2 COMMON PROBLEMS Low resistance to heating, mixing, grinding and pelