Rodent Control on Farms
Characteristics of Rodents:
● Behavior - rodents have a home range they spend most of their time in. Mice live in smaller territories ranging 10-25 feet. Rats range around 100 feet and live in colonies.
● Eating Habits - Rats usually eat their entire meal for the day at one time, usually at night while mice eat small amounts of food several times during the day. Rats are more wary of new objects, so it may take longer for success with bait stations and traps to be effective. It may take at least 5 days for the rat to accept the new object while a mouse may accept it overnight. Rats are also pickier eaters and like fresh food while mice are more curious and more willing to try new foods.
● Reproduction rates - rats can produce 10-12 litters per year with an average size of 6-8 babies. A single rat pair can produce 15,000 descendants in only one year! The reproduction rate for mice is similar with 5-10 litters per year with 5-6 babies.
● Front incisor teeth on rats - grow on average 5 inches per year, so rodents gnaw constantly to keep them worn down.
● Rats can climb both horizontally and vertically. They jump vertically as much as 36” from a flat surface and 48” horizontally from a flat surface. They can swim as far as ½ mile in open water and travel against sewer lines in substantial water currents. And this surprised me - they can drop 50 feet without being killed or seriously injured!!
Sanitation practices: minimize and clean up feed spills, mow around buildings/houses to decrease cover, throw away garbage frequently, and not stack lumber and other construction debris near buildings. Exclusion is a lot harder in the barn area themselves, but focus exclusion practices in offices, storage buildings and feed rooms. Exclusion includes sealing cracks or openings in the building. Leave no holes larger than ¼ inch. Doors, windows and screens should fit tightly.
Population control: trapping can be an effective way to control rodents. Trapping rats may require more skill and labor. The advantages to trapping is that it doesn’t rely on potentially hazardous rodenticides, success is visible, it allows disposal of carcasses, and can eliminate odors. There are several available traps which can be single trap or multiple-capture live traps.
Rodenticides (toxic baits): baits are formulated with an attractant and a rodenticide in them. Some baits may be restricted use pesticides (RUP) and require a pesticide license. Different types of rodenticides work in different ways to kill the rodents. There are situations where each type may be a better choice.
Bait stations with rodenticides and placement is critical. Using a bait station targets the rodents and allows them to feel secure while eating the bait. It also can help keep out other animals on the farm. Proper placement and maintenance is critical - keep in mind the home range of the rodents so you’ll ensure you have plenty of bait stations. Always wear gloves when putting out bait for your protection as well, as rodents will avoid the bait stations if they smell human scent on them. Bait stations can be purchased or made on your own.
Rodenticide formulations come as bar baits, concentrates, tracking powders, or pellets. The bar baits contain a rodenticide, a grain product, as well as a binder. The binder allows the bait to hold up during moisture events. These products are typically found as chunks or bars. It’s extremely important to read and follow the label instructions because all types of rodenticides are poisonous and can put other animals at risk that are not the target animal of the rodenticide. Be sure to read the manufacturer information and warnings.
To be effective in implementing a rodent control program, you must be monitoring and evaluating the program constantly. There are several reasons rodent programs may not be successful: not enough bait stations, the control area is too small, not enough exposure time to the bait, easy access to other food supplies, not stocking bait stations on a regular basis, choosing the wrong bait, moldy or old baits, and not rotating baits. It’s very important to properly handle rodenticides.
Predators: cats and even dogs can be a method of control, but in reality rodents may be attracted by the food left for the cats or dogs. They can catch some mice, but may not be able to keep up with them as they multiply quickly.
Prevention and good sanitation practices are critical to keep rodents out because it is hard to eradicate them if you have a problem. Knowing rodent behavior can help you determine what control methods may work best for you. If you have any questions about rodent control on your farm, contact your local Cooperative Extension office.

