After the preparation of the LCI the next stage in an LCA study is the life cycle impact assessment LCIA in which a series of models are used to estimate the impacts of resource depletion and waste generation.
LCA is a particularly powerful tool because it considers different impacts at once and merges all models into one coherent model so that a holistic. Dairy Sector A Life Cycle Assessment. Greenhouse Gas Emissions from the Dairy Sector A Life Cycle Assessment A report prepared by.

The designations employed and the presentation of material in this information product do not imply the expression of any opinion whatsoever on the part. Dairy production has a substantial environmental impact.
Currently most studies analysing the environmental burdens of milk production employ attributional Life Cycle Assessment LCA for cradle to farm-gate analysis of dairy systems. This approach calculates environmental footprints per kg fat and protein corrected milk FPCM. However milk and beef production are inherently.
The life cycle of a dairy cow is predictable and therefore can largely be managed with scheduled activities. For dairy farms that maintain a seasonal calving pattern with cows calving every twelve months the life cycle of the cow can be linked to an annual calendar of management events. However maintaining a 12-month calving interval poses several reproductive challenges and.
