Initiating Spring Grazing

Spring has sprung, and that means that it’s time to prepare your horses and pasture for spring grazing. Here are some quick tips to keep in mind:

Is your pasture ready?

  • Check and repair all fencing and gates.
  • Check that water sources are clean and working.
  • Begin grazing when a majority of the pasture is 6 to 8” tall.

Are your horses ready?

  • Schedule annual dental care
  • Test manure to determine fecal egg count and deworm accordingly to reduce parasite load on the pasture.

Start grazing!

  • Start with 15 minutes per day.
  • Add 15 minutes each day until 5 hours of grazing is reached, then unrestricted grazing can begin.
  • Stop grazing when a majority of the pasture is grazed down to 3″ to 4” tall and rotate to a new pasture or dry lot.

Hoary Alyssum in Hay – Ask the Expert

Question
Hoary Alyssum in Hay

We suspect we have hoary alyssum in our hay. We’ve noticed our horses are stocked-up, but we are not sure if its from hoary alyssum or because all of the snow is limiting their ability to walk around. Can you confirm if this is hoary alyssym in our hay?

Answer

Yes, hoary alyssum is in this hay.

Circled in red you can see one of the seed heads in the photo.

 Small, oval seed pods that become translucent as they mature showing the small brown to black colored seeds inside the pods identifies this as Hoary Alyssum.

We recommend you immediately stop feeding the hoary alyssum-infested hay. Hoary alyssum only affects horses, so the hay can be fed to cattle, sheep and goats.

Horses react differently to hoary alyssum, but signs of toxicity are usually seen 12 to 24 hours after a horse ingests the plant.

Common signs include swelling and fluid build-up in the lower legs (e.g. “stocking-up”), a fever of 103F or higher, stiff joints, and an unwillingness to move. More severe cases can progress to laminitis.

Mild stocking up is most common; however, more severe signs can occur in horses eating hay with more hoary alyssum or when ingesting the hoary alyssum-infested hay for longer periods of time.

Clinical signs normally go away with supportive treatment 2 to 4 days after removing the infested hay. Horses with laminitis may take more time to recover.

Horse Drooling? Ask the Expert: Slobbers

Question:  My horse is drooling excessively and I’ve heard this is from eating clover. Will this hurt my horse?Horse Drooling

Answer:  Recently, there have been several reports of “slobbers” in horses. Slobbers, characterized by excessive salivation or drooling, is caused by a compound (slaframine) produced by the fungus Slafractonia leguminicola. Slafractonia leguminicola occurs on red clover.

Small black dots (as though dotted with a marker) on the underside of red clover leaves identify the fungus. The fungus grows best in hot, humid conditions and can cause slobbers when eaten fresh in pasture or when consumed in dried hay.

Although unsightly, horse drooling or slobbers is not a concern for horses as long as they stay hydrated.

Fall Pasture Precautions

Fall Pasture PrecautionsHorse owners should take precautions when grazing pastures after the first killing frost. Frost damaged pastures can have higher concentrations of nonstructural carbohydrates, leading to an increase in the potential for founder and colic, especially for horses diagnosed with Equine Metabolic Syndrome, laminitis, obesity or Cushings.

To reduce the chances of adverse health effects, we recommended horse owners wait one week before turning horses back onto a pasture after the first killing frost.

Horses should be removed from a pasture when a majority of the forage is grazed down to 4″. The entire pasture should then be mowed to 4″ (since horses do not graze uniformly), drug to disperse manure piles and the horses should be rotated to a different pasture or housed in a drylot. This time of year (fall), horses will likely need to be kept in a drylot due to limited forage re-growth.

Ideally, owners will slowly transition horses back to hay diet (from a pasture diet) in preparation for winter feeding. We do not recommend over-wintering horses on pasture due to plant damage from digging, pawing, and hoof traffic.

Finally, ingestion of dried or wilted (but not fresh) maple leaves is associated with the toxicosis. Toxicosis normally occurs in the autumn when normal leaf fall occurs. Red blood cell damage has been reproduced in horses ingesting 1.5 to 3 pounds of dried leaves per 1,000 pounds of bodyweight.

Horses are the only species for which maple leaf toxicity has been reported. Horses are often depressed, lethargic, and anorexic with dark red/brown urine after the first day of ingestion. They may progress to going down with labored breathing and increased heart rate before death.

Horses should be fenced out of areas where wilted maple leaves are plentiful. Although dried leaves may remain toxic for 4 weeks, they are not generally believed to retain toxicity the following spring.

Pasture Management – How to Prepare for Fall

Managing pasture can be a very important tool in controlling feeding cost for all livestock, including horses being kept on small acreages.  If pasture is going to provide a substantial amount of the required nutrition for a horse, it takes about 2-3 acres, per 1,100 pound adult horse.

