牦牛瘤胃纤毛虫与其营养代谢

A Quick Detection of Salmonella in Meat by Method of SPA Assisting Agglutination

选用２０头装置永久性瘤胃瘘管的健康成年母牦牛和未装瘤胃瘘管的２２头生长期牦牛，分别于高山灌丛、高原草甸和川西平原地区，进行了牦牛瘤胃纤毛虫与其营养代谢的研究．结果表明，牦牛瘤胃液中纤毛虫在采食绿色植物时双毛虫属含量高，在牧草淀粉量增高时，均毛虫属增加，其头毛虫与密毛虫在青枯期大量增加；在高海拔向低海拔迁移的过程中，其纤毛虫消失与恢复，成年牦牛比生长期牦牛适应快；瘤胃内营养代谢物的含量，代表瘤胃代谢强度和机体对营养的需求．

A F Salmonella mult valence antitoxic serum is used to make Staphlococcus aureus allergic:1800 PCS,prepare SPA diagnosis fiuid,directly apply the method of glass agglutination to inspect Salmonella of meat,which has the following advantages:fast speed (not more than 30 hours),accuracy (inspect 100 meat samples with routine inspect method SN0170-92 at the same time,the standard rate is up to 95.24%,high sensitivity(the use of effect valence is up to 1∶64),strong characteristic (It only reacts with Salmonella and intensity is '+++'),high inspection rate (1.0% higher than common inspest method) and economization (It can save 40 yuan RMB in one meat sample).
