Abstract

The objective of the experiment was to measure the ruminál stability of different choline sources (Procol-25®, Norcol-25®, Sintocol-25®, Reashure® as rumen-protected products and choline chloride as a non-stabilized compound). Three rumen-canulated ewes were used to assess the ruminál degradation of different choline products. Triplicates of samples were incubated fór 0, 2, 4, 8, 16, 24 and 48 hours; the washing phase was changed to tender dipping of the samples intő cold water to minimize the loss of choline. The ruminál degradation of unprotected choline chloride calculated at 12%/hour ruminál passage rate was the highest; 88.92%. The rumen protected products Procol- 25®, Norcol-25® and Sintocol-25® were degraded significantly (P<0.05) slower (69.42 and 69.51 and 83.29%, respectively) as compared to the unprotected form, bút considerable differences could be detected among them as well. The by-pass product called Reashure® showed the lowest disappearance from the rumen, only 13.85% of its choline content was degraded. The modified in situ method seems to be a quick and cost-effective way of studying the ruminál stability of different choline sources.
