Increasing the ingredient flexibility of floating feeds

William Henry, Director of Technology and Research & Development, Extru-Tech, USA

The environment in which aquatic feeds being produced in Asia today has changed dramatically from even a few years ago. Now, more than ever, the ‘efficiency’ of production is critiqued at the same levels as ‘quality’ and ‘quantity’ of production.

This presentation will focus on the greatest input cost to most aquatic feed production process’s, and that is raw materials.

When reviewing the ‘Total Cost of Production’ for a specific type of feed, the raw material cost is typically in the range of 80 to 90%. Needless to say, a 10% savings on the raw materials will have a greater impact on production cost efficiency than most likely anywhere else in the process.

This strategy of increasing the process’ ingredient flexibility will be addressed from two primary angles. We will first discuss changes and enhancements in the core pieces of equipment in a typical extrusion process. And secondly, a review of proper/recommended process management directives will be presented.

Reassuring the value-chain as to the sustainability and purity of fishmeal and fish oil

Dr. Andrew Jackson, Technical Director, International Fishmeal and Fish Oil Organisation, U.K.

Two of the most important issues facing the fishmeal and fish oil industry in recent years has been the question of the sustainability of the fisheries providing the raw material and the purity of the products arriving at the feed mills. The industry is therefore looking at ways of reassuring the value-chain on these two critical issues. The best way to do this is using third-party audited schemes and the alternative schemes both developed and in the process of development will be discussed.

One scheme that is being initiated to address both these issues is the new IFFO Global Responsible Supply Standard. The development of this scheme will be discussed and how it assesses both fisheries and factories to provide the reassurance required.

Stabilizing formulation cost and performance of aquafeeds requires innovative approaches

Dr. Peter Coutteau, Business Development Manager Aquaculture, INVE Nutri-Ad, Belegium

In the livestock industry, a wide variety of feed additives are currently being investigated to improve cost-efficiency of animal nutrition. Organic acids, enzymes, probiotics, prebiotics, highly available minerals, essential oils and natural plant extracts are some alternatives to antibiotics without causing bacterial resistance that would have at least similar effects on growth and food conversion.

This active search for natural growth promoters is starting to extend into fish farming as consumer pressure is likely to ban antibiotics from production in most countries. Although the screening of these compounds for aquaculture has just started, promising results have been obtained with different species.

The presentation illustrates the development of a number of innovative feed additives to optimize the utilization efficiency of nutrients from traditional ingredients for aquaculture species