Foaling Checklist
Spring is full of life! The grass is starting to grow, pollen is everywhere, and foals are on the way. Having foals is exciting but can quickly become scary. The best way to prevent an emergency is to be prepared. Here is a checklist to help makes sure you are prepared.
Phone Number: Your emergency and normal veterinarians are saved in your cell phone and posted in the barn.
Make sure that your veterinarians know the relative due date of your mare. Do not hesitate to contact them if you suspect something is not going right.
Thermometer: the key to telling if the temperature of foal/ mare is normal, or if an infection is present
The normal temperature
Mare: 99-100 F (37-38 C)
Foal: 100-102 F (37.7-38.8 C)
Stethoscope: helps indicate heart and respiratory rates
Normal Heart Rate
Mare: 28-40 bpm
Foal: 80-120 bpm
Normal Respiration Rate
Mare: 8-16 bpm
Foal: 20-40 bpm
Scissors
Flashlight:
Charged batteries
Tail wrap:
keep the tail out of the way
Obstetrical (OB) Gloves:
check position or pull (if no progress)
OB Lube:
This is essential before checking the position or pulling
KY, J Lube, Livestock Lube
Exam Gloves:
handling placenta,
cleaning mare or foal
Liquid Soap
Umbilical tape or clamp
Umbilical cord disinfectant:
Iodine or diluted chlorhexidine
Towels
Colostrum
Frozen
Replacer
Make sure that you get colostrum replacers and not supplements.

Time for Spring Vaccinations
photo credit: thehorse.com
Has your horse been vaccinated this spring? Everyone has their own system and situation, but we all should meet the "must dos" on our vaccine list, preferably soon, before insect season. First and foremost, make sure you consult your veterinarian. Variations in a vaccination plan may be due to your horses age and exposure to other horses, and travel plans. According to the American Association of Equine Practitioners, the following *core disease vaccinations are those we ALL should make sure our horses are protected from. These recommendations are if the horse has been previously vaccinated, and is greater than one year of age.
- Tetanus - Annual vaccination with tetanus toxoid, with a booster if a penetrating (puncture) injury occurs
- Rabies - Annual vaccination
- Encephalomyelitis (Eastern and Western) - EEE and WEE should be vaccinated for each spring and fall. With the mild winters we generally have (especially this year) this is critical to protection from the virus carried often by mosquitos
- West Nile Virus - Similar to Encephalomyelitis, West Nile vaccination is also needed each spring and fall
*Core disease vaccines are named such because they protect against diseases that are endemic to a region, virulent or highly contagious, pose a risk of severe or fatal disease, have potential public health significance, and/or are required by law. Core vaccines have clearly demonstrable efficacy and safety, with a high enough level of patient benefit and low enough level of risk to justify their use in all equids.
The next vaccines are risk based, meaning that they are selected based on assessment of risk performed by, or in consultation with, a licensed veterinarian. Needs vary between individuals, populations, and/or geographic regions.
- ·Equine Herpesvirus (EHV)
- Equine Influenza
- Equine Viral Areteritis (EVA)
- Potomac Horse Fever
- Strangles
- Anthrax
- Botulism
- Leptospirosis
- Rotavirus
There are many factors which influence the right vaccination protocol for your horse. Stages of life, such as age, reproductive status, activity and exposure to other horses are all considerations. Always make sure to consult your veterinarian for the best vaccination protocol to ensure the well-being of your horse.

Buttercup Weed Management
Buttercup is a short-lived perennial weed that behaves more like a winter annual. It begins to germinate in the fall and grows into the spring when the weather warms up. It has characteristic shiny, bright yellow flowers with five petals. This weed thrives in pastures where there is little competition, such as overgrazed areas or bare patches.
All parts of the plant are toxic to livestock and can cause blistering in the mouth and internal parts of the digestive tract, diarrhea, colic, and even death in extreme cases. However, buttercup is bitter and most horses will refuse to eat it as long as other forage options are available. The toxin that causes these issues will not be active when the buttercup is dried, so it is not a concern in hay.
Since buttercup starts growth in the fall, it is important to have a thick stand of grass that will prevent the new seedlings from taking root. Proper fertilization and grazing management in the fall will help encourage this thick stand. Avoid overgrazing throughout the winter to prevent creating an environment that is favorable to buttercup growth.
When buttercups are present, mowing in the spring can help reduce flowers and therefore seed development. But mowing alone will not eliminate the plant and the problems it poses.
Chemical control is a very effective strategy, but it is important to utilize this method early. Once it flowers, the plant is too mature for herbicides to have effective control. The ideal time to apply herbicides is late February through early March while the weeds are still small. 2,4-D is an effective herbicide that provides good control when applied early. Other effective herbicide options include aminopyralids (eg. GrazonNext), 2,4-D + dicamba (eg. WeedMaster), triclopyr (eg. Crossbow), or metsulfuron (eg. Cimmaron). Picking the right product can depend on other weeds you need to control at the same time.
If your pasture had issues with buttercup last year, you can count on them being back again this year. Start scouting early and be prepared to utilize control methods. If infestations have been heavy in the past, do not expect this problem to go away after one herbicide application. It can take several years of timely chemical control to get the buttercup under control. Always encourage a thick healthy stand of grass to help reduce weed pressure.

