Roundtable on Feedase concept, WPC 2022

Mon, 08 Aug 2022 17:40:02 GMT

Speakers: Rick KLEYN, Marcio CECCANTINI and Pierre-André GERAERT

Enzymes are specific to substrates, present in the different raw materials of the feed. All components of the feed are interacting and when developing the value of an enzyme it's important to consider the total level of antinututritional substrates within the feed as well as their interaction. The supplementary enzymes are complementary and work as a whole on the feed, that is the Feedase concept.

Considering such an approach will help to optimize the benefits of enzymes in feed formulation.

Fibres - a tool for better sow management

In swine industry, the focus is on growing-finishing pigs for the meat production but two phases are very important to consider: the sow from pregnancy to lactation and the piglets which will have to face a drastic change of feed presentation from milk to solid feed and like kids the mixing with others and the separation from the mother.

To manage sows in addition of the nutrients she need to grow its piglets it's important to consider the fiber content. Knud-Erik Bach-Knudsen is sharing his thougts and expertise on the topic.

His key messages is followed by the slides of his presentation.

Webinar#3: Feedase The Global Feed Digestibility Approach

Thu, 04 Mar 2021 10:00:39 GMT

Speakers: Prof K.E. Bach Knudsen, Prof M. Kidd, Dr J. Noblet and Pierre-André Geraert

More about the feedase effect. Prof K.E. Bach Knudsen, Prof M. Kidd and Dr J. Noblet have discussed about the indigestible fraction of feed and its impact on the global feed digestibility.

Questions and answers session held during the live

Q: What elements or factors in feed and feed manufacturing destroy enzyme structural integrity?

Mainly feed processing with water vapor, pressure and temperature are stressful to protein structures and depending on their level and duration could significantly impair enzyme structures and thus efficacy.

Q: As substrate concentration increases is enzyme dose or rate of activity more important?

The efficacy of the enzymes is related to breaking down few bonds to decrease the mocelular size and restore the nutrient accessibility or decrease viscosity. Most of enzymes are not used to completely degrade a substrate like endogenous amylase releasing glucose, but are more used to decrease the length of the polysaccharides to reduce impact on viscosity or accessibility for the endog enous enzymes. However, high doses of enzymes such as phytase need enough substrates to work on. Moreover NSP-enzyme dose response is usually curvilinear reaching a plateau irrespective of the substrate concentration.

Q: What are the anti nutrients specifically in corn?

More than anti-nutrients we should talk about low digestible or poorly digestible components that may affect the overall feed digestibility. As example the insoluble arabinoxylans highly ramified that you find in corn can reduce its nutritional value.

Q: About corn and soya bean diets. what is the percent % of cell wall fibers? and what are the exogenous enzymes required?

We have published many synthesis on those levels and recommend the following to get the best overview (Geraert et al., 2005, Dietary carbohydrates: a review of their physicochemical properties and digestibility in poultry and swine, 18 pp, Proc Eastern Nutrition Conference, ANAC, 10-11 May) as well as the most recent paper by Bach-Knudsen (Fiber and nonstarch polysaccharide content and variation in common crops used in broiler diets, Poult Sci, 2014, 93:2380-2393). Enzymes required to hydrolyse NSP from corn are endoxylanase, arabinofuranosidases, acetylxylan esterase, feruloyl esterase and glucuronidases. For soybean meal, a large range of enzymes is required including pectinases, xylanases, debranching enzymes.

Q: What is the different in anti nutrients between wheat and corn?

Most of the NSP structures exist in both cereals. However, the proportion of soluble NSP is higher in wheat than in corn and the arabinoxylans are more branched or ramified with arabinose residues in corn than wheat.

Q: You still haven´t mentioned the role of Proteases to increase total and aminoacids digestibility. Can you also explain the differences between birds and pigs regarding the mode of action of enzymes ?

Fundamentally exogenous enzymes are similar for both species but they may not release their effect at the same level of the digestive tract (pH, transit time…). Proteolytic enzymes are very abundant in the metabolism of our animal species, however, there is often a limited access to the protein in the vegetables for those endogenous enzymes. That's why NSP-enzymes having a range of enzyme activities have shown improvement in amino acid digestibility. Such an effect is not direct on the proteins but indirect giving more access of the chymotrypsine, pepsine... to the substrates.

Q: How this enzyme could behave in the rumen? Do you think it could improve feed digestibility in Dairy and beef cattle?

NSP-enzymes have already been evaluated in ruminants. They indeed improve the access to the fibres and may result in increased energy availability but have not yet often justified enough return-on-Investment.

Q: Beyond phytate and the specific compounds from soy, what anti-nutritional factors can you considered important in corn-wheat-soy diets?

Soybeans are riched in pectins, complex polysaccharide structures, and corn contain highly ramified arabinoxylans. Those structures limit the accessibility to the nutrients and are thus important to consider to improve feed digestibility?

Q: Organic acid can improve ndf digestion?

