Lesson 3 Advisor’s Guide Lesson 3 • GPP 3 Use Antibiotics Responsibly Key learning objectives: • Identify the principles and guidelines for the responsible use of antibiotics Estimated teaching time: 15 minutes Number of activities provided: 1 Key Terms Antibiotic Antibiotic resistance Antimicrobial Clinical Medication Microorganisms 204 Lesson 3 Slide 1 • Introduction Advisor’s Guide Speaker’s Notes Welcome to lesson number three of the Youth Pork Quality Assurance PlusTM program, “Use antibiotics responsibly”. Slide 2 • Objective Speaker’s Notes The U.S. pork industry has a proud tradition of producing safe and nutritious pork for consumers all over the world. That tradition includes addressing issues arising from the use of animal health products, including antibiotics. At the end of this lesson you will be able to identify important principles and guidelines for using antibiotics responsibly. 205 Lesson 3 Advisor’s Guide Slide 3 • Responsible Antibiotic Use Speaker’s Notes Review Question Q. T/F: Antibiotics are made from molds or bacteria. A. TRUE You may be wondering what type of medication an antibiotic is. Antibiotics are substances that are produced by microorganisms (such as molds or bacteria) and kill or inhibit the growth of other microorganisms, such as bacteria, that cause infections. Antimicrobials are substances that include antibiotics but also include synthetic agents that are created in a laboratory and work in the same manner as antibiotics. Antibiotics and antimicrobials are both types of medication and the term antibiotic is often used to describe antibiotics and antimicrobials. Antibiotics specifically attack bacteria without harming cells belonging to the organism that produced them. Antibiotics, such as penicillin, kill bacteria by inhibiting the bacteria from making cell walls that are needed for their survival, other antibiotics interfere with a bacteria’s ability to synthesize DNA or specific proteins. The use of antibiotics may lead to the development of antibiotic-resistant bacteria that may not be killed by antibiotics and may be more difficult to treat if they infect animals or humans. Therefore, it is the responsibility of every pork producer to use antibiotics responsibly. Involving your veterinarian will help ensure that you are making the proper medication decisions. 206 Lesson 3 Advisor’s Guide Slide 4 • Responsible Antibiotic Use Speaker’s Notes Review Question You and your veterinarian share a responsibility to use antibiotics properly to help prevent resistance. Whether antibiotics are used for disease treatment, disease prevention or to improve nutritional efficiency, you and your veterinarian should carefully consider the issue of antibiotic resistance and the potential impact for particular situations. Resistance is the ability of bacteria to withstand the effects of an antibiotic. Q. T/F: Antibiotics can be used in swine to improve nutritional efficiency. A. TRUE 207 Lesson 3 Advisor’s Guide Slide 5 • Responsible Antibiotic Use Speaker’s Notes Suggested Group Activity Properly Administering Medications Age: All Time: 5-10 minutes Review Questions Q. T/F: Antibiotics can be used as a method of good management. A. FALSE - Antibiotics should only be used to supplement good management. Q. T/F: Responsible antibiotic use is good for animals and humans. A. TRUE Producers like yourself, veterinarians and other food chain participants share the concerns regarding the use of antibiotics as tools utilized in the production of our food supply. The responsible use of these products is beneficial both for the health and wellbeing of the animal and for food safety and human health. It is important that you use antibiotics responsibly to minimize the development of antibiotic resistance, prevent drug residues, preserve their effectiveness and to maintain availability of these products. Antibiotics and other animal health products, while important tools for good animal health management, are only one component of a complete herd health plan. Antibiotics are very important for keeping our animals healthy. Antibiotics should not be used to replace good management, but rather as a supplement to management and should only be used when appropriate. 208 Lesson 3 Advisor’s Guide Slide 6 • Responsible Antibiotic Use Speaker’s Notes Pork producers, like you, use antibiotics for three purposes: treatment of illness, prevention of disease and to improve the nutritional efficiency of their animals. Antibiotics can be delivered through injection, feed or water when used as a treatment to help overcome an illness in animals. Review Questions Q. T/F: Antibiotics can be administered through food, water, or injection. A. TRUE Q. T/F: Antibiotics are only used for the treatment of illness. A. FALSE - Antibiotics can also be used to prevent bacterial infection and improve nutritional efficiency. Antibiotics are also used for prevention of disease in animals that have been, or are being, exposed to a bacterial infection, or when there is a history of disease in an operation. Antibiotics used for prevention are typically given in feed or water although some injectable antibiotics are used to prevent respiratory disease. Improvement of nutritional efficiency is another reason for using antibiotics. When an antibiotic is used to improve nutritional efficiency it is usually in an attempt to enhance pigs’ feed conversion and is delivered in their feed. Q. What are two methods of delivering antibiotics? A. Injection, Feed, Water 209 Lesson 3 Advisor’s Guide Slide 7 • Principles & Guidelines Speaker’s Notes The National Pork Board has developed the following principles and guidelines to help you use antibiotics responsibly: Review Question