Breeding Considerations
1. Does my mare possess the desired traits that should be passed on to her offspring?
Is the mare conformationally correct and does she have a good attitude and disposition? These are certainly hereditary traits she will pass on, and those traits should also be considered in the stallion you select to breed her to!
2. Why am I breeding my mare?
Owning a horse is a long-term commitment, and having a foal requires even more commitment. We all love cute foals, but with them comes increased care and cost. A pregnant mare requires increased nutrition, particularly the last three months of her pregnancy, and while she is nursing her foal. Are you prepared to work with your foal to ensure they are handled and cared for? Do you have a plan for training them for their future intended purpose?
3. Is my mare healthy enough to conceive a foal and carry it safely to term?
A mare should be in prime condition before breeding time arrives. Mares should be a body condition score between 5 and 6, carrying a little extra condition but not too heavy. Is she current on her vaccination on a sound parasite management program? Has she had a recent dental exam and are her hooves in good shape? Are there any underlying signs of disease such as Cushings Disease or thyroid imbalance?
2. Has my mare undergone a reproductive exam by a veterinarian?
Not all mares are created equal. A breeding soundness exam will ensure all reproductive parts are in good working order. A mare with poor perineal conformation (the vulvar lips, vaginal area, and cervix) will be more susceptible to infections caused by contamination from external particles in the uterus. A uterine culture can rule out any infections that may need treatment pre-breeding and stitching the vulvar lips, called a Caslicks, can prevent further infections post-breeding and stitches are removed pre-foaling. Ultrasound exam of the uterus can also determine the health of the uterus.
3. Do I have a plan to monitor when my mare needs to be bred?
As with people, knowing the prime conception window is important. Mares cycle seasonally when days or longer, or when they are exposed to longer periods of artificial light. After they begin to cycle, mares come into heat about every 21 days and their heat period lasts five to seven days, with ovulation happening the last 24-48 hours of the heat period. Breeding should occur as close as possible to ovulation, so knowing exactly how a mare's heat cycle occurs plays an important in planning when she needs to be bred. On many breeding operations, an intact male horse known as a teaser is a valuable tool to help predict when the mare is closest to ovulation.
4. Will I breed my mare through artificial insemination (AI) or live cover?
Either method is a viable means of ensuring pregnancy, unless you are seeking to have a registered Thoroughbred as they accept live cover only. Both methods take planning however, whether it be to arrange transportation to a stallion farm for live cover based on their requirements, or purchasing semen for AI and working with a veterinarian for insemination at the proper time.
There is nothing more exciting that witnessing a foaling, especially when a healthy
foal arrives from a healthy mare. Considering the above factors will help you achieve success!

Forage Alternatives
As we enter
the dog days of winter, it is not uncommon for our hay stores to run low. For
some, this poses a challenge if there is not a sufficient supply of quality hay
for sale nearby. One might have to resort to a forage alternative, to make it
through to spring when the grass again becomes prevalent.
There are a variety of forage alternatives available, and the best option will
depend on a variety of issues, including the body condition of the horse, his/her
physiological state, the quality of forage alternatives accessible in the area
and, of course, cost. These forage replacements can help stretch hay supplies
through the winter months, or they can even help in summer months when grazing
is limited during times of severe drought. Some forage options available
commercially are chopped hay, hay cubes/pellets, beet pulp, haylage, etc.
Chopped hay also called “chaff,” is becoming more common in equine diets. It can provide a mix of digestible and indigestible fiber to maintain proper function of the digestive tract. Chaff is also sometimes mixed with molasses to enhance palatability and sometimes has added nutrients to provide for a more complete ration.
Forage
cubes/pellets simply
are hay that has been chopped coarsely (or finely) and formed (with the
addition of a binder) into scoopable, baggable pieces. They’re more convenient
to move around than baled hay, and they have the advantage of a guaranteed
nutritional content that is posted on the bag so you know exactly what you’re
delivering in terms of essential nutrients. Hay cubes and pellets come in a
variety of sizes and textures, from soft and crumbly to quite hard, and they
can be all-alfalfa hay, all-grass hay, a mixture of the two, or even hay mixed
with other products.
Beet pulp is one of the most commonly fed forage
alternatives. The digestible energy and fiber content generally falls between that
of grains and hays, the protein content is similar to a decent quality grass
hay, and it is relatively high in calcium. You can feed it to meet up to 50% of
the forage content of the diet, ideally limiting it to 10 pounds, on a dry
weight basis per day. Beet
pulp is usually fed soaked to mitigate any issues associated with choke.
Soybean hulls are high in fiber and are one of the most digestible hull
types. They can be used to replace about 50% of the forage. They are rather
lightweight and tend to blow away if not either pelleted or mixed with a
binder, such as molasses. The biggest drawback to feeding hulls is they are
usually dusty, have very low vitamin content and result in less overall chew
time which can minimize the amount of bicarbonate produced that acts as a
temporary stomach buffer.
Haylage is more commonly fed in European
countries, although in recent years it has gained some popularity in the United
States. Haylage is a form of chopped hay that is harvested and baled with a
moisture content higher than traditional hay. It is sealed in plastic, allowing
for some fermentation before being fed.
Advantages
of haylage are that it is relatively dust-free because of its higher moisture
content, and it is also slightly higher in nutritive value. The biggest concern
with haylage is the development of mold and mycotoxins if it is not stored
properly. It will mold quickly–usually within four to five days–once the
package is opened and the forage is exposed to air.
Keep in mind that in order to maintain proper digestive health, roughages/forages must make up a minimum of 50% of a horse’s diet on a dry weight basis, or about 1 pound per 100 pounds of body weight. Also, make any changes to the horse’s diet gradually. Feed horses on the lower-fiber alternatives more frequently (four times a day) to satisfy the basic grazing requirements and to reduce boredom or less than ideal behaviors.

