I decided to write this article following a concrete case, in which I was asked to give an opinion regarding the purchase of fans to cool the cows along the feed line of a certain dairy farm. This manager was 240 meters long and was used to feed (and cool) 320 cows.The dairy owner had two proposals for fans to be installed in the feeding area. The first fan was 50″ in diameter with a 1.5 hp ...

Cooling the cows through a combination of wetting and forced ventilation is the most common method in the world today. I estimate that more than 80% of the cows that are currently cooled in the world are cooled by this method. Today we know very well what is required to cool the cows properly, in terms of the "wetting quality", air speed and the time required for cooling during the day and through ...

Global warming and the constant increase in cow yields aggravate the summer problem on dairy farms and increase the production losses caused to dairy producers. An important part of the losses caused is due to the negative effect of heat load on the fertility of cows that are inseminated in summer. To characterize this effect, we collected data from five large-scale, high-yield dairy farms (1,500 ...

Global warming and the constant increase in cow’s milk yield exacerbate the summer problem in dairy farms and increase the production loss caused to milk producers. In order to quantify these losses, I collected data from five large scale high yielding dairy farms (1,500 to 3,000 cows per herd), located in the Torreon region, north Mexico, characterized by a desert climate, with close to 180 ...
