Methane gas to feed protein producer, Calysta, says its protein product, branded as FeedKind, has been approved for use as an ingredient in organic systems for feed by Organic Farmers & Growers (OF&G), the UK organic certification control body.
Grant-funded feeding trials assess potential methane mitigates and use of additive nitrates and bismuth subsalicylate in high-sulfur cattle feeds, says researcher.
California based biotechnology company, Calysta, says it has produced sufficient quantity of its novel protein, FeedKind, to be able to ship samples for testing worldwide.
Researchers are looking to generate protein for animal feed from biogas production sited on pig farms, reducing dependency on imported proteins like soy.
This week saw US firm, Calysta, formally open a UK pilot plant to produce its ‘protein-rich biomass’ for fish feed as an alternative to fishmeal and soymeal.

The sustainability profile of Calysta’s methane gas to feed protein, FeedKind, could be bumped up if its production involved the use of biogas, but its land and water resource saving metrics are solid, finds a report from UK agency, the Carbon Trust.
Danish company, UniBio, has sold the entire production from its future methane gas to feed protein production facilities to Danish animal feed manufacturer, Vestjyllands Andel.
The compound feed industry needs to get behind initiatives that foster precision feeding on small farms in developing markets to help optimize use of on-farm ingredients backed by commercial feed mixes to plug nutritional gaps, says the FAO.
Nutritional modeling systems developed by a US university to lower feed costs are now being used to reduce methane emissions from cattle feed, says the researcher behind the project.
Researchers from Bangor University, UK, warn that diverting fodder crops to farm-scale anaerobic digestion in the UK could put pressure on animal feed supply and cause damage to the environment through land use displacement.
Nutrition and feeding approaches may be able to lower enteric methane in dairy production by up to 15%, but rumen modifiers have had very little success in terms of sustained methane reductions without compromising milk production, found a meta-analysis.
