What
is
Coccidiosis
?
Definition
of Coccidiosis in Cattle
Cocciodiosis
, a protozoan parasite of cattle, is caused by the genus Eimeria
The most common species affecting cattle include
E.
bovis
,
E
zuernii
, and
E
auburnensis
The disease is common in young cattle up to two years old.
Signs and symptoms of Coccidiosis in cattle
Watery
feces, with little or no blood and shreds of epithelium and mucus
Animals may die from secondary bacterial complications or concurrent infections (e.g. corona virus infection) that develop ;
Fever
become
anorectic
Signs and symptoms of Coccidiosis in
cattle
Cont
…
depressed
dehydrated
loss of weight
Eimeria
zuernii
is highly pathogenic causing bloody diarrhea
Coccidiosis in cattle
Pharmacological Treatment of Coccidiosis in
Cattle
Amprolium
Decoquinate 167g/10kg of feed for 28 days, or
Do not mix with drugs having similar action
Avoid direct contact with skin and wash thoroughly after handling the product
Supportive therapy
The most effective treatment for the already sick animal is fluids
Contraindications in Treatment of Coccidiosis in Cattle
Sulfamethazine
Allergy and hypersensitivity
Decoquinate
Do not use in cases of hypersensitivity to the active substance or to any of the excipients
Monensin
Hypersensitivity to
Monensin
Common
Side Effects and Adverse Drug Reactions of Drugs Used in Treatment of Coccidiosis in Cattle
Monensin
high dose may result in reduced weight gain,
Reduced voluntary feed intake
Reduced milk fat percentage
Increased incidence and treatment of cystic ovaries and metritis
Reduced conception rates
Activity:
Brainstorming
What
are the prevention and control measures for Coccidiosis in Cattle?
Prevention and Control of Coccidiosis in Cattle
Prophylaxis
Control
Housing and ventilation deficiencies should be corrected
Do not mix different age groups of calves, avoid fecal contamination of feed.
Isolation of the affected animal(s) to prevent increased contamination of the premises
Key Points
Coccidiosis
is caused by protozoan parasites of
Eimeria
species
The most effective treatment for the already
sickcattle
is supportive therapy (fluids) and antibiotics to ward off secondary infections
Prevention focuses on preventing
fecal
contamination of the cattle’s environment, feed and water
Evaluation
What
is Coccidiosis?
What are the common signs and symptoms of Coccidiosis?
What is the pharmacological treatment of Coccidiosis?
What are the control measures against Coccidiosis?
