Dr. De Gussem is quite right in referring in his interview to the fact of the large feed intake that occurs with modern broilers and the implications it may have in reference to dysbacteriosis or what he also called bacterial enteritis. A review of the definition and description of dysbacteriosis by Teirlynch et al. (2011. Morphometric evaluation of "dysbacteriosis" in broilers. Avian Pathology ...

Dimcho Djouvinov, your comment is quite interesting, and since you are writing from AB Vista I assume you have quantitative data to support your assertions, would you share your data? Thanks

Dr. Albin and Dr. Wiseman, yes indeed I also agree with your comments because the video presented is actually a clip of a longer video and it is not fully representative of all of what I have to say reference full-fat soybeans. But both of you, Gentlemen, are authorities on the subject, have lots of experience and knowledge on the nutritional value of full-fat soybeans, so you can also further dis ...

Although I am a regular attendant of the International Poultry Scientific Forum (IPSF) in Atlanta, for some unknown reason I missed this presentation at the 2019 IPSF. It would be interesting to see the whole set of data since you (Chen et al, at Novus International) assert that trypsin inhibitors and urease activity are poorly correlated in solvent-extracted soybean meal samples. We don´t k ...

Mr. Aslam, the discussion on urease activity and its correlation with trypsin inhibitors applies only to SOYBEAN MEAL. Because full-fat soybeans (FFSB) are generated through different methods such as roasted soybean seeds, it is not possible to establish a general correlation across the different methods. In the case of SOYBEAN MEAL which is generated worldwide mostly by the solvent extraction met ...

I just would like to suggest that the authors carefully review the units for the treatments (T2, T3 and T4) as presented in the abstract. Something is not right.
