Beef Cattle Diseases
Anthrax
Spores stay in the ground
 No treatment
 Vaccinate against

BRSV Bovine Respiratory Syncytial Virus
 Basically like pneumonia
 Respiratory disease

BSE




bovine spongiform encephalopathy
progressive neurological disorder of cattle that
results from infection by an unusual
transmissible agent called a prion.
Two cases in 1986
originated as a result of feeding cattle meat-andbone meal that contained BSE-infected products
from a spontaneously occurring case of BSE or
scrapie-infected sheep products
BSE
BVD




Bovine Virus Diarrhea
damage to the digestive and immune systems,
pneumonia, abortions, calf deformities, and
others.
Clinical signs in newborn calves infected with
BVD include fever, nasal discharge, diarrhea,
and inability to move about normally.
Live virus BVD vaccine – could have negative
effects though
Brucellosis
Symptoms

Acute brucellosis may begin with mild flu-like symptoms, or symptoms such as:

Abdominal pain

Back pain

Chills

Excessive sweating

Fatigue

Fever

Headache

Joint pain

Loss of appetite

Weakness

Weight loss
 High fever spikes usually occur every afternoon. The name "undulant" fever is
because the fever rises and falls in waves.
Other symptoms that may occur with this disease:

Muscle pain

Swollen glands

The illness may be chronic and last for years.
Blackleg




The bacteria enters the calf by ingestion and then gains
entrance to the body through small punctures in the
mucous membrane of the digestive tract.
Cattle that are on a high plane of nutrition, rapidly
gaining weight and between 6 months and 2 years of
age are most susceptible to the disease.
The disease is not transmitted directly from sick animals
to healthy animals by mere contact.
The first sign observed is usually lameness, loss of
appetite, rapid breathing and the animal is usually
depressed and has a high fever. Characteristic swellings
develop in the hip, shoulder, chest, back, neck or
elsewhere. First the swelling is small, hot and painful.
Blackleg Muscle
Foot and Mouth



caused by one of the smallest disease
producing viruses known.
Humans do not catch the virus.
The disease is characterized by blister-like
lesions on the tongue, nose and lips, in the
mouth, on the teats and between the toes which
then burst, leaving painful ulcers. The blisters
cause a heavy flow of sticky, foamy saliva that
hangs from the mouth. Infected animals sway
from one foot to the other due to the tenderness
of the feet
IBR
Infectious bovine rhinotracheitis - Red
nose
 This infection usually occurs in the air
passages of the head and the wind
pipe. However, in females this virus also
causes inflammation of the vulva and
vagina and abortion. Abortion occurs
about 20 to 45 days after infection.
 Usually goes with shipping fever

Johne’s disease

a contagious, chronic and sometimes fatal
infection that primarily affects the small
intestine of ruminants.
Leptospirosis


chronic (long lasting) or acute (short lasting)
show signs restlessness, loss of appetite, fever
and nervous system disorders. Although not
seen in every case, the most notable symptom
gives this disease its nickname, "Circling
Disease." Cattle with listeriosis are often seen
walking in circles. Other, more subtle symptoms
include uncoordinated movements, leaning
against objects, and progressive paralysis.
Death can occur within 2 to 3 days after the
onset of symptoms, but cattle can survive for up
to 2 weeks with the disease.
Lumpy jaw

produces immovable hard swellings on the
upper and lower jawbones of cattle,
commonly at the central molar level. It is
caused by an anaerobic micro-organism
Pinkeye
redness and inflammation of the lining of
the eyelid and eyeball.
 non-fatal
 Pinkeye and foot rot are the two most
prevalent conditions affecting all breeding
beef females

Trichomoniasis

venereal disease of cattle that causes
infertility and occasional abortions in cows
and heifers.
Warts
Wart Vaccine
 Cut off and feed to them

Wooden Tongue
Bacteria
 lives in the mouth, invade tissue through
breaks in the lining of the mouth. Any
rough feed can cause mouth abrasions
which allow entry of infection.
 The disease starts suddenly with the
tongue becoming hard, swollen and
painful

Wodden Tongue
Ringworm
Not a worm
 Similar to athletes foot
