We investigated the protein value of 8 different seaweed species in dairy cows.
- class="label">•
The seaweeds collected in spring had higher nutritive and protein values as compared to autumn samples.

Porphyra and Ulva can supply a high amount of digestible protein to the small intestine.
- class="label">•
Acrosiphonia, Alaria and Laminaria can supply high rumen degradable protein.

Mastocarpus and Palmaria both can supply equal amounts of protein to the rumen and intestine.
