A greenhouse gas is any gas in the atmosphere capable of absorbing heat from the sun and stopping it from radiating back into space. Many greenhouse gases occur naturally in our environment at low concentrations. However, human activity is increasing the concentration of greenhouse gases in our atmosphere, thereby trapping, and storing, additional heat and […]
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.
Even in Wisconsin, summer days can be hot enough to cause heat stress for cows. The thermo-neutral range for cattle, in which they do not need to expend energy to keep their body temperature stable, is about 41°F to 77°F. When the temperature is above 77°F, especially with high humidity, cattle can have reduced production, […]
Dairy cattle are susceptible to heat stress during much of the summer. Dietary adjustments can help maintain nutrient intake and production.
With changes taking place in feed testing in commercial labs, Randy Shaver & Luiz Ferraretto help make sense of what’s showing up on the reports that nutritionists and farmers are looking at.
In this presentation, Dr. Kent Weigel discusses genomic selection for feed efficiency in dairy cows.
If we understand and use the biology and physics of forage drying properly, not only does the hay dry faster and have less chance of being rained on, but the total digestible nutrients (TDN) of the harvested forage are higher.
