Fall calf work and weaning season is here! This year we are carrying a new to us (although not new to the market) product to help keep your cattle calm during stressful events.

SecureCattle® is a high quality, easy to use pour-on solution, that allows cattle to better control their reactions to stress.
It is an analog of the bovine appeasing pheromone (BAP) which is naturally secreted by the sebaceous gland located on the skin of the mammary gland. It is a safe, sustainable, and effective solution that improves the productivity and well-being of cattle by eliminating the negative impacts of stress.

Other key points
✴️ 5ml dose for all animal sizes

✴️ single application site, no need to apply in two separate spots

📢Attention equine owners📢

As of August 1st, 2026 we will no longer be running IN HOUSE coggins testing.

What does this mean for you? We can still do the bloodwork and health papers to get you on the road, we just send it to an outside lab. This outside lab runs the tests daily Monday-Friday, and we usually have results back by end of next business day.

That being said- you will have to plan ahead a little bit if you know you are heading out of state or to an event that requires a negative EIA (Coggins) test.

If you have any questions, please let us know!

The temps are going to rise this week! Cattle can be at risk for heat stress, just like our pets. This article outlines some tips for reducing heat stress in your cattle to keep them healthy through this next heat spell.

Hot week ahead 🔥

Between increasing humidity, 90+ degree days and 75+ degree nights, the summer climate in Iowa put cattle at risk of heat stress. Cattle that have not shed their winter coat, are heavier, dark-hided, and/or have poor immune systems are especially vulnerable. Here’s a few things producers should keep in mind:

Water💧
Dehydration is the biggest threat. In general, summer water requirements are about 2️⃣❎ winter needs, and heat events elevate requirements more. Plus, during heat stress events, cattle will consume water quickly. Ensure tanks have an adequate flow and consider adding extra tanks to reduce crowding. A flow of at least 1.5 gallons of water per hour per animal is recommended to meet drinking demand.

Handling ⚠️
Avoid processing or transporting cattle during heat events. If it cannot be rescheduled, plan handling for early morning. A steer’s core temperature peaks approximately two hours after the peak environmental temperature, taking longer to dissipate heat, meaning evening handling does not provide the same advantage as morning handling. Provide ample space and offer airflow, shade, and water in holding areas. Work efficiently with low stress handling practices and in small groups to reduce the time cattle are in holding areas to less than 30 minutes.

Mitigation strategies 🪰
Planning ahead and providing areas to reprieve livestock from heat is key. Decrease stocking rates if possible to increase room for cattle to move and dissipate heat more effectively. When utilizing shade, provide at least 25 square feet per head, whether temporary or permanent. Utilize fans and vents in barns to facilitate airflow. Sprinkler systems can help, but need to wet cattle thoroughly with large water droplets and allow complete drying between cycles. Don’t forget - the water supply must support both drinking and cooling demands. Controlling fly populations is also beneficial, as biting flies will make cattle bunch up, reducing cooling.

Check cattle early and often. Expect feed intake to be impacted first by animals experiencing heat stress. Watch for excessive panting, drooling, lethargy, or any other signs that an animal is struggling more than others, and work on cooling them down. Early action is the best strategy to prevent serious issues.

Given the forecast next week, plan ahead to keep your cattle (and yourself!) healthy and hydrated!

We wish you all a fun and safe holiday weekend🇺🇸
