AGRICULTURE EDUCATION Introduction to Veterinary Medical Science Unit H: Restraint of Animals Terminal Objective: To identify and practice methods used to handle and restrain animals. Lesson: Topic H-2 Handling and Restraint of Livestock Lesson objective(s): Identify and practice methods used to handle and restrain of farm animals. Essential Question(s): What skills do I need to be able to work safely with farm animals? Estimated Time: 5 periods Instructional Mode: Lecture, whole group, partners, and individual Course TEKS: The student learns the employability characteristics of a successful worker in the modern workplace. The student shall: Enabling Objectives: Identify the methods used in handling and restraining horses, cattle, sheep, goats, and pigs. (c)(1)(C) demonstrate knowledge of personal and occupational safety practices in the workplace. (c)(1)(D) apply competencies related to resources, information, interpersonal skills, and systems of operation in veterinary medicine. TAKS Objectives English LA: Math: Science: Social Studies: 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. National Ag Safety Database (NASD) is an information clearinghouse for agricultural safety related documents. http://www.cdc.gov/nasd/contact.html 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.

Possible replies: Horns They will kick 3. Using slide 9-10 and referring to the “Veterinary Assistant Handbook”, VI-6 discuss the characteristics of 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.

Focus Questions Engaging Activities 1. Are pigs dangerous? 1. To introduce the lesson read “Handling and Restraining Swine” Chapter VI Section 7 from the “Veterinary Assistant Handbook”. Be prepared to discuss the review questions on page VI-7-4. 2. Pigs are so cute; why are they hard to handle? 2. Using slides 14 and referring to the “Veterinary Assistant Handbook”, VI-6, discuss the importance of knowing how to properly handle pigs. 3. What characteristics make pigs hard to handle and restrain? Possible replies: They bite They are dirty They are loud 3. Using slides 15-16-17-1819-20-21-22-23 and referring to the “Veterinary Assistant Handbook”, VI-7, discuss the characteristics of the pig. 4. What guidelines and skills and do I need to understand and use when working with pigs? 4. Using slides 24-25 and by referring to the “Veterinary Assistant Handbook”, VI-7, discuss how to perform the 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.

Faries available from Instructional 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.

ACTIVITIES: Demonstrate proper restraint and handling using a live cow along with proper handling and restraint equipment. Observe and practice these skills by visiting a pig farm or veterinary clinic. NOTES: DAY 5 Handling and Restraining Sheep and Goats What techniques are used? Focus Questions Engaging Activities 1. Are sheep and goats 1. To introduce the lesson read “Handling and Restraining dangerous? Sheep and Goats” Chapter VI Section 8 from the “Veterinary Assistant Handbook”. Be prepared to discuss the review questions on page VI-8-3. 2. Mary had a little lamb so why is restraint hard? 2. Using slides 26-27-and referring to the “Veterinary Assistant Handbook”, VI-8 discuss how to handle and restrain sheep and goats. 3. What characteristics make sheep and goats hard to handle and restrain? Possible replies: They will butt you with their head They do not like being held by the horns 3. Using slides 28-29-30-31-32 and referring to the “Veterinary Assistant Handbook”, VI-7, discuss the characteristics of sheep and goats. 4. What guidelines and skills and do I need to understand and use when working with pigs? 4. Using slide 33-34 and by referring to the “Veterinary Assistant Handbook”, VI-8 discuss how to perform the following: 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. Reference Materials Animal Care Training – ppt Handling and Restraint of Animals – Slides 26-27-28-2930-31-32-33-34 “Veterinary Assistant Handbook”, VI-8 by Dr. Floron C. Faries available from Instructional Materials Services; TAMU 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. NOTES: DAY 6 Optional Lesson “The Use of Ropes” How are ropes used? Focus Questions Engaging Activities 1.
