Equine Management Program

Now is the time to register for the fee-based Equine Management Program. 

A properly managed pasture reduces feed expenses, promotes overall horse health and reduces environmental concerns.  The equine management program aims to optimize the use of Iowa horse pastures and includes a farm visit from Iowa State University staff; area soil map, soil analysis, and fertility recommendations; forage quality analysis and plant species identification; weed control recommendations; manure management recommendations; an overall facilities assessment; and a customized pasture and grazing management plan.

Health Problems Caused by Floods

by Peggy Miller 

ISU Equine Extension Specialis 

Lots of rain and standing water can increase the incidence of mosquito-borne diseases. These include eastern and western encephalomyelitis and West Nile Virus. To prevent these diseases make sure your horses are up to date on vaccinations.    

If the pasture has flooded and been under water clear the pasture of debris. Check the fence to make sure they are intact. Floods bring trash, broken limbs, trees which can be potentially dangerous to horses. Make sure rotten hay and vegetation is removed. Both of these can mold and could potentially be toxic to horses if they eat either. 

Horse's hooves tear up wet pastures more so than other livestock. This may result in more weeds compared to grass. The horses in this situation may require hay in addition to the pasture to meet their requirements


Sacrifice Areas  

by Peggy Miller
ISU Equine Extension Specialist


To save your pasture you should have a sacrifice area. a  A sacrifice area is a small paddock or exercise where horses do not graze. The area can be used during winter, the rainy season or whenever you need to keep horses from compacting, trampling and overgrazing pastures.

The goal of a sacrifice area is to design it where mud is minimized. The size depends on the number of horses but should be kept to a minimum. Areas can range from small areas (20' x 20') to long narrow paddocks (12' x 100'). Place the area on high ground in an area with good drainage. Any drainage from the area should go into a buffer area. The area should have access for horses to fresh water and a shelter or wind break.

Construction of the area should consist of the dirt base. Geotextile fabric can be placed over the dirt. This fabric allows water to pass through but does not allow sand or silt to migrate up. This keeps your footing from sinking into the soil over time. The footing should consist of compacted gravel or sand. The size of the gravel should be 3/8", 5/8" or 7/8" and six inches should be applied. Advantages of gravel are it is easy to pick up manure, has a long term material life and will form a hard, durable surface. Disadvantages include expense, horses will find it difficult to roll on and some will turn up in a manure pile. For sand, apply 8 to 12 inches. The benefits of sand are that manure is easy to pick up; it allows for drainage and has a long term life. Disadvantages include expense and sand is not good to feed horses on.

Benefits of a sacrifice area include having an area where horses can get out of the mud, having healthy pasture, having the ability to set up a rotational grazing system for pastures, ease of manure removal and improved property value due to improved aesthetics. The biggest disadvantage is the expense of setting up a sacrifice area. However, if constructed properly they require little maintenance and can be used whenever your pastures are muddy, under renovation or over grazed. This allows for healthy pastures that can be more nutritious.

Horse Questions

  1. Is hay stored in a barn for a year or more nutritious? As long as the hay has been stored in a dry environment, the only nutrient lost is Vitamin A and this occurs in the first 6 months of storage. Other nutrients such as energy, protein, calcium, phosphorous etc. remain basically the same even after 2 years of storage. Over time hay will loose its fresh smell but this will not affect the nutrient value.
  2. When are sugars the highest in pasture plants?  

Levels of NSC will be lowest from about 3 AM to 10 AM. NSC peaks in afternoon, and will start to decline after the sun goes down.

Mid- to Late- May 2013 Hay Price Update

These are hay prices paid at auction in the recent past weeks. Much of the price information is obtained from USDA Hay Market News. Personal contacts of local Iowa hay auctions secured price information for these market outlets.  Auctions were chosen to reflect prices across Iowa. Other nearby auctions may exist. No endorsement of the listed auctions is intended.


The USDA Market News group uses the following hay classification designations in their market price reports. Of all hay sold, 1% or less would be designated in the 'Supreme' class. There is a general relationship between visual characteristics and forage analyses.  If possible, the following Hay test analyses ranges (on dry matter basis) should be used to establish the appropriate quality designation.

When feeding livestock, sample all forage lots and use forage analysis information for balancing livestock rations. Read More



Summer Workshops
Middle School and High School Summer Design Workshops

In partnership with Extension and Outreach, the College of Design is offering several  youth design workshops and camps for middle and high school students this summer in Ames, Sioux City and Storm Lake. Through hands-on design activities, participants will learn to solve problems creatively and express their ideas both visually and verbally. They will also learn about the many careers in the art and design professions.
