Cécile Berri; Prof Massimiliano Petracci and Pierre-Andre Geraert have a Questions and answers session with the webinar attendees.

Webinar #4: Meat Quality issues beyond myopathies

Most poultry conferences focused on breast myopathies (WB, WS…), but do not forget drip losses, cooking and processing losses as well as meat color change during storage.

Meat quality experts from academia as well as industry help us to understand those issues and to address the potential solutions.

#20/20 - How do you expect the NE to change (in time) considering the changes...

Wed, 14 Oct 2020 00:00:00 GMT

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

Answer:
I’m not very concerned about the impact of changing the genetic on the DE or ME or NE change, but I think we have shown in many studies in pigs that the k value wasn’t changed much according to the genotype of the pigs.

Wed, 14 Oct 2020 00:00:00 GMT

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

Answer:
The point is that you need to get the net energy value of ingredients. As far as I know, most recent feeding tables provide net energy value of ingredients for pigs, not for poultry yet.

Wed, 14 Oct 2020 00:00:00 GMT

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

Wed, 14 Oct 2020 00:00:00 GMT

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

Answer:
Net energy is calculated from DE or ME. The effects of fiber level or fiber composition or in that case, soluble dietary fiber will affect first the DE or the ME content in poultry or in pigs and afterwards the net energy will be affected according to some variation of the DE or the ME value. .

Wed, 14 Oct 2020 00:00:00 GMT

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

Answer:
There was a lot of work on Net energy a long time ago in the 60’s. Unfortunately, these studies were not followed by applications in the field. That’s only quite recently that there were new studies conducted on poultry for Net energy equations and progresses.

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

Answer:The Net energy can be calculated from any good indicator of the DE or the ME or the digestible nutrients content. Why not using or predicting the DE or The ME value of an ingredient according to infrared methods and use that predictions for calculating the net energy.

Wed, 14 Oct 2020 00:00:00 GMT

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

Answer:
What should be done when you do a least cost formulation is that you start from the energy values of your ingredients and you assume that the values are additive and the software will tell you what should be the combination of the ingredient in order to achieve a targeted energy value of the diet..

Wed, 14 Oct 2020 00:00:00 GMT

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

Answer:
What in practice you need for talking about requirements is to know what’s the energy concentration of the feeds you are formulating. Most of the time, the simple answer about requirements, it’s what should be the energy concentration of my feed.

Wed, 14 Oct 2020 00:00:00 GMT

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

Answer:
The energy digestibility in pigs is quite different in growing pigs and in other pigs. In the way that when you have very fibrous diets and very fibrous ingredients you have a big difference between other pigs and growing pigs.

Wed, 14 Oct 2020 00:00:00 GMT

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

Answer:
What you need first is to establish your net energy value of ingredients, so you have to choose one net energy system, one net energy equation that is available and that has been validated. You can’t use net energy system without getting net energy value.

Wed, 14 Oct 2020 00:00:00 GMT

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

Answer:
Both, at the ME value and also the NE value, what we obtained was by putting enzymes in the feed we improved a little bit the ME value as may have been demonstrated in many trials over the last ten or 15 years.

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.
