A lot of information has been published in the last decades, dealing with the negative effect of summer heat stress on the productive and reproductive traits of the high yielding cow. Very limited information existed however, up until the last years, on the effect of heat stress on the feed efficiency of cows (as estimated by the feed to milk ratio). Knowing the full extent of the e ...

Heat stress related production loss, compromised welfare and cattle mortality are global concerns, which are increasing in the context of climate change and increase productivity of the cows. Cattle response to heat stress varies, based on individuality and thermal environment. In this article I intend to describe heat stress monitoring, in individual and herd basis, making use of thermal indices, ...
