Managing livestock resources during natural disasters


Weather-related disasters, such as floods, winter storms, tornadoes or extreme temperatures that can last for extended periods of time are common in Michigan. Preparing for these events by ensuring animals have enough food, water and care can significantly impact the health, safety and well-being of your herd.

Preparing an emergency water supply

Water is essential for all animals, especially when disasters disrupt supply. In emergencies, dehydration can quickly become a significant issue.

  • Aim to store 3 to 7 days of clean water.
  • Livestock need about 1 to 2 gallons per 100 lbs. of body weight daily
  • For example, a steer weighing 1,000 lbs. will drink around 20 gallons of water.
    • Exception: Increased water intake occurs in lactating animals (cows, sheep, goats, etc.). A lactating dairy cow will drink 30-50 gallons of water daily.
    • Exception: Increased water intake occurs in times of high heat.

Always have a reliable water supply and multiple backup plans to supply clean drinking water from various areas.

Water purification

Floods and disasters can contaminate water. Have purification tools, like chlorine tablets or filters, ready. Do not use floodwater unless it has been purified, as it may be contaminated.

Managing food supply

Providing feed for animals during natural disasters is another concern. Having excess feed and being able to access areas where animals are located to provide feed is important to prevent malnourishment, illness, or death due to lack of adequate nutrition.

Stockpiling feed

  • Store enough feed for 3 to 7 days, up to a month.
  • Feed to keep on hand in excess may include hay, silage and grains.
  • Keep feed in a dry, off-the-ground, rodent-proof place.

Alternative feed

If regular feed runs out, keep alternative sources like grain silos or commercial feed blends available. Livestock supplements can also be useful. Work with local feed mills or feed stores to prepare for potential natural disasters or help bring in additional feed.

Managing pastures

If pastures or livestock areas where animals live are damaged during a disaster, you may need to feed supplemental feeds. Additionally, if you are in the middle of your birthing season, extra care must be taken to ensure newborns are safe and protected as much as possible from dangers. Having temporary or portable fencing could be a good option while the main pastures are disrupted, but have a solid plan of where to put this and make sure it is sturdy enough to hold all the animals in.

Handling food and water for different disasters

Each natural disaster is unique. Here is a quick breakdown of how to manage food and water during specific events:

  • Flooding: While floods can ruin your water supply and feed storage, remember that livestock are adaptable. Use stored water and dry feed like hay and silage.
  • Do not use floodwater unless purified. Your animals, with your support, can weather this storm.
  • Drought: Water and forage are scarce during droughts. Conserve water and stock up on feed for your livestock.
  • Wildfires: Wildfires can destroy grazing areas and contaminate water. Have plenty of stored feed and water, and make sure you can relocate livestock if needed.
  • Extreme Heat and Cold: In heat, livestock need extra water, shade and ventilation if housed inside. In cold weather, keep water from freezing and provide extra energy-rich feed and bedding.

Other tips to stay prepared

  • Monitor animal health: Look for dehydration, lethargy or signs of stress. Stress weakens immunity, so be sure to monitor animals frequently.
  • Backup power source: Purchase and maintain a backup power source, such as a fuel-powered generator or an equipment-powered generator you can run with a tractor. Have batteries and portable charging blocks ready to stay connected to community resources and news.
  • Create an emergency kit: Pack essential items like first aid supplies, medications and contact information for vets and local emergency agencies.
  • Stay informed: Knowledge is power. Follow weather forecasts and local alerts, and sign up for emergency notifications. By staying ahead of the curve, you can make informed decisions that will protect your livestock.

When disaster strikes, it is important to have the right resources to help your livestock survive, which requires preparation. By storing water and food and creating a solid disaster plan, you can minimize the stress and impact on your animals, keeping them safe and comfortable through the crisis.
