POWER2

Product catalog summary

Introduction to Power2 Feed Formulation
Power2 introduces a new generation of fish feed designed to neutralize the natural variations in raw materials, ensuring stable performance and predictable production. This approach focuses on net composition rather than gross composition, leading to efficient resource utilization and minimal nutrient loss.

Fish Growth and Nutrient Digestibility
Fish growth is influenced by the protein, energy, and micronutrient content of feed. However, not all nutrients are digestible, with approximately 10% of feed ending up as indigestible faeces. The digestibility of amino acids varies, making it crucial to understand the digestibility of each amino acid in different raw materials. Aller Aqua's trial station continuously tests raw materials to measure their effects on faeces consistency and fish appetite.

Testing Feeds for Nutrient Digestibility
Feed formulation based on fixed levels of digestible nutrients helps balance natural variations in raw materials. Digestibility testing can be conducted in vitro, in vivo with land animals, or in vivo with the target fish species. The testing process involves producing pilot-scale test feeds, feeding them to fish, collecting faeces, and analyzing nutrient content. This data helps build a comprehensive database for efficient feed formulation.

Appetite and Faeces Quality
Fish growth rate is linked to feed intake, making palatability an important factor. The selection of raw materials affects faeces structure, which is crucial for recirculating aquaculture systems (RAS). Testing includes assessing faeces quality to ensure effective removal from water systems.

Power2 Concept and Future of Feed Formulation
Power2 moves away from fixed declarations on datasheets and labels, focusing instead on stable performance. Future datasheets will note variations in crude protein, fat, fiber, and energy due to raw material differences. Continuous testing is essential to determine feed performance, with Power2 feeds offering high, stable, and predictable performance.

Conclusion
Power2 feeds, including Aller Gold, Aller Vitamax, Aller Nordic, and Aller Arctic, are formulated for optimal nutrient utilization, high palatability, and compatibility with modern farming technology, ensuring the best water environment and farming results.

A NEW CONCEPT FOR FEED FORMULATION NUTRIENT DIGESTIBILITY LET’S GROW TOGETHER

FISH FEED AND GROWTH WITH POWER2 WE INTRODUCE A NEW GENERATION OF FEED. THE COMPOSITION OF THE FEEDS IS ADJUSTED TO NEUTRALISE THE NATURAL VARIATION OF THE RAW MATERIALS. NO SPECIFIC RAW MATERIAL WILL MAKE A FISH GROW. FISH GROW BASED ON THE CONTENTS OF THE RAW MATERIALS - SPECIFICALLY PROTEIN AND ENERGY, AS WELL AS MICRONUTRIENTS. Traditionally, feeds have been composed and sold in order to obtain a set declaration - a gross composition. However, the fish do not utilize all the contents. Part of the nutrients are indigestible, and thus not absorbed in the fish digestive system. These end up...

TESTING FEEDS FOR NUTRIENT DIGESTIBILITY FORMULATING FEEDS ACCORDING TO FIXED LEVELS OF DIGESTIBLE NUTRIENTS OUTBALANCES THE NATURAL AND UNAVOIDABLE VARIATIONS IN RAW MATERIALS AND IS A SIGNIFICANT PARAMETER IN ASSURING STABLE FEED PERFORMANCE ON A FISH FARM. 1. Test feeds are produced under pilot scale conditions. All feeds are identical, except from one being the reference feed and the remaining feeds each containing one specific raw material. All feeds contain an inert marker. Determining the digestibility of nutrients in fish feed can be done in three ways: 3. At the end of the test, both...

POWER2 FIXED DECLARATION ON DATA SHEETS AND LABELS IS HISTORY - FIXED PERFORMANCE IS THE FUTURE Traditionally the quality and potential in a feed has been evaluated from the declaration. For many farmers declarations and price lists have been the only tools for choosing feed. The performance of a feed can however not be determined from a declaration and consequently these tools have never been anything but indicative. These indications will not get any clearer in the future. Historically feed has been formulated to a specific declaration and the natural variance in the used raw materials have...
