I congratulate the authors for the information contained in this article, which I fully agree with. I also understand that the article that was published on ENGORMIX, under the title Digestible lysine levels obtained by two methods of formulation of diets for 22-to-42-day-old broilers, under my guidance, is somehow consistent with the information described here.

As we have already made our study considerations similar to this one regarding the determination of the LD requirement exactly for lactating primiparas, we continue with a similar opinion on the matter as follows;From my own experience, in an experiment we conducted with primiparae during lactation, in which the feed intake was fixed, based on 95% of the voluntary consumption of a batch of primipa ...

I congratulate the study team on the researched subject. However, I would like to express my opinion about the meta-analysis study with lactating sows. In addition to a series of details that compromise the analysis and conclusion of the study, such as body condition of the sow at farrowing, variation in the standardized number of piglets per litter, in the feed consumption of sows and duration of ...

I congratulate the team of researchers involved in the idealization and implementation of this study, with emphasis on the methodology, especially in the number of birds per experimental unit and in the number of replicates. It is also worth highlighting the fact that the authors used suboptimal levels of lysine in the experimental diets, which makes total sense. Despite the positive aspects highl ...

Mohammad Hosein Shahir I don't think I made myself understood. My consideration was made based on your explanations made to the questioning of Dr Oscar Briceño, where it is stated that levels of the amino acids valine and isoleucine in the requirement of birds, is sufficient to neutralize the antagonism of excess leucine with these two amino acids., This statement does not seems correct to me, I t ...

The team of researchers involved in this study would like to report that the fundamentals presented to Dr Oscar Briceño, where they consider that the use of adequate levels of valine and isoleucine in the feed would be sufficient to neutralize the antagonism of excess leucine with these two amino acids, it doesn't seem right to me. I think this statement would make some sense if the improvements o ...

I congratulate the authors of the work by the subject surveyed. However, I would like to make some considerations; - As well as the behavior of the insulated pigs is altered compared to group maids, the fact of using an animal per experimental unit could not interfere with the immune response, altering the standard of cytokines secretion .; -The.; - Finally I think that the increase in treonin dem ...

M. T. Kidd, I congratulate the team of researchers for the information contained in the article on the reduction of crude protein (CP) in poultry feed. Although the matter was well founded, I would like to make a consideration. In addition to what was discussed, which highlighted the complexity involved in reducing CP in poultry diets, including the need to include some amino acids considered non- ...
