Don’t sweat it! Effective cooling options for hot summer days

During winter it can be hard to imagine it ever being warm again. But summer will be here before you know it, and an effective cooling system for your cows is a priority. Heat stress in cows can cause issues in health, reproduction and milk quantity and quality. Dairy cows need to maintain a core body temperature between 38.6 and 39.3 degrees. One lactating cow at 1600 pounds produces enough heat to generate the power of sixteen 100 watt light bulbs!

Cows use evaporative cooling to cool themselves down. Because they have a limited ability to sweat, they rely on the heat exchange of their environment. When the air temperature is higher than the core body temperature, the heat is absorbed, but when it’s lower, the cow can offload the heat and begin to cool down. When air temperatures rise above 26 degrees, feed intake can be reduced by 10-20%, the core body temperature rises and blood flow to the gut, uterus and other internal organs is decreased.

The design of your cooling system is very important, as it needs to take into consideration humidity levels, direction of air flow, location of the cooling unit and where your cows spend their time.

What are the options?

High pressure Fog (HPF)

The High Pressure Fog or HPF system creates fine water droplets that easily evaporate, cooling the cows but keeping bedding and surrounding areas dry which reduces infection and disease. It can be highly efficient with water and electricity, and can be installed where cows spend most of their time. A HPF system also utilises humidity, as tests have shown that when humidity is measured at 50%, the overall temperature can drop by 16 degrees. The unit can then have an option of automatically turning on when a certain humidity or temperature is reached.

While this system can be more expensive, a benefit of HPF is that it is a central delivery system which provides greater control. The unit can be installed over the holding pen and used to target the cows instead of their surroundings, reducing waste. 

Soaker

A Soaker system is used by sprinkling the cow’s for 30 seconds to three minutes and then allowing the water to evaporate off their hide with the use of cooling fans. It can be installed over the holding pen, while this is a generally cheaper option, there are some disadvantages. Due to operating at a higher water pressure, the sprinklers will require more regular maintenance. Water may build up, trapping a layer of air between water and skin which can increase the cow’s core body heat. Water runoff will also add to the slurry, and will need to be considered in your effluent management.

Cooling Fans

Whatever option you choose, ventilation is a constant for peak efficiency. There are numerous types of fans that can be used, with placement, angle and size all important factors to consider.

How to choose?

When picking a cooling system you should take into consideration the average temperature and humidity of your farm, its size and your budget. Eagle Direct provides a consultation to determine what suits you and your farm, and we work with you to install and set up your system so you’re ready to go by summer. The main goal of a cooling system is to keep your cows comfortable, and their health and wellbeing is our priority. For more information, we also have a free webinar available with Dr Mike Wolf, who takes a deep dive into the latest research and information regarding cooling systems. Watch Webinar Recording here.

Cow Brushes

Cow brushes are a relatively low cost way to improve animal welfare and promote correct cow traffic in your barn. While cow happiness may never be scientifically proven, US studies have shown that the simple addition of one or more cow brushes to your barn helps to increase cow health, cow comfort, animal welfare and overall performance.

The brush helps by increasing blood circulation while keeping the cows clean, busy and happy in their environment which, by anecdotal assumption, will lead to better milk production. A small investment could pay big dividends for your farm so call us today to arrange a quote.

Hoof Trimming Chutes

Good cow health starts from the ground up. Maintaining hoof health in your herd is one of the most important, but often overlooked, factors in maximising your returns. Wet & sloppy conditions underfoot exacerbate hoof problems and can make your herd more susceptible to injury and microbial entry. From cracked hooves to foot rot, poor hoof health takes a toll on your livestock, no matter what the species.

Good nutrition and ongoing hoof care are the best preventative measures a farmer can take. Eagle Direct works very closely with Comfort Hoofcare – arguably the global leaders in good hoof health. We stock a range of hoof health products in our online shop but it all starts with the animal chute which we can deliver direct to your farm saving you time & money.

Calf Pens

Your calves represent your future herd and future income. When a calf is born it does not have a developed immunity system so keeping these calves safe & healthy in the first 6-8 weeks of life is critical to ensure it can go on to become a healthy productive animal for many years.  Our calf pens or hutches give calves the perfect start to life allowing one to one bottle feeding several times a day, individual health monitoring and a degree of isolation while their bodies develop and outgrow the newborn susceptibilities.

