Calendar Prescription Medicine, surgery, management and productivity of beef and dairy cattle. Farm management and production systems and the relationship between management systems, productivity and patterns of disease. The aetiology, pathogenesis and diagnosis of disease. Treatment of disease, including the restoration of animals to normal levels of productivity. The application of health and production programmes to beef and dairy cattle. Pre and co-requisites Successful completion of BVSc III. Restrictions None. E-learning category This paper is web-assisted with most lecture material being made available on the CALVE website under Production Animals and then In addition to lecture material, an up-to-date lecture

2 timetable and other information about assignments and quizzes will be listed periodically on CALVE. Other material on CALVE, particularly Bovine Appreciation Group lecture material (within Production Animals) will be of use. Aim To develop a logical approach to the identification and management of constraints to cattle production systems and to understand the causes, signs, treatments and prognosis of the major diseases of cattle in New Zealand. Learning Outcomes On successful completion of this paper a student will be able to: 1. Describe the seasonal variation in pasture quantity and quality, the changes in animal requirements and how surpluses can be managed and deficits met. 2. Describe the factors that affect oestrous, ovulation, fertilisation, early embryonic mortality and perinatal mortality. 3. Understand bull management and fertility, and the impact of this on herd performance. 4. Describe and perform procedures used to monitor production and be able to investigate areas of poor performance in production and reproduction in a variety of cattle farming enterprises. 5. Understand the diseases of cattle that occur commonly in New Zealand, their economic impact at individual and herd level, and why these may differ in incidence and importance in other countries (the majority of information on trace element deficiencies will be covered in however, this information will be revised and could be examined in ). 6. Know the clinical signs, diagnostic methods, differential diagnoses and prognosis for the major diseases of cattle. 7. Be conversant with the rational and effective treatment regimens for these diseases and be able to calculate the costs of treatment (or prevention) versus the costs of disease. 8. Formulate measures that can be taken to limit or prevent the occurrence of disease, and the influence of animal management and production on the occurrence of diseases. 9. Have developed safe and effective cattle handling skills and be able to perform a complete clinical examination of a cow of any age. 10. Have some experience of common diagnostic procedures including pregnancy testing and treatment techniques including foot trimming, local anaesthesia and ocular surgery. Assessment All assessments relate to the learning outcomes with an emphasis on integrating knowledge from earlier in the course relating to anatomy, physiology, agronomy, microbiology, virology, pathology and pharmacology. The assessments are designed to ensure that this information is integrated in a holistic manner that allows the students to understand the pathogenesis and treatment of disease. It is essential that students can apply this knowledge in a practical setting and is not simply rote learning information. Assessment description Learning outcomes assessed Contribution to (refer above) Paper mark Mid year exam Outcomes 1 to 8 15%

Previous years exam questions (as well as and in the old curriculum) are available in the library. Attendance at all practical classes is compulsory, a roll will be taken. If you cannot attend for any reason please contact the staff member responsible or paper coordinator as soon as possible and arrange for an opportunity to make up this experience. Assignments 1) Teaching Material The best way to fully understand a subject is to be able to explain it to someone else. Students are to work individually and develop teaching material (may be a PowerPoint or word document) that would be suitable for explaining the aetiology, pathogenesis, clinical signs, treatment and prevention of one of the following conditions to a veterinary student at the end of their second undergraduate year. Vagal indigestion. Left displaced abomasums. Hypocalcaemia. Hypomagnasaemia. Ketosis. Rumen acidosis and its sequelae. White line disease. Frothy bloat. Nitrate poisoning. Fog fever. Polioencephalomalacia (thiamine deificiency). Copper deficiency. Johne s disease. Rotavirus diarrhoea in calves. Nutritional diarrhoea in calves. Facial eczema. Endometritis. Anthelmintic resistance. Ostertagiosis. Bovine Viral Diarrhoea. Neospora caninum infection. Anovulatory anoestrous. All students to register which topic they are working on with Jenny Weston (J.F.Weston@massey.ac.nz) by 9 th April. Each topic can only be done by eight students so first in, first served in choosing topics. The assignment is due in by 5 pm on Monday 20 th July. Assignments handed in after this date (without a medical certificate) will be marked but will only receive 50% of the marks. Marking scheme Spelling and grammar 10 marks

