Very important contribution, Dr. Saume. Never before gut health was so much considered as it is today.

Dear Kees! I fell sorry. The academia keeps fighting on methodology and the industry keeps waiting for something that is feasible to be used.

Yes, Dear Sifri. Fantastic time in our professional lives.

Dear Gene, the equations from the works of Dr. Sakomura and her coworkers are fantastic. We have been using them, very much. However, the discussion always come from the energy values that we stablish to different ingredient sources, mainly corn. When we follow theoretical weekly energy consumption and relate it to the weight of the hens we can see if we are under or overestimating their energy va ...

Dear Gene! This is an important gap on our formulation side. One calorie in broiler diets can cost from 0,08 to 0,18 US$ (more or less, depending the year and the country). But, I know that this issue it is not fixed due to the complexity of the "simple" starch composition and the post harvesting consequences that can happen when it is bad treated. I would be happy enough if we can have at least a ...

Dear Gene! Still, this is something that bothers me. Starch is a such complex molecule, with so many variants, even made just by glucose, that is not easy to fully consider its energy value. We need to find better ways to express the energy that comes from it.

Great discussion. However, I always wonder how long will take to move from total starch to an analysis of amylose and amylopectin of a specific starch? So, starch is an important indication of the caloric potential of an ingredient. However, we still have many question to be addressed (amylose:amylopectin; how retrograde types of starch can affect the final energy?; how much we can affect the ener ...

Dear Aaron, be in touch with it is a pleasure for me, as well. Sorry not knowing the 5 to 6 years work of DSM. Congratulation! For sure, in the future, all the data collected will make assumption more precise. I strongly believe on that!

Dear Aaron! This variability is big in humans, as well. However, based on million of analysis, the doctors can suspect or confirm health condition based on minimum and/or maximum figures. If someone starts collecting published data on chicken blood parameters, we will be able, eventually, to predict future diseases, as it is predicted in human health. Our comments can motivate some of our universi ...
