Cattle for slaughtering, live weight, Northern VIC {AU-VIC}| milk production, from cow | AusLCI, U

Unit process v00.00.000

Included processes: The inventory begins with the breeding, growing and maintenance of cattle in the State, Region, and Production System detailed, including pasture, feed inputs, supplements and energy use on farm. The system boundary ends at the farm gate with the production of cattle for sale in three classes - culled cattle (Cast For Age cows and bulls), prime cattle (heifers, feeder steers and finished steers) and weaner cattle (female and male). The direct emissions on the farm are also included. Excluded processes: Indirect land use change and soil organic carbon (SOC) fluxes are not included by default however the details of land use change and SOC flux for the region is included in parameters of the inventory. This inventory has been developed as with support from Australian Government through the National Landcare Programme Innovation Grants for the project ?AusAgLCI - enabling continual improvement of sustainability by life cycle impact assessment (INNOV-033)? which is was undertaken by CSIRO Agriculture and Life Cycle Strategies from 2014-2016. The inventory was updated in 2023 with support from Australian Government through the National Agriculture Traceability Grants Program for the project - "Equipping Australian agriculture with sustainability metrics (PRO-017538 )" Technology: Average Time period: 2018-2022, 5 years Version: 1.2 Record: Data entry by: Sandra Eady Tel: ; email: sandra@lifecycles.com.au; company:Lifecycles; Country: AU Generator: Generator/publicator: Sandra Eady Tel: ; email: sandra@lifecycles.com.au; company:Lifecycles; Country: AU
