Biosecurity for Cabin Fever Candidates

In cooler seasons, such as winter, often horse owners travel to warmer climates with their Equine companions. Many important considerations should be made prior to traveling. One of the most important is biosecurity. To better understand biosecurity, it is important to understand the meaning: “Bio” means life, “security” means protection. As horse owners it is important to prevent horses from contagious diseases. These diseases can be transmitted from place to place by other horses, people, insects, equipment, and trailers. Good biosecurity is an excellent habit to make at home and take on the road.

Prepare

Talk to your veterinarian about your travel plans and considerations for a vaccination protocol well in advance of travel, giving your horse’s immune system time to build up protection. Many veterinarians will suggest a herd health program appropriate to your specific lifestyle needs, including travel and awareness of geographical diseases to be aware of. If your horse will be transitioning to different forage or feed, it is helpful to pack enough “transition forage and feed” to last the duration of the trip and enough to transition once you arrive at your destination. Forages vary between geographical regions, it may also be helpful to get a forage analysis ahead of time to be prepared with your transition feeding program.

Transportation

If possible transport your horses in your own trailer. You will be more aware of what kind of exposures exist in your own trailer. If you must transport in a shared trailer or with other horses, be sure to clean and disinfect prior to loading your horse. It may also be helpful to request proof of health records of horses traveling with your own or a reputable transporter who requires proof of vaccination and health certificates for all horses being transported. Some horses are more stressed by travel, be sure to pack plenty transition forage and feed for the duration of the trip and for transition. Hydration and enough periodic rest is beneficial. Once you arrive at your destination, inspect the location for hazards. Do not unload your horse until you are comfortable with the biosecurity and safety of the location. Some things to consider: Are other horses healthy? Have there been any recent health issues on the property or nearby? Are there any insects or pest issued to control prior to your horse unloading? Clean and sanitize all buckets, ensure water sources are in clean and working order, fencing is safe and appropriate and hand washing before handling your horse.

Prevention

If a horse is sick, isolation and a stall notice or special collar will help others know not to handle the sick animal to avoid disease transmission. Basic hand washing is important between handling more than one horse even if the horses are healthy. It is best to have equipment for each individual horse, however if some equipment must be shared it is important to wash and sanitize between horses to prevent disease transmission. Clean footwear is important. After walking in pastures, alleyways, and yards it is important to wash the bottoms of your footwear prior to getting into your vehicle, trailer or stalls/pastures when traveling from farm to farm or any animal environment. Keep weeds and grass cut to prevent insects and pests. Prevent and remove any standing water from puddles, buckets, or old equipment. Use of equine safe fly control program will help control fly populations. Store horse feed and supplements in a cool, dry, well lit, rodent proof, limited access area. Inspect water access daily, clean and empty any water buckets or troughs at least once weekly.

Horses, Heat and Humidity

Water into bucketSummer is in full swing, including the heat and humidity. Horses, similar to humans, may have a difficult time coping and cooling off with the combination of heat and humidity. The added challenge of cooling off partially results from the inability of the sweat to evaporate in humid weather. The combination of sweat and humid weather acts like an insulation, making horses even hotter. Some horses have diagnosed trouble sweating (anhidrosis) during hot and humid weather, which adds other challenge to cool off. Consult Veterinary support if your horse has trouble sweating.

Some ways to help you and your horse cope with hot humid weather is to calculate the temperature-humidity index (THI). Add the air temperature (in degrees Fahrenheit) to the humidity percentage. For example, if it is 80 degrees Fahrenheit and the humidity is 60%, the THI is 140. When the THI reaches 150, horses will have difficulty cooling off, at 180 working a horse can be unsafe to the horse’s health and you should actively help the horse cool off.

Another supportive tool is to take your horse’s temperature. Normal is between 99.5 and 100.5 degrees Fahrenheit at resting, and can range between 103 to 104 degrees during exercise. When a horse’s temperature reaches 105 this is dangerous and the risk of overheating or health damage can occur. Above 105 degrees horses are likely to suffer heatstroke and require immediate Veterinary attention.

