微生物发酵床大栏猪舍育肥猪群管理隔离栏结构设计

微生物发酵床育肥猪大栏养殖系统单栏同期养殖育肥猪1500头，因猪群过大，管理难度很大。由于猪个体大小、健康、抗病、竞争能力的不同，取食、饮水、运动、睡卧、争斗等行为难以观察，无法分类管理，造成小猪更弱，弱猪更不健康，病猪漏治，引起猪群体管理的缺位。作者设计了微生物发酵床大栏猪舍育肥猪群管理隔离栏结构，提出猪群渐进分栏管理方法，将微生物发酵床大栏猪舍猪群管理隔离栏分成8个区域，其中位于微生物发酵床的两侧4栏作为隔离栏，主要功能是用于隔离病、弱、小、差的猪。主体栏分割为4个渐进隔栏，分别隔离大小不同的育肥猪。在管理上，利用渐进隔栏对不同类型的猪进行分类管理，将大小相同的猪归到同一栏，将病、弱、小、差的猪归到隔离栏，动态地管理不同类型的猪。待育肥猪长至75kg左右，猪群的健康状态稳定，可以打开所有的栏门，让各栏贯通，猪群有更大的运动空间。利用这一方法，可提高病猪的治疗能力，促进弱猪的康复能力，提升同期猪群的管理水平，为微生物发酵床育肥猪大栏养殖系统健康运行提供基础。

Barrier Design for Finishing Pig Population Management in Large-scale Piggery with Microbial Fermentation Bed

In a large-scale piggery with microbial fermentation bed,1 500 pigs could be raised at the same time,which was so large that the management was very difficult.The pig population varies at body size,health condition,disease resistance,competition ability,and it is difficult to observe the pig behaviors of feeding,drinking,moving,sleeping,fighting,etc,which results in lack of pig population management for weak and ill ones.Barrier structuredesign for large-scale piggery with microbial fermentation bed was used for pig population management,and thepigs were gradually fed separately.The microorganism fermentation bed swine piggery was divided into eight big barareas,4 barriers located in both sides of the microorganism fermentation bed were for the sick,weak,small andinferior pigs.The body field was divided into 4 parts to gradually isolate different sizes of finishing pigs.With thedesign,the management ways for pigs at different growth stage varied by the barriers,which classified the healthypigs from the sick ones,and made them fed separately.When the finishing pigs reached 7 5 kg,and kept healthystably,all bar doors could be open for pigs to move freely in a larger area.The barrier design was proved to haveadvantages in treatment of sick pigs,rehabilitation of weak pigs and management of the pigs at the same period inthe large-scale piggery of microbial fermentation bed.
