Concepts Important to Know and Understand:

An animal’s senses function like those of a human; however,
most animals detect and perceive their environments very
differently as compared to the way humans detect and perceive
the same surroundings.

Handling and restraint is one of the most important jobs when
working in a clinic.

Animals need restraint to prevent injury to themselves, as well
as, those handling them.

Restraint of animals requires knowledge and understanding of
the different types of animals and their behavior.

Abuse of restraint is cruel and inhumane and should not be
tolerated.
Terms to Know:
Evaluations:
Informal

Teacher observation of the students as they engage in discussions and activities related to this unit and the willingness to take
the initiative to follow up on non-graded assignments.
Formal

Evaluation of a cognitive test centered on the technical or subject matter information covered for each of the enabling
objectives.
NOTES:

Students should have access to the “Veterinary Assistant Handbook”, Chapter VI, Sections 5, 6, 7, and 8 by Dr. Floron C.
Faries which is available from Instructional Materials Services, TAMU.

DAY 2
Handling and Restraining Horses
What techniques are used?
Focus Questions
Engaging Activities
1. Are horses dangerous?
1. To introduce the lesson read
“Handling and Restraining
Horses” Chapter VI Section 5
from the “Veterinary Assistant
Handbook”. Be prepared to
discuss the review questions
on page VI-5-4.
Additional Information
An understanding of the horse's
natural behavior patterns and
learning process is an essential
key to safe and effective
management of horses. Some
of the characteristics you must
consider are size, suspicious
nature, telepathic ways, and
their blind spot.
2.
When handling and
restraining
horses
what
characteristics of the horse
should be considered?
Possible replies:

They are big
2. Using slide 2 and referring
to the “Veterinary Assistant
Handbook”, VI-5 discuss the
characteristics of the horse that
one should consider.
Horses because of their large
size can inflict fatal injuries if
they are not handled with
respect. They are not difficult
to handle provided their
suspicious nature is kept in
mind.
When a person is
nervous horses can detect this
and they will become more
excitable. Approaching a horse
on its blind spot can cause the
horse to react defensively.
3. What additional things do I
need to consider?
Possible replies:

Defense techniques

Can be soothed by
being confident and
gentle
3. Using slide 3-4 and by
referring to the “Veterinary
Assistant
Handbook”,
VI-5
discuss these additional factors
Some defense techniques that
can be very dangerous to
humans include:

kicking out in front,
behind, as well as
sideways

rearing up and striking
with their front hooves

biting

when frightened may
bolt
4. What guidelines and skills
and do I need to understand
and use when working with
horses?
4. Using slides 5-6-7 and by
referring to the “Veterinary
Assistant
Handbook”,
VI-5
discuss how to perform the
following:
However, they can be soothed
by gentle reassuring noises
and touch. Handlers who are
confident and authoritative
work very well with horses.
a. Safely position and approach
horse in stall
b. Safely catch horse in stall
c. Correctly halter and attach
lead rope
d. Safely lead horse in and out
of stall and position for release
e. Safely lead horse outside or
in a hallway
f. Back horse and move
hindquarters right and left
g. Safely walk horse into stocks
and out of stocks
h. Safely restrain for hoof
picking, grooming, dental work
and TPR
j. Apply nose and skin twitch
k. Restraint of foal (if possible)

Handling and Restraining Cattle
What techniques are used?
Focus Questions
Engaging Activities
1. Are cattle dangerous?
1. To introduce the lesson read
“Handling and Restraining
Cattle” Chapter VI Section 6
from the “Veterinary Assistant
Handbook”. Be prepared to
discuss the review questions
on page VI-6-5.
2. Why would cattle be harder
to handle compared to other
livestock?

