English | Spanish El tiempo caliente puede traer una larga lista de problemas para las productoras lecheras. Cuando las vacas están sobrecalentadas, se comen menos, producen menos leche, tienen función inmune reducida y recuento de células somáticas levantado y muestran fertilidad reducida. Un aumento en vacas cojeras frecuentemente sigue la temporada de calor. En olas […]
English | Spanish A medida que aumentan las temperaturas de verano, las vacas lecheras corren un mayor riesgo de sufrir el sobrecalentar. Las vacas sobrecalentadas sufren de una ingesta reducida de pienso seco, lo que lleva a una producción de leche reducida. Los agricultores también pueden ver una reducción de la fertilidad o la pérdida […]
Each summer, dairy farm producers and their employees work through days of extreme heat and humidity – often starting in May or June and continuing into September. While we certainly need to protect our dairy cattle during these hot days, it is also an important time to be conscious of how to protect ourselves and our dairy farm workers during summer heat.

How Can You Find the Tell-Tale Signs of Heat Stress in Your Records? Here are a few of the key areas to watch for: Reduced milk production. Butterfat depression. Declines in reproductive performance. Increases in clinical and sub-clinical mastitis. Increased morbidity in transition cows. Following are examples of the resulting data you can use to […]
Hot summer weather can be hard on feed ingredients and total mixed rations (TMRs). It is vital that feed quality and aerobic stability be maintained during this challenging season. Doing so will minimize nutrient losses while optimizing cow intakes which are often compromised due to heat stress challenges.
Dairy producers often struggle to quantify the impact of heat stress on their operations. The ability to use dairy management records to identify seasonal trends is critical to assess potential heat stress related losses. Diving into a dairy’s herd management software can help a producer quantify where the losses are occurring and, with some easy calculations, determine the profitability of investing in cow cooling measures.
Heat stress not only affects the productive ability of your cattle but also their ability to conceive and sustain a pregnancy. It is important to understand the effect heat stress can have on reproduction and how you can help minimize the effect.
Heat stress occurs when an environment impacts the ability of a cow to get rid of body heat. Cows need to be raised in an environment where temperatures are within their thermoneutral zones to achieve their maximal genetic potential. Failures to establish adequate environmental temperatures can dramatically alter behavior, health, and productivity of cows.
Hot weather can bring a long list of problems for dairy producers. When cows are heat stressed, they eat less, produce less milk, have reduced immune function and higher SCC, and show reduced fertility. A spike in lameness often follows the hot season. In severe heat waves, cows can even die. In addition to the economic burden, the discomfort from heat stress also reduces animal welfare.
