Water Requirements for Your Horse

A stable owner was in the office last week, and in the course of conversation, he said that he was almost to the point of not liking horses.  After more discussion, this was more related to the effort needed to keep clean, fresh water in front of them than anything else.  As most folks already know in North Carolina, it has been unseasonably cold.  This has caused watering systems that normally make it through the winter with no problems to freeze up.  Thawing our drinking cups, water troughs, or chopping holes in ice are not usually needed around here, but that has become chore number one on the daily jobs list for a lot of horse owners.

Let’s review the water requirements for horses.  According to the Vet College at UC-Davis, a 1,000-pound gestating horse needs at least 8 gallons of water per day.  The chart below shows the minimum requirements for different size horses and different levels of activity:


Minimum Daily Water Requirement for Horses of Various Weights
Resting/Normal Environmental Temperature
Heavy Workload (double to triple resting requirement)
Gestation/Lactation (add 30% to resting requirement)
High  Heat and Humidity (double to triple resting requirement)

500-lb horse

3 gal per day

6 to 9 gal per day

4 gal per day

6 to 9 gal per day

1,000-lb horse

6 gal per day

12 to 18 gal per day

8 gal per day

12 to 18 gal per day

1,500-lb horse

9 gal per day

18 to 27 gal per day

12 gal per day

18 to 27 gal per day

2,000-lb horse

12 gal per day

24 to 36 gal per day

16 gal per day

24 to 36 gal per day


Cold weather does not drop the amount of water needed by horses.  Please note that the figures presented are minimum requirements.

Also, please remember that the water should be clean.  Many times, horses will refuse dirty, stagnant water until they are in dire need – and then only drink a minimal amount.  Dirty, stagnant water/water troughs/fountains can also be a source of bacterial or viral infections, so there is some extra incentive to make sure that the water systems are in top shape.


Other writers for this blog have mentioned the danger of impaction colic, so I’ll just say that avoiding this problem makes the chore of keeping fresh, clean water even more important.  A bit of heat for the water makes it easier to drink, so horses will consume a bit more than if left cold.

It is recommended that horses be watered at least twice a day; preferable, horses should have continuous access to fresh, clean water.  If the water lines in the barn are frozen, the buckets of water taken to the horses twice a day will be greatly appreciated by your equine friends.

