so feces don't attach to the tail causing maggots (fly strike)

How do we dock the tails of sheep?

Explain bridizzio clamps

crimps the testicle cord- the testicle shrinks and atrophies


Do one at a time, if you do both you'll cut off the blood supply to the scrotum = tissue death= gangrene

Explain elastrators

placing a rubber band around the testicle cord, after a week it sloughs off

cuts and crimps

on wooly sheep, done prior to breeding


- trimming off the wool around the stifle and udder area on each side as well as a rear end sanitary shave

Explain the foot of a sheep

- two dewclaws on each foot


- most of the weight of the animal is carried by the hoof wall


-

When are the feet of sheep usually cared for

usually when the wool is being sheared

what is laminitis

peeling to the laminate of the hoof wall

What is a pro in sheep that is a con in cows?

multiple births, the more the better!

What breed of sheep is often used in crossbreeding to promote multiple births?

Romanov

what is the gestation period of a sheep?

5 months

what is nutritional flushing?

1- 1.5 months before birth introduce high quality food to the ewe

Why would you scan a ewe after breeding?

to check how many lambs they're carrying.


- so you can feed accordingly


- and so you can pen up the multiple birth ewes (prevents straying and rejection of lambs)

How do you get an ewe to accept another ewe's lamb?

- smear placenta on her


- vics on the ewe's nose


- restrain the ewe

- ketosis


- milk fever


- diarrhea

What are the most common causes for abortion?

- stress


- poor nutrition


- illness

What would you do if an ewe had a premature birth?

- get a blood or fluid sample


- freeze the fetus if possible


- don't panic

What is copper deficiency or toxicity

sheep store copper in their liver, under stress or too much intake they release it.


can cause ataxia and death

What is pregnancy toxemia?


And when is it more likely to happen?

- happens more often wth multiple births


- the ewe's liver and kidneys can't keep up with her waste and the wase of the lambs, toxins in the blood increase


- may be genetically predisposed

What are your options with pregnancy toxemia?

- you want the lamb(s) out ASAP


- the latter it occurs in pregnancy the better


- can prevent with quality food and not overfeeding

What is meningeal worm?


a parasite


- can't be diagnosed with a live animal


- ends up in spine causing paralysis and eventual death

Who was the miningeal worm first found in?

White tail deer


- snails serve as a vector

What is scrapies

causes swelling of the brain


- rub and scrape against things


- may be connected with mad cow dz


what is the testing for scrapies?

- necropsy


- genetic susceptibility can be checked via genes
