Advanced Training in Intensive Livestock Health and Production

广泛的自由贸易、高效的国际运输、知识和技术传播、资源和劳动力成本以及立法负担使集约化畜牧业（猪和家禽）行业具有激烈的竞争力。对生猪生产的补贴相当于经合组织国家平均农场价值的23%，这是英国生产商无法获得的，这增加了竞争压力。尽管养猪业和家禽业规模庞大，但英国在肉鸡和猪肉生产方面的贸易逆差（DEFRA，2007年，2008年）。竞争压力和技术进步推动了生产效率的显著提高。例如，在肉鸡生产中，日增重翻了一番，从1970年的30克/天增加到2003年的60克/天，同期食物转化效率（每公斤活重增加的千克饲料）从2.3提高到1.8。生产力的提高主要与遗传改良、营养改善和疾病控制方面的巨大进步有关，而这些又使集约化程度提高，从而提高了生产效率。由于许多简单的问题已经找到解决办法，而且现在需要进行技术上更复杂的创新，因此改进的速度已经放慢。在全球范围内，生产力需要进一步逐步变化，以满足预测的人口增长和动物蛋白消费量的增加，到2030年将增加一倍。发展中国家的繁荣和社会变革威胁到英国的粮食安全，历史上，当国内生产不足时，英国的粮食安全一直由进口来保证。随着生产的增加，增加“足迹”（淡水消耗、温室气体排放和土壤退化）对环境是不利的。畜牧业最好由能够将知识和理解从生产动物的DNA整合到消费者的饮食中，并在经济现实，商业效率和道德约束的背景下提供服务。在英国，集约化畜牧业生产所需的兽医和相关科学技能越来越短缺。这对英国的粮食安全构成了真实的结构性危险，并导致经济竞争力的缺乏。在英国，只有3.8%的兽医专门从事生产动物实践，由此推断，从事集约化畜牧生产的兽医比例较小（RCVS调查，2010年）。虽然兽医具备全面的能力来应对食用动物所面临的主要挑战，但他们没有接受过作为集约化畜牧兽医有效运作所需的高度专业化培训。目前，英国持有家禽和猪医学专业文凭的兽医人数分别为6人和12人（RCVS Register 2009），其中72%在1987年之前获得文凭，表明人口老龄化。只有8个英国的欧洲学院外交官存在，只有6个欧洲外交官在相应的家禽科学学院，反映了欧洲大陆的技能短缺。美国也存在类似的短缺。此外，具有鸡和猪生物学专业知识的基础科学家或应用科学家很少，对土地研究规定的审查（HEFCE，2007年）发现，从事畜牧生产课程的学生很少。支持的理由是：尽管有一个高效的猪和家禽产业，英国在猪和家禽产品方面的贸易差额是负数。为了保持竞争力，促进全球消费，确保英国的粮食安全，减少对环境的影响，需要大幅提高生产力。需要从DNA到饮食的整体专业知识来支持该行业。支持该部门的熟练兽医和科学家队伍数量正在减少。

Extensive free trade, efficient International transportation, knowledge and technology dissemination, resource and workforce costs and legislative burden make the intensive livestock (pigs and poultry) industries searingly competitive. A subsidy for pig production amounting to 23% of value at farmgate averaged across OECD countries which is not available to UK producers exerts increased competitive pressure. Despite large efficient pig and poultry industries the UK has a negative trade balance in both broiler and pig meat production (DEFRA 2007, 2008). Competitive pressure and technological progress have driven remarkable improvements in production efficiency. For instance in broiler production daily weight gain doubled, from 30 grammes per day (g/d) in 1970 to 60 g/d in 2003 and food conversion efficiency (kilogrammes (kg) feed per kg live weight gain) improved from 2.3 to 1.8 over the same period. Productivity gains have been primarily associated with genetic improvement, better nutrition and dramatic advances in disease control which in turn have permitted greater intensification and thus production efficiency. The rate of improvement has slowed as solutions have been found to many straightforward problems and a requirement now exists for more technologically sophisticated innovation. A further step-change in productivity will be required on a global scale to meet the predicted population growth and increased consumption of animal protein which is set to double by 2030. The improved prosperity and social changes in developing countries threaten UK food security which historically has been assured by importation when internal production is inadequate. It is environmentally undesirable to increase the 'footprint' (fresh water consumption, greenhouse gas emissions and soil degradation) as production increases. The livestock industry will be best served by a workforce capable of integrating knowledge and understanding from the DNA of the production animal to the diet of the consumer and in the context of economic reality, business efficiency and ethical constraint. There is a growing shortage of veterinary and associated scientific skills provision for intensive livestock production in the UK. This presents a real, structural danger to UK food security and is contributing to lack of economic competitiveness. Only 3.8% of veterinarians in the UK work in exclusively production animal practice and by inference a smaller proportion work in intensive livestock production (RCVS survey 2010). Whilst veterinarians qualify with an all round ability to deal with the major challenges that arise with food animals, they do not receive the highly specialised training required to operate effectively as intensive livestock veterinarians. Currently veterinarians holding specialist diplomas in poultry and pig medicine in the UK number 6 and 12 respectively (RCVS Register 2009) and of these 72% acquired their diplomas before 1987, suggesting an ageing population. Only 8 UK based European college diplomats exist and there are only 6 European diplomats in the corresponding poultry science college, reflecting the skills shortage in mainland Europe. A similar shortage exists in the USA. Furthermore there are few basic or applied scientists with specialised knowledge of chicken and pig biology and a review of provision for Land Based Studies (HEFCE 2007) identified the paucity of students engaged in courses on livestock production. The case for support is that: Despite an efficient pig and poultry industry the UK has a negative trade balance in pig and poultry products. Substantial improvements in productivity will be required to remain competitive, to contribute to global consumption, to ensure UK food security and to reduce environmental impact. Holistic expertise will be required from DNA to diet to support the industry. There is a small declining cadre of skilled veterinarians and scientists supporting the sector.
