I am enjoying very much all this discussion. Thanks, Dr. Guevara for bringing your paper to this forum. Just to reinforce, least cost feed formulation starts with different paradigms that are difficult to make broad comparisons. The ingredient data base, with nutrient composition is, most of the time, not adjusted in a real time situation. Also, not all companies have strong laboratory support to ...

Dear Dr. Ruiz! I am very glad on reading your text. It is very clear and you were able to demonstrate your points based on literature review and long experience working in this field. This paper must be saved in all archives that discuss soybean meal quality, to be used, when needed. Thanks for all knowledge shared.

I fully agree with Dr. Waldroup's consideration. Let's avoid confusion where it is not there.

I totally agree, Mike! Sometimes I see people treating the water with no water analysis.

I totaly agree! Water with more than 1000 ppm of TDS can require an amount of acid not practical to adjust the pH. But, as it was said, each case requires analisys of samples of water from the same source in different conditions of the year.

Dear All!I reinforce the comment of Dr. Charles Ibe, together with all alternatives used to reduce heat stress effect, we should not forget the water temperature, that usually becomes high at high environmental temperature. When we talk about water temperature, at hot environment cooler the better. How many farms are cooling sistematicaly the water for the broilers?

Dear All!Nice comments on water acidification. However, none of the participants suggested the final water pH, after acid treatment, that will be effective. Can we discuss a little about the value that we should expect?

Dear All! I understand Dr. Czarick consideration, that is based on experimental results. However, when I am visiting chicken houses, I can see the reaction of chicken when the CO2 is below 1500 pmm and above it. This is the reason that I try to look on that value as reference. If it is not possible to have CO2 below 1500 ppm all the time, I do not know. What I know that is possible to reduce CO2 ...

Dear All! I am surprised with some figures suggested, regarding CO2 level at the chicken house. The figures can be that high, in some cases, due to the equipment, that can be not that precise. Otherwise, my CO2 measurements, that I make continuously, show that above 1500 ppm it is too much and the birds start sleeping, gatting lazy. When the minimun ventilation, transiction ventiliation of tunel ...

Excellent article and consideration. Yes, this period is the most important period of the life of the chicken. My only consideration is related to the time to start eating (It is important that chicks find feed and water in the first 48 hours). We recommend that the chicken need to start eating and drinking (or vice versa?) as fast as it is possible, after placement. After 24 hours we recommend ch ...
