Algae as dry fodder component is possible, but there is still much to be done to get it profitable. Thus, the cost of (dried) algae is high and a lot of energy is needed for processing.<\/p>\n
The brochure Opportunities for algae in animal feed are mentioned alongside these and other challenges as opportunities. So algae could potentially lead to an improvement in quality of meat, milk and eggs, algae are a source of omega fatty acids and they can be an alternative source of protein. Algae would put less burden on agricultural land than other feed.<\/p>\n
The brochure was written by Acrres (Wageningen UR) commissioned by NEVEDI and Nature & Environment under the Implementation Agenda for Sustainable Livestock (USO).<\/p>\n
The brochure states that algae have a high protein content. An alga contains 6 to 20% crude protein (dry matter), the rest of the species scores in this area between 43 and 73%. In soybean is about 37% crude protein, 14% in wheat and in corn 10%. From above, research shows “that algae to a share of 14 to 30% can be included in growing pigs feed without adverse effect on the animal performance ‘. For laying hens and broilers is respectively 12 and 17% algae.<\/p>\n
How digestible algae are actually, in view of nitrogen (N) and organic matter, has also been studied. In the report , the in vitro digestibility of the dried algae can be read what simulations of the stomach, the small and large intestine constituted of information. Further, on the basis of said feed optimization, Product typical prices.<\/p>\n
On digestibility: the organic matter of algal protein is in terms of digestibility between grass silage and soybean meal in. The digestibility of algal pulp is similar to that of grass silage. The nitrogen algae protein is more difficult to digest than that of soybean meal. The nitrogen of the pulp is somewhat more difficult to digest than that of grass silage.<\/p>\n
A recognized value for pure algae is \u20ac 33, – \/ 100 kg of dry product. For algae product dried excipient (see report for explanation) is \u20ac 16.50 \/ 100 kg and for the dried algae product with rice \u20ac 29, – \/ 100kg.<\/p>\n
The report also made several recommendations, including on drying temperature in relation to the N digestibility. With a view to saving energy possibly advantageous, having regard it is proposed to lower the temperature of 70\u00b0 C to 40\u00b0 C. The (as yet small) algae processing may incidentally involve much more than just the production of dried algae powder. In a short article in TNOTIME (Valori(e)tion of algae) is imaged what is involved in the processing of algae, which release waste products.<\/p>\n
The use of these residues is mentioned in the brochure of Acrres as an opportunity and focus.<\/p>\n","protected":false},"excerpt":{"rendered":"
