Egg protein is the standard by which all other protein ingredients are measured. The application of quality egg products goes beyond terrestrial species – what’s nutritious on land is nutritious in water!
IsoNova® is the manufacturer of egg products for use in aquaculture feed. IsoNova® has multiple production facilities spread throughout the United States that help ensure continuity of supply for even the largest customer. As the only manufacturer whose single focus is egg, IsoNova® offers value-added egg products that meet the exacting needs of aquaculture feed formulators and customers.
With its powerful nutritional package, the egg is uniquely suited for aquaculture feeds. It can enhance the sustainability profile of shrimp feed, fish feed, and salmon feed while also providing consumers with a recognizable and easy-to-understand food narrative for animal feed. In addition, when evaluated on a cost-in-use basis, eggs can be exceedingly cost effective when compared to alternative ingredients. They are a rich source of the more expensive components in aquaculture feeds: protein, energy, cholesterol, and phospholipids.
Based on information derived from National Research Council publications, the amino acid profile of egg protein better fulfills the needs of many fish and shrimp species when compared to most staple ingredients used in aquaculture feeds today. Eggs are well positioned to become a staple nutrient source in aquaculture diets.
Eggs complement the unique dietary needs of shrimp, naturally supplying high levels of cholesterol and phospholipids for optimum health and growth. In shrimp feed that relies on the supplementation of dietary cholesterol, phospholipids, or both, eggs can potentially help you spare a significant amount of fishmeal, cholesterol, and phospholipids. It is important to monitor the dietary lipid content of shrimp feed when formulating with eggs, however, and ensure they remain within acceptable ranges for shrimp feeds.
Current industry trends have many formulators replacing fishmeal with soybean meal, requiring a rebalancing of the dietary essential amino acid profile of their product. Egg product presents a useful fishmeal-free complement because egg protein is particularly rich in sulfur amino acids (methionine and cysteine), which are limited in quantity in soybean meal. In addition, the saturated fat content in eggs can help satisfy the statutory saturated fat needs of many fish species, which cannot be met with many plant-based oils or fish oil. Don’t compromise when it comes to your product’s nutritional profile.
Eggs are strikingly well suited to meeting the dietary needs of species that require high dietary protein and energy levels, including salmon and trout. The amino acid profile of egg satisfies the dietary demands of salmon, they are a net dietary protein contributor in these high-protein feeds, and they’re dense in metabolizable energy. In addition, egg product contains up to 80 percent less ash compared to fishmeal and poultry byproduct meal. It’s a natural fit for salmon feed.
