confidence: Estimated. Canadian primary source for annual house-level consumption does not exist at this granularity โ Teagasc Ireland and Mississippi State Extension are flagged as international sources.
Operational reference for propane consumption in Ontario broiler, layer, and turkey barns. Brooding is the most propane-intensive event on any Southwestern Ontario livestock operation.
~50% of cycle fuel is consumed in the first week when chick brooding temperatures are highest (Mississippi State Extension, Modern Broiler House Heating Systems).
๐บ๐ธ Mississippi State Extension (flagged: US source โ used because no published Canadian equivalent at this granularity): "a single broiler house can use 3,000 to 5,000 gallons of propane in a year" โ 11,400โ19,000 L per house per year โ with "over 50 percent of the fuel consumed is during the first week alone when the highest temperatures are required."
๐ฎ๐ช Teagasc Ireland (flagged: international source, climatically and operationally closer to SW Ontario): "a standard 73m ร 18m 27,000-bird broiler house (without renewable energy installed) on average consumes 240โ270 megawatt hours (MWh) of heat energy/year. That's the same as 36,000โ40,000 litres of liquefied petroleum gas (LPG)."
Per US gallon of propane burned (Mississippi State Extension): 850 ftยณ/hr fresh air consumed; 92,000 BTU heat; 108 ftยณ COโ; 6.8 lbs (0.8 gal) water produced. A Wellington County broiler barn burning 300 USG in the first chick days adds โ240 gallons of water vapour to the brood chamber โ driving the ventilation rate that drives more propane consumption. This is the central economic problem of broiler heating.
| Operation | Annual propane (L) | Tank sizing typical |
|---|---|---|
| Single 25,000-bird broiler barn | 25,000โ40,000 | 1,000โ2,000 USWG |
| Two-barn broiler / 50,000 birds | 50,000โ80,000 | 4,000โ10,000 USWG |
| Three- to four-barn complex | 100,000โ250,000+ | 10,000โ30,000 USWG, multi-tank manifolded |
| Multi-barn turkey | 80,000โ250,000+ | 10,000โ30,000 USWG |
| Large layer with pullet brooding | 15,000โ60,000 | 2,000โ10,000 USWG |
Above ~9,300 L on-site, ECCC's E2 plan threshold is engaged โ see reg-eccc-e2-plan-propane-threshold.
NFACC's Requirement is observational: "Bird behaviour must be observed and necessary corrective action taken as soon as possible if birds are displaying signs of thermal discomfort." Detail in reg-nfacc-2016-poultry-code-brooding-temperature.
