Presently neither the specification of rumen cannula for small ruminants is reported nor is it commercially available in Egyptian market. Therefore, fabrication of ruminal cannula for sheep and surgical procedure for its implantation are described in this paper. The device was adapted to allow sampling of entire ruminal contents via cannulas with different diameters, which tightly sealed within ruminal fistula to ensure cleaner, achieve easier nursing of operated animals, and maintain more normal ruminal environment. The ruminal cannula was applied into the sheep by one-stage operation. It has been successfully used in 11 ram (3-5 year-old) for 16 months without problems and caused no complications.