Improving the functioning of the intestine through lowering pH for instance will have an effect on feed digestibility. However, the animals do not possess the enzymatic activities required to truly digest fibres and improving the gut functioning will not generate new enzyme production such as xylanase or b-glucanase. Lowering pH especially in the hindgut might favour fibrolytic bacteria and subsequently improve NDF digestion. Unfortunately, the yield of such action might be very low.

Scientific Background on Feedase : The Global Feed Digestibility Approach

Thu, 04 Mar 2021 09:59:50 GMT

Prof K.E. Bach Knudsen; Prof M. Kidd and Dr J. Noblet shared their expert insights. Enzymes have long been used in animal feeding to get rid of these anti-nutritional components. However, they have only recently been considered on their global effect on feed. It will allow to get their full economic value and improve animal protein production sustainability.

Wed, 07 Oct 2020 00:00:00 GMT

Speakers: Dr Jean Noblet, Dr Pierre-André Geraert and Pierre Cozannet

Last June, we completed the release of a series of 8 Short Educational Videos on Net Energy (NE) presented by Dr Jean NOBLET (ex-INRAe) who largely developed the NE concept in swine and participated to the development of NE for poultry during his scientific career.

Net Energy: everything you wanted to know about NE but were afraid to ask! This SEV series was designed to better understand the concept of NE, the methods to determine NE, how to calculate NE of ingredients and diets, the impact of NE on feed formulation, and the benefits in terms of performance and usage of additives.

During this webinar, Dr Jean Noblet, Dr Pierre-André Geraert and Pierre Cozannet discussed on : Net Energy, Feed Formulation and animal performance: How to move from theory to practice.

#8/8 - NE & performance

Tue, 16 Jun 2020 00:00:00 GMT

Speaker: Dr Jean Noblet

Based on his long scientific experience, we have asked Dr Jean Noblet to give us the key points to know about Net Energy and why NE is the most efficient system to address nutritional value of feedstuffs as well as expressing the animal requirements.

Net Energy is clearly the best system to predict performance and production costs. It allows to better value low protein diets, dietary fat addition and enzyme supplementation. NE is a more robust criteria when important diet or environmental changes occur.

Franck Ducatel, Operation Director at Cargill Premix France and president of Tecaliman, Joan Brussosa, International Sales/Project Manager at Mangra and Marc Perel (Solution Application Manager) were on the set to host the live webinar. Anna Perez, Reaseach Director Analysis, IRTA was also interviewed to give an analytical point of view.

Questions and Answers session

As mentioned during the live webinar, the “liquid additive equipment maintenance check list” can be downloaded via: http://bit.ly/39SbeQn and to know more click here.

Can you comment on the sequence of addition of the different liquids in the main mixer?

First, a dry mixing time is needed to homogeneize the solid ingredients. Before addition of micro-liquids, it can be quite short (a few seconds). Then comes the addition of liquids -time depend on quantity and flow). They can be applied simultaneously since the flows do not overlap. Lastly, the third mixing time allows to finalize the repartition of liquids within the batch. All automation systems have different approaches to consider these different times but things must be cleared between the feed manufacturer and the PLC company.

Compared to powder dosing, the injection of liquid requires specific equipment whose maintenance is more delicate. What are the practices to recommend for monitoring "weighings"? (pump, plastic or metallic material, injector ...)

Maintenance of liquid system is not a big deal. It consists mainly on checks and verifications. Please have a look to Adisseo's check-list proposal.

Is the premixing of liquids a recommended practice?

As far as possible, managing each liquid seperately is recommended (from storage to spraying). But if there is no adverse interaction, liquids can be put together before addition in the mixer.

How to ensure the good dispersion of the active liquid materials in the mixer?

Spraying is a matter of choice of nozzles (number, type, size, angle), location, pressure and viscosity in some cases.

From the point of view of the incorporation of liquids, are there differences in behavior between the different types of mixers?

The equipment supplier must consider the type of mixer (single/double shaft - ribbon/paddle...) to implement the nozzles. Spraying quality is of bigger importance than the mixer type. The filling ratio of the mixer is also of importance (distance between the sprays and the feed; are the shaft and ribbon or paddles covered by the feed?).

If we have powder micro ingredient and want to apply it with oil on feed, what would be the suggested mode of application, as oil suspension (powder directly in oil), as water dispersion (powder into small quantity of water and than water solution into oil) or as an emulsion?

It mainly depend on the physical and chemical properties of the additive (particle size, solubility, rate of inclusion, stability....). Today this topic is more research program.

Is there any limit as for the amount of additives that recommend applying with a post-pellet dosing equipment? (enzymes and/or probiotics)?

Fortunately, additives are quite concentrated. Even if the manufacturer wants to spray 2 or 3 different products, an addition of 1 liter per ton or a bit more is doable.

What is your opinion about the feed mills having PPLA system without sieving the pellets before liquid application. Can this system be accurate enough?

Of course, this is not the best option. THe final result will then depend on the 3 factors: initial quantity of fines in the feed, pellet durability, stresses during feed storage, transportation and distribution to the animals.

Which is ithe most efficient Post pellet liquid applicator available now? For Fish feeds, With less cost, Any options...Pls explain the working if possible.

