Protecting Your Livestock from the Heat

Anyone who has spent a summer in Arkansas knows the combination of high temperatures, humidity and long dry spells can be tough—not only on people, but on livestock as well.
And to make matters worse, many parts of the state are still experiencing drought conditions. The July 2 U.S. Drought Monitor showed drought conditions persist across most of Arkansas with the central and southeast portions of the state being classified as being under “severe” to “exceptional” drought conditions.
Regardless of the type of livestock you keep on your homesteader – chickens, goats, sheep, pigs or cattle – they all feel the effects of extreme heat, and taking a few simple precautions can help keep your animals healthy, productive and comfortable throughout the summer.
Here are some practical ways you can prepare for hot, dry weather.
ensuring your chickens, pigs, goats, sheep and cattle continue to thrive until cooler weather returns.

Water Comes First

Nothing is more important during an Arkansas summer than a dependable supply of clean, cool water.
As temperatures climb into the upper 90s and beyond, livestock can easily drink two or three times as much water as they do during cooler months. For example, a mature beef cow may consume 20 to 30 gallons—or even more—on an extremely hot day.
Check waterers several times daily, especially during heat waves. Keep troughs and poultry waterers in shaded areas whenever possible, scrub away algae regularly, and make sure automatic waterers and float valves are working properly. Many homesteaders also place multiple water stations throughout a pasture or chicken run to reduce crowding.

Shade Is Worth Its Weight in Gold

Providing shade is one of the easiest ways to reduce heat stress.
Natural shade from hardwood trees is ideal, but portable shelters, loafing sheds, shade cloth or even well-secured tarps can make a tremendous difference in open pastures.
Chickens, pigs, goats, sheep and cattle all benefit from having a place to escape the afternoon sun. Animals that have access to shade are generally less stressed and more likely to continue eating and drinking normally.

Helping Backyard Chickens Beat the Heat

Make sure coops have plenty of ventilation by opening windows, vents and doors whenever it is safe to do so. Small fans can improve airflow in enclosed coops that have access to electricity.
Many people who keep poultry also offer frozen treats such as watermelon, cucumbers, peas or corn during the hottest part of the day. Fresh fruits and vegetables can also provide moisture while encouraging birds to continue eating.
Watch closely for signs of heat stress, including:
• Panting
• Wings held away from the body
• Lethargy
• Pale combs
• Reduced egg production
If birds begin showing severe signs of heat stress, move them to a cooler area immediately and provide fresh water.

Keeping Pigs Cool

Pigs are especially vulnerable to heat because they have very few functional sweat glands and cannot cool themselves the way many other animals do. During Arkansas summers, preventing overheating should be one of the highest priorities for anyone raising hogs.
Provide plenty of fresh water at all times, and make sure waterers can keep up with increased demand during periods of extreme heat.
If possible, create a wallow where pigs can coat themselves with mud. Although mud may look messy, it acts as a natural cooling system and also helps protect pigs from sunburn and biting insects. If a wallow isn’t practical, sprinklers, misters or periodic hosing can help lower body temperatures. Be sure pigs also have access to shade so they can escape direct sunlight after cooling off.
Avoid feeding large meals during the hottest part of the day. An ideal time would be early in the morning or later in the evening when temperatures are lower, helping maintain feed intake and reducing additional heat generated during digestion.
Watch carefully for signs of heat stress, including rapid breathing, open-mouth panting, reluctance to move and animals piling around water sources. Heat stress can become life-threatening very quickly in pigs, so early intervention is critical.

Caring for Goats and Sheep

Goats and sheep generally tolerate warm weather fairly well, but prolonged periods of heat and drought can still create problems.
As pastures dry up, forage quality declines rapidly. Rather than allowing animals to overgraze, many Arkansas homesteaders begin supplementing with hay earlier than usual to protect both their livestock and the pasture itself.
Rotational grazing becomes especially valuable during dry weather because it gives grasses additional recovery time.
Sheep should be shorn before the hottest part of summer whenever possible. Removing heavy wool greatly reduces heat stress and improves overall comfort.
Even during dry weather, continue monitoring animals for internal parasites. Regular health checks and proper mineral supplementation remain important throughout the grazing season.

Keeping Cattle Comfortable

Cattle require plenty of water and shade to remain productive during Arkansas summers.
If handling cattle is necessary, schedule activities early in the morning before temperatures become dangerous. Avoid transporting livestock or performing stressful procedures during the afternoon whenever possible.
Many producers also begin feeding hay before pastures are completely depleted. While it may seem early, protecting pasture grasses from severe overgrazing often leads to healthier fields when rainfall finally returns.

Don’t Forget Minerals

Livestock often consume more salt and minerals during hot weather.
Keep loose mineral supplements available according to the needs of each species, and make sure mineral feeders remain dry and accessible.

Chickens

• Electrolytes (sodium, potassium, chloride) – Help prevent dehydration and maintain nerve and muscle function
• Calcium – Essential for laying hens to maintain strong eggshells.
• Magnesium – Supports muscle and nerve function during heat stress.
• Phosphorus – Works with calcium for bone and egg production.

Sheep and Goats

• Salt (sodium chloride) – Encourages water consumption.
• Potassium – Supports hydration and muscle function.
• Magnesium – Helps prevent muscle problems and supports metabolism.
• Calcium and phosphorus – Maintain skeletal health and milk production.
• Copper (goats only, unless sheep-specific mineral) – Goats require more copper than sheep.

Cattle

• Salt – The number one mineral during summer.
• Potassium – One of the first minerals cattle become deficient in during prolonged heat.
• Magnesium – Supports muscle and nerve function.
• Calcium and phosphorus – Necessary for growth and milk production.
• Trace minerals: Zinc, selenium, copper, and manganese support immune function and hoof health.

Pigs

• Sodium
• Potassium
• Chloride
• Magnesium

These electrolytes help maintain hydration and support normal muscle and nerve function.

Watch Pastures Carefully

Drought affects more than just the animals.
Walk your pastures regularly to monitor forage conditions. Overgrazed fields recover much more slowly after rainfall, and damaged pastures may take months—or even years—to regain full productivity.
If rainfall remains scarce, consider reducing stocking rates temporarily or providing additional stored forage.

Recognize Heat Stress Early

Livestock that are struggling with excessive heat may show several warning signs, including:
• Rapid or labored breathing
• Heavy panting
• Excessive drooling
• Weakness
• Loss of appetite
• Staggering or collapse
Move affected animals into shade immediately and provide cool—not ice-cold—water. Severe cases should be evaluated by a veterinarian as quickly as possible.