4 Clear and logical layout Knowledge Presentation / Innovation 20 marks 20 marks 10 marks Jenny Weston is in charge of this assignment so please see her for any queries. 2) Client Education Brochure Students are to work individually on this assignment. Choose one reasonably common disease of cattle in New Zealand (beef, dairy farming or lifestyle block situation) and develop a client education brochure for this disease that would be suitable as a clinic handout for a client. Your topic should be recorded with Jenny Weston prior to the 3 rd of August students can notify by ; J.F.Weston@massey.ac.nz. No more than six assignments on the same disease will be allowed, first in, first served! For the assignment, assume that a particular disease or management problem has been diagnosed on a farm (dairy or beef) and you have already written a covering letter notifying the farmer of the results. You are including supplementary material (like a client hand-out) to help the farmer with the diagnosed problem this is your assignment. Do not begin with the covering letter. The assignment MUST be word-processed and should be 3-5 A4 pages long (and not too small a font). If you include quite a few tables, pictures, graphs etc then a longer assignment is permissible. Clear layout with plenty of spaces and headings will also be taken into account when judging length. Overly long or short assignments will have 5-marks deducted. The assignment should cover Introduction a brief overview of the disease / problem and why it should be managed. Prevention focus on what can be done now and in future years for a seasonal problem to prevent the same thing happening again. Some problems might take a number of years to bring under control. Treatment some disease problems are likely to be able to be 100% preventable and there may be animals currently affected so if this applies to your topic, include treatment / management of affected animals. For some topics, it may be appropriate to include some costing - this should not be a full economic analysis but could include some prices of drugs (e.g. vaccines, mineral supplementation) especially in cases where there are a number of different preventive / treatment options. When there is more than one option, outline the advantages and disadvantages of each option. Some topics will be very specific and should be covered in a lot of detail, other topics might be quite broad and will only warrant a broad-brush approach to the problem as anything else would take more pages. This will be taken into account during marking.

5 Due in (hand in hard copy to Jenny Weston or the Farm Services Reception) by 5:00pm on September 25 th. Assignments handed in after this date (without a medical certificate) will be marked but will only receive 50% of the marks. All assignments to be handed in to Jenny Weston or at the Farm Services Reception. Requirements to successfully complete the paper Attendance at all practical classes is compulsory. The pass mark for the paper is 60% and all students must also achieve a minimum pass mark of 50% in the end of year written exam. Learning programme and schedule Students should have completed their farm practical work by this stage of the course as an understanding of farming systems is essential to the material in this paper. The lecture and practical schedule will cover the material in the learning outcomes and this will be complimented by the 2- weeks of spring dairy medicine that will be undertaken in August (3 rd 14 th ) as part of the final year compulsory curriculum. Timetable Lectures Friday 10am SSLB7 Semester 1 Friday 11am SSLB7 Semester 1 Tuesday 8am SSLB3 Semester 2 Friday 8am SSLB5 Semester 2 Friday 9am SSLB5 Semester 2 Tuesday 14 th and 21 st July ONLY, lecture at 3pm in AH1. Practical classes Thursday 1pm 5pm Semester 1 & 2 Student time budget There are approximately 60-hours of lectures and it is highly recommended that you attend these. In addition, there will be approximately 36-hours of practical classes. Approximately the same time again ( hours) should be spent in reading around the subject and completing assignments. Timetables for lectures and practical classes will be posted on the CALVE website and updated as required ( click on production animals then ) or notices will be placed on the class notice board in the corridor to Vet 1. Proposed feedback and support for student learning Every attempt will be made to return assignments within a fortnight with feedback but due to the large class size and that for consistency, all assignments will be marked by one person this may take slightly longer. Answers to WebCT quizzes will not be made directly available as these quizzes are likely to be used in future years. The return of exam papers is available through the usual channels. Students are requested to directly approach lecturers with questions during the year and participation in lectures is actively encouraged. Contacting lecturers in person at the end of the lecture or by is recommended. Textbooks and other recommended reading A new textbook has been written by Parkinson, Vermunt and Malmo aimed specifically at cattle medicine under New Zealand / Australian pastoral conditions and is expected to be available early in It is recommended that students intending to work in large animal or mixed practice purchase this book. A folder of reference material will be provided for each student that contains information that supplements the lecture material. Most of the important information for this paper will be covered through the readings or THE BOOK and it is highly recommended that you read this information in advance of the relevant lectures. Lectures will mainly be used to put this material in the context of the major disease

