Diseases of Sheep:

Pneumonia:

It is a disease of the lungs, its symptoms are fever, cough, discharge of flows through the nose, difficulty breathing.

This disease is caused by poor nutrition; Parasites, mainly pulmonary worms; Use of damp and poorly ventilated facilities.

Diarrhea:

Lambs should take the first milk (colostrum) to develop resistance to diarrhea, they should take it within two hours after sunrise.

Diarrhea is a disease that ravages newborn lambs, is caused by bacteria that enter through the mouth and poor sanitary conditions.

To cure diarrhea you should compensate for the loss of fluids, provide antibiotics or sulfa and clean the facilities periodically.

Colibacillosis:

It is an infectious disease caused by bacteria that is located in the intestines, it is also known as white diarrhea; Is very common in newborns who have not received colostrum.

Internal parasites:

Internal parasites or worms are common in sheep. When the ewe eats grass, it eats larvae of worms that once adults in the body of the sheep reproduce in the form of eggs. The sheep on defecation deposits these parasites again in the form of eggs, producing a cycle of contamination.

What to do to break the cycle?

  • Do not herd sheep near dirty water.
  • Keep corrals and accommodation clean.
  • Keep sick animals separated from healthy animals and remove their excreta.
  • Avoid contamination of food and water with excrement.
  • De-spraying your animals periodically (at least every 6 months).

External parasites:

External parasites live on the hair and skin of the sheep, suck the blood, causing a delay in growth and transmit diseases.

To prevent them, it is necessary to inspect their animals frequently, if they are infested to separate them from the healthy ones and to cure them. Spray, sprinkle or regularly bathe the animals as a precaution.

Aphthous fever:

Foot-and-mouth disease is caused by a virus, which causes death in animals. The virus penetrates through the mouth, through the consumption of forage.

The symptoms are high temperatures, if this one is very intense, it sends a liquid by the hooves; In the mucosa appear blisters, it drool, and nasal discharge. It causes abortion in females and is prevented by vaccinating twice a year.

Anthrax:

This disease kills the animal without any visible symptoms. It bleeds dark red through the animal’s natural orifices and does not coagulate. The corpses must be cremated and buried, the rest of the animals should be vaccinated against anthrax, starting at 6 months of age, twice a year.

Brucellosis:

It manifests itself with successive abortions and in sheep that are infected, in which they are not pregnant causes inflammation in the udders. The disease is acquired by ingestion of contaminated water and fetal wastes that expel during an abortion.

Stallions can be contaminated during intercourse causing, sterility and arthritis. Laboratory tests for the diagnosis of brucellosis are recommended for animals coming from other farms to prevent the spread of the disease.

Diseases of Reproductive Origin:

Toxemia:
