Abstract

Locally produced feed is frequently being promoted as a way to reduce climate impact from animal production. No need for long-distance transports and avoidance of soy meal and palm kernel meal, feeds which are drivers in the on-going agricultural expansion on natural land, are seen as the major advantages for local feeds. This study has compared five different Swedish dairy cow feed rations: one typical Swedish dairy cow feed, three different locally produced [one with the ethanol by-product DDGS, one with more and better silage and one with rapeseed, peas and clover/grass silage] and one with maize silage and dried beet pulp. The feeds are all designed to support a production of 9000 kg ECM milk annually. The method used was life cycle assessment, taking into account: farming, including production of input materials and loss of carbon due to land transformation (but not cleared biomass) for soybean cultivation; feed production (e.g., extraction of rape seed oil); long-distance and regional transports. The purpose of this study was to analyze the contribution of each feed ingredient to the total greenhouse gas emissions for feed production
