Increasing the ingredient flexibility of floating feeds

noreply@blogger.com (Linx Conferences) — Mon, 10 Aug 2009 18:38:00 +0000

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

noreply@blogger.com (Linx Conferences) — Thu, 06 Aug 2009 18:47:00 +0000

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

noreply@blogger.com (Linx Conferences) — Thu, 06 Aug 2009 18:36:00 +0000

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

Extrusion of Micro Aquatic and Shrimp Feeds

noreply@blogger.com (Linx Conferences) — Sat, 01 Aug 2009 00:11:00 +0000

Joseph Kearns, Aquaculture Process Technology Manager, Wenger Manufacturing, USA

Production methods are reviewed for manufacturing of micro - or what is commonly referred to as starter feeds. Extrusions cooking in various formats are discussed with the technology involved for production of these feeds but also the ability to produce at increased production rate. Typical increase levels are in the three to five times range while allowing all the formulation advantages seen in extrusion of shrimp feeds.

The use of rendered animal products in aquaculture diets

noreply@blogger.com (Linx Conferences) — Thu, 30 Jul 2009 18:47:00 +0000

Geoff L. Allan, N.S.W. Department of Primary Industries. Port Stephens Fisheries Centre, Nelson Bay, Australia

Aquaculture remains the fastest growing food producing primary industry in the world. Of the approximately 52 million tonnes of production, about 16.3 million tonnes comprises species that are fed. Marine finfish are generally strictly carnivorous and most are fed on fishmeal-based, high protein diets (>45% protein) or even directly fed “trash fish”. Current production of fishmeal is stable, and the increases in demand have been met by diverting fishmeal from other animal feeds. However, future increases in aquaculture production will require alternative protein sources.

Increasing amounts of vegetable proteins are being used but for marine carnivores, a requirement for high dietary protein, driven mainly by an inability to tolerate high dietary carbohydrate, or effectively use either carbohydrate or lipid for energy, has restricted fishmeal replacement to date. However, rendered animal protein sources, such as poultry offal meal, meat and bone meal and blood meal products are excellent protein sources with no carbohydrates and few anti-nutrients. Approximately 12.5 million tones of rendered animal meals are available globally, roughly twice as much fishmeal as is available.

Data for digestibility and utilization of rendered animal products fed to a variety of carnivorous and omnivorous aquaculture species will be presented. Data for trout, red sea bream, tilapia and mud crabs from numerous research studies will be summarized and the potential for use of rendered products discussed. The data demonstrate that rendered animal meals can be excellent protein sources for aquaculture species, including carnivorous marine finfish.

Substantial replacement of fishmeal is possible, particularly with blends of alternative protein sources based on rendered animal meals.

Harvesting the benefits of grain application in Aquafeeds

noreply@blogger.com (Linx Conferences) — Mon, 27 Jul 2009 09:26:00 +0000

Dr. Brett Glencross, Stream Leader – Novel Feed Ingredients and Nutrition, CSIRO Marine and Atmospheric Research, Australia

To reduce risk associated with being too dependent on fish meal use in aquaculture feeds, considerable effort has been expended to assess and develop a range of grain protein meals as alternatives. However, the evaluation of such feed ingredients is crucial to their effective application in diets for aquaculture species. In evaluating ingredients for use in aquaculture feeds there are several important knowledge components that should be understood to enable the wise use of any particular ingredient in a feed formulation. The four primary knowledge components are: (1) Ingredient characterization, (2) Ingredient digestibilities, (3) Ingredient palatability, and (4) Nutrient utilization and/or interference of utilization.

In addition to these four key knowledge components, further details on ingredient functionality, gene and/or protein expression, the influence on immune status and organoleptic qualities are also important considerations.

Using this approach a range of feed grain resources have been evaluated in the diets of a range of aquaculture species. While there is no single ideal alternative many of the different feed grain resources offer sound potential when used in the right application. Indeed the judicious use of certain feed grain resources can confer significant nutritional and technical advantages to the feed design and management process.

