It’s supposed to reduce cow farts. See e.g. https://www.euronews.com/green/2021/09/24/seaweed-to-cow-feed-why-is-sweden-building-the-world-s-largest-algae-facto

  We had explained yet here why this point of view is incomplete and wrong. If you provide antibiotics to a cow they probably will fart less, but also will grow poorly and will not produce good milk. Cows need their gut bacteria to liberate the nutrients in their food and remain healthy. Many macroalgae have antibiotics as chemical defenses so feeding cows with it is the same as feeding cows antibiotics. Its ability to eat cellulose will be destroyed. Even worse, this algae they evolved to use chemical defenses, so they grow slowly and only in a narrow ring around the continents. If some thing grows slowly, to harvest it at large amounts will destroy the resource in no time. Is a totally non-scalable plan. Feeding cows with Chondrus is a false solution. If we try this path I predict that we will soon hit a dead end. Feeding cows with Spirulina would fall into a different situation and maybe could work (but Spirulina is contaminated and spoiled easily).
