[Music] yeah we have a lot of questions about ingredients and diets and for instance uh there is here edema asking questions any advice what to do when shifting from amy to any where can i get reliable any values of ingredients uh any advice i think the point is that for that you need to to to get a net energy value of ingredients that's the unique to that as far as i know uh most recent uh i say recent i mean uh published over the last 15 or 20 years feeding tables provide net energy value of ingredients for pigs not for poultry yet so in the case of pigs inroad tables are producing net energy brazilian tables are you providing net energy nrc uh 2012 is providing net energy fed now tables with cdb tables so most uh i would say big tables are used for for fix are providing net energy value of ingredients so uh that's uh the point uh in the case of pigs i think i have one interesting comment to give i think you can slide number 29 sometime a few years ago we produced a software where a software that is able to recalculate and to correct i would say the energy value of any ingredients that is available in the world for recalculating its net energy value so so that's one example so clearly uh the information about net energy of ingredients is available in feeding tables one thing but the feeding tables provide i would say fixed net energy values for one ingredient and everybody knows that the each ingredient has variable characteristics over time and so on and so on or between silos between ships and so uh it's important afterwards try to to have some correction or some adaptation of the energy values according to the actual composition of the ingredient and so that's that's where in the case of pigs the evap software is able to recalculate uh in the case of poultry there is nothing really equivalent yet apart from i would say uh also one slide slime number 30 which is a production of the french feed feeding tables of database are on the feet and this uh this software which is just on coming i mean it's not fully fully uh finalized but it's uh close to the end i think provides a net energy of any values in the case of poetry according to the chemical condition of the ingredient so clearly there are a lot of values so the question was more general i think if you want to move from amy to net energy the first thing is that you need net energy values of ingredients but afterwards how to do that i think that's rather easy you can recalculate or estimate your net energy values of all your ingredients in the matrix according to the equations or according to the feeding tables and the scranton and one thing is that at the beginning you you shouldn't formulate according to net energy immediately i think it's better to keep on formulating on the software you are using or the principle or the system you are using uh tme and yen and so on and so on and afterwards you get negative value according to what you are using but progressively you change where you look at the net energy values you are obtaining and progressively you change to net energy value system so we could spend hours on that uh in order how to move from me to net energy from d to net ng but i would say that's very easy and you should be confident on the net energy value equations which are available uh both for for pigs and also for poultry or for broilers recently and even laying ends so the information is getting more important and more available and that should be easy to move to net energy in all cases so on medicare also someone on the aspect of the table we need a new version of the tables with the network you