Ingredients conference will have strong emphasis on aquafeed.

noreply@blogger.com (Linx Conferences) — Thu, 17 Jan 2008 02:32:00 +0000

The first Feed Ingredients and Additives Asia Pacific (FIAAP) conference will hold strong interest for the aquafeed sector, with several papers dealing specifically with aquafeed-related issues.

"All over the world we face increasing challenges to support the growth of aquaculture", said Colin Mair of Cormal Technology Ltd., U.K."One of these is the supply of the ingredients that provide our base protein and lipid requirements".

The environment we work in becomes increasingly challenging and we are faced with increasing demands for ‘natural’, ‘sustainable’, ‘ethical’ and ‘organic’ products. These demands in turn are driving us to source naturally derived ingredients with, it is hoped, an optimized delivery of nutritional performance plus added health benefits. It will be increasingly important to source ingredients that deliver the benefits of immune system stimulation, suppress auto-immune response, act as anti-bacterial and anti-viral agents, prevent or reduce cancers, deliver organically linked metals and pigments, and yet be sustainable, ethical and not create manufacturing problems. His presentation will look at some of these novel ingredients, at the claims made for them and at the processing issues that may result from their inclusion in diets.

Degussa Feed Additives has during the last years analysed a large number of fish meal samples from India and South America to give a better insight into the content of the first limiting amino acids. Huge differences in crude protein content as well as in the amino acid profile was found."It is evident that the content differs a lot and it is also clear that the amino acid content is not a constant ratio of crude protein", says Torben Madsen, Regional Technical Service Manager, Degussa (SEA) Pte. Ltd.

"Thus, if a constant factor for the amino acid content in crude protein is used the amino acid will in many cases be either above or below the expected level".

The variation in fish meal will of course also be reflected in the feed and the precise need for supplementation of the first limiting amino acids to meet the targets become more uncertain. Thus, as a consequence the needed safety margin to secure that the target is always met will increase. Delegates will learn how the results in this study clearly show that it is not enough only to look at the raw protein content. The focus should in stead be on the real content of amino acids in order to have the best information for the purchase decisions and feed optimization. However, this applies not only for fishmeal but also the other raw materials in the feed diet.

Protein and amino acids (AA) digestibility of poultry by-product meal (PBM), meat and bone meal (MBM), meal meal (MM), hydrolyzed feather meal (FeM), enzyme treated feather meal (ETFeM), blood meal (BM), and red blood cells (BC) measured from several commercially important fish and shrimp will be presented by Dr. Yu Yu, National Renderers Association, Inc., Hong Kong. The respective digestible protein and AA content from these protein meals will be compared for matching the requirements of the aquatic species and the cost-effectiveness measured from growth performance and feed utilization. Special emphasis will be on high-value carnivorous fish and shrimp.

Ingredient market intelligence is important to all sectors, especially in the current environment and the conference will provide insights into grain and soybean markets, fishmeal and oil and functional ingredients. Dr. Bob Swick, ASA-IM, Singapore will report on grain and oilseed trends and Scott Herbert, Omega Protein, will discuss marine oils and proteins.

Consulting Analyst with Frost & Sullivan, Sri Ganesh, will present a market overview of feed additives in Southeast Asia in terms of market size, unit value and volume. Pricing trends and the factors involved in influencing the prices of feed additives will also be discussed. The research is presented into several segmentations which includes feed amino acids, concentrating on methionine, lysine and tryptophan; feed acidifiers, and feed enzymes (non-starch polysaccharides and phytase).

Other topics of general interest to the feed industry but also of direct relevance to aquafeed include bacterial contamination of feed and feed ingredients: Dr Adam Smith, Anitox Ltd., will examine the prevalence of bacteria in animal feedingstuffs and their significance in the safety of the food chain, animal health and performance, while Mathieu Cortyl, Impextraco NV, will examine the problems and solutions associated with mycotoxin contamination in animal nutrition. Recent research indicates that the biotransformation of mycotoxins, using enzymatic preparations, gives promising results.