Preparing for Successful Foaling



That time of year is coming! Soon you will be hearing the pitter patter of little hooves! Are you ready? Is your mare ready?
Believe it or not she is probably more ready than you are. Nature has a great way of taking care of its self no matter what we do, but it’s always good to be prepared!
Dr. G. Marvin Beeman, DVM of Littleton, Colorado, says that the gestation period for a mare is 320 to 365 days, with 340 days accepted as the average. So keeping proper records of breeding times is important and part of helping you to be prepared.
You will have helped her along the way by seeing that she had proper nutrition, increasing her feed in the last 90 days, but still kept her weight gain to a minimum as overweight mares can have trouble foaling. You have made sure to follow the vaccination schedule prescribed by your vet, had her teeth checked, and have been getting her exercise. Moderate, consistent exercise can help avoid problems with ventral edema, the collection of edema (fluids) from the udder forward, sometimes as far as the front legs.
As your mare gets closer to foaling, she will begin to have physical changes that you can use as your guide to her progress. At about 3 – 6 weeks before foaling, the mare will start to develop her udder, and 3-4 weeks before foaling the muscles and ligaments in her pelvic area will start to loosen, making way for the passage of the baby. This can be especially noted around the tail head about 12 – 24 hours prior to foaling. The vulva and vulvar opening swell and increase 2-3 times in size during this last 12 – 24 hours as well. There may also be a small straw-colored, semi-hard droplet discharge on the udder, not to be confused with waxing.
What is Waxing? Waxing is the process in which a variable-sized, horn-colored waxy substance forms at the end of each teat. While not every mare waxes, most do and it most often occurs 24 to 48 hours before foaling.. The waxy substance remains for 12 to 24 hours, then softens and falls away in a viscous stringy form. Then milk (colostrum) begins to drip from the teats. If your mare starts dripping colostrum early you will need to consult your veterinarian about the possibility of supplemental colostrum at the time of foaling.
Do you know the stages of foaling?
1) The preparatory phase – often looks similar to colic. Mares will be restless, nervous, uncomfortable, paw the ground, look at her side and even kick at her abdomen. She will often break into a sweat on her flanks and neck and occasionally her entire body. This stage may last from one to four hours. This is the time to wrap her tail and clean her, and separate her from other horses.
2) Actual labor – The water will break, and then you should see another sac with the front foot in it, closely followed by the second front foot, soles pointing down. If you don’t see this, call your vet. Once the foal starts coming, the mare will have three to five strong expulsive efforts, followed by 2 to 3 minutes of rest. A foal stays on its back until the actual foaling process begins. Then, during labor, the foal's body twists so that the forelegs and head turn over as the foal advances up and out of the mare's body. The back legs and rump usually stay in and upside-down position until the foal is actually being delivered. This helps the foal to maneuver up and over the pelvic bone shelf. Particular effort is required for the foal's shoulders and hips to clear. Normally, all of this should not take more than 45 minutes after the water bag breaks. If it takes longer consult your veterinarian. It is always a good idea to remind yourself of the foaling process in advance, just incase your vet can’t make it right away to your emergency. There are many step by step guides that give details as to how to pull when, but all of them have the same thing  recommendation - never pull mechanically, always use your own pulling power and pull only when the mare is straining to push. Once the foal is mostly out, everything is good and the foal is breathing well, leave the pair alone. This may be a time for the mare to catch her breath, and it is definitely time when the umbilical cord is still allowing blood to flow to the foal. Do not break the umbilical cord! The cord should break on it’s own. Only break or cut it at the direction of your veterinarian. 90% of the time it will break on it’s own. As soon as it does break you need to dip it into the naval dip. An unprotected naval is a gateway for infection from the outside surroundings.
3) Expulsion of the fetal membranes - Most of the time, a mare will "clean" (shed the afterbirth) within 30 minutes. If she hasn't done so within 3 hours, call your veterinarian. The condition of those membranes also indicates any presence of disease, infection, or edema, which will help determine if the mare should be bred back on her foal heat.  The membranes should be examined (by you or your vet) and made sure to be whole. The expelled membranes (afterbirth) will look very much like a pair of pajama bottoms with the feet in them. If you are unsure what to look for have your vet check the membrane.
Do you have your foaling stall ready? Do you need a foaling stall?
Whether you prefer a clean pasture or foaling stall is personal preference. Both work great, but weather can be a determining factor, and you may want to have both ready. The things both choices should have in common are that they be clean and free of obstacles that might harm the foal as it is trying to stand and walk, and preferably the mare will be by herself. If you choose to pasture foal, make sure the fencing is such that the foal is contained and the mare will not be harmed if she were to lay down close to it and inadvertently put her legs through it. 
The foaling stall should be clean, draft free, dim lighting is suggested, bedded with straw to reduce dust for those little lungs. If you don’t have a way of dimming the lights, start leaving the lights on a week or so before the due date. This gives the mare time to get used to the light.
Once the foal is on the ground, the mare should stand and you need to leave the stall. This is their time to get aquainted. The nuzzling and licking stimulates the foal to get up and activates the sucking reflex. When trying to get up they will stumble and fall, probably more than once. But you need to leave them alone. This is why it is so important to make sure the foaling area is clear of obstacles that can hurt the foal.
Have you got your foaling kit ready?
What’s a foaling kit? A foaling kit is a collection of things that you might need to help with the foaling of your mare. Placing everything in a box, bag, container of some sort to make it easier to take to the stall, and making sure it’s all together where you need it. Here are a few items for a foaling kit as suggested by Cherry Hill.  Just like most things, it can be tailored to fit your specific needs.
Vet's phone  number(s)
Cell phone - if no phone in barn – having a cell phone can combine a number of these items.
Camera (I like my digital camera phone as it takes great pictures WITHOUT a flash so as not to disturb mare and foal and I can post them or send them out to announce the arrival!)
Flashlight and fresh batteries
Clock or watch to keep track of intervals
Notebook and pen to take notes of events – make notes of when the stages take place so if you have to answer questions to your vet, you have the answers and don’t have to think about it in a possibly stressful time. Also they may be a good reference for next year.
Book - The Complete  Book of Foaling by Dr. Karen Hayes, DVM
Lots of clean towels (various sizes) – hopefully you won’t need these as it is the mom’s job (and is part of the bonding) to clean the foal, but it’s good to be prepared and with some new mom’s they don’t know their job and sometimes the weather can play a factor. If it is especially cold you may want to dry the baby faster to avoid stress.
Ivory or other mild liquid soap – used to clean mares hind quarters and bag – make sure to rinse with warm water
Iodine/Nolvasan (chlorhexidine) navel dip and container to dip navel in (I use a syringe case) – ask your vet their preference
String/scissors/knife – enough string to use for tying the umbilical cord if necessary and to tie up the afterbirth before it is discharged and the scissors or knife to cut the string or break the placental sac
Tail wrap – to be put on the mare in advance of the birth and helps to keep her clean. You may want to use a disposable wrap such as Vetwrap so you can just throw it away after the foaling.
Enema – warmed if possible, even if it’s just by sticking it in your pocket. The enema ensures the passing the foal’s first feces, called the meconium
Ky jelly – use on the enema applicator to ensure you don’t harm the foal’s delicate bowels
Obstetrical sleeves / sterile gloves
Clean buckets – good for collecting dirty towels or getting clean water in
Muck bucket and/or garbage bag for the afterbirth - feed bags can work for this too, I like something disposable so you can just pitch the whole thing in the trash.
Hopefully this collection of reminders about the birth process and the different stages, and the foaling kit list will help make your foaling experience a good experience and happy memory. It basically comes to like most things in life, you need to be prepared. Having a good vet, and discussing with the vet what you will do in case of an emergency will be the best way of being prepared. Knowing your limitations is probably the best way to help your mare. When in doubt call your vet.

