Ventilation is an important part of managing a dairy barn for maintaining air quality, removing heat and moisture, and providing a comfortable environment for dairy cattle. There are typically three types of ventilation systems used in dairy buildings: natural, mechanical, or a combination of the two.
Manure can be used in a sustainable manner by returning nutrients to the soil to grow crops that feed animals. However, on many livestock farms, manure poses operational, economic, and environmental constraints. Managing manure every day requires labor and money. Losses of manure constituents from the system result in negative environmental impacts such as degrading water and air quality.
Phosphorus is an important mineral added to animals’ diets and is critical to their development and growth. However, much of the phosphorus is excreted and ends up in manure. For many crops, if manure is applied at the rate needed for nitrogen, too much phosphorus is applied, which may lead to a buildup of excess phosphorus in soils. Phosphorus buildup can lead to increased phosphorus loss and the resulting environmental consequences. If manure is applied to meet crop phosphorus needs, supplemental nitrogen application is required.
Livestock produce high protein sources of food, but they also produce manure. When used effectively, manure can provide a sustainable source of fertilizers, energy, and other valuable products. However, when not managed effectively, manure components including nutrients, organic matter, and pathogens can be lost to the environment causing negative environmental impacts.
In 2019 Cargill conducted a Feed4Thought survey of consumers from the United States, China, Mexico, and Spain. In this survey, they asked consumers to identify the word that best described what they wanted a farmer to be. The survey showed 30% of respondents wanted farmers to be “sustainable.” The second most-used word to describe what […]
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 […]

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 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.
Farmers enrolled in DHI receive several reports regarding herd performance. The Herd Summary Report (HSR) encompasses three main sections: Milk Production, Reproduction & Genetics, and Inventory. The milk production section has eight blocks—the focus related to heat stress will be on Blocks D, F, and G. The Reproduction & Genetics section has five blocks—the focus for heat stress will be on Block L.
