A number of metabolism crates for the separate collection of faeces and urine from sheep have been described by various workers. These fall into two main categories, collection of excreta by bag and funnel of the pattern described by Raymond, Harris and Harker (1953), and separation without harness by the use of wire screens which deflect the faeces into a container and permit the urine to flow through a metal funnel into a collection bottle. Bratzler (1951) has described in detail a metabolism crate of this latter type which has the advantage that it can be used for sheep of either sex.
