To the question of the friend from Indonesia:The combination of wetting with forced ventilation works the same goodin dry as in warm and humid climates. I have farmes usin this system in South China, Vietnam, El Salvador and other tropical regions of the worls with very good results in overcoming heat stress negative impact on pure Holstein cows.

Thanks Aziz for the warm words.To all members, you can see in another article of mine published in Engromix (Summer to Winter ratio Index) that there are dairy farms in Israel who reach same milk production per cow in summer as in winter (above 40 kg/cow/day) without any manipulation in feeding, just intensive cooling!!!These farms also double summer conception rate, as compared with non cool ...

Maintain drinking water at 20 degree Celsius. Animal water intake will go up. Provide extra energy, protein and minerals. Keep an watch on iodine as it being essential for adequate functioning of Hypothalamus which controls the thermo-regulatory system.

I think that Dr. Mukesh Sharma is missing the point from the principal message of my articleCows can be cooled easily, in a cheap manner and all kind of climate and management to reduce great part of the negative impact of hear stress on the cows. I think that this issue must be the basic one to be discussed. Obvious, if you don't or can't cool the cows, then you must manipulate feeding and maybe ...

We must understand how heat stress is impacting the productivity and reproductivity. It is observed that cow's feed intake goes low yet water intake remains stable or increased slightly. But nutritive requirements for maintenance and production remains the same. Under the circumstances, I would recommend as follows: 1. Condense the energy and proteins in feed as quantity of intake goes down. ...