Q. T/F: Taking steps to ensure biosecurity can also help prevent illness or disease in your animals. A. TRUE First, take appropriate steps to decrease the need for the application of antibiotics. You can do this through good management by having a herd health plan and by providing proper shelter, feed and water for your animals. By taking steps to ensure biosecurity, you can also help prevent illness or disease in your animals. Second, assess the advantages and disadvantages of all uses of antibiotics. Advantages may include improvements in animal health and welfare, while disadvantages might be the development of resistant bacteria. Use antibiotics only when they provide measurable benefits. Be sure to only use an antibiotic if it benefits your animal(s). Use professional veterinary input as the basis for all medication decision-making. If your veterinarian is helping you choose your medications, he or she may suggest a medication or treatment that is not an antibiotic. Involving your veterinarian will help you make the right medication and care decisions for the health and safety of your animal(s). Having a veterinary/client/patient relationship will help ensure that your veterinarian is involved in your production practices and decision-making. 210 Lesson 3 Advisor’s Guide Slide 8 • Principles & Guidelines Speaker’s Notes Another principle to follow is making sure antibiotics are being used for treatment only when there is an appropriate clinical diagnosis. Your veterinarian will be able to help make this decision. Review Question Q. T/F: It is okay to treat all animals with antibiotics, even if they are not considered at-risk. A. FALSE - Limit antibiotic use to ill or at-risk animals. Limit antibiotic treatment to ill or at-risk animals, treating the fewest animals indicated. You should only treat animals that need medication. If an animal does not need medication, antibiotic use should be avoided. 211 Lesson 3 Advisor’s Guide Slide 9 • Principles & Guidelines Speaker’s Notes Review Question Antibiotics that are important in treating antibiotic-resistant infections in human or veterinary medicine should only be used in animals after careful review and reasonable justification. Diagnostic results are one tool that you and your veterinarian can use as justification. You and your veterinarian share a responsibility to use antibiotics properly to help prevent antibiotic resistance from developing. Q. T/F: It is okay to use antibiotics that are important in treating antibiotic resistant infections in people for your pigs without justification. A. FALSE - Such decisions should be consulted with your veterinarian, along with careful review and justification. 212 Lesson 3 Advisor’s Guide Slide 10 • Principles & Guidelines Speaker’s Notes If animal health products are mixed together they may cause problems at the injection site, decrease their efficacy, or require a longer withdrawal period. Only a veterinarian can, under certain circumstances, legally mix together injectable or water medications. Review Question Q. T/F - It is okay for a producer to mix together two different antibiotics. A. False – When antibiotics are mixed together there is a potential for problems with injection site reactions, reduced efficacy, or withdrawal times. Only a veterinarian can legally mix together animal health products under certain circumstances. It is important to properly handle, store and dispose of medication and medicated feed. When using medicated feed or water, feeders and waterers should be adjusted so the medicated feed or water is not wasted and spilled where it might end up in the environment outside the barn. Be responsible when handling and storing medication. 213 Lesson 3 Advisor’s Guide Slide 11 • National Pork Board’s Principles & Guidelines Speaker’s Notes Review Question Q. T/F: Implementing biosecurity measures may decrease the need for antibiotics. A. TRUE Using preventive strategies, such as implementing a biosecurity program, using appropriate animal husbandry, proper hygiene, routine health monitoring and vaccination programs can help decrease the need for antibiotics. You should consider the advantages and disadvantages of all uses of antibiotics, including animal health, well-being, environmental, food safety, and economic impact. The healthier your animals are, the fewer the antibiotics you may need to use, resulting in spending less money and reducing the chances of the development antibiotic resistance. For example, if you watch your pigs every day you may notice one of your animals is sick. You decide, early on, to treat the sick pig with antibiotics. If you were not monitoring your animals closely you may not have noticed the sick pig until the entire pen of pigs became sick. By noticing and treating the pig early you may have prevented the need to treat an entire group of animals. Slide 12 • Take Home Message Speaker’s Notes Some antibiotic-use objectives that you may implement in your operation include: 1. Follow responsible antibiotic use guidelines. 2. Consult your veterinarian before using antibiotics. 3. Implement a herd health plan to help reduce the need for antibiotics. Teacher’s Note: For a full version of National Pork Board’s Principles and Guidelines for antibiotic use please reference National Pork Board’s Take CareTM Program. As a pork producer it is your responsibility to use antibiotics properly. 214 Lesson 3 Slide 13 • Summary Advisor’s Guide Speaker’s Notes As a producer, you have taken on the responsibility to properly care for your animals, following the Responsible Antibiotic Use Principles and Guidelines and using medications properly will help prevent antibiotic resistance as well as violative residues.
