- Abstract
The ingestion of foreign bodies, mainly metallic (MFB- metallic foreign body), by cattle is frequent and can lead to death. For diagnostic purposes, reticular pain tests are routinely used, andferroscopy is still unusual, even as a diagnostic aid. The objective of this study was to validate the application of the GMS120 Professional BOSCH® metal detector (MD) in the detection of MFB in the bovine species and describe its use infield cases. Fifty MFBs of varying shape, size, and weight were evaluated with an MD, initially on a flat and inert surface, and then in a permanent rumenfistidated cow. Retrospectively, a database from 2000 to 2017 with 122015 cattle was accessed, of which 31865 were examined after the introduction ofMD usage in 2013. Fifteen cows positive for reticular pain tests were prospectively evaluated and eight cows were diagnosed with MFB through MD usage. The mean distance for MFB best detection on the inert surface was 4.6 cm. In the fistulated cow, it was not possible to detect any MFBs, regardless of the size or weight of the material. The MFB detection capacity increased withMD use, which can be considered a diagnostic aid in specific situations. Depending on the body condition of the bovine, false negatives may occur with the use of GMS 120 Professional Bosch® metal detector.