Helpful ways to keep horses cool in hot humid weather:

1. Clean and cool water available at all times

Horses prefer fresh, cool water in sufficient amounts when it is hot and humid. Keeping clean and cool water in deep buckets in the shade will help keep water cool. In addition to the automatic waterers (if available) additional deep buckets may be required to allow horses to gulp water versus sip smaller amounts. I often will consume a substantial amount of cool water in one sitting in a light colored container when it is hot and humid.

2. Provide appropriate feed for the horse’s activity

Feeding excess hay in hot humid weather can contribute to added body heat from the digestive process. Feeding smaller amounts more frequently or use of a slow feeding hay bag may be beneficial. Feed a quality balanced feed that is designed for the exercise requirements of the individual horse. If I am a daily jogger, my nutrient requirements vary significantly from a marathon runner in training.

3. Consider individual fitness

Physical fitness and environments vary between individual horses. Research has shown horses well-conditioned and of optimal physical fitness tend to cope with hot humid weather more easily than those who are out of shape. Horses residing in climates with extreme heat and humidity tend to cope better than horses traveling and adjusting to different climates. Although the horses may cope better if they are acclimated to the heat and humidity, it is still important to observe safe exercise and offer healthy ways to help horses keep cool.

The Skin Health of Your Horse

Before diving too deep into skin issues, it is important to understand skin components. The skin is the body’s largest organ, representing 12-24% of the animal’s body weight, depending upon species and age. The skin is composed of five zones:

  • Dermis
    • Supports and nourishes the epidermis. There are cells, fibers and nerve plexuses present in the dermis.
  • Basement Membrane Zone
    • Primary function is to attach and act as a barrier to the epidermis and dermis. Several factors including autoimmune conditions can impact the health of the basement membrane zone.
  • Epidermis
    • Often hair covered and the first barrier of defense. Also composed of multiple layers. The overall health of these layers are influenced by nutrition, hormones, tissue factors, immune cells and genetics.
  • Appendageal System
    • Contains structures that grow with the epidermis such as hair follicles, sebaceous and sweat glands. Hair growth is impacted by many factors including nutrition, hormones and sunlight.
  • Subcutaneous Muscles & Fat
    • Has many functions such as insulation, shock absorber, and a reservoir for hydration. (Merck, 2015)

Skin issues generally fall under five categories:

  1. Traumatic skin issue or skin wounds/lacerations often from environmental hazards such as fencing, barn structure, or other objects.
  2. Granulomatous skin issue or “proud flesh can occur when a wound goes untreated or unnoticed following injury.
  3. Nodular skin issue or skin associated with seasonal conditions or allergic dermatitis from insects such flies and ticks.
  4. Pruritic and alopecic skin issue or contact dermatitis often from plants, irritating chemicals or “Sweet Itch” associated with gnat bites. Other Ectoparasites such as Lice and Mange are contributing factors of this type of skin issue.
  5. Nonpruritic and alopecic skin issue or “Rain Scald”/“Rain Rot” from prolonged exposure to environmental conditions is one major factor contributing to this type of skin issue.

Because of these various potential skin issues, it is important to include a quality care, management and grooming routine for your horse. Brushes and equipment should be cleaned between horses. If a contagious skin disease is suspected, designate a set of grooming supplies to be used only on the horse with an issue.

Skin health is affected by many components of nutrition. Proper hydration and access to a quality water source is the cornerstone of skin health. A quality balanced diet rounds out an optimal skin health plan. Diets balanced in essential amino acids, Omega-3 and Omega-6, and vitamins and minerals.

A proper farm insect management program starts with cleanliness and prevention. Keeping manure removed or far from horse barn, stalls or paddocks is essential. In a barn environment use fans to help deter flying insects from horse stalls or confined areas. Remove standing water or keep horses further from standing water sources to help reduce insect experiences. During peak insect seasons use of fly bonnets, fly sheets or safe insect repellents. If desired, a feed through fly control product can be incorporated into a full insect control program.

Bathing or “cold hosing” the horse’s skin can help with discomfort of skin issues. It is appropriate for horses in exercise to be “bathed” or hosed off after exercise. It is important to scrape/wipe off excess water and properly cool out any horse to avoid additional complications. Care should be taken to not “over bathe” or use harsh shampoo or chemicals on the horses’ skin.

Please consult your Veterinarian before administering any medicated or chemical treatments or for additional information on skin diseases and treatments.
