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.

Speakers: Prof Peter Surai, Dr Mario Estevez and Dr. Pierre-André Geraert

The basis of oxidative stress (Prof Peter Surai) and its impact on meat quality (Dr Mario Estevez) & share questions and answers during the roundtable.

Questions and Anwers

Q: A comment on flavonoïds, even if they are absorbed at low level some of them play an indirect role in inducing at gene level endogenous antioxidant systems.

Reinforcing the anti-oxidant defenses of the gut definitely improve its resistance to aggressive factors such as dietary ones (induced by mycotoxins for instance) or induced by microorganisms (bacteria, virus). Polyphenols and flavonoids may bring antioxidant benefits reinforcing the host response to xenobiotics.

Q: Is there a significant difference on the meat between chicken fed with Organic selenium and another fed with mineral selenium?

We assume that you mean organoleptic properties: improving the antioxidant status of the meat often is "indirectly" perceived by consumers influencing their choice. The conservation of the meat is also improved reducing the changes in color, texture,.. during storage or processing. Drip losses are clearly reduced when birds receive an organic selenium source compared to a mineral one.

Q: Oxidative impaires male fertility .. What about female ?

Indeed, the spermatozoids are clearly affected by oxidation. But ovocytes and particularly their membrane is also rich in polyunsaturated fats and prone to oxidation. Most parameters linked to egg production such as the export of vitellogenin by the hepatocyte toward the ovary is conditioned by membrane phospholipids. Preserving them from oxidation will help to enhance fertility. Hatchability is also clearly affected by oxidative stress situations and can be restored by using the right antioxidant solution.

Q: You said free radicals are used as weapons against bacteria, play a role of messenger: what about (too) high antioxidant intake?

Indeed, you're right. Free radicals are normal elements in the metabolism that help our body to get rid of xenobiotics. Antioxidant have to be balanced and an excess of one will not compensate for a deficiency of another and might event counteract the benefits of their nature. Proposing a balanced of efficient antioxidant solutions is thus key to improve animal performance under challenging conditions.

Q: Is oxidative stress affecting fertility ?

yes indeed, hot conditions and ageing are good examples of oxidative stress that affect fertility. An optimal balance of antioxidants has long been shown to improve fertility in a wide range of animal species including human.

Q: Is oxidized fat in the diet a source of oxidative stress?

Yes, oxidized fat can induce some toxicity depending the level and thus increase oxidative stress to the animal. It has long been worked at, but nowadays it is sometimes difficult to link the actual used index (iodine, …) to the decreased performance. However, lipid peroxydes have clearly a negative effect on sensitive molecules to oxidation. Antioxidant systems can help to alleviate those negative effects, particularly the selenoprotein Glutathione peroxidase 2 have been demonstrated to detoxify different lipid peroxides.

Webinar #2: Understanding Gut Health in poultry production

Thu, 04 Mar 2021 10:00:39 GMT

Speakers: Prof Theo Niewold; Prof Filip Van Immerseel and Dr. Pierre-André Geraert

Watch more on gut health, from gut microbiota (Prof Filip van Immerseel) to gut inflammation (Prof Theo Niewold) & share questions and answers during the roundtable.

Q&A Session held during the live:

Q: Are the biomarkers available commercially?

Lots of biomarkers can be easily measured in analytical labs, however reference values are still missing to help define what is a dysbiosis situation vs a normal one. Scientists are working hard to get such figures and we can expect to have practical and efficient tools in the coming years.

Q: Hello Pierre-Andre, Greetings from Venezuela. What are the residual effects of misuse and abuse of AGP and antibiotics in general, in pigs and poultry?

The world misuse or overuse of antibiotics in both humans and animals has conducted to these antimicrobial resistances that we observed worldwide. In countries with a significant duration of ban on AGP's and more prudent use of antibiotics a clear reduction of antimicrobial resistance has been reported (EFSA reports, 2015-2016).

Q: One of the alternatives you mentioned was herbs, do you think that they can help us to control Clostridium?

It is important to consider that no one alternative can be considered as the only solution to get rid of Clostridium perfringens. However some solutions such as some Bacillus subtilis can exhibit a specific efficiency on such a pathogen bug. Essential oils and herbs could have some effect on the host to reinforce its resistance as well as on the pathogen by itself. But guaranteeing consistency and delivering to the right level of the intestine are still important issues for those alternatives.

Q: Besides improving animal growth and wellbeing, does improving animal gut health help to fight against viral infections?

