Term
How is verbal restraint used for sheep and cows?
Definition
Talk calmly but loudly. For cows, it is mainly to let them know where you are. For sheep, it has a calming effect.
Term
What is the flight zone?
Definition
area surrounding an animal that will cause it to move away from you if you cross into it
Term
What is the point of balance?
Definition
The point of balance is located at the cow's shoulder. If you move past the shoulder going toward the rear, the cow will move forward. If you move toward the head from the shoulder, the cow will stop and turn to move away from you.

what are the three types of restraint?
Definition
verbal, physical, chemical
Term
What is the most important type of restraint that you should always use?
Definition
verbal
Term
What is the difference between a sedative and an anesthetic?
Definition
sedatives - animal remains conscious
anesthetic - animal is unconscious
Term
What are some things to consider when selecting a restraint method?

Proper way to approach cattle
Definition
Use your voice, touch them as you move in, move slowly keep disruption of animal to a minimum
Term
What is hazing?
Definition
Used to drive cattle to a particular location - essentially making yourself look bigger with your arms out to the side - often combined with point of balance/flight zone signals
Term
what is a lariat?
Definition
long, strong, but light rope with a sliding noose at one end
Term
How do you use a lariat?
Definition
Toss the loop over the animal's head so that it encircles the neck. Pull the loop tight and wrap the standing part of the rope around a sturdy post twice. Pull or haze the animal toward the post while simultaneously shortening the standing part of the rope.
Term
Halters can only be applied when:
Definition
the animal is docile, or when leading a dairy cow to another location, or when the cow is in a headgate
Term
Halters are usually used when
Definition
moving a dairy cow from one location to another, or when the cow's head needs to be restrained for a procedure
Term
Why are nose tongs used?
Definition
provide added restraint to the head. may attach to headgate if you are working by yourself
Term
What is a flank clamp and when would you use it?
Definition
a flank clamp is a metal bar that is clamped around the animal's flank, putting pressure on the flank and the lumbar vertebrae on the opposite side. They are used when working near the hind end of a cow that may kick
Term
What should be done prior to moving an animal into a chute?
Definition
Prepare the route and chute system, the headgate should be well lit, make sure that the chute and headgate are in working order
Term
what is the definition of a headgate?
Definition
A restraint device that can be closed about the neck of the animal that prevents its forward and backward movement, rendering maximum safety for animals and handlers when used properly.
Term
Reasons why you would need to immobilize the head
Definition
dehorning; detailed examination of head, mouth, eye, or hoof; collecting blood sample from jugular vein, other surgical procedures involving the head or neck
Term
When is it possible to work outside a pen?
Definition
if the pen is not too large, and if the walls do not extend from floor to ceiling.
Term
How do you work outside a pen?
Definition
stand on the outside of the pen or on a catwalk adjacent to the side of the pen. you must use a lariat - may need the owner to go in and move them towards you
Term
What would be some reasons to choose to work outside of a pen?
Definition
You are concerned for your safety, you are working alone
Term
When would it be appropriate to work inside a pen?
Definition
Your safety is not in jeopardy, you are familiar with the animal, you need to haze a potentially aggressive animal from a large pen toward a chute/headgate system, you need to work on a calf that is nursing its dam
Term
when working inside a pen, make sure that you....
Definition
speak to the animal, open the gate deliberately, make all movements deliberate, make sure you have an escape route
Term
concerns when restraining a calf that is in a herd
Definition
calves will seek protection form the herd and mother. Mothers with young can be very dangerous, and there is also a risk of being trampled by the herd. Calves that have never been handled will be nervous and may be aggressive
Term
how to restrain a calf
Definition
1)Have owner/farmer move calves into small pen
2) Always catch mother first and keep a close eye on her
3) Crowd into a corner of the pen, cradle the calf, and put into lateral recumbency much like a large dog
4) Make sure that the cow can always see the calf
Term
when and how would you put a halter on a calf?
Definition
When the calf is over 4 weeks old, tie it short
Term
Why is the sub Q route preferred over the IM injection route?
Definition
IM injections can cause scarring and reduce meat quality and value
Term
Explain the technique that may be used to encourage a cow to stand
Definition
tap, slap, or poke the back, rib, or thigh area of the cow. If she still resists, you may thrust your knees into the back and rib area.
Term
Where do you listen to ruminations on a cow?
Definition
left paralumbar fossa
Term
What are you examining the milk for in the strip test?
Definition
blood, flakes, color change, serum, wateriness, clots
Term
What are the benefits of the strip test?