They have horns

They will kick

to the “Veterinary Assistant
Handbook”, VI-6 discuss the
importance of knowing how to
properly handle cattle.
3. What characteristics of the
cow should be considered?

the cow that one should
consider.
4. What guidelines and skills
and do I need to understand
and use when working with
cattle?
4. Using slides 11-12-13 and
by referring to the “Veterinary
Assistant
Handbook”,
VI-6
discuss how to perform the
following:
Additional Information
Cattle are responsible for about
two-thirds of all injuries caused
by farm animals. Handling
cattle is more complex than
handling horses or pigs as they
have a larger body size, are
shy of people, and have less
predictable temperaments. So,
it is important to be able to
understand how they perceive
their environment before you
begin to handle them.
Remember mature males and
females weigh as much as
3000 lb and can easily be
frightened. When they become
agitated,
they
may
unintentionally
crush
their
handler.
Humans
cannot
overpower them with sheer
strength;
therefore
the
successful handler must be
able to outsmart them.
While cattle have poor color
recognition and poor depth
perception, their hearing is
extremely sensitive relative to
humans.
Knowing
these
characteristics, one can better
understand why cattle are often
skittish or balky in unfamiliar
surroundings.

They bite

They are dirty

They are loud
3. Using slides 15-16-17-1819-20-21-22-23 and referring to

following:




Pigs are low to the ground and
have short legs which are
difficult to hold. They are loud
creatures and have a very high
pitch squeal (see table below)
that can injury the handler’s
hearing ability. A grunt, bark or
squeal many times indicates
the pig has become agitated
and mouth chomping usually
precedes aggression.

Materials Services; TAMU
When pigs become aggressive
they can and will bite and use
their “rooting” ability to inflict
pain.
Their bite can be
powerful enough to remove a
person’s finger. “Rooting” is a
normal behavior and the force
applied by their snout can
move or lift very heavy objects.
Food is a high motivator to pigs
and if they are comfortable they
will stand and eat while minor
procedures and examinations
are being performed on them;
i.e. give injections, treat minor
wounds and take temperatures.
Remaining calm, relaxed and
patient and using the proper
restraint and rewards (never
punishment) is the key to
handling pigs. The use of a
soothing voice, comfortable
touch, and food, is the best way
to reduce stress when working
with pigs.

to escape is very strong.

Additional Information
Sheep and goats have a
unique combination of behavior
patterns that directly result from
physiological and psychological
influences. Although goats and
sheep have similar behaviors
these behaviors are very
different from other farm
animals.

Sheep and goats are not as
dangerous as cattle, but they
can certainly hurt a person. A
common accident involving
sheep and goats is being
butted by a mature male and/or
a new mother which can knock
people off their feet
Sheep can be immobilized by
sitting it up on its rump and the
ground. They will feel secure in
this
position
and
stop
struggling.
Although a goat
resents being handled like
sheep this method can be used
for goats. But, most goats are
happy to be restrained with a
collar or adjustable rope halter.
Although it seems natural to
hold and lead goats (or sheep)
by the horns they don't like it
and will usually shake their
heads and fight this technique
of leading or restraint. You
should never hold sheep by
their wool; always hold them
using a natural hold, such as
the jaw or the rear flank.
Restraining lambs and kids is
very simple because they are
lightweight and have no
defenses. Handlers can simply
hold them by the feet or tuck
them under their arm.
Slides 35-36 Handling and Restraint of Livestock Summary
 Practical experience is the best teacher for safe handling of livestock
 Those that have handled animals over a long period of time develop a 'feel' for, or understanding of, animals and their habits.
 Most animals will respond to routine so you need to be calm and deliberate
 Announce your presence well in advance of getting close to an animal, to avoid startling it
 Avoid quick movements or loud noises
 Be patient; never prod an animal when it has nowhere to go
 Respect livestock -- don't fear them
 Move slowly and deliberately around livestock; gently touch animals rather than shoving or bumping them
 Always provide yourself with an escape route when working with an animal in close quarters.
ACTIVITIES:

Demonstrate proper restraint and handling using live sheep and goats along with proper handling and restraint equipment.

Observe and practice these skills by visiting a sheep or goat ranch or veterinary clinic.