Barn Lighting

Research has shown that a well-lit barn can both boost your bottom line by reducing energy costs and increase milk production. The manipulation of day/night rhythm to achieve a longer-period of light can have significant positive effects not only on productivity but also on health and fertility. Studies out of the US & Europe found that a 16-hour “photo-period” boosted milk production by up to two litres per day more than cows on a natural 8-hour “photo-period”.

Sourcing suitable lights and optimising them for your farm is where Eagle Direct can help. We work with the leading suppliers from around the globe and have access to experts in barn lighting that assist all our customers to find the right solution for their enterprise.

Soaker Lines

In warm weather, cows adjust their behaviour and physiology in an attempt to cope with the heat load. Cows will seek out cooler microclimates or protection against the sun which will often reduces their lying and feeding times and can increase their respiration rates. Production losses and elevated body temperatures can occur and sometimes result in infertility.

Along with fans, soaker lines installed along feed bunks or bedding areas are a very successful way of bringing down cow’s body temperatures and ensuring their comfort. The frequency & location of spraying is an important factor to keep cows at the feed bunk longer and to ensure they are comfortable during rumination periods. Improved cooling translates to better milk production and healthier animals.

Cooling Fans

Ventilation in barns, particularly where cows are tightly packed eg. holding yard/s, should always be considered a priority in any infrastructure planning. Good facility design will create the most effective air movement. Fans will then increase this air movement – moving warm air away from cows and creating air movement over the cow’s skin to enhance evaporative cooling through sweating during warm-hot days across Spring, Summer & Autumn.

Placement, angle and size of fans are all important considerations and will need to be taken into account when designing an improved cow cooling solution for your farm. Used together with soaker lines will have an even greater cooling effect for your animals. Call Eagle Direct today to discuss where your farm is currently at so we can assist you in designing a system that will maximise your investment from both a productivity and cow comfort standpoint.

Silage Equipment

Silage rakes and facers can provide greater consistency in feed quality and ration composition for farmers handling lots of feed daily. Losses through mismanaged silage can easily mount up and with feed being such an expensive commodity, it’s a critical aspect of farming that you simply can’t afford to get wrong.

We all know that the less exposure silage has to air, the better preserved it will be. Silage facers, with their rotating beater, powered by a hydraulic motor, leaves a face that is still tight & even. Using a silage facer or rake avoids unnecessary wear & tear on other farm equipment eg. skid steer & bucket or tele handlers. Facers & rakes also ensure consistency no matter who is doing the job of getting the feed.

Feed Mixers

Mixing feed has advantages for both the farmer and livestock, as uniformly mixed feed components provide better nutrition, improved feed efficiency and cost, and the opportunity to reduce wastage.

In dry times, when much of the feed is purchased off farm with higher costs, wastage and efficiency are even more critical. Improved nutrition benefits milk yield or weight gain, and contributes to animal health and fertility.

Eagle Direct works closely with Canadian based Loewen Manufacturing who are one of, if not the most trusted brand when it comes to manufacturing quality and reliable feed mixers. The Loewen Vertical & Horizontal Feed Mixers come in a range of sizes (12m3 to 60m3) with tandem or single axle undercarriage. If you’re considering investing into feed mixing equipment, make sure you talk to us so we can show you a Loewen mixer in action on farm.

Feed Automation

Presenting feed to your livestock in such a way as to increase dry matter consumption and the production of milk while minimising associated costs is nirvana to the farmer.  At Eagle Direct we’ve done a lot of work with ValMetal and specifically their Pro-Feed 2020 which is a self propelled feed pusher which uses an auger to push the silage or hay back to the animals increasing odour and palatability.

A robust, waterproof controller with a 10’’ (254mm) touch screen is very easy to use and can save a heap on labour costs. The menu is simple and user-friendly – the feeder can also be controlled from your computer, tablet and cell phone; no matter where you are.

Sand & Manure Separation System by McLanahan

McLanahan Sand & Manure separation systems are used to settle out and wash bedding sand, and can be set up in multiple ways depending on the type of manure conveyance system on the dairy. In some cases, the sand-laden manure from the alleys is loaded directly into the separator, where bedding sand is settled out and washed. On a dairy where flush water is used to move the manure and sand bedding, the separator is used to wash the sand after it has been settled out either in a McLanahan Channel System or scooped from a sand lane. In all cases, the Sand-Manure Separator produces a clean, reusable sand bedding product with minimal organic content, suitable for reuse as recycled sand bedding.
