Mr. Entz, what I wanted to say is that hotter the water less positive effect will come with the addition salt to it.

Dear Dr. Moran, how nice to read your comments, bringing important consideration to the complex "multifaceted process" of heat stress. Take care

One thing is hot weather and the other is hot water. You are right on saying that birds adapts themselves to hot weather, But, there is no adaptation to hot water.

Mr. Entz, we need to consider hot weather and/or hot water. If we have hot weather and cold water, we need to preserve the water temperature based on putting the pipe line deep in the floor to maintain it cool from the origin. In this case, flushing the water helps. However, if the water comes hot from the origin, flushing does not work. Still, new negative pressure chicken houses projects are not ...

Mr. Entz! Research done by Beker and Teeter (1994) showed that the addition of 0.5% KCl in the water improved broiler performance when the water temperature was 10,0oC ou 26,7oC. When the water temperature was 43,3oC, the KCl addition did not have effect. That is based that tongue neuron sensors react to water temperatures above 25oC.

I hope the best for this new PSA leaders.

Regarding the use of sodium bicarbonate, it works, but the temperature of the water must be around 25 to 28ºC. Higher temperatures are detected by lingual thermosensors that restrict the water consumption, and the bicarbonate effect can be reduced.

Dear All! I like Dr. Ruiz's arguments very much. Restricting feeding, besides light control, is a very complicated issue once we depend on people to make the restriction, and it is impossible to see all farmers doing whatever should be done, based on the company´s recommendation. At the hottest period of the day, leave the chicken alone. This is a recommendation to broilers that are produced ...

I fully agree with Bob Brill´s comment.
