Daylight savings time is here once again, and with it, the arrival of warmer weather. Spring means greener grass, flowers, and budding trees—so many of the things we horse people enjoy.
However, due to quick-growing grass, spring can also spell danger for some horses—especially those that are insulin resistant, have Equine Metabolic Syndrome, or Pituitary Pars Intermedia Disorder (PPID/Cushing’s Disease). For horses that have been off pasture all winter, spring grass can also lead to colic. Put simply, spring grasses can wreak havoc on a horse’s digestive system and metabolism.
Spring grass is different from grass growing in other seasons because of the quick growth spurts (especially after periods of rain). It also tends to be high in non-structural carbohydrates (NSCs). Cool season grasses such as timothy, orchardgrass, tall fescue, Kentucky bluegrass, and perennial ryegrass are of most concern this time of year.
Tips for Transitioning to Spring Grass
To help ensure that your horse has a smooth transition to spring grass, here are a few tips:
- Begin with 10-15 minutes of turnout and increase grazing time in small increments each day to allow your horse to gradually acclimate to green grasses.
- Feed hay before turnout to curb your horse’s appetite and keep him from overeating. This will also help your horse transition from hay to pasture.
- Use a grazing muzzle in order to restrict grazing. This is especially good advice if your horse is prone to laminitis.
- Monitor your horse daily. If you observe unexplained lameness, heat in the hooves, or signs of colic, remove your horse from the pasture and call your veterinarian immediately.
- Some high-risk horses may need to be kept off spring grass altogether and instead be kept in a dry lot (and fed hay) to avoid laminitic episodes.
Supplements for Horses on Spring Pasture
There are several supplements that are good to feed in spring as your horse transitions to the greener grass. Of course, they can also be fed year round.
1.) ProGuard Probiotics contain three lactic acid “good” bacteria strains which promote healthy digestive function. Good bacteria help the body make important B vitamins, while also maintaining a strong immune system.
2.) Icelandic Organic Kelp is the highest quality kelp available. It is 100% organic and contains 60 trace minerals, micro nutrients, and amino acids as well as many natural vitamins. Many of these nutrients may be missing in spring grass. Kelp can help boost the immune system, balance hormones, and lower high blood cholesterol levels. Because it contains plentiful iodine, it is extremely healthy for the endocrine system and is a great choice for horses with Equine Metabolic Syndrome, Cushing’s Disease, and Insulin Resistance. It helps control the thyroid and regulates metabolism. Kelp is also very beneficial for horses with hypo-thyroidism.
