Pigs will always tell you how they feel You have to recognize what the pig is telling you You have to recognize the symptoms and understand the problem(s) and how to improve the environmental status of the pig’ living conditions 影响猪只生长表现的因素Ceiling to pig performance 营养 Nutrition 环境和管理 Environment Management 疾病 Disease 猪（遗传） Pig (genetics) 一头猪如果要发挥其遗传潜力，达到生长的最大化，往往要受到管理、环境、疾病的限制A pig’s ability to maximize growth to its full genetic potential is frequently limited by management, environment and disease 环境 Environment 环境基本上是影响猪生长潜力的最大单一因素 Environment is perhaps the largest single factor influencing pigs’ growth potential 环境通常因为温度、猪群状况、空气质量等因素对猪的生长表现起到最大的限制作用 Environment frequently puts a ceiling on pig growth performance because of thermal, social and air quality stresses 环境 Environment 当环境应激加上较差的管理，会大大降低免疫功能，结果增加了患病的可能性。 When these stresses are coupled with marginal management practices, environment will compromise immune status and result in increased disease incidence 营养—环境Nutrition Environment 你可以给猪提供最好的营养，但猪不一定因此会有最佳的生长表现。原因是环境应激限制了猪生长潜力的发挥。 You can provide the very best nutrition to a pig, but the pig may not perform accordingly, since the environmental stresses limit its growth potential 限制因素的消除Ceiling removal 消除了影响生长潜力的限制因素，你可以利用最适宜的营养，使猪的遗传潜力得到最大程度的发挥。 By removing these ceilings which limit growth potential, you can capitalize on an optimum nutrition program to achieve the pig’s maximum genetic potential 临床症状Clinical symptoms 症状 Symptoms 症状是指机体正常功能的改变所表现的失常状态或疾病的表现 Symptoms are changes in normal bodily functions or appearance indicating disorder or disease 猪栏内的症状Pen Symptoms 堆叠 Piling 拥挤 Huddling 溜边 Avoiding areas of the pen 在躺卧区域内排粪 Dunging in sleeping area 堆叠和拥挤Piling and Huddling 通常发生在因保温差或贼风导致的冷应激，或者是有效温度低于猪的最低临界温度 Frequently occur when pigs are subjected to cold stress caused by drafts and/or when effective temperature is less than the temperature in the pigs’ thermoneutral zone 溜边Avoiding areas of the pen 当猪栏内有贼风、有害气体增加、没有空
