Fishmeal and Fish Oil Replacement
DHA Natur™
DHA Natur™ is a dried algae that contains docosahexaenoic acid (DHA). It is a highly concentrated, vegetable-based DHA omega-3 source. DHA Natur has been developed from heterotrophic algae through advanced fermentation technology. DHA Natur is produced from a highly controlled production system. It is a perfect choice for salmon and trout production, and can be applied to other facets of aquaculture diets.
Lecithin’s phospholipids content makes it a functional ingredient and an important source of phosphorus, choline and energy. In addition, its emulsification properties aid in the absorption of fats and fat-soluble vitamins. Soy lecithin is a mixture of phospholipids obtained from soybean oil through the degumming process. It typically contains phosphatidylcholine (PC) 23 percent, phosphatidylethanolamine (PI) 14 percent, phosphatidic acid (PA) 8 percent and other lipids.
Vegetable Oils (Corn, Soybean, Flax & Canola)
Vegetable oil is obtained by extracting the oil from seeds commonly processed for edible use. Corn and soybean oil provide the main sources of vegetable oil available for livestock. Both corn (55 percent) and soybean (53 percent) oil contain high amounts of the essential fatty acid linoleic acid. These oils, primarily used to add energy to the diet, provide a high amount of unsaturated fatty acids. Vegetable oil supplies slightly more energy than animal fats and may be used to reduce dustiness in feeds. Another vegetable oil, flax oil, is starting to receive more interest because of its high alpha-linolenic acid content (ALA, 18:3, w-3). ALA, is a polyunsaturated omega-3 fatty acid.
Soy Protein Concentrates
Soy protein concentrate is a consistent, high-quality vegetable protein with low allergenicity characteristics. Manufactured from soy flakes through a unique combination of processing steps that remove the soluble sugars and anti-nutritional factors, soy protein concentrate serves as an excellent protein source aquaculture diets. Its high protein content (65 percent crude protein) and excellent amino acid profile make it an ideal replacement protein for fish meal. Soy protein concentrate is available in both powdered and granular forms.
