The product is an Asparagopsis-based seaweed oil extract formulated by Hawaii-based start-up Symbrosia, which at present markets a freeze-dried seaweed feed additive.
Asparagopsis, a kind of crimson seaweed, has been discovered to scale back livestock methane emissions by as much as 80%, although analysis has discovered variations in its efficacy in terms of ruminants. For instance, a 2019 research discovered that an Asparagopsis specie used as a feed additive decreased methane manufacturing and depth by over 26% with out affecting milk yield or feed consumption, rising to over 60% and 42% respectively when the dose was doubled. (See ‘sources’ beneath for extra data.)
Symbrosia’s current product, SeaGraze, is comprised of Asparagopsis taxiformis, which the corporate claims can obtain double the methane discount of its opponents with the identical quantity of product inclusion. However SeaGraze is produced via freeze-drying, an energy-intensive course of that includes dehydration to protect the product’s heat-sensitive compounds.
A research with Cornell College’s Faculty of Agriculture and Life Sciences (Cornell CALS), supported by Danone North America, is aiming to show the effectiveness of an Asparagopsis-based seaweed oil extract in contrast with the corporate’s current fare.
Symbrosia defined that oil absorbs the compounds present in seaweed successfully, thus eradicating the necessity for drying. On this kind, the product can be anticipated to extend the extent of bioactive transference and solubility.
Utilizing the brand new methodology would additionally keep extra of the necessary compounds and vitamins. If the research is profitable, the oil will probably be made commercially out there – which is the place Danone’s curiosity lies.
Requested what potential the corporate sees on this product, a spokesperson for Danone North America instructed DairyReporter: “As part of our regenerative agriculture technique and Danone Influence Journey to scale back GHG and methane from our provide chain, we’re actively working with farming companions to assist assess and implement new instruments and applied sciences which might be each useful to the farm and create improved environmental efficiency. Symbrosia’s merchandise are part of a broader technique to deliver as many instruments to our farming community as doable.
“We anticipate that Cornell’s experience will assist affirm optimistic impacts on methane emissions, animal welfare and total milk high quality in order that this product could be an choice for industrial farms as quickly as sensible.”
The research has been designed by Joseph McFadden, affiliate professor of dairy cattle biology, whose analysis group additionally leads the event of the Cornell Accelerating Livestock Improvements for Sustainability program. DairyReporter perceive that it’s a university-based trial with experiments happening with a subset of the Cornell Dairy herd. The sequence of experiments that may assess the impression of Bromoform on power utilization in dairy cattle in addition to security and efficacy will happen over the subsequent 1-2 years.
