possible performance实现最佳的生产性能 utilization of potential充分利用动物潜力.is to establish an optimal environment in the barn 是非常重要的基本因素,A good climate system plays an essential role in reaching these targets良好的气候控制系统在实现上述目标的过程中起到不可或缺的作用,2023/1/21,4,Geographic location of the project项目的地理位置,Climate zone 气候区域 Altitude,rain/snow fall,wind,humidity,min/max temperatures etc.海拔、雨雪风等气候状况、湿度、最高/最低温度等,2023/1/21,各猪舍最佳温度,2023/1/21,6,Too hot舍内过热,Pigs are usually clean animals.猪通常是喜欢干净的动物。,Dirty pigs send warning signals猪变脏即为一种警告信号,?Too high room temperature 室内温度是否过高?Sufficient ventilation system 通风是否充足?Pen design and size.围栏设计和尺寸是否适当Results 结果=Heat stress 热应激 Bad air quality 空气质量差 Increased mortality 提高死亡率 Less daily gain 降低日增重 Increased manpower 增加工作量,2023/1/21,Viggo Poulsen,7,Too cold舍内过冷,Open floor 漏缝地板?Open penning 开放式围栏?Heating 是否加热?Room temperature 室内温度?Ventilation,-type 通风类型?Air speed 风速?,2023/1/21,8,The pig regulates body heat in four ways 猪以四种方式调节体温:radiation 散热(loss to the surrounding ceiling and walls)（热量散失到周围的吊顶和墙壁 conduction 热传导(heat conducted from the body by whatever it touches)（热量传导至其接触到的物体）convection 热流传递(loss to air flowing over the body)（散失至通过身体的气流中）latent heat loss 潜热散失(loss through evaporation of body moisture)（体表水分蒸发散失热量）,Latent潜热,Radiation 散热,Convection 热流传递,Conduction 热传导,2023/1/21,9,Cooling 降温.,Chill effect 风冷效应.,2023/1/21,10,Chilling is one of the most important contributors to baby pig mortality in farrowing It makes the piglet weak and sluggish,leaving it vulnerable to other dangers such as crushing and starvation.风冷是哺乳仔猪死亡率的最重要的影响因素之一，会使仔猪体况变差、反应迟钝，进而使其易于遭受挤压或饥饿等其他风险。,2023/1/21,11,Added heating is needed when pigs are not able tokeep comfort temperature by own heat production.Additional heat can be supplied either by gas or warm water for room or by warm water or electric for zone heating(Heat plate/lamps)当猪通过自身产热无法保持其所需的舒适温度时，需要对舍内进行加热。加热的方式有下列几种：全舍的水暖加热或燃气加热，以及局部电加热（加热板/保温灯）,2023/1/21,12,Impact of high temperatures 高温的影响,Low feed intake 降低采食量High water intake 提高饮水量Low daily weight gain 降低日增重Risk of heat stress and higher mortality 增大热应激的风险并提高死亡率,Impact of low temperatures 低温的影响,High feed intake 提高采食量Low daily weight gain 降低日增重Higher medical cost 提高药物成本Higher mortality 提高死亡率,Conclusion of high or low temperatures:Slow growth performance-Higher mortality-Slower turn over of pigs higher medical cost-more labor required 高温或低温状态下：降低增重性能 提高死亡率 降低猪群流转速度 提高药物成本 增加工作量,2023/1/21,13,Most common types of modern ventilation systems常用的现代化通风系统类型,Negative pressure systems with fresh air inlets 负压通风系统Equal pressure systems 等压通风系统Positive pressure system 正压通风系统 Tunnel ventilation 纵向通风系统 Combi-tunnel ventilation 联合通风系统,2023/1/21,14,Negative pressure system with fresh-air inlet valves采用进风小窗的负压通风系统,2023/1/21,15,15,Equal Pressure

winter冬季采用横向模式 Tunnel mode in summer夏季采用纵向模式 Heating/cooling,humidification实现加热/降温和加湿等功能,Optimal climate 365 days and nights per year全年适用的气候控制系统,2023/1/21,19,2023/1/21,20,Balance between cost and air-quality在成本和空气质量之间取得平衡,Demands of the in-door climate 室内气候条件需求:NH:max.20ppm,better 10 ppmCO2:max.3000ppm,better 2500ppm%RH:max.80%(challenging in Asia)Power consumption(功耗):Watt/m3 air exchanged,2023/1/21,21,21,Basic requirements for optimal function实现最佳功能的基本要求,Inspect pigs behavior before enter 进猪前检查猪群行为How they rest,are they over active,body conditions,using the resting area of the pen?它们的躺卧姿势如何、是否精力过剩、体况如何、休息区布局如何？Tight house construction 房舍建筑的空气密闭性 Orientation of interior/penning 内部设施/围栏的方向 Avoid obstructions for free air movement 避免出现任何阻碍气流的障碍物,2023/1/21,Climate is part
