Blackleg in Sheep

Blackleg
Blackleg (c.chauvoie) and ,malignant edema (c.septicum) are other clostridial diseases that more frequently occur in cattle but can also affect sheep. Tetanus (c.tetani) is yet another clostridial disease that is always a threat during tail docking or when open wounds are present.

Excellent vaccines are available for these diseases if they are known to cause problems for sheep in your location. Clustridial vaccines with up to 7 or 8 antigens are available for use in sheep and can be used on the same schedule as described for enterotoxaemia.

Livestock Pinkeye (Keratoconjunctivitis)

Pinkeye is an inflammation of the surface of the eye and of the inner surfaces of the surrounding conjunctival tissue. This often produces redness in the tissue, hence the name.
Pinkeye may affect one or both eyes. Redness and swelling of the tissue surrounding the eye and excessive tears are noticeable side effects. Pinkeye is often caused by a Chlamydial agent, but may be caused by bacteria or mycoplasma organisms as well.  If left untreated, it may damage the cornea by ulceration; this can lead to permanent blindness. Pinkeye can spread by direct contact or via flies. Reported outbreaks have affected over 90% of the flock.  
Treatment: Tetracycline antibiotic ointment is placed in the eye everyday for several days. The Chlamydial agent in pinkeye is especially sensitive to this drug. Sever outbreaks may require the subconjunctival injection of antibiotics by a veterinarian to provide more prolonged treatment. If the lower lid rolls in directly onto the eye, it must be corrected by a veterinarian before causing permanent damage to the cornea.
Separate infected animals, reduce dust and control flies to reduce new cases.

Health Benefits of Eating Lamb

Lamb is a good source of high quality protein with 60.3% of the daily protein requirement. The meat also provides Selenium, a mineral whose deficiency is associated with asthma attacks. Lamb is rich in Iron, an integral component of hemoglobin and aids formation of red blood cells. The Iron form in lamb meet is easily absorbed by the body. Zinc is found in lamb meat as well and promotes a healthy immune system. Vitamin B12 is present in moderate levels and help to prevent a dangerous molecule called homo cysteine from harming the body. Vitamin B3 is known to protect against Alzheimer's disease, promote healthy skin and keeps age related cognitive decline at bay. More over, it retards the risk of developing  osteoarthritis by as much as half. Lamb is an excellent alternate meat for health conscience people and is a great source for "good fat" with lower saturated fat than most other meats.

Karras Farm wishes you all a very Merry Christmas.

God bless

Dairy Sheep - Boils or Abscess

A boil or abscess is a localized accumulation of infectious tissue and fluid in response to a bacterial infection. The most common infection in sheep is caseous lymphadenitis (CL), which localizes in the lymph nodes.

A variety of bacteria may cause an abscess, but the cause (CL) is corynebacterium pseudotuberculosis. It often causes multiple abscesses in the lymph nodes around the head, neck and shoulders. It may also affect internal organs, such as the liver, kidneys and lungs. It may result in chronic weight loss or death in extreme cases. Caseous lymphadenitis can spread between animals. When an external boil ruptures, the bacteria are dispersed. This can be a particular concern at shearing time.  It may take several months for lesions to develop in newly infected animals.  Individual abscesses can be lanced and drained or surgically removed. When Lancing or removing a lesion, you must exercise great caution to not further spread organisms to other sheep.  There may still be internal abscesses that cannot be seen or removed. Antibiotics are generally of little benefit as they struggle to penetrate the thick capsule of tissue that forms around the infected area.
Maintain fences, feeders and corrals to minimize injuries. Shear the youngest sheep first and take great care to not rupture any abscesses. A vaccine is available but it must be administered when lambs are very young to promote immunity prior to exposure.

Sheep Feed and Digestion

To understand how to properly feed your flock, you need to know a bit about ruminant digestion. Ruminants have a four chambered stomach as opposed to a single stomach like humans, dogs, horses, pigs and many other animals. When sheep eat grass or hay, the food slips down the esophagus into the largest chamber , a fermentation and storage organ called the Rumen. Sheep don't do much chewing as they forage, that activity comes later. When the sheep finds a quiet spot to rest and regurgitate the under-masticated vegetable matter, it will then do some real chewing or ruminating, before again swallowing its "cud" for final digestion. Even with all this rumination, the cellulose in fibrous plant feed is difficult to digest. Fortunately, ruminants have billions of helpful protozoa and bacteria residing in their Rumen that flourish on high fiber diets. These microbes produce protein as a by-product of the fermentation process, another perk for the sheep. Further digestions occurs in the Abomasun or true stomach, which secrets acids and enzymes similar to the human stomach. The basic components of a healthy sheep diet include water, forage, grain, vitamins and minerals.


Have a blessed Holiday ~ Happy Thanksgiving to you and your family

East Friesian Sheep - Nasal Bots

Nasal Bots are the adult stage of the female fly. They lay tiny eggs on the nose of sheep, then the larvae crawl up the nose and into the sinuses where they mature into large larvae. Eight to ten months later the bots come out of the nose, drop to the ground and develop into flies. While in the sinus, the larvae may cause severe irritation. Ivermectin products are most effective against the larvae stage but sheep may be repeatedly affected as new larvae migrate to the sinuses.

Liver Fluke in East Friesian Dairy Sheep

The adult stage of this parasite lives in the bile ducts in the liver of sheep.
A very small number can pose a detrimental effect on the host. Larvae hatch eggs passed in the feces, but they must be ingested by a snail to move to the next stage of development. Flukes are usually found in damp meadows or wetlands where snails are present.
Prevention can be directed at drying up wetlands or fencing sheep away from them. Two available medications, Clorsulon and Albendazole are effective if given after the first of January when the larvae have developed into adults in the liver. After 2-4 years of use the number of eggs and larvae on the pasture should be greatly reduced and pose little threat. Continued use of these medications is necessary to prevent resurgence.
Have a wonderful weekend~