Some enzymes can transform the structure of mycotoxins such as deoxynivalenol or zearalenone, which are very difficult to bind efficiently. The products obtained from the reaction are less toxic compounds. "The application of such enzymatic transformations to the feed sector gives new opportunities because enzymes can have a specific action and their reaction, compared to binding, is not reversible", he said.

Because of the stong aquafeed content of this conference, delegates to Aquafeed Horizons Asia, can register for both conferences at a special rate.The FIAAP Conference takes place March 5, 2008 and Aquafeed Horizons on the following day, March 6, 2008, both at the Queen Sirikit National Convention Center, Bangkok, Thailand. These conferences will be held during VIctam Asia 2008 and the first feed ingredient conference, for the region, FIAAP '08.

Senior Thai Official to Open Strongly Technical Conference

noreply@blogger.com (Linx Conferences) — Tue, 04 Dec 2007 20:57:00 +0000

Dr. Juadee Pongmaneerat, senior expert in fishery product and inspection, Thai Department of Fisheries, to open strongly technical aquafeed conference

Cultivated marine shrimp have been an important source of protein in Thailand for many years and the country has been an exporter since 1991.

In 2005 and 2006 total production of marine shrimp was about 380,000 tons and 410,000 tons respectively, and in 2007, that figure is expected to reach over 500,000 tons. However, the Thailand has not escaped the devastating disease outbreaks suffered in shrimp farms world wide: WSSV, TSV and IHHNV have taken their toll.

This and the uncertainty of healthy brood stock supply, has seen the country make a dramatic shift from black tiger shrimp (P.Monodon) to the white shrimp (P. vannamei) , which today accounts for 95-98 per cent of production.
Other major aquacultured species in Thailand are sea bass, grouper, green muscle, blood clam, oyster, tilapia, catfish and giant fresh water prawn. There are 155 registered aquafeed mills in the country including premixed, supplemental feed, concentrate feed and complete feed.

Dr. Juadee Pongmaneerat, senior expert in fishery product and inspection, Department of Fisheries, Bangkok, Thailand will open the Aquafeed Horizons Asia Conference with an update of the country’s aquaculture and aquafeed status and explain the steps the Department of Fisheries has established to develop a strategy and policy for sustainable aquaculture and to enhance the safety and quality of aquatic food.

The conference will have a strong technical emphasis. Delegates will discover the very latest innovations in feed additives, such as pheromone attractants and palatability enhancers. Ingredients to add to the aquafeed formulator’s arsenal will be presented - from krill to insects, and novel feed supplements and neutraceuticals to promote performance and health in farmed fish and shrimp.

Many of these new ingredients will have an impact on the processing and this will be examined as part of the afternoon session, which will be devoted to practical processing issues.

Can you use an extruder to make shrimp feeds?
Current technology and the advantages of this method of production will be reviewed in a talk that will cover all aspects of this process from the raw materials through to drying and cooling before packaging. Final product quality aspects will also be presented.

Starter feed production will be reviewed in another talk and the day will finish with a discussion of upstream processing to improve process efficiencies. It will explore work done on early pre-hydration and the effect on improved production rates, the hydration being either/and combinations of grain tempering and last minute addition of water to ground powders before going into the storage bin that feeds the extruder. This talk will also discuss high speed continuous mixer/choppers to hydrate and add other liquids before the conditioner, and the theory that supports these technologies.

Ways of misting steam and water into existing conditioners and the beneficial effect of these: the presentation will be an overview of techniques that are available to improve product quality through homogenous mixing and heating and to improve production rates and reduce machine wear.

As an end to the day, delegates will be able to sit back and enjoy a presentation on the very latest in contained aquaculture productions systems and the development of entoprotein – an alternative protein source from insects, about to be commercialized.

