Ask the Expert: When to Start Grazing

Question:  I’ve heard conflicting recommendations on when to start grazing my horses.   Is April 1st too early to start grazing?
 
Answer:  Spring grazing should be introduced slowly and delayed until grasses reach 6 to 8″ to optimize both the health of the horse and pasture.  Calendar date is not important as weather conditions and grass growth can very greatly from year to year.

When pastures reach 6 to 8″, begin grazing for 15 minutes, increasing the grazing time each day by 15 minutes until 4 to 5 hours of consecutive grazing is reached. After that, unrestricted or continuous grazing can resume.

We also recommend feeding horses their normal hay diet before turning them out to pasture during the first several grazing events of the year.  This strategy should help avoid rapid intake of pasture grasses.

Even though hay and pasture are both forms of forages, there are significant differences. A gradual change from one feedstuff to another provides enough time for the microbial populations to adjust, reducing the chance of colic and laminitis.

Poisonous to Horses: Plants

As a horse owner, I have come to realize that horses have an uncanny ability to get themselves into trouble.  Whether it be messing with the fence, making play-things of their stall or breaking into the feed room to grab an extra snack, if we don’t want them to get into it, horses seem to find a way to get into it!  If lucky, the vet doesn’t need to be called, but there is usually some upgrading of hardware, the perpetual fixing of the fence or continuously beefing up security around the feed room.  But what about the things that we as humans haven’t built?  What naturally occurring perils of danger will my horse find and get himself in to? 

Pasture grazing is ideal for horses

As Winter fades and Spring makes a welcome entrance, thoughts turn from feeding hay to blissfully sunny pasture turnout.  Now is a great time to educate yourself about plants that can harm your horse.

March is poison prevention month and as horse owners, knowing what plants are poisonous to your horse can go a long way in preventing trouble.  To help get you started, here is a good resource of information about poisonous plants that grow in the Midwest, from the University of Minnesota Equine Extension Office.

If you find plants of poisonous varieties where your horse can access them, please work with your local extension office on methods of controlling exposure.  Also remember to check your garden and landscaping as many plants listed are popular decorations.

It is also important to note that plant variety growth varies by geographic region so be sure to check with your local extension office for information specific to the area in which you live.

So while you may not be able to keep them from breaking the fence, breaking into the feed room (despite the keypad lock on the door) or dismantling the components of their stall, you can be aware of and have a plan to manage the poisonous plants that dare grow near your horse.
