Goat Health

As the owner, it is ultimately your responsibility to provide a healthy environment so that your goat may flourish and grow. A keen understanding of good husbandry practices, basic infectious disease prevention, diseases and conditions specific to your goat and your farm are critical to the success of your project. This document is only meant to be a starting point for your farm health plan. You should also establish a relationship with a veterinarian to assist with a protocol specific to your farm.

FDA Restrictions

Off-Label use of antibiotics, dewormers and other treatments is strictly prohibited in food animals. These rules are set in place to protect the consumer and our food supply. Be sure to check all medication labels and comply with labeled use, dose and withdrawal times. Very few treatments are FDA approved for goats. You are directly liable for inappropriate or illegal use of non-approved medications in these animals. Off-label use of some medications may be permitted under direct supervision of a veterinarian. Your veterinarian can help you with proper use of medications in your goat.

Vaccinations

Limited vaccines are available for sheep and goats. Ideally, animals should be vaccinated by the breeder and prior to purchase or moving. It is critical that you discuss specific risks and needs with your veterinarian to customize a vaccination protocol for your farm.

At a minimum, all goats should be vaccinated with:

CD&T Vaccine: This vaccine includes protection for overeating disease (Clostridium perfringens Type C & D) and tetanus (Clostridium tetani). Kids should receive an initial dose at 1-2 months of age. Booster one month later. Booster adults annually.

Rabies Vaccine: Vaccination against rabies virus is recommended in project animals due to the potential zoonotic risk of becoming exposed or infected. Rabies vaccine must be administered by a licensed veterinarian.

Parasite Management

Parasitism is the number one herd health problem in goats. Resistance of parasites to dewormers is also extremely common.

Identify the culprits

• Keep simple records that include identification, body condition score and FAMACHA score.
• Approximately 10% of the animals carry 90% of the parasites in any given herd.
• These animals become a “typhoid Mary” that will continue to incubate and spread large numbers of worms to the remainder of the herd.
• Animals that are repeatedly sick from parasites should be removed from the herd.

Grazing & Pasture Management for Parasite Control

Grazing With Other Species
Goats do not share parasites with horses or cows. Cross grazing or rotating pastures with cows and horses is beneficial and will help dilute the parasite load on the pasture.

Goats will share parasites with sheep, llamas and alpacas. Therefore, cross-grazing or rotating pastures with these species should be avoided.

Grazing Time
Delay grazing until the afternoon. Haemonchus contortus (barber’s pole worm) larvae hatch during warm summer nights and follow the dew drops to the tips of the grass. Goats that graze early in the morning on the damp grass will ingest more parasite larvae. By midday, when the grass dries, the parasite larvae will recede to the ground. Therefore, delay grazing until later in the day when the grass has dried.

Where to Graze
Graze brush, avoid lush pasture. Haemonchus larvae thrive in the lush green pasture. Therefore, in the hot summer months, goats should graze brushy areas.

Stocking Rate
Pastures that are overgrazed will harbor more parasites. Avoid overgrazing. Reducing the overall herd size or increasing the available pasture may be necessary.

Rotate Pasture
Pastures should be rested for at least 6 months. Shorter intervals will result in worsening parasites.

Deworming

Determine if Goat Should Be Dewormed
-Use the FAMACHA score card to determine whether goats should be dewormed.
-Deworm all that score 4 or 5.
-Scores should be checked every 2 weeks during hot, humid summer weather.

Fecal Exams
Fecal exams are recommended to identify whether treatment for coccidia is needed.

Fecal Egg Reduction Counts
-Help determine whether parasite resistance is a problem on your farm.
-Requires a fecal exam prior to deworming and a repeat fecal exam at a specified day after deworming.

Deworming
Weigh animals if possible to ensure correct dosing. Use the updated dosages provided. Animals should be held off of feed for at least 12 hours prior to dosing with an oral deworming product.

Copper Boluses
Copper has been shown to reduce parasite levels in the animal. Boluses should be given once a year. Copper levels should be monitored as toxic levels may occur with long term and repeated usage.

Other Common Problems in Goats

Our veterinarians frequently diagnose the following diseases in goats:

Pediculosis (Lice)
There are two types of lice commonly found on goats: chewing lice and blood sucking lice. Both will cause poor growth. However, each type of lice requires a different treatment. Chewing lice may be treated with topical delousing dusts. Sucking lice require a systemic medication.

Coccidiosis
This disease is caused by an intestinal parasite that is not treated with typical dewormers. Affected animals will have poor growth and diarrhea. Severe cases result in death. Young animals from 2-6 months of age are most susceptible to this disease. We recommend feeding a medicated ration containing a coccidiostat to susceptible animals. In some cases, a stronger prescription treatment may be required to treat coccidia.

Urinary Calculi
Urinary calculi are extremely common in pet goats and project goats due to feeding concentrate diets. Concentrate diets will cause changes in urine pH which promotes formation of urinary stones. Many goats will pass stones through the urethra without further trouble. However, males are extremely prone to urinary blockage due to urinary calculi or stones. This can result in kidney failure and death. We discourage feeding any concentrate feeds for this reason. However, if you are feeding a concentrate, ensure that it contains ammonium chloride. Monitor your males goats for normal urine passage. If you note straining to urinate you should contact your veterinarian immediately. Our veterinarians have treated goats with several techniques including amputation of the urethral process, perineal urethrostomy and tube cystotomy. The best treatment for urinary stones is prevention!
