Without a financial incentive to follow through (for example, a carbon tax on gassy animals) to offset the added cost of feed supplements, then most farms won't see the business justification (carbon footprint is largely externalized).
Only a small part of the animals feed needs to be seaweed and thankfully it is one of the easiest and fastest growing organisms on the planet. So it’s extremely cheap for the industry to adopt compared to losses related to carbon taxes and loss of market share.
Knowing a potential solution is not the same as solving a problem, unless you are performing an academic exercise.

Don't know how widely adopted this is.

Your underestimating the amount of food cows need to eat a day and likely overestimating global seaweed production in relation to even supply only 1% of cattle feed.
89 millions cows in the US alone eating eating 20+ pounds of food a day is 890,000 tons or nearly 325 million tons per year. That’s per day. Global production of seaweed was 358,200 tons in 2019. Only about 11% of what would be needed to be included in 1% of feed of every cow in America. And that wouldn’t leave any seaweed to be used for any of its other uses or the millions of other cows around the world.

I had debunked this yet a lot of times. This is a dead road and will fail. With the current data available is obvious that is a false solution.
I would strongly suggest to read the article with a critical mind
