11

Cobalt deficiency is related to deficiency of this vitamin

B12

12

Cobalt/Vitamin B12 deficiency is related to

17

How is iodine deficiency treated?

Add IODIZED salt to feed

18

This state is known for causing iodine toxicosis in

small ruminants due to the high levels of iodine

in feed and soil.

are seen with ________ only.

toxicosis

What is the treatment for Lead Toxicosis?

Calcium Versenate IV (Calcium EDTA)

25

A sheep is anorexic and has developed a rough hair coat.

When you arrive, he licks your hands and he has been seen licking

the dirt. Urinalysis reveals a LOW USG.

What is this sheep suffering from and how do you treat?

Provide access to salt SLOWLY! (otherwise-->toxicosis)

26

What types of clinical signs are seen in animals with

salt toxicosis?