Reinforcing the gut health or better speaking the gut wall will improve resistance of the animals to challenges through bacteria, parasites and virus. We have also observed that a mycotoxin challenged gut wall would better resist if there was supplementation with a specific Bacillus subtilis through better gut wall integrity and gut immune system.

Q: Can externally supplemented butyrate has the same potency as internally synthesised by bacteria?

Very interesting question not yet solved by the experts. When giving formulated butyrate to be delivered at the intestinal level the positive effect on the enterocytes and gut mucosa can be observed. However, when influencing the microbiota profile stimulating the butyrate bacteria producers directly or indirectly through the cross feeding would give a localized and dedicated effect with more long term consequences through the rebalancing of the microbiota.

Q: I thought organic acids are best alternative for AGP, also most economical one. Is it correct?

Organic acids can contribute to control microbiotia through both pH reduction and their radicals penetrating into the bacterias. However, they are not specific to any bacteria and might also affect commensal bacteria that could impair performance as observed at high doses or very young animals. Moreover, coating is also important to consider.

Q: What is the difference between probiotics and prebiotics? Which kind of alternative will be more developped in the next years according to you?

Probiotics are live micro-organisms which, when administered in adequate amounts, confer a health benefit to the host. Conversely, prebiotics are nutritive substrates that are only metabolized by the gut microflora to benefit to the animal performances and health. Scientists are working more to develop nutritional solutions based on combination, such as symbiotics which combine pre and probiotics, to guarantee the efficacy of those alternatives.

Questions & Answers Session with Prof. Hervé Blottière

Thu, 25 Apr 2019 00:00:00 GMT

Speaker: Prof Hervé BLOTTIERE, MICALIS & INRA, Paris, France

Produced by the endogenous bacteria or supplemented through the diet, butyrate exhibits lots of positive effects on intestinal integrity, gut immune function, regulation of gut-brain axis up to acting on pathogens such as Salmonella.

During this Advancia Academy 2019, Worldwide experts answered questions on butyrate from endogenous microbiota or dietary supplementation to strengthen health of the animals.

Advancia Academy 2019- Butyrate: from the Nutrient to the Messenger - Questions & Answers Session

Dietary butyrate – fundamental for the intestine: what does it do in poultry?

Wed, 24 Apr 2019 00:00:00 GMT

Speaker: Dr Joshua GONG, Guelph R&D Centre, Agriculture and Agri-Food Canada

Depending on its galenic form, butyrate increases growth performance and breast muscle deposition in young animals. It also reduces the lipid deposition in broiler strains as measured as abdominal fat and intramuscular breast fat and shown by reduction in several enzymes involved in lipogenesis or lipolysis.
Butyrate modifies the gut functioning and the gut microbiome favorizing the beneficial bacteria.

Advancia Academy 2019- Butyrate: from the Nutrient to the Messenger - Presentation

Metabolic insight into the action of butyrate in the gut and beyond

Wed, 24 Apr 2019 00:00:00 GMT

Speaker: Prof Kolapo AJUWON, Purdue Univ, USA

Butyrate improves the gut integrity through strengthening the tight junctions as well as stimulating immune response and reducing inflammation induced by pathogen bacteria. Moreover, it is clearly shown that endogenous, from fiber-degrading intestinal bacteria or exogenous butyrate results in increased circulating level in plasma and brain.
Butyrate has indeed a strong influence on the gut-brain axis: stimulating PYY, serotonin production. Butyrate also appears to stimulate lipid metabolism at the cellular level through increasing insulin sensitivity, adipocyte differentiation and glucose uptake.

Advancia Academy 2019- Butyrate: from the Nutrient to the Messenger - Presentation

The use of exogenous butyrate, and the stimulation of endogenous intestinal...

Wed, 24 Apr 2019 00:00:00 GMT

Speaker: Prof Filip VAN IMMERSEEL, Faculty Vet Medicine, Ghent Univ, Belgium

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.

The intestinal frontier integrity: the tight junctions

Tue, 25 Sep 2018 00:00:00 GMT

Speaker: Dr Raquel MARTIN-VENEGAS, Fac Pharmacy, FFUB, Barcelona, Spain

The selectivity of the intestinal frontier is ensured by the good functioning of the tight functions. Their complex protein structure helps to ensure the intestinal frontier integrity and most of the absorption through the enterocytes and the transcellular pathway. Dietary solutions, such as OH-Met, pro- and pre-biotics can strengthen the tight junctions and thus the intestinal frontier.
