Topic of the week

  • Algae Cake as a Protein Supplement

    When biodiesel and ethanol is extracted from the algae biomass, it loses its lipid and carbohydrates content .The remaining algae residue or cake containing proteins act as food-supplements for poultry and animals Will this algae cake be an effective protein source for livestock and cattle and also remain competitive in the market?

    It is depend on your protocol
    If you first remove oil from algae biomass its need high temperature that it will denature your proteins
    You have to first remove proteins than ethanol and finally oil

    HI THERE! I'VE BEEN INVOLVED WITH ALGAE CULTURE AND TESTS FOR ABOUT 2 YEARS NOW AND I'M FROM URUGUAY WHERE THE ECONOMY IS BASICALLY DRIVEN BY CATTLE INDUSTRY. WHAT I CAN SAY IS THAT YOU HAVE TO BE VERY CAREFUL IN SELECTING THE RIGHT ALGAE STRAIN TO GENERATE PROTEIN TO FEED CATTLE. IT IS PROVED THAT CATTLE DON'T LIKE THE SMELL OF MOST OF THE KNOWN ALGAE COMPOUNDS. THAT SAID, YOU CAN USE THAT PROTEIN FOR ANY KIND OF ANIMAL FOOD.

    As a protein cake for humans, it is achievable only by selected algae, so using Algae cake as a protein supplement for humans still long way to proof that all types of algae can be taken, but i think we can apply this idea to serve for birds and fish, these green cells also provide energy to B

    Oh, one more thing. We market some of our cattle as direct from the farm butcher beef. We have tried both grass fed and feedlot beef. Our customers all prefer the fed beef, not the grass beef. If a store is promoting grass fed beef and getting 50% more for it.....more power to them. Nobody ever said all the consumers are smart. I mean for an example they buy water in little plastic bottles that costs more than gasoline, gallon for gallon. And it is so doped up that 10 minutes after you drink 1 bottle you are thirsty again.

    Later,

    Larsyn, eggs are NOT raised by farmers. 'Egg farms' are owned
    by very large corporate business
    that deliever the feed to the corp. owned hens housed in corp. owned houses and the egg and house labor is contracted from the farmer who owns the land the egg houses are located on. The feed that goes into the hen house is 100% controled by the egg corp.
    There may be less than 1% of the eggs produced by "farmers" for the local farmers market and those hens may have a better diet.
    I respectively disagree with, "Notice none of these possibilities place algae directly to the consumer. They pass thru another unit first."

    My problem with this is IF the algae have retained something bad ie heavy metals, medicines,etc. then the consumer of this algae will serve as a "concentrator" of those posins and we will get a real big dose from eating the final graziers of 'dirty' algae.

    Cheers

    Sam eggs from cage raised chickens color is controled by the farmer. By adding alfalfa to the feed they can darkin the yolk. Also adding marigold flowers gives very orange yolks. Algae as a cattle feed may provide simular results to grass feed beef. This could make feed lots very interested in Algae. Grass feed beef is almost 50% higher in the store. Algae as a fertilizer is very interesting thus returning a farms waste products back to the land. Notice none of these possiblities place algae directly to the consumer. they pass thru another unit first.

    Just how 'good' is DAM? (Dried Algae Meal) What does the amino acid balance look like?

    Will this 'green meal' turn the yolks of eggs GREEN? Or will it improve the golden yellow color
    of the egg yolk?
    Range raised hens have better looking eggs then caged raised hens. This is probably due to the fact that some of the range raised hens eat green plant material.

    The algae cake will be priced according to its worth. It will be in competition with soybean oil meal and cotton seed meal etc.

    I don't come from a biology or chemistry background so correct me if I am wrong but it seems to me that animal feed is just one of the many off shots of this meal.Through fermentation there are other opportunities such as gas or alcohol based fuels (Methanol, Ethanol, Jet Fuel, Methane and even Hydrogen and CO2 recovery). In addition to the feed I believe you can also develop fertilizer and other more specialized items. I am interested in understanding what is the best mix because from what I have read, the strains of algae that are good for oil may not be good as a meal for specific items or products. I still have to look into market pricing, but if someone can provide some recognized prices I would think that would benefit several people on this list
