Heat stress effect on milk production and cow's metabolism

Heat stress has a negative effect, not only on milk production, but also on the cow's metabolism. Periods of high heat stress will become part of the memory of her metabolism and produce negative effects long after the high heat has passed. This is why it is important to equip farms with efficient systems that allow the cow to evacuate a maximum amount of calories from her body during the hottest periods and almost when they are laying in the cubicle which is the most part of the day. The cooling mattress allows the cow to evacuate a maximum of calories to maintain a body temperature that will allow her to perform at a high level. Scientifically calculated benefits of cooling solutions: OHIO STATE UNIVERSITY - Agricultural Technical Institute + 2 kg (+ 4,4 lbs) / day over 14 weeks for cows benefitting from a cooling solution (240 dairy cows studied) CORNELL UNIVERSITY ( NEW YORK ) Production/cow/day for cows lying on uncooled bedding: 31.2 kg / day (68.6 lbs.). Production/cow/day for cows lying on a cooling solution : 34.9 kg / day or + 3,7 kg / day ( + 8.1 lbs. / day). UNIVERSITY OF FLORIDA - Department of Animal Science A study shows the proven impact of cooling pregnant cows: - on milk production after calving - on the preservation of the genetic capital of the fetus that will be a future producer.