Even with adequate acreage, weather conditions can limit pasture regrowth and decrease the amount of forage available.  Avoiding over-grazing is important for both the pasture and for the animals.   Keep the following in mind:

  1. Remove animals from the pasture when plants are grazed down to 3-4 inches in height. Grazing  too long and allowing animals to eat the grass off too close to the ground, will kill the grass and turn the pasture into a dirt lot where the only green plants are weeds, potentially requiring expensive renovation.   Also, if animals eat the grass too close to the ground on sandy ground, the risk of sand colic may increase.  Animals may also consume potentially toxic weeds if no other forage is available.
  2. If you have limited acreage, consider purchasing some temporary fencing so that you can rotate the pasture. The outer fencing should be a safe, permanent fencing.  You can cross fence the pastures with temporary fencing such as capped steel posts and appropriate electric wire.  By allowing the animals to graze one section, then moving them to another, total pasture yield can be increased substantially, helping to control total feed costs and improve pasture health.  Clip and drag the pastures after you pull the animals off to control weeds, parasites and flies.
  3. As pasture declines, you will need to adjust the amount of forage that is offered to maintain dry matter intake and nutrient intake. If the forage available is lower protein and lower energy than the pasture has been, you may have to adjust the concentrate portion of the diet. If you are using a ration balancer, you may need to move to the higher feeding rates.  If the higher feeding rates do not maintain Body Condition Score and Topline Score, you may need to switch to a different feed to allow higher feeding rates.  It is essential to monitor both Body Condition Score and Topline Score.
  4. Declining pasture quality can be a particularly serious issue for young growing horses, pregnant mares and senior horses.
  5. Make certain that fresh clean water is available at all times and that salt is available at all times. If you are not feeding a balanced feed or ration balancer, offer appropriate mineral free choice as well.
  6. If space is very limited, keep a dry lot area where animals can be fed and watered to prevent areas of pasture from being overgrazed.

Managing the pastures and selecting the right feeds as pastures change can help manage total yearly costs as well as improve animal health and condition.

Keep the Weed Seeds out of the National Parks, National Forests and National Grasslands

As horseback riders seek to take advantage of riding in the great outdoors, they need to be aware that National Parks, National Forests and National Grasslands will generally have a policy in place that any forage or feed that is brought into the area needs to be weed seed free.  Because there can be a hefty penalty, with fines up to $10,000 or 6 months of jail time,  it is highly advisable that riders check in advance the requirements of specific locations prior to bringing feed or hay into the location.

The North American Weed Management Association (NAWMA) has established the accepted standards for forage or unprocessed hay as well as for cubes and pellets made of forages.  The forage and unprocessed hay products will normally be identified by a bale tag or a twine of particular color.  The price for these products will normally be higher than for uncertified products.  Cubes and pellets will generally be identified by a certification tag indicating compliance with the North American Weed Free Forage Certification Program.

Riders can make a choice between long stem forage and pelleted or cubed products based on their feeding requirements and how the animals will be managed.

Commercially processed feed pellets and grain products that are processed by fine grinding along with heat treating and pelleting normally do not need to be certified as the processing is considered adequate to prevent the presence of viable weed seeds.

It is fairly common for riders to use both a certified forage/forage product and a commercially produced feed to meet the needs of animals while riding or packing into these great outdoor opportunities.  As always, free choice salt and fresh clean water needs to be a part of the feeding program.

The basic principle of not introducing any non-native or noxious weeds needs to be carefully implemented to preserve the wonderful riding opportunities that are available.

There are multiple options to consider as a trip is planned.  Various web sites can provide information about sources of forages in a given location.  The website www.trailmeister.com is a very useful resource as well as the state Crop Improvement Associations and the specific National Park, National Forest or National Grassland web sites.

Ask the Expert: Large Round-Bales


Different sized hay bales representing the benefits of large round-balesQuestion: We are having a hard time finding small-square bales and as a results, are going to start feeding round-bales. How many small square-bales are in a round-bale?

Answer: It depends on the weight of both the large and small-square bales. For example, if the round-bale weighs 1,000 pounds, then 20, 50-pound small-square bales would be equivalent to 1 round-bale. If the large round-bale weighs 1,200 pounds and the small-square bales weigh 40 pounds, then 30 small-square bales would be equivalent to 1 round-bale. It important to know the weight of hay bales both for feeding and economic purposes.
Keeping in mind that storage and feeding losses associated with round bales are typically higher compared to small square bales. Especially when storing bales outside and feeding without a hay feeder.

At Nutrena, we believe proper nutrition plays the biggest role for a lifetime of health and happiness for every horse. Nutrena formulates horse feeds specifically for every life stage and activity level, ensuring optimal nutrition.

Estimating Winter Hay Needs – Ask the Expert

Estimating Winter Hay NeedsQuestion:  We recently purchased a farm and will be housing our two quarter horses over the winter; they will not be ridden during the winter. Because I’ve always boarded my horses, I’m not sure how to estimate how much hay I will need for the winter.

Answer:  An adult horse at maintenance will consume between 2 – 2.5% of their bodyweight in feed (hay and grain) each day. For example, a 1,000 pound horse fed a 100% hay diet would consume 25 pounds of hay each day (using the 2.5% recommendation). From October 15 to May 15 (when there is no pasture in MN), the horse would consume about 5,350 pounds of hay or 2.7 tons. This would equal 107, 50 pound small square bales or six, 900 pound round bales during this time. For two horses, this amount would be doubled. It is critical to know the weight of the hay bales; not all bales weigh the same.

If the same horse was receiving five pounds of grain each day, their hay needs would be reduced to 20 pounds each day. From October 15 to May 15 the horse would consume about 4,280 pounds of hay or 2.1 tons. This would equal 86, 50 pound small square bales or five, 900 pound round bales during this time. Again, double this amount for two horses.

These estimates assume good quality hay is fed in a feeder to reduced hay waste. When feeding small squares-bales, hay waste when a feeder was not used (hay fed on the ground) was 13% compared to only 1 to 5% when a feeder was used.  When feeding large round-bales, not using a feeder resulted in 57% hay waste compared to 5 to 33% when a feeder was used. It’s always best to purchase extra hay to account for waste and because horses may require additional hay during the cold winter months.
