University of California researchers are feeding seaweed to dairy cows in an attempt to make cattle more climate-friendly.
UC Davis is studying whether adding small amounts of seaweed to cattle feed can help reduce their emissions of methane, a potent greenhouse gas that's released when cattle burp, pass gas or make manure.
In a study this past spring, researchers found methane emissions were reduced by more than 30 percent in a dozen Holstein cows that ate the ocean algae, which was mixed into their feed and sweetened with molasses to disguise the salty taste.

That was my thought. Of course, the purpose of the salt lick is to supply vitamins(?) and minerals that may be missing in their food, but seaweed should be good for that also. And if they're going to go to something just because it tastes salty, why would you need to disguise the taste of salt?
OTOH, my grandfather always mixed a bit of molasses into the alfalfa that he fed his dairy cattle. I don't know why. But it's worth noting that raw molasses is not only high in sugar, it's also high in various minerals (basically, everything durable that they wash out of the sugar in the process of making it white).

If you need it to be a regular part of the idet, blended in so that it's generally present in the rumen, then a salt lick won't do it.
Any given cow might go a week or more between significant goes at the salt lick.
