When we talk about thermal stress in pre-weaned calves, often we discuss cold stress. However, calves can become environmentally stressed when temperatures are too cold or too hot. During extreme cold or hot temperatures, calves utilize extra energy to maintain their core body temperature. The temperature range at which a calf uses no additional energy […]
Managing heat stress in dry cows is just as important as it is for lactating cows because it determines the amount of productivity and success a cow will have during her lactation. It can also influence the future success of the daughters and granddaughters of the dry cow.
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.
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.
A sloped screen separator filters solid waste from liquid manure by letting liquid pass through a screen while solids slide off. It works best when manure has 2–4% dry matter and can remove nearly half of total solids, reducing odors and storage buildup.
Preventing new mastitis cases and treating existing cases is essential to excellent milk quality.
Paul M. Fricke, Professor of Dairy Sciences, gives a talk about Pregnancy Diagnosis in Dairy Cows using PAG Levels in Blood and Milk.
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.
UW-Extension Milk Quality Veterinarian Pam Ruegg shares in this UW-Extension Dairy Science Webinar series research findings associated with the recently published Impact of Bedding Choice on Udder Health Freestall Herds.
In this presentation, Dr. Kent Weigel discusses genomic selection for feed efficiency in dairy cows.
