Heat stress (HS) has detrimental effects during all stages of dairy cattle life. Cows that experience HS reduce dry matter intake, milk yield, and its composition. In addition, HS has major effects on a cow's health and fertility and negatively impacts a cow's welfare. The decrease in the efficiency of milk production in such conditions increases the negative contribution of the world dair ...

The negative effects of heat stress and ways to deal with them are currently among the most important research areas. The reason for this is clear, heat stress has become the greatest cause of economic losses to dairy herds, including in regions with a relatively temperate climate, which have only begun to feel the problem in recent years.Evidence of the importance of the issue can be found in the ...

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 ...

Lecture given as part of bpt (German National Veterinarians Association) meeting 2024, held as part Euro Tier exhibition, Hannover, Germany. The principal factors affecting world dairy sectors in summer are climate change (global warming) and the Increase cow’s productivity. The high yielding cow generates more than 2000 W of heat (like 25 persons), which is much above her ...

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 ...

Monitoring and transmitting in real time and continuous manner the body temperature of the cows has become a reality these days. This can improve the effectiveness of cooling treatments given to the cows, with all the benefits that can arise from that. The following article presents the knowledge and experiences accumulated in the last years in Israel, based on monitoring cow's body temperatur ...

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 ...

@Rajeshwaran , thanks for the comment. It is Holstein breed (by the way, the reason it was not mentioned is that i thought it is clear to readers that no other breeds reach such high productivity
