#15/20 - Current broiler genetics respond very well to AAs more than energy...

Wed, 14 Oct 2020 00:00:00 GMT

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

Answer:
I accept that animals respond maybe more to amino acids because the birds are selected and raised for depositing proteins and so amino acids supply is a very important pusher in the system.

Q&A #15/20 - Webinar #11 on Net Energy, Feed Formulation and animal performance
After education on Net Energy in the SEV, time now to get our expert, Jean Noblet answering questions from the field. The short introduction will be followed by 9 questions answered by Jean, Pierre Cozannet with Pierre-André Geraert as moderator of the webinar.

#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.

#6/8 - NE of diets & ingredients

Thu, 28 May 2020 00:00:00 GMT

And now, how to evaluate Net Energy of Ingredients and Diets?

It’s a Research activity, but scientists have developed NE equations based on digestible nutrients, or on Digestible or Metabolisable Energy with corrections factors that are reliable and can practically be used.

The key message: 1 NE equation = 1 NE system

#5/8- How to measure Net Energy?

Thu, 07 May 2020 00:00:00 GMT

Now you know how to measure Net Energy, 1st by determining Energy Gain and 2nd by evaluating Fasting Heat Production. Let’s summarize the process and point out the key steps.

#7/8 - Impact on Formulation

Thu, 07 May 2020 00:00:00 GMT

Speakers: 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. Ranking ingredients differs between DE, ME or NE systems changing the feed formulation and thus the incorporation of ingredients, particularly protein and fat sources. Net Energy is useful for poultry and pigs and show similar benefits.

#4/8 - How to measure Net Energy?

Thu, 07 May 2020 00:00:00 GMT

The 2nd step to determine Net Energy, measuring Fasting Heat Production and expressing it on a refined metabolic weight basis, key to evaluate the maintenance.

Short Educational Video (SEV)-Net Energy #4/8

#3/8 - How to measure Net Energy?

Tue, 05 May 2020 00:00:00 GMT

And now, how to determine Net Energy?
1st step: measuring Energy Gain or Retained Energy by Comparative Slaughter Technique or more “friendly” by indirect calorimetry, through O2 consumption and CO2 production, calculating Heat Production.

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.

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.

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.
