Ruminants are built to eat quickly, so paying attention to what is going into their mouth will ensure they receive proper nutrition. Starch utilization is improved by making sure corn is broken down into smaller pieces, not just cracking the kernel into two pieces. The increased exposed surface area of the inner parts of the corn kernel allows the animal to get the most out of their corn silage feed since rumen bacteria have better access to the starch inside the corn kernels. The improved access to the starch is one reason it is so important to have proper corn processing.
Studies to evaluate cocktail forage mixes were conducted in 2021 and supported by the UW Dairy Innovation Hub. Research discussed here includes collection of on-farm data from four farms growing a cocktail forage mix and a lactating cow feeding trial at the UW Marshfield Agricultural Research Station (ARS). Please refer to the “Cocktail Forage Mix […]
The nutrient needs of dairy heifers change with age and size as they approach maturity with feed intake increasing and diet nutrient concentrations decreasing (Table 1). This is due to changes in growth with heifers having a higher rate of protein growth prior to breeding with slower protein growth as they approach mature body weight. […]
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.
To minimize heat stress, there are three key things farmers can do to help cows on pasture stay healthy, productive, and comfortable during hot spells.
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.