The (South Antarctic) Krill Industry - How far can krill derivatives become a real feed ingredient substitute? - A Brief Industry Overview

noreply@blogger.com (Linx Conferences) — Thu, 02 Aug 2007 01:11:00 +0000

Dimitri Sclabos, General Manager, Tharos Ltd. E-mail : dimitri@sclabos.com - dimitrisclabos@tharos.biz

Much has been said about South Antarctic Krill (Euphausia superba, Dana) species products, specifically meals and oils, becoming sustainable, competitively priced aquafeed ingredient replacements for brown fishmeal and fish oils.

Undoubtedly krill meals and oils have unsurpassed nutritional qualities that aquafeeds can and should profit from. Nonetheless, feed manufacturers should count on them as one-more feed component alternative rather than being an entire substitute option.

There are three relevant aspects of this fishery that will preclude South Antarctic Krill derivatives from becoming stable, price-competitive feed ingredients; processing and logistic complexities, owner/processors’ options of alternative higher value-added routes and environmental and regulatory aspects.

Processing complexities abound, no matter how simple it may be seen to process “just another pelagic” species, South Antarctic Krill has not proved to be another “typical pelagic species”. Logistic aspects are also difficult to work with, in relation to the area where it is captured and processed as well as the costs involved for this operation.

For key fishing operators (owners), although feed-grade krill meals and oils are relevant end-product targets, there are also other krill derivatives that may add much more value to the at-sea operation, for example pharma-grade krill oils (phospholipids-rich), food-grade whole frozen krill and white tablecloth food-grade meats.

Environmental and regulatory aspects will and need to be seriously addressed in order to prevent the South Antarctic Krill face the same detrimental fishing effort seen on other species if it wants to become a sustainable and environmental-friendly resource option. The major over fishing risk relies on the South Antarctic Krill species’ being key resource for the entire South Antarctic trophic feed-chain.

Palatability Improvement in Shrimp Feed

noreply@blogger.com (Linx Conferences) — Thu, 02 Aug 2007 01:09:00 +0000

Dr Vincent FOURNIER, R&D Manager AQUATIV. Email: vfournier@aquativ-diana.com

To contend with the palatability problems that have arisen as a result of fishmeal replacement in aquafeed, Aquativ has been developing and selling natural attractants for more than four years. Excellent feed intake and growth improvement have already been obtained in laboratory and with aquafeed producers in various species such as european seabass, atlantic salmon, yellowtail.

Some recent trials were conducted in shrimp (penaeus vannamei) in well known testing facilities: the objective was to demonstrate if a good level of palatability could be reached using natural attractants in shrimp diets containing low levels of fish meal.

Growth and preference trials were conducted. Several PE were added to feed formula containing low fish meal levels (LFM), and compared with formula containing a high level of fish meal (HFM) without PE. Shrimps were fed to satiety by feeding trays for 70 and 15 days in growth and preference trials, respectively.

No significant difference was observed between HFM and LFM diet showing that scarce raw materials like fish meal could be successfully replaced with more available plant based raw material when using natural attractants.

The Development Of Novel Feeding Attractants For Sustainable Aquaculture

noreply@blogger.com (Linx Conferences) — Thu, 02 Aug 2007 01:04:00 +0000

Since 2001 the Centre for Environment, Fisheries and Aquaculture Science (CEFAS) has been developing a range of novel feeding attractants to support the development of sustainable aquaculture. The attractants, which are nature identical chemosensory stimulants have been shown in a series of laboratory tank trials to increase feeding activity in a range of fish species.

The feeding attractants, which are in the form of a liquid-formulation are added to the water prior to the addition of the feed. The feeding attractants developed for European cod, (Gadus morhua) tilapia (Oreochromis niloticus) and a penaeid shrimp (Litopenaeus vannamei) have been tested under commercial conditions in hatcheries and production facilities in Norway, China and Thailand.

Initial data from the feeding trials indicate that the application of the feeding attractants resulted in a significant increase in growth of all three species. The results of the studies are also discussed in relation to the application of the feeding attractants for use with reduced fish protein based commercial feeds.
