Crimson seaweeds are a well known weight loss plan complement to manage fatulence amongst ruminants–animals resembling cows, buffalos, sheep and deer–that feed on grass. When the grass breaks down of their abdomen, the fermentation course of produces methane.
Methane is a significant greenhouse fuel (GHG) that contributes to local weather change. About 30% of the planet’s methane manufacturing comes from cattle. A single cow can burp out 99 kg of methane yearly.
India is dwelling to 303 million cattle (19.5% of the worldwide cattle inhabitants, the world’s largest), 112 million buffalos (54.6% of the worldwide buffalo inhabitants), 150 million goats and 75 million sheep, in accordance with the ministry of animal husbandry and dairying.
The federal government plans to deal with this downside by including purple seaweed, which is wealthy in protein and located in abundance alongside the nation’s 7,600km shoreline, to cattle feed.
The event assumes significance on condition that livestock emissions from burps and manure account for round a 3rd of methane emissions.
This additionally comes towards the backdrop of the UN Framework Conference on Local weather Change’s (UNFCCC’s) 198 nations agreeing to submit their subsequent spherical of nationwide local weather motion plans—legitimate till 2030—by February or earlier than the subsequent large local weather summit in Brazil subsequent 12 months.
“Seaweed at current is just not a significant supply of animal feed and fodder, and DDGS (distiller’s dried grains with solubles) has a toxin difficulty. There’s a variant of purple seaweed that has some dietary worth and a few impact on methane emissions, and we’re planning to incorporate it to cattle feed. It’s a nascent factor,” one of many officers stated.
“This shall be an addition to the present feed.”

Seaweeds have been utilized as livestock feed for hundreds of years, with renewed curiosity for the reason that Sixties after Norway started producing seaweed meal from kelp.
Seaweeds are priceless various feeds, primarily due to their wealthy dietary content material, together with natural supply of chelated micro-minerals, complicated carbohydrates with prebiotic properties and polyunsaturated fatty acids.
The spokesperson of the animal husbandry and dairying ministry confirmed that the ministry is taking a look at seaweed as a possible supply of livestock feed.
“Given the 60-70% improve in demand of animal merchandise by 2050, livestock farming is predicted to face a big problem in assembly feed calls for,” the spokesperson stated.
“This problem is compounded by land degradation, food-fuel-feed competitors, inhabitants progress, water shortage and ongoing local weather change. Increasing the feed useful resource base by way of the identification of novel feeds shall be essential for the sustainable growth of the livestock sector,” the ministry spokesperson added.

“Integrating seaweed into livestock diets is not going to solely deal with environmental sustainability but additionally align with client demand for extra eco-friendly farming practices.”
The opposite official stated they don’t seem to be certain of how a lot amount shall be protected to be given to animals. “Should you give slightly greater than 5%, animals get sick. So, we’re figuring out which kind it may very well be given to livestock animals, the amount and the way a lot impact it’ll have on methane emissions,” the official stated.
“As a part of the plan, companies like Kochi College are researching on it in collaboration with some others,” the official added.
“We’ve completely different breeds of cattle in India; some are of international origin. The impression is just not going to be comparable in all of the breeds. Generalizing seaweed decreasing methane emission by 20-30% is just not right. These are the preliminary levels of analysis being achieved, and I have to have extra complete analysis earlier than we begin doing large-scale feeding of seaweed to cattle,” Chandra Bhushan, CEO of Worldwide Discussion board for Atmosphere, Sustainability & Expertise (iForest) stated.
“We even have to take a look at economics as a result of our cattle are largely free vary and never like American or European that are in ranches,” Bhushan added.
NDDB is exploring prospects of collaborating with Central Salt & Marine Chemical substances Analysis Institute (CSMCRI) and Gujarat Life Sciences (GLS), in order that algal formulations or their extracts could be recognized for his or her methane mitigation potential.
