As the agro‐industry produces considerable amounts of by‐products globally, it is acknowledged that there is a need to address the environmental issues related to their disposal and the resource competition between food for humans and feed for animals. The aim of this study was to explore, in vitro, the effects of various by‐products from the agro‐industry on rumen fermentation and methane emission. Samples were collected from various food processing industries, including red and green apple pomace (RAP, GAP), hempseed cake (HC), coffee hulls (CH), coffee grounds (CG), spent mushroom compost (SMC) and distiller's dried grains with solubles (DDGS). In doses of 100, 200 and 300 g kg−1, the tested by‐products were incubated in rumen fluid, where the by‐products replaced equal amounts of substrates.
