Summary An experiment was conducted to evaluate the metabolic products of chlorocholine chloride (CCC) in eggs and meat of laying hens fed a diet containing 15 N‐CCC. Ten brown laying hens were randomly divided into two groups of five each. One group was offered 15 N‐CCC free diet while the other group received a diet with 100 ppm 15 N‐CCC for 11 days. Samples of eggs and meat from the laying hens were collected. Egg yolks and albumen were separated. Meat was collected from the breast and femur. The metabolic products of CCC were measured using ion trap electrospray ionisation mass spectrometry (ion trap‐ESI‐MS/MS). Determination of CCC or its metabolites in eggs and meat showed that CCC was metabolised to choline. Corresponding MS/MS spectra were obtained for m/z 104 (choline) or 105 ( 15 N‐choline), whereas nothing was detected at m/z 122 (CCC) or 123 ( 15 N‐CCC). The results from this study indicate that CCC will be metabolised in tissues of laying hens.
