X-rays of gizzard contents are more accurate than either X-rays of whole gizzards or manual examination of contents. Manual examination missed 24% and X-rays of whole gi71ards missed at least 28%. The most accurate technique appears to be X-ray of contents with manual verification of all positive X-ray signatures.
