Summer feed storage and feed bunk management

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.

Using DairyCOMP 305 to Assess the Potential Impact of Heat Stress on a Dairy

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.

Effects of Heat Stress on Dairy Reproduction

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.

Impact of Heat Stress in Mammary Gland Development and Health in Dairy Cows

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.

Managing the heat in pre-weaned calves

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 […]

Dry Cow Heat Stress Management

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.

Dealing with Hot Weather in Grazing Systems

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 Ration Management During Summer

Dairy cattle are susceptible to heat stress during much of the summer. Dietary adjustments can help maintain nutrient intake and production.

Using DHI Herd Summary Report to Assess Potential Impact of Heat Stress on a Dairy

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.

Feeding the newborn calf

Feeding high-quality colostrum to the calf as soon as possible after birth is the most important thing you can do for calf health. It is especially important for dairy and beef x dairy calves destined to leave the farm at a young age to receive colostrum.