Many suppliers propose proper PPLA systems. For fish feed, adding liquids continuously in a drum coater is common. A more recent technique is vacuum batch coating to apply high levels of fats and oils. Liquid additives are applied at the same stage.

Thank you for the ongoing live about liquid additives in the feed mill. We often face the following question from our customers on liquid application system.Kindly requesting your insight on the same. Can we mix macro ingredients (oil) with Micro ingredients(Amino acids/Acitifier) while spraying into batch mixer? Or All Micro ingredients together ? Thank you for your clarification.

As far as possible, managing each liquid seperately is recommend (from storage to spraying). But if there is no adverse interaction, liquids can be put together before addition in the mixer.

How should the liquids and palatabilizer be added together or separately?

In general, palatants require less accuracy in term of dosage and spraying compared to other types of additives. They can be easily sprayed on a mechanical conveyor. This is why they are independent most of the time. Before mixing with another liquid, incompatibility of molecules must be assessed.

Is dry mixing necessary in the mixing time or we can skip it and start liquid spray after loading?

With flowmeters we can have dedicated lines and mixing them into the manifold is optional. We can use different manifolds for those liquids which could not be mixed. It is a closed and cleaner system.

How can we choose between hidraulic or atomizing nozzles.

Refering to Post-Pelleting Liquid Application, the optimum is to create micro-droplets, not a mist. Pure hydraulic nozzles will not produce micro drops, so air is necessary but no so much because we want to get a fine dosing (micro drops) but avoid nebulization (mist).

How do I define the maximum inclusion based on free water resulted from this liquid additive?

In formulation, water content of liquid additives must be considered the same way as for solid ingredients (a value in matrix). In practice, water content of additives is never limitating. With weighing scales it is necessary to add each liquid separately and sometimes mix them before addition into the mixer or use dedicated scales for each liquid. The scaled vessel always keeps traces of the previous mixture and is more difficult to flush and clean.

What are the benefits of flowmeters comparing to weighing scales?

With weighing scales it is necessary to add each liquid separately and sometimes mix them before addition into the mixer or use dedicated scales for each liquid. The scaled vessel always keeps traces of the previous mixture and is more difficult to flush and clean.

What are the advantages of mass flowmeter compared to volumetric flowmeter?

A mass flowmeter measures Mass Flow (kg/min), regardless the actual density value. If there are changes in density value, the flow meter corrects it automatically.
A volumetric flowmeter measure Volume Flow (l/min). As the dosing is made in mass, it is necessary to change from Liter to Kg in the electronics using the actual density value. If the density varies, the conversion to Mass could be slightly affected and alter dosing accuracy.

What is the best sequence for adding different liquids? Is it ok to spray all liquids in the mixer at the same time, if the mixing time is very short?

Please refer to the 1st question in the Forum.

After a mixer profile test, What should we recommend a customer when the CV of the liq is not as good as the powder? What are the advices to improve CV for liquid?

This is a very open question. Apparent heterogeneity can have different sources: actual quality of spraying (place, geometry, pressure, steadiness of the flow...). Let's not forget the analytical process i.e. sampling and lab analysis.

Dietary modulation of gut microbial short-chain fatty acid metabolism

Speaker: Dr Petra LOUIS, the Rowett Institute, Aberdeen, UK

Microbiota has multiple functions and effects on the host: barrier against pathogens, immune interactions, release and transform dietary phytochemicals, xenobiotics and host metabolites, produce short chain fatty acids that influence host health.
Non digestible carbohydrates or fibres are important substrates for this gut microbiota as well as resistant starch greatly influence the microbiota composition and metabolism. More than the individual bacteria types, the metabolic bacterial network is important through the cross-feeding between fibre-degrading, oligosaccharide users, lactate or acetate producers which will give substrate for butyrate producers. Some carbohydrates are more butyrogenic or propionigenic. Similar interactions exist in amino acids and proteins within the microbial community. Future will be based on modelling microbiota metabolism showing that interactions between microbes, environment (pH, …) and dietary substrates (indigestible fractions) are essential.

Salmonella is colonizing the ceca. Thus, butyrate needs to be protected to have an effect against Salmonella through a clear anti-virulence effect by downregulating virulence genes. A large part of antimicrobial use is for intestinal disorders and coated butyrate supplementation shows a reduction in Necrotic enteritis (Clostridium perfringens) occurrence.
Butyrate is a key molecule for strengthening gut integrity, reducing gut inflammation and improving tight junctions. Lots of gut bacteria are butyrate producers helping promoting a better gut health and as feed supplement could further reduce necrotic enteritis and other gut dysbiosis. Cecal butyrate producing bacteria can be stimulated with dietary xylan-oligosaccharides which further increases cross-feeding lactate to butyrate using bacteria.

Mucosa-associated bacterial communities are important for gut health. Butyrate-producing bacteria seem essential. Feeding strategies (eg prebiotics such as AXOS, probiotics) can steer towards butyrogenic (mucosa-associated) taxa in the gut. Biomarkers of the host response are important tools for the development of future efficient gut health solution. Butyrate, even from dietary origin, seems to have potency to reduce effect of pathogens in the intestine.
