Hurricane prep, post-event guidelines for livestock

Experts are encouraging livestock owners to take precautions as Hurricane Alex approaches Texas, as well as providing advice on livestock safety in its aftermath.

Weather reports indicate Alex could cause severe weather in many counties and associated rains could lead to flooding in many parts of the state.

"There are several measures that can be carried through in advance to minimize the threat of potential losses to a livestock operation," said Dr. Jason Cleere, Texas AgriLife Extension Service beef cattle specialist in College Station.

Livestock owners with large numbers of animals not capable of being evacuated by trailer should get animals to high ground, Cleere said. Open gates to pastures as cattle and other livestock instinctively seek higher ground.

"Cattle can also be physically driven out of low-lying areas and to higher ground to avoid a flooded area," he said.

Avoid putting animals in barns or other dwellings due to potential high winds, he added.

"Turn them out into large lots, pens or pasture,” Cleere said. “They can seek cover on their own in brushy areas.”

Livestock owners who own small numbers of animals which can be evacuated by trailer should make sure tires are properly inflated and flooring is in good condition.

"Don’t overcrowd the trailer. It’s best to leave some behind rather than have one go down and get hurt."

Prior to leaving the ranch, pick up debris that might become a hazard in the event of high winds. Strap down feeders, trailers and other items that might blow into a barn, home or other dwelling. And make sure there is adequate feed and water for a couple of weeks.

If there is substantial flooding, cattle could become stranded and forages may be ruined, Cleere said. In such instances, supplemental sources of feed may be necessary.

"Hay is important," he said. "Basically, hay can be self fed and cattle can sustain on their own for a period of time. Also, think about water sources. Make sure those animals have sufficient sources of good water."

Meanwhile, Cleere said, livestock producers can find hurricane preparedness and recovery information on the Texas Extension Disaster and Emergency Network, Texas EDEN, at The EDEN website has information on disaster preparedness and recovery.

"After the hurricane, danger to livestock can come from several sources," said Dr. Joe Paschal, AgriLife Extension beef cattle specialist in Corpus Christi.

After a hurricane, danger to livestock comes from drowning due to storm surges and accumulated rainfall. Injury can occur from flying debris or electric shock from downed power lines, he said.

As soon as it is safe, livestock owners should check on the condition of their animals and move them out of flooded areas onto dry or covered areas if possible. Then check for injury and render first aid for minor injuries to livestock.

"Be prepared to render some form of aid until the veterinarian can arrive," Paschal said. "Remember they may have damage to their homes and buildings or livestock, too, or they may have more urgent cases to attend to first. When you call the veterinarian, be explicit in the description of the injury and provide as much detail as possible."

Stressed animals should be given clean feed or hay and water, he said. Animals that have not had access to feed for one or more days should be given a little feed the first few days, gradually increasing it over a week to full feed.

Animals that eat hay should be allowed access to clean hay even if it is wet, he added. And watch for signs of sickness. Pneumonia will most likely develop if the animals have been in water and cold. Listen for coughing, look for runny noses, crusty eyes, hard breathing and lowered heads, and get treatment for these animals as soon as possible, he said.

"Do not feed wet or moldy feed to any animal," Paschal said. "Wet hay, as long as it is not moldy, will be good filler. Dry feed will be best for all classes of livestock, but give all feed in moderation."

High water will drive venomous snakes to higher ground as well.

"Usually, animals are bitten on the head or neck area, but smaller livestock can be bitten anywhere on their body the snake can reach," Paschal said. "Smaller animals are more susceptible to snakebite since the dose of venom is greater relative to body size. If you suspect snakebite on a small animal contact your veterinarian quickly."

Venomous spiders are also of concern, but most of their bites are not fatal to livestock.

"External parasites, especially mosquitoes, will be a major problem," Paschal said. "A number of commercial products are available for treatment of individual animals or small areas. However, for larger livestock, their only relief will be dry pastures with access to a good wind. The best defense is to ensure livestock are vaccinated against the major diseases or given a booster as soon as possible."

Paschal said several commercial products are available to apply to livestock to combat the ticks that also move to higher ground and onto more livestock.

"Internal parasites may become an issue over time, especially if cattle from several sources are commingled and many pastures are flooded," Paschal said. “This will not be an immediate problem due to the extended lifecycle of most of the internal parasites. You should visit with your veterinarian about future treatment."

Water quality in populated areas will also be an issue, he said, especially for livestock that drink from streams, bayous and tanks that fill with rain runoff. If possible, water livestock from cleaner water sources until these can be evaluated.

"If there are dead animals on your property, they need to be disposed of properly if possible," Paschal said. "Dead animals cannot be burned without permission of the Texas Environmental Quality Commission, but this might be waived in the case of a natural disaster.

"Usually one or a few animals can be allowed to decompose above ground if burial is not feasible, they are not a human health hazard and do not obstruct traffic, or are not in a waterway or drainage area."

To prepare for disasters, livestock owners should have an inventory list of their animals, identification numbers or photos, and any veterinary records that might be useful, as well as a first aid kit.

These recommendations are just a partial list of actions that livestock owners should be aware of in a post-hurricane event and do not cover several species-specific concerns, Paschal said.
