Seaweeds include brown algae (Phaeophyceae), red algae (Rhodophyceae) and green algae (Chlorophyceae). Seaweeds are valuable alternative feeds for livestock, mostly as sources of valuable nutrients, notably chelated micro-minerals, the availability of which is higher than that of inorganic ones. Brown algae are of lesser nutritional value than red and green algae, due to their lower protein content and higher mineral content; however brown algae contain a number of bioactive compounds. The use of algae as animal feed is promising, as they are sustainable, contain lots of protein and result in more omega 3 in eggs and milk. There is also evidence that they help young cattle grow better. A research in Netherland shows the benefits of algae in feed; Processing algae in animal feed is probably not the first thing that occurs to producers, but the green stuff seems highly appropriate for this purpose. Studies show that using algae as animal feed ensures better quality eggs, milk and possibly meat, and that it boosts growth in piglets, chickens and lambs, among others. "In addition, algae are rich in protein," says Wageningen UR algae expert Rommie van der Weide. "This makes them an interesting alternative to soy, which often has to be transported across long distances – from South America. Algae are produced in photo bioreactors and open ponds, making as much use as possible of the residue streams from a biogas plant. The algae grown here are used in animal feed, mineral licks and a feed supplement for horses. Source;all about feed.