Wet Winter Skin Infections: "Scratches & Rain Rot"
It's been a warm, wet, winter this year in most of North Carolina. These are the kind of winters that cause mud in the pastures and on the trails. Along with that mud comes fungal/bacterial infections to watch out for in your horse.
Scratches
"Scratches," a common skin condition in horses, can affect the heel, the back of the pastern, the fetlock, and occasionally the cannon bone. Veterinarians may refer to it as pastern dermatitis or pastern folliculitis. It is also known as "mud fever", "dew poisoning", "greasy heel" or "cracked heels". It basically looks like a bunch of thick scabs all over your horses lower leg. Any horse can get scratches but it seems to be more prevalent in white legged horses and horses with feathers such as draft breads.
To treat scratches, remember "Don't scratch the scratches!" Picking the scabs will only make it spread. Clip hair around the affected area and wash with antibacterial shampoo (chlorhexidine, betadine, or benzoyl peroxide) and let sit for 10 minutes before rinsing. Do this once a day for about a week and then reduce to 2-3 times per week until resolved. In severe cases a veterinarian may recommend antibiotic, anti-fungal, or steroid ointments. Prevention is the best method of managing scratches. Keeping a dry clean environment for your horse and making sure legs are clean and dry after riding/turn-out.
"Rain rot", also known as rain scald or dermatophilosis, is a skin infection caused by a bacteria. Though rain is one risk factor, any form of moisture such as sweating under a blanket can cause the inflammatory infection resulting in lesions along your horse's skin. These lesions cause small patches of raised bumps which are scabs containing clusters of your horse's hair.
While most often found on the horse's top-line, rain rot can be found on numerous areas of the horse's body, including their rump, face, and legs. Unlike many other skin conditions, areas with rain rot do not typically itch but can be painful and cause your horse to become sensitive to touch. All horses can get rain rot, however horses with lighter coat colors as well as horses with compromised or poorly developed immune systems (such as young or older horses) have been found to be at higher risk.

Coggins: What is it and why do it? Horses in NC have Tested Positive Recently
- Use disposable needles and syringes, one per horse, when administering vaccines and medications.
- Sterilize dental tools and other instruments before using them on another horse.
- Test all horses for EIA at least annually.
- Test horses at the time of purchase examination.
- Stable owners, horse show and event managers should require and verify current negative Coggins certificates for all horses entering the premises.
- New horses should be quarantined for 45 days and observed for any signs of illness, including elevated temperatures, before introducing them to the herd. They should be retested if exposure to EIA is suspected at a 45-day interval.
- All stable areas should be kept clean, dry and waste-free. Good pasture management techniques should also be practiced. Remove manure and provide adequate drainage to discourage breeding sites for pests.
- Horses at greater risk, such as those in frequent contact with outside horses or who live or travel in geographic regions known for EIA outbreaks, should be tested more frequently, every 4 – 6 months.
