The current pig breeds here can be divided into three categories: the introducing foreign pig breeds, breeding pigs and local pig breeds.  目前我国养猪业正由传统养猪业向现代养猪业转变，无论是养殖 模式、区域布局还是生产方式、生产能力都在发生显著变化。存 在自主创新能力弱、食品安全问题突出、劳动力成本增高、原种 依赖进口、疫病严重、环保压力大、饲料资源匮乏等诸多挑战。 At present, Chinese pig industry is changing from the traditional pig breeding industry to the modern pig breeding industry, whether the breeding model, regional distribution or the modes of production and production capacity are changing remarkably. There are many challenges, such as the ability of independent innovation, the food safety, the increased costs of pig feeding, the original imported and serious disease, environmental protection, feed resources etc..  在养猪过程中 ，饲 料一般占到总养殖 成本的70%左右 ， 是养猪场最主要的 开支。 The cost of the feed is generally accounted for about 70% of the Birth Weaning Growth Finish total cost of farming  猪的生长过程是一个连续渐进的过程 ，对营养的摄取在猪的各个阶 段也是循序渐进各有特点 ，这就涉及到猪场的饲料应用必须按照猪 的生长规律 ，即从小猪—中猪—大猪—母猪这个饲养过程的饲料配 制与原料选用 ，必须区别对待 ，才能达到最大程度节约饲养成本。 In order to achieve the greatest degree of cost savings, the usage of pigs feed need to accord their growth rhythm. 猪从出生到出栏整个生长期中增重与饲料消耗的关系 The relationship of weight gain and feed consumption of pigs from birth to finish
