The numbers I often cite are for the US market: 94.8 million head of cattle * 25 pounds dry weight * .01 = 23,700,000 pounds of AT per day or 11,850 tons.
You're right that we can break this down with more granularity between US beef cattle (31.8 million head requiring 3,975 tons AT at 25 dry weight pounds daily consumption), dairy (9.35 million head requiring 4,675 tons AT @ 50 dry weight pounds daily consumption), calves, etc. For these two markets, the total daily tonnage required is 8,650. There are cattle that don't fall into dairy or beef categories. For US cattle industry numbers and statistics, see: https://www.ncba.org/beefindustrystatistics.aspx
We should be careful we don't talk ourselves out of efforts that are good for the world simply because they're not a one-stop solution. If Good Algae can grow to address markets outside of the US, amazing, but we will start here. And I will champion those taking additional measures to combat the crisis facing our planet.

The mechanism is mostly understood, but not perfectly. Most people know that a cow has multiple stomachs. The second stomach is called a rumen. A cow chews it's cud (essentially big mashes of grass and grain, which a stomach cannot digest). This cud is passed through the first stomach and into the rumen, which contains beneficial, digestive bacteria. The bacteria in the rumen essentially ferment the cud and make compounds which can be digested in the subsequent stomaches. Unfortunately, methane is a natural byproduct of this process.
AT and a number of other algae contain very low amounts of a compound called bromoform. Bromoform in high amounts is toxic, but it's believed that bromoform in these trace amounts changes the chemical reaction being undertaken within the rumen such that methane is no longer a product. The result is a more efficient digestive process, essentially lending energy back to the cow. Easier digestion for cows seems to equal better health and immunity, increased length of heat, increased food conversion ratios and perhaps just happier cows. There is a possibility of interaction with additional trace nutrients and compounds in the algae as well, and this is being researched.
Something to note is that AT is not the only algae that reduces methane production in cattle. It is just, by far, the most efficient. And algae is not the only product which decreases methane in cattle, as well. Companies are marketing probiotics and small molecule methane inhibitors which do similar jobs, but again, AT is nearly twice as effective.

My company is currently working to grow Asparagopsis Taxiformis, here in the US, for this purpose.
I agree with comments that we have big issues to tackle in regards to methane sinks failing, such as permafrost, and there are things to be said about people moving en masse to plant based diets – but, the future will always be a mix of tomorrow and today. Many people will still eat beef, and we need to ensure we reduce the negative effects of raising cattle as much as possible. We need a giant, mixed bag of tricks working in unison to slow the warming we have caused over the last 100 years.
Luckily, current research is showing that – not only does AT nearly eliminate methane from the bovine digestive process entirely when supplementing between half and two percent of daily diet – we are seeing early indications in research of some amazing additional benefits – improved milk production, increased immunity, improved food conversion ratio (meaning you can feed cattle less and have them pack on more protein). Studies are not finalized, but what I have heard of them sounds very, very good.
My background is in tech (founded and exited a TechStars company and have had a career in software and hardware startups) and my colleagues are in marine biology and phycology (algae science). My hope is that by approaching this problem from the perspective of a fast-iterating startup, we can get this product to market faster than the traditional routes of academic timelines and federal funding sources this industry is used to.
