*Continuous Salivation in Cattle*
Continuous salivation in cattle can be caused by various factors, including:
*Oral/Pharyngeal Causes*
1. *Foreign bodies*: Objects stuck in the mouth or pharynx.
2. *Stomatitis*: Inflammation of the mouth, potentially caused by vesicular stomatitis or foot-and-mouth disease.
3. *Actinobacillosis*: A bacterial infection causing "wooden tongue."
4. *Actinomycosis*: A bacterial infection causing "lumpy jaw."
5. *Oral ulcerations*: Trauma, chemical burns, or photosensitization.
6. *Dental disease*: Tooth root abscess or malocclusion.
*Neurological Causes*
1. *Facial nerve paralysis*: Damage to the facial nerve.
2. *Rabies*: A viral disease affecting the nervous system.
3. *Listeriosis*: A bacterial infection affecting the nervous system.
*Toxic Causes*
1. *Organophosphate or carbamate poisoning*: Exposure to certain pesticides.
2. *Cyanide poisoning*: Exposure to certain plants or substances.
*Esophageal Disorders*
1. *Choke*: Partial or complete obstruction of the esophagus.
2. *Megaesophagus*: Enlargement of the esophagus.
*Systemic/Infectious Diseases*
1. *Malignant catarrhal fever*: A viral disease.
2. *Bluetongue*: A viral disease.
3. *Rinderpest*: A historical viral disease.
*Diagnosis*
1. *History*: Onset, duration, exposure to toxins, feed type, and herd involvement.
2. *Physical examination*: Inspecting the oral cavity, palpating the tongue and gums, and checking for obstructions.
*Treatment*
1. *Address underlying cause*: Soft, palatable feed, NSAIDs for pain and inflammation, and maintaining hydration.
2. *Herd-level measures*: Isolating contagious cases and improving pasture management.
*Conclusion*
Continuous salivation in cattle requires identifying and addressing the underlying cause. Proper diagnosis and treatment can help alleviate symptoms and prevent further complications.
