Webinar #1: Oxidative Stress in Animal Production

Thu, 04 Mar 2021 10:00:39 GMT

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.

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.

Webinar #10 : Resilient Microbiota and Performance

Fri, 12 Jun 2020 00:00:00 GMT

Speakers: Prof Ducatelle, Prof Rychlik and Dr Pierre-Andre Geraert

An animal is in fact an ecosystem with more bacteria cells than host cells. Much of the resilience we are looking for is thus due to its microbiota. A resilient microbiota means a bacterial ecosystem that is able to support external challenges such as dietary and environmental issues, vaccinations, antibiotic replacements,... Birds start their life without being exposed to their mother hens, and rapid growing broilers have to develop their own microbial ecosystem, which need to be stable and resilient in a rather short time.

What links resilient microbiota and performance: more homogeneous performance, reduced mortality, better “resistance” to stress or challenging conditions.

What a resilient microbiota means: How to define it, how long it takes to obtain such a resilient microbiota…

How we influence the microbiota through feed formulation and dietary changes: from feed materials (fibers, substrates) to feed additives (probiotics, prebiotics…) and their interaction with microbiota…

How hot conditions can affect the microbiota …

Are some of the aspects discussed with Prof Ducatelle and Prof Rychlik

But resilient microbiota is only part of the resilience of an animal.

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.
