I congratulate the team of researchers for the work. However, considering the scientific experience of the researchers involved in the study, I would like to make the following consideration. By the characteristics of the fiber, mainly of the soybean meal, would not be the mannanase e or the galactosidase, the enzymes more efficient than the xylanase?

Alvaro, I agree at first with the meaning of your considerations. However, it should be considered that at levels of 0.90 and 1.00% lysine the ratio of glycine + serine and that of essential and non-essential amino acids does not characterize these possible deficiencies. On the other hand, in the higher levels of lysine these factors should rather be discussed. Thank you for your contribution, in ...

Introduction Over the years, animal nutritionists have developed alterations in the quality of diets intended for broilers aiming to increasingly adapt these diets to meet the nutritional requirements of these birds. Studies on the protein nutrition of broilers have considered the use of digestible amino acids in the formulation of diets, which makes it possible to reduce the amount of dietary pr ...

Mustafa Ayazi, while understanding his point of view, continues with the view that the difference in bird performance between phases would be related to the fact that the temperature of 32 C represents a lower stress intensity for birds from 0 to 21 days, compared to 22 to 42 days of age. However, I think it is important to emphasize that in biology there is no absolute truth.

Dr Peter, I congratulate you on the article. Very interesting reports on the actions of carnitine. I would like to question the effective antioxidant action of carnitine in the metabolism of broilers submitted to heat stress. As I am aware, high temperatures increase the oxidative stress of chickens by decreasing the activity of the UCP decoupling protein. In this case, due to the increase in prot ...

Dr. Alain, as far as my question is concerned, I would like to clarify that I was not referring to diets with the addition of acid, but with vegetable oil.

Dr. Alain, the strain of Bacillus used produces the enzyme BSH, like some strains of Lactobacillus? In case it does, its use in diets containing oil, could not compromise the performance of chickens?

Dr. Zhang, I congratulate you on the published article. If I am not mistaken, I think that one of the problems of using the medicated diet with high doses of antimicrobials in the production of pork that is adopted in some countries is exactly the effect of these drugs in reducing the production of antimicrobial peptides that are naturally produced by animals due to the decreased activity of the m ...