Equine Infectious Anemia (EIA)

Do you know what Equine Infectious Anemia (EIA) is? EIA is an infectious, viral disease found in equids. Do you know what the symptoms look like or what to do if you suspect your horse has this disease? This disease can occur in varying forms, such as acute, subacute and chronic. Blood samples can be tested by sending them to Rollins Diagnostic Lab in Raleigh, NC. The North Carolina Department of Agriculture has a fact sheet on EIA where you can get all of your questions answered. Click on the link below to read through the fact sheet. Contact your local Cooperative Extension agent or your veterinarian if you have more questions.

What's Up, Buttercup?
and other troublesome weeds for this time of year

There are a number of weeds that laid low in the fall and are now or soon to be becoming more noticeable. Here are a few of them with some ideas on how to identify them.

1. Buttercup
  • Perennial, flowers are bright and shiny yellow with a single flower on a stalk.
  • bulbbutr2.jpg (184811 bytes)

  • Identify when plant is young as lobed leaves, thickened stem base (there is sometimes a bulb-like form at the stem base) and occasionally hairy stems
  • It will seem like nothing is there and suddenly there's this really big field coated in this glossy yellow flower. It was there for awhile, just making a low profile.






2. Henbit 
  • Annual with square-ish stems and "pretty" purple flowers (as soon as someone says "pretty purple flowers" in the winter I think of henbit)
  • Leaves look frilly -- they remind me of a pretty shirt collar
  • Fibrous root system, plant grows in a clump
  • Leaves often darken as plant matures

3. Chickweed



  • Chickweed is an annual (common chickweed) or perennial (mouseear chickweed) that is often found alongside henbit. Think of them as best buds.
  • Flowers are small and white and leaves and stems may be hairy, depending on the type of chickweed.
  • Tip of the leaf may be more pointed in some types of chickweed than others (hairier chickweeds are normally more blunt on the leaf tip)

There are often different types of any weed in one area. Contact your local NC Cooperative Extension Agent for additional help in weed identification and in help on weed control. Herbicide options will depend on the crop and weed maturity. Proper identification is critical to proper control. A reminder that weeds may be further along in one area than another so you may see some henbit flowering now in one pasture but may not see it flowering in another or you may not see them all flowering at the same time.
