Excitement is building for youth livestock exhibitors across the county as they prepare for fair season and while the heat is on for competition, so is the temperature. And no matter the hours of work and preparation you’ve put into your livestock projects, heat stress is a challenge to plan for and manage.
While we typically think about heat stress in extreme temperatures, the reality is that anytime the temperature exceeds 70 degrees, livestock are adversely affected. Heat stress causes increased respiration rate, suppressed appetite, fatigue, and dehydration — all signs of a lowered immune response. When we think about these traits and the way they affect production, it becomes very evident that the strenuous expectations we put on our show livestock to perform at the highest level and look exceptional while doing so clearly becomes a challenge.
As managers, it is imperative to follow best practices and implement some simple, but important steps to ensure fewer setbacks due to heat stress and in turn, experience greater success with our show livestock projects.
Here are some heat stress tips from BioZyme:
- Take a proactive approach, and don’t just react to the temperature changes. Watch the weather, and make wise decisions. It is a lot harder to bring down livestock’s body temperature once they are hot than it is to manage it before it rises.
- Manage your facility, and make sure it is comfortable for your animals. Be sure your animals can get out of direct sunlight into a shaded setting. Managing air flow and temperature is very important. Whether your facility at home has fans, misters, or even an elaborate cooler, controlling airflow is crucial. If you can provide an environment that minimizes exposure to the direct sunlight and allows for air to move through, even in the most extreme heat, you can drastically reduce the outside temperature. Keeping bedding wet down and misting water in the air will also help cool the air that fans push through your facility.
- As the temperature rises, consider modifying your feeding program to accommodate cooler periods. Just like humans, livestock don’t want to eat when it is extremely hot. Feed earlier in the mornings so they have a chance to eat and be moved into the barn before it gets hot. Also pay attention to the location of their water supply. Smaller troughs provide more water flow and result in cooler water. Make sure lines that serve as water sources are not exposed to heat resulting in the water in the lines to get extremely hot.
- Rinsing animals with cool water multiple times a day will help drop their core temperature better than anything else you do. When rinsing, focus on cooling their underline and head as it will help cool them faster. Don’t just get them wet, but allow cool water to run over them a while to help drop their body temperature.
- It doesn’t take long for livestock to feel the impact of heat stress when they are removed from the comforts of a temperature-controlled environment. It is essential to think about this prior to leaving for a show. For cattle that have been kept in a cooler it is very important to raise the temperature of the cooler a week to 10 days ahead, every day slowly increasing the thermostat to help them acclimate. Taking them straight from a cooler to a hot show will cause extreme stress which will ruin your opportunity for success. A new product called Climate Control Paste from Sure Champ has been shown to drastically help in the acclimation process when used a week to 10 days before a show. It helps all show livestock species handle heat stress by lowering the animal’s body temperature by increasing blood flow in a safe, fast, and natural way. Keeping livestock on the paste through the show has proven to keep them more relaxed, cool, and comfortable, resulting in better appetite and higher energy levels allowing them to look their best on show day.
- Strategically plan when you haul to shows. During hot periods of the year hauling at night is the most ideal to help reduce the time they will be exposed to the heat of a trailer. Make sure you have adjusted ventilation on trailer to allow for adequate air flow while traveling.
- Most importantly once you arrive to the show it’s critical to maintain the same schedule of caring for your stock. Continue to feed early and maintain body temperature by keeping animals rinsed regularly and under fans. It’s easy to get excited to see your friends and lose focus on your projects, but lots of preparation and time have been put into your animals so it’s critical to continue your same routine at the show that you have done at home. Heat stress can be a challenge at shows but can also be turned into an advantage for those who prepare properly.
