利用工厂化养猪理论参数动态监测猪群生产

猪群生产是猪场日常工作的核心，一个猪场的效益主要由猪群生产的水平高低而直接体现。而猪群生产中的基础母猪数量、每周配种母猪数、怀孕率、分娩率、窝均产仔数、仔猪存活率、育仔存活率、育成存活率、母猪淘汰率和母猪分娩指数等工厂化养猪参数又是直接衡量猪群生产的水平高低的一系列硬指标，因此，利用工厂化养猪参数可以监测某个时间段的猪群生产的状态。原理是依据现有猪场的基础母猪数量和猪群的某个时间段初期的实际繁殖状态，通过计算机根据工厂化养猪理论参数模拟运算产生出标准猪群生产数据，将之与猪场猪群生产的实际数据相比较，并制出曲线对比图，从对比图中可直观看出猪群生产中的各个环节的优劣，这样就实现了对猪群生产的某个时间段的动态监测功能。

Monitoring swine herd production by parameters of industrialized swine production

Swine herd production is core of routine on swine farm,and benefit of swine farm directly was shown as mainly level of swine herd production.Then swine herd production,parameters of industrialized swine production,including number of basal sow,hybridization sows per week,pregnancy rate,parturition rate,litter size,young piglet livability,raise piglet livability,raise swine livability,sow elimination rate,sow parturition exponent.So the parameters are used to monitor state of swine herd production in a period.According to number of basal sow and practically reproducing state on current swine farm,using computer to calculate standardized swine herd data,compare with the fact data of hogpen swinery production.Then protracting the curve contrastive chart and we could descry the stand or fall of every tache in the swinery production,which make the dynamic inspection function of swinery production in some time come true.
