Divide and Conquer – Pasture Management Tips

Are you tired of looking at weedy paddocks and dusty dry pastures? Is your current pasture management up to scratch?

Attention to pasture management is huge part of equine care. Regardless of whether horses are housed and grazed at a smallholding, homestead backyard or enjoy access to huge tracts of land available on ranch land spreads, the health of every horse fundamentally includes the need for access to grass.

Whatever the horse owner has available for their horses’ dining delights, good pasture management can make all the difference to the health of their charges.

How can you improve the pasture available? It’s simpler than you might think. Divide and conquer! Here’s a few tips to help you along:

Dividing Fences Must be Safe

Division of pastures provides many benefits to the overall quality of the grazing land. However, be aware that simply adding a line of electric wire fence down the center of an existing fenced field may not offer the best solution if you intend to pasture horses on each side at the same time. Plan for future needs when you install fence lines. While you may not intend to pasture horses next to each other right now, you may wish to do in the future.

Division of pastures between equine neighbors should always offer safety first and sturdy double fencing is a sure-fired way to eliminate the endless challenges horses will dish out to each other when bored with eating grass. The old adage, “Good fences make good neighbors,” could be applied to horses as well as humans.

The initial extra expense for double fencing versus single fencing can be cheaper than the cost of treating injuries (which could be life threatening), that may ensue when horses ‘get into it’ over a shoddy fence. Damaged fences also require constant maintenance involving additional costs in labor and material.

The Nefarious Worm Population

While most horse owners deworm their horses on a regular basis, worm resistance to equine deworming products that are currently available on the market is becoming alarmingly common. This is a topic I have personally researched and written much about. There are many resources on fecal worm counts and other methods of worm control in horses and its well worth understanding the implications of the resistance to dewormers affecting our horses’ health.

The traditional idea of harrowing pastures in Spring and Fall in colder climates, to expose worms to frost in order to mitigate their life cycles is actually not the best time to harrow a pasture, if harrow it you must. Frost does not kill all worms. Cystic stage worms require moisture to survive and the heat of a summer day is the better time to harrow as the breakdown of the cysts will deny the larvae the necessary moisture to survive.

The best method to keep down the worm population on a pasture is manure removal.

Obviously once the pasture has been mown down and harrowed over, the field should be not be grazed right away to avoid ingestion by the horse of grass stems contaminated with the various life cycle stages of worms.

The division of large parcels of pasture into smaller ones will facilitate the option to rest or fallow the affected area.

All Horse Farm Management Should Feature Fallow and Rotation Methods

Overgrazed land offers significant health issues to horses of all ages and not just in regard to worm counts. It can also trigger metabolic disorders, particularly when the grass becomes very short. This is especially common in older horses and certain breeds of equines prone to such health issues and the Fall season brings with it a particularly risky period for horses subject to these disorders due to the high sugar content of short grass.

Overgrazed land also gives the soil and grasses no time to recover. Bald patches of dirt will quickly become overrun with weeds that can quickly spread via rhizome activity. A horse may avoid ingestion of a toxic weed or plant if it is not dry and is in full growth, given it has access to plenty of other more palatable grazing options. But when a horse is hungry and choice of grazing is limited, the weeds or other noxious invasive flora are much more likely to be ingested.

An overgrazed, weedy pasture is not just unsightly. It can quickly turn to mud during Spring rains, and thus provide the perfect environment to encourage health issues for the equine occupants such as mud fever, pulled tendons and ligaments, not to mention a giant grooming headache.

Fields Need Feeding Too

Before the pasture becomes overwhelmed with horse traffic it is wise to rest it. Removal of the avid equine grazers to another space, soil testing and replenishment of the land by feeding it appropriate nutrients to keep it pH optimized for grass growth based on science, will keep the pasture healthy for further use.

Diligent management of the fields before bare areas of ground appear and grass becomes overgrazed is actually cheaper in the long run than waiting until the damage is done. Grass reseeding, overseeding and even weed eradication all cost considerably more than a lime or fertilizer feeding of the soil. Seek advice from your local extension office or farming cooperative for soil testing, ground preparation and horse pasture seeding and care and be prudent about what chemicals or additives you introduce and ensure there is no likelihood of lingering toxicity in the pasture that would affect the health of the horse.

Herd Management

Difficulties with herd management are easily averted with the provision of multiple paddock/pasture division options. Behaviors such as an overly zealous gelding’s attention to a mare, infighting between mares coming into season, an older horse being bullied by a younger equine etc. can all be easily managed with separation and reorganization of the herd dynamic.

Large or Small?

If you have a horse breeding operation where you are foaling out mares each year, provision of a small turnout close to the barn is a boon as it allows easy daily access and an opportunity to observe the newborns or mothers-in-waiting close by.

Smaller pastures can also be beneficial as they can limit the movement of horses that require rehabilitation from disease or injury and are useful for the turnout of new arrivals, where time is needed to acclimate to an unfamiliar environment.

Larger pastures will be required for larger herds of horses, and are often set a distance away from the barn if 24 hour turn out is provided and daily in/out handling is not needed. A minimum of an acre per horse is the general recommendation, although this all depends on the quality of the soils and pasture.

Dry lots can also be incorporated into the field design for horses with metabolic issues or diseases that require limited or no access to grazing such as laminitis, Cushing’s disease etc.

There are a multitude of products available on the market to surface the dry lot that will keep it dust and mud free throughout all weathers. This can alleviate the risk for sand colic and mitigate other health issues than can arise in a dry lot such as deep mud.

A paddock set apart from the other paddocks for quarantine purposes is also a useful adjunct to a barn pasture set up.

Weather Worries

Regions of the country that experience heavy snowfall or inclement weather provide challenges for horse care with snowbound paddocks and access for feeding.

Paddock gates set higher than ground level to facilitate opening without the need to plow, compacted gravel/stonedust surfaces in and around the entrances to the turnout space and multiple pastures fanning out from the main barn area can be helpful in providing easy ingress and egress during challenging weather.

The Need For Shelter

It should go without saying that all pastures large and small, should offer more shelter for the equine occupants than that provided by a large ‘lightening attractive’ tree or hedgerow.

Run-in sheds should be placed with their front, open side away from prevailing winds.

Some prefabricated run-in sheds offer tow hooks on each end of the structure that are extremely useful for moving the building around with a tractor if it becomes necessary in the future.

It is always safer to go wider rather than deeper in run-in shed design. This will help eliminate one horse being able to bully a compatriot by confining it to a corner of the structure. The same reason curves on fenced pastures are better than corners when it comes to horse safety.

If you have a big horse herd it is better to add multiple run-in sheds versus one extra large one. These structures will offer a retreat for horses lower in the pecking order from dominant ones within the equine group.

Placement of the run-in sheds should also be carefully considered. If placed in the center of the fields away from fence lines, the structure will be accessible by the horses on every side. Thus drainage from the roof, height of the lower aspect of the roofline, and siding material used (preferably not metal that a horse can kick through resulting in significant injury), are all factors to carefully consider.

If possible place run-in shed where you can see inside the structure from the gate or entrance to the field, so your visual horse health check can be easily made without entering the pasture during the day.

Remember run-in sheds like horse barns will require regular clean out, so allow for easy access and decent proximity to your yard where available.
