Ovine Progressive Pneumonia

Ovine Progressive Pneumonia (OPP) is caused by a slow growing virus that infects lambs and manifests itself as a disease after the lamb has reached two years of age. It primarily affects the lungs and udder, but may also involve other tissues.

OPP causes chronic weight loss despite a good appetite; labored breathing; and a well formed udder that produces little to no milk. Opp can spread from older animals to lambs through the ewes’ milk.

Some producers have established OPP-free flocks, but this can be very difficult and expensive to accomplish. Don’t confine young sheep in close quarters with infected adult animals. Cull affected animals early in the course of the disease. A blood test can be used to determine if a sheep is infected, but may not be 100% reliable. A Necropsy is the only way to determine with certainty if an animal is infected with OPP. There is no known effective treatment for OPP and the disease slowly leads to death.

At Karras Farm, all our East Friesian Dairy Sheep are OPP- free flocks. We strive to produce the healthiest dairy sheep in the world.

Thank you,

How To Detect A Sick Sheep

How to detect a sick sheep:

Detecting a sick animal quickly can prevent loss of life and the potential spread of disease to the flock.
You must become familiar with normal behavior of your sheep. You must also have quick and easy ways of catching sheep to access them if needed. Areas such as a feed corral work well. 

Signs of abnormality are loss of appetite or not coming to eat as usual, not ruminating and standing apart from the group when at rest. Be very concerned if a sheep is laying down most of the time when other sheep are not. Any weakness or staggering, unusual labored or fast breathing, change in bowel movement, wool discoloration or slipping, hanging their head over the water source or a temperature over 104 degrees can all be possible indications of illness.

The normal temperature of sheep ranges from 100.9 to 103 degrees (average 102.3 degrees). A veterinary rectal thermometer has a ring or hole at the outer end to tie a string for easy removal.

If it is necessary to catch a urine sample for use with the pregnancy toxemia (ketosis) strips or glucose strips for Enterotoxaemia, try holding the sheep nostrils closed for a moment. This "stress" sometimes triggers urination.

Areas where sheep are more likely to transmit germs:

1.      Water or feed contaminated by feces from sheep or other animals can transmit intestinal diseases and parasites.
2.      Respiratory disease may be spread by nasal discharge or feeding containers.
3.      Dirty uncrotched wool on a ewe can infect the lamb.
4.      Manure accumulated in a lambing shed or around a feeding trough can intensify exposure to disease germs and Coccidiosis, serve as breeding grounds for flies and other vermin. Another side affect can be the production of ammonia fumes which can inhibit respiratory function.
5.      Wet, muddy places can cause hoof disease in sheep
6.      Feeding on bare ground should be avoided and can contribute to parasite exposure and disease.
7.      Venereal transmission of disease at breeding time.
8.      Dirty syringes and needles can cause injection site infections.
9.      Insects, birds, snails, dogs, cats and other hosts can be carriers of parasites and disease.
10.  Newly acquired sheep can be carriers of many serious diseases such as Brucellosis, Chlamydia, OPP, Foot Rot etc.
At Karris Farm we maintain a healthy and sanitary surrounding. Our East Friesian sheep are adequately fed a well balanced diet on a normal schedule which aids in the prevention of disease. We also deworm our east Friesian Dairy Sheep regularly preventing parasite build up which can weaken the sheep and leave the more susceptible to disease. Sound management dictates that sheep should be vaccinated against all ailments and diseases prevalent in your area.

We wish all our friends, customer and sheep lovers a wonderful summer!

Dairy Sheep - Early Lambing or Late Lambing?

There are some advantages / disadvantages for both early and late lambing so we thought we would share some of our experiences on both.

Early Lambing:

  1. There are fewer parasites on the grass pasture due to the colder temperatures.
  2. Ewe lambs born early are more apt to breed as lambs.
  3. The earlier they are born the sooner you're able to place lambs at their new homes.
  4. Lambs will be ready to graze the fresh spring grass.
  5. Very few fly problems in the winter. 
Late Lambing:

  1. Ewe will require sheering prior to lambing which can be stressful.
  2. Lambs tolerate the cool weather better. Typically lambs born in a hot environment will not develop as quickly.
  3. Less grain is required  for late lambing.
  4. Ewe and Ram lambs will not reach breeding maturity until the following spring.

At Karras Farm, we have found that lambing in February has the best all around benefits. By May the lambs are at their new homes and we prevent some of the negative side effects that late lambing can promote. We believe that early maturity is key to prolific lambs.

Please stay in touch and feel free to leave comments with your experiences.

Sincerely,

Sheep Guardian Dogs

Coyotes and stray dogs are increasing in numbers and have become an extreme danger to lambs. Stray dogs can cause more trouble than Coyotes. One or two stray dogs have the ability to destroy and maim dozens of sheep in a single night. Coyotes primarily make one kill to feed while dogs find it to be more of a sporting event and thrill of the kill. Killings usually occur at night or very early morning. It's important to employ a sheep guard dog for protection of the herd. Guard dogs are on duty 24/7 and they are most alert during times of greatest danger.

At Karras Farm we breed Anatolian Shepherds to protect our East Friesian dairy sheep. The Anatolian Shepherd is known for excellent sheep herd protection and they integrate well with new lambs during birthing season. Guard dogs are not family pets; they are working dogs and should be integrated with the herd at all times. Karras Farm offers a limited number of Anatolian Shepherd puppies to our existing customers. If you have an interest in learning more about guard dogs or future availability of our pups please feel free to contact us.

Thank you and best wishes with keeping your animals safe from predators.

Sincerely,

Life Expectancy of Sheep

The life expectancy of sheep is similar to a large dog breed of about ten to twelve years. Some sheep breeds are known to have a longer life cycle such as the Merino. According to the Guinness Book of World Records, the oldest sheep lived to be 23yrs. She was a Merino however; the length of a sheeps productive cycle is much shorter. A ewes offspring production is highest between three and six years of age and usually starts to decline after age seven. As a result, most ewes are removed from our flock prior to reaching their natural life expectancy. It is necessary to remove the older ewes in order to make room for the younger animals. As we mature our genetic line of sheep we must provide an adequate environment for the younger sheep to thrive. In harder environments, where forage is sparse, ewes are usually culled at an even younger age due to tooth ware and break down.  It can become difficult for sheep in these conditions to maintain proper body condition and consume enough forage to feed their lambs. It is possible for a ewe to be productive past ten years of age and stay healthy but this is typically the exception to a natural sheep life cycle.

Hope all your lambs are happy and healthy!

Retained Afterbirth

In most cases the afterbirth comes out normally within a few hours after the lamb is born, depending somewhat on the activity of the ewe. Don't ever try to pull out the afterbirth. You may cut it inside the ewe or cause her to strain and prolase among other potential injuries. You can allow some time to pass without worrying about the afterbirth. If six hours have passed and the afterbirth is still retained, we recommend Penicillin G twice daily (every 12hrs) for five days and a good vaginal flush. This should be followed by Oxytocin in the muscle asap. This will help the ewe sterilize the area while the Oxytocin aids in helping the ewe push out any remaining afterbirth.

Make it a super day!