6 conditions that you are likely to encounter on NZ farms and the practical management of these diseases rather than covering the basic information that has already been conveyed in microbiology, virology and parasitology lectures. Other useful texts include: Veterinary Medicine 9 th edition; Radostits, Gay, Blood & Hinchcliff. WB Saunders. Available through the Veterinary Bookshop. Large Animal Internal Medicine 2 nd edition; Bradford Smith; Mosby. Bovine Medicine 2 nd edition; Andrews, Blowey, Boyd & Eddy; 2004; Blackwell Scientific Publishing. The following are recommended as general reading around the paper and may be useful if you intend to go into large animal practice: Milk Production from Pasture; CW Holmes, IM Brookes, DJ Garrick, DDS McKenzie, TJ Parkinson, GF Wilson; Available from Bennetts bookshop. Lameness in Cattle 3 rd edition; Greenough & Weaver, WB Saunders. Mastitis Control in Dairy Herds; Blowey & Edmondson; Farming Press Books, Ipswich, UK. Veterinary Clinical Toxicology 2 nd edition; Parton, Bruere & Chambers. Available from VetLearn. Food Animal Surgery 3 rd edition; Noordsy; Vet Learning Systems, Trenton NJ, USA. Techniques in Large Animal Surgery 2 nd edition; Turner & McIlwraith; Lea & Febiger. Society of Dairy Cattle Veterinarians of the NZVA Proceedings of Conferences available on SciQuest, newsletters also available in the Library or you can subscribe as a student member (see Jenny Weston). A general text on reproduction is also invaluable and two are recommended: Reproductive Management of Grazing Ruminants in NZ (available from the NZ Society of Animal Production). Veterinary Reproduction & Obstetrics 8 th edition; Noakes et al; WB Saunders (covers production animals, equine and companion animals). Conditions for Aegrotat Pass and Impaired Performance If you are prevented by illness, injury or serious crisis from attending an examination (or completing an element of assessment by the due date), or if you consider that your performance has been seriously impaired by such circumstances, you may apply for aegrotat or impaired performance consideration. You must apply on the form available from the Examinations Office, the Student Health Service or the Student Counseling Service. To qualify for an aegrotat pass on the final examination, you must have attempted at least 40% of the total formal assessment and your performance must be well above the minimum pass standard, so that the examiners can be confident that you would have passed the paper if you had completed the final examination. You may also apply for aegrotat consideration for other compulsory assessment elements (such as semester tests) that occur at a fixed time and place if you are prevented by illness, injury or a serious crisis from attending.

7 Plagiarism Massey University, College of Sciences, has taken a firm stance on plagiarism and any form of cheating. Plagiarism is the copying or paraphrasing of another person s work (whether published or unpublished) without clearly acknowledging it. It includes copying the work of other students. Plagiarism will be penalized; it is likely to lead to loss of marks for that item of assessment and may lead to an automatic failing grade for the paper and / or exclusion from reenrollment at the University. Grievance Procedures A student who claims that he / she has sustained academic disadvantage as a result of the actions of a University staff member should use the University Grievance Procedures. Students, whenever practicable, should in the first instance approach the University staff member concerned. If the grievance is unresolved with the staff member concerned, the student should then contact the College of Sciences office on his / her campus for further information on the procedures, or read the procedures in the University Calendar.
