Efficient milk production under heat stress condition

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. If intake is 20% down, then increase energy and protein source by 20%.
2. To maintain ionic balance in body, electrolites should be added in water.
3. To avoid losses due to humidity- increase cross ventilation by fans and reduce the density of animals in a shed.
4. Timing of feeding should be during cool hours.
5. Plenty of availability of water throughout the day to avoid uroconcentration.

These measures will reduce the impact of heat stress though not eliminating it totally.

I think that Dr. Mukesh Sharma is missing the point from the principal message of my article
Cows 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 genetics, but this is always more expensive and less effective than just cooling the cows, also in very extensive and small dairy farms in countries like India and Pakistan.

Please suggest the cheap ways to keep cows cool. I had also read that the addition of temperature in faranheit plus humidity should be less than 100. So how can we maintain it during warm as well as humid months?.

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 cooling farms.

Respective please explain me how to change the dry ration of cow from summer to winter? When ever I came to know cow increasing on particular feed. When winter start cow start down their milk . Please explain about feed.

Presently in northen hemisphere winter is going intense explain me feed used for cow to increase milk and combact with chilling climate. I am no veterinary prefessional but medical prefessional.

I have a few questions:
Example of fat supplements
What should be the normal temperature of room in summer in summer?
What should be normal temperature in winter?

Addition of normal temperature in farenheit value in the dairy alongwith humidity should be less than 100 for better cattle health.
