Very interesting the reports presented, however, that aminoacids defined as non-essential, as is the case of glutamine and glycine mentioned at the topic presented, other than glutamate and aspartate, which also are conditionally essential, how it is used of the concept of the ideal protein in the preparation of the rations in the farm, if these practices will reduce the protein level, adjusting the relations of essential amino acids with lysine, with the levels of these important amino acids (glutamine, glycine, glutamate, aspartate) being reduced sensitively, in field conditions where the immune challenge is greater. Important to notice that in the studies using glutamine and glycine used in the report, use was supplemented in diets that served the established requirements of animal waste. To make it clear that we are not positioned against the reduction of crude oil, we are simply leaving some considerations that, in my opinion, need to be carefully considered.
Another important aspect to be considered is the dynamic character of ideal protein, with the relationships of essential as with lysine varying in the function of the condition of animal stress, environmental or immune.
Finally, as an exception, we would like to emphasize that for potatoes after the reduction of path of ratio is clear is a vibrant practice, in reason of the possible negative effects of PB fermentation in the GI.
