[Music] so I'm sure that you that stimulate the questions on the on the platform maybe we we can now stop on the presentation and the time is really flagging so sorry for the participants so we will start to ask few questions just now and for the question we will not ask in fact feel free in fact to send your question on the web platform and we will answer to the question with our experts later on so one of the first question is what difference between synthetic amino acids and amino acid present in the ingredients and that's it I would say typically for the formulator but I would prefer maybe to ask yep and and my to answer to that question well that's in peak nutrition that's a question that was asked many many years ago when batter hampered did the study where he showed that well free amino acids in attica amino acids are readily absorbable and so they are immediately available to the animal where is perhaps the proteins was added the energy sources or the other protein sources are not available many studies have been done ever since and we have never really seen an effect for instance of feeding frequency on amino acid use so in terms of metabolic what the animal sees once it is absorbed is amino acids peptides but that's it so a potential difference would be in the gut and does the gut halves have receptors for amino acids software proteins and perhaps there is a response in that but in practical feeding I have not seen any difference in in terms of amino acid use free amino acid use compared to even when you compare I would see us wine with a meal feeding and I would say broilers with more nibbler and eating the whole day and so on yeah and I won't go into detail with the word my battery am because he explained that very very well but we have a meal fed bird and we've wondered the same thing in our conceptual idea of amino acid absorption but what I would like to point to is that the difference is we're looking at an individual amino acid versus a pool of amino acids so we feed for example the high amino acid density diets for birds and for an economic optimum in a certain scenario we were moving the whole plane of nutrition forward and when we do that with feed right amino acids we're doing that with certain amino acids and we're creating limitations and others so that's another concept and think we need to be very very keen to remember so sure we can I would say debate a little bit more on that so maybe we can take another question even if the time is flagging I think we have some time to answer to some questions so yeah an interesting question regarding the object is we always talk about breast meat and do we consider that immunity needs for the development of breast is the same for scientists explain typically of all the parts and the trials we do and this some of this was presented earlier this year at the Australian poultry science symposium in Sydney and with the low protein diets if we miss it and typically not typically but many of the times we do miss it in formulation to get the response to where it needs to be we have a reduction in breast meat yield some by default based on a yield bass parts percentage with lower protein diets or with amino acid balance it's not geared toward optimizing white meat yield because that's what the bird wants to do you can maintain a feed conversion see conversion and increase dark meat yields at the same time that's pretty clear but you know you would recommend slightly different I would say amino acid profile absolutely in Asia Pacific when's our concern sure most of rest of the whole cast and CEO you need to feed for feed conversion there because pushing the bird more for white meat yield they probably don't want to push the bird more but they're probably pushing via conversion but you don't need to push the bird in those environments to get the carcass percentage of dark meat yield because that's going to be where the lower percentage of breast comes into play so that can be really interesting to reconsider that may be your last question is based on the he'll interview as formidable et could we think about short-term amino acid supplementation for specific teas you talk about God tells you talk about different aspects beyond I would say meat quality as we consider for instance an extra simplement ation of immunity to - solver sanitize you to solve some get functioning and so on not that I know of the the first point that comes to my mind when you mention me quality is looking at the withdrawal time in commercial boilers potentially putting something in the water we've got to remember the rapid turnover of amino acids you know a pool of amino acids 48 72 hours but we have experimented for example with tryptophan back in the 90s with dr. Moran looking at feeding or providing tryptophan in the water before slaughter so to relax the birds in the particular environment so I think we could also consider looking at amino acid supply prior to these situations for for me quality as well and I don't want to get into something like you know myopathies because I I think that identified long before the end of the trial but for sure we could we that would just be one example and and next year because you will be talking at advance your next year so on hotend conditions or environment in question would be quite another challenge on the amino acid requirements I think time is really flagging so I'm sorry for for the people who ask questions so don't forget that you can still drop your questions on the web platform and we once were to the question with our specialist as a joke I would say I would like to ask a question to our two invitees we for years and years we think about the EDL protein based on the lycée you know for beta because it started on swine and so on and it's a essential amino acid for swine button in broilers or poultry I would say the most essential one is missing it why not you have ideal protein based on lies in for swine and no sign in for broilers or any princess to come out of that but said to the public again ya know well I I mean for lycée Francis we don't think just in terms of lysimeter in terms of lysine it relative to net energy or metabolizable energy yeah and we have to have a reference because lysine to net the energy ratios change over the lifespan of an animal and people have some idea about how it changes threonine to net energy will change the same way tryptophan to net energy will also change so so rather so so what other than having an image how does amino acids relative to energy change it's it's good to have a reference and a lysine is a relatively stable reference and then think of well how does training to lyceum what should the ratio be even though people sometimes think that three ninja lysine may change and because of the contribution of maintenance may change so is it important to change the reference and should we have a reference I think yes because it makes life for the nutritionist much simpler the question is really in fact to see if there is no bias when we consider when a poultry for instance compared to would it make a difference if you would use my athenian as a reference I'm not sure Mike well yeah yeah we have a feather situation not sure we're gonna have know how to get around clearly but with poultry the same concept it is true with the swine and that is that the lysine is highly limiting and if the whole body protein accretion is is at a high rate versus maintenance is almost zero so we have that same situation even though lysines not first limiting in poultry but we need a reference and these amino acids are interplaying threonine and methionine are interplaying when we look at the intestinal interaction types type environments so we need a reference is it the best one yeah and as we as we said we need over France we need a common base yeah so it's maybe ah yeah it's a best situation but clearly the way we have more to learn so yeah that question may be answered soon who knows yeah okay thank you very much so I would like to warmly sunk out to the speaker so that 11 million from rain and the professor my kid from Arkansas and also lane from Cargill in Rotterdam and I would say you will have the answer on all your questions on the web platform you will be able to listen to the program gain on the podcast and so on you can it will be divided in section because already this time it's a bit longer compared to the previous one but you will have the possibility to look as a whole live webinar as well as different parts of the way of the webinar we hope you enjoy the webinar which you will continue to be addicted to the fictional dot online platform we give you appointment for the next fictional live webinar in February mid February and it will be devoted to equality and the next one in April will go back to swine average give more information later on so I would say bye bye everyone and looking forward to seeing you next February and because it's a final closing of the last webinar of 2017 I think I would like to own the alt the whole team on free channel to wish you Merry Christmas and Happy New Year [Music]
