微生物发酵床大栏猪舍育肥猪群管理隔离栏结构设计(英文)

目的]微生物发酵床育肥猪大栏养殖系统单栏同期养殖育肥猪1 500头,由于猪群过大,管理难度很大,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,造成猪群体管理缺位,亟需进行改善。方法]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,分别隔离不同大小的育肥猪。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。等到育肥猪长到75 kg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。结果]利用这一方法,提高了病猪的治疗能力,促进了弱猪的康复能力,提升了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了基础。结论]发酵床养殖模式可显著改善猪舍环境和猪的福利状况,并改善生产性能和猪肉品质,其安全性和经济性优势明显,应用前景广阔。

Barrier Structure Design for Fattening Pigs in Large-scale Pig House with Fermentation Bed

Objective] The large-scale single-column fattening pig house with fermen- tation bed could hold 1 500 heads of fattening pigs. Since the number of pigs in piggery is too large, the management is difficult. The behavior of feeding, drinking, movement, sleeping, fighting of pigs is difficult to handle. The pigs cannot be man- aged well, resulting in the enhanced weakness of piglets, enhanced illness of weak pigs and missing treatment of ill pigs. The management for the pig populations is not satisfactory, and thus, it is needed to improve timely. Method] The barriers for the fattening pigs in the large-scale pig house with fermentation bed were designed. The single management for single fattening pig was proposed. The large-scale fat- tening pig house was divided into 8 regions. Among them, 4 regions were located in both sides of the fermentation bed. Their main function was to separate ill, weak, small and bad pigs. In addition, the main column was divided into 4 gradual barri- ers. They were used to separate different-size fattening pigs. In view of manage- ment, the different-type pigs were managed dividedly with the gradual barriers. The equally-sized pigs were concentrated into one column. The ill, weak, small and bad pigs were isolated into barriers. Thus, the dynamic management was adopted. Until the fattening pigs grew up to 75 kg and their health was stable, the barriers among the columns were canceled to mix the pigs again and guarantee the pigs more gymnastic space. Result] This design would improve the disease resistance of ill pigs, health status of weak pigs and management level of pig populations. This study would also provide a basis for the healthy running of large-scale fattening pig house with fermentation bed. Conclusion] The pig-raising model with fermentation bed would improve the environment of pig house and the welfare of pigs. In addi- tion, the performance of pigs and quality of pork were also improved. The fermen- tation bed had an obvious advantage in safety and economics, and it had