Definition
Identifies clinical mastitis, stimulates milk let-down, shorter milking time, removal of foremilk
Term
Why is removing the foremilk beneficial?
Definition
May reduce contamination of milk machine, and contamination from one cow to another. Increases quality of milk being produced
Term
Why is subclinical mastitis costly for the farmer?
Definition
creates scar tissue which reduces quantity of milk produced for life, higher somatic cell count in the tank means less money for the farmer
Term
What important information is obtained from the CMT test?
Definition
Aids in detecting herd mastitis problems, determining faulty milking procedures or machines, determining effectiveness of teat dips and dry cow treatment programs, detects individual cow and quarter infections
Term
some advantages of the CMT
Definition
fairly accurate, inexpensive, sensitive, simple, little equipment, may be used on bucket or bulk tank samples, easy clean-up, environmental temp or foreign material have little effect on the test
Term
disadvantages of the CMT
Definition
scoring may vary, must be consistent as possible, scores represent a range, false positives occur frequently, acute clinical mastitis will not score positive
Term
Why do false positives occur frequently with the CMT?
Definition
Cows that have been fresh less than ten days, cows that are nearly dry
Term
Why does acute clnical mastitis not score positive on the CMT?
Definition
somatic cells will all be killed from the toxins produced by the infecting organism
Term
What must be done after any milking procedure?
Definition
dip teats with antibacterial teat dip
Term
What is a steer?
Definition
castrated male
Term
define mastitis
Definition
inflammation of the mammary gland
Term
what is a freshening heifer?
Definition
young bovine female that is calving it's first calf
Term
Why is it important to minimize stress when working with sheep?
Definition
Suppresses their immune system, causes them to get sick and/or go off feed, resulting in slower growth rate and less money for the farmer. (Poor reproduction, growth rate, fleece quality, high lamb mortality)
Term
What stress factors affect sheep?
Definition
Being alone, different handlers, drastic changes to or being in a new environment, seeing and smelling predators
Term
Why are llamas, great pyranese dogs, or donkeys often kept with a flock of sheep?
Definition
to defend flock from predators (may see you as a threat also)
Term
Explain how avoidance/follow the leader behavior of sheep is the key to moving the flock.
Definition
Use natural flocking instinct along with flight zone/point of balance to move them in the direction you want. However, you must alternate pressure (unlike cattle) and back off when they begin to move. Otherwise you will lose control of the flock.
Term
What is the appropriate way to approach a flock in a field?
Definition
do not approach head-on - come around the side from the back
Term
Can you use chutes/headgates with sheep?
Definition
Yes, it is similar to cattle, except smaller
Term
Can you halter sheep?
Definition
Yes, but they are rarely halter broken. A much better method is to use your hands
Term
How do you capture a sheep by hand?
Definition
Use a small pen - approach one step at a time, grab flank and pull up as hard as you can, grab under the mandible quickly
Term
define wether
Definition
castrated male sheep or goat
Term
List the harmful problems that may occur if the ruminant's hooves were left untrimmed.
Definition
Uneven growth; corkscrew claws, scissor claws Sores Abscesses Hoof rot
Term
What is the most significant risk and primary concern(s) when catching and restraining sheep.
Definition
Sheep may cause injury to themselves and may even exhaust themselves to the point of hyperthermia
Term
What is the proper restraint method for trimming a sheep's hooves?
Definition
set up
Term
What are two ways cattle may be restrained for hoof trimming?
Definition
Use a tilt table. This table is a hydraulic table that will tilt the cow or bull on it's side, which will then enable us to have access to their hooves for trimming. The second option is to use a trimming chute, which also has a headgate to restrain the cow or bull. One in the chute the each leg may be lifted mechanically using ropes or chains.
Term
What are the three main reasons we need to trim hooves in ruminants?
Definition
Prevent lameness and disease, or for show purposes
Term
Proper way to trim small ruminant hooves
Definition
Can use pruning shears - first clean the hoof - cut away excess hoof wall - may need to trim some of the sole or heel - make the sole parallel to the coronet band - stop if you see pink or they start bleeding
Term
how is trimming cattle hooves different?
Definition
same principle, but cattle's hooves are obviously thicker. First cut with the nippers and then use the grinder to smooth - be aware that a drastic change of angle will cause soreness.
Term
How do you evaluate the quality of an equine hoof trim?
Definition
should be uniform - no flaring or curling of the toe. hind hooves should have same angle and length - front hooves should have same angle and length. sole should be flexible but not too thin. hind hoof has a slightly greater angle than the front hoof.
