Q

One procedure used to correct a DA is rolling the cow. This works best when…

A

The DA is secondary to another condition such as uterine infection which can be corrected with antibiotics. Then the cow starts to eat which keeps the stomach full and in place.

Q

What causes displaced abomasum or twisted stomach

A

The stomach fills with gas so it pulls the abomasum up towards the cow’s side causing them to stop eating

A viral disease affecting the epithelium of the mouth, tongue, and hooves. It is easily transmitted and can be transmitted to humans. There is no treatment, but most recover. There is a vaccination, but not used in the US because there have not been any recent outbreaks.

87
Q

Usually occurs on Monday mornings after the horse has rested all weekend and consumes a full diet. When the horse begins working, it gets sever muscle cramps causing muscle damage which is cleared through the blood and can cause kidney damage.

88
Q

A

results from damage to a nerve in the autonomic nervous system that travels through the neck and controls several eye functions

  3. the third eyelid protrudes
  4. the eye is sunken in the socket
90
Q

Integumentary system

A

skin, hair, nails, glands, and nerves that protect and regulate the body.

91
Q

foot rot

A

Usually in cattle and sheep, persistent exposure to wet and dirty conditions causes softening of the skin and hooves. Bacteria colonizes between the hoof and skin causing an open infection with a distinct odor. The animal usually loses weight because they won’t go graze. Treatment is topical antibiotic.

92
Q

Why are light colored mammals more likely to develop melanoma than dark colored mammals?

A

Light colors produce pheomelanin which don’t provide UV protection
Dark colors produce eumelanin which does provide UV protection

93
Q

What are the three types of neurons?

A

Sensory
Motor
Interneurons

94
Q

Sensory Neurons

A

help us feel and explore the world around us

95
Q

Motor Neurons

A

Control the movement of the body

96
Q

Interneurons

A

They are the most abundant neurons in the body. They act as the signal controllers within the body, relaying important information from one end of the nervous system to the other.

97
Q

After rest, usually in a horse, it has sever muscle cramps while working. The breakdown products of the muscle has to be discarded which can cause kidney disease

A

Monday Morning Disease/ Typing syndrome

98
Q

What system makes up skin, hair, nails, glands, and nerves that protect and regulate the body.

A

Integumentary system

99
Q

Occurs when bacteria infects the area between the skin and hoof usually in cattle and sheep due to persistent wetness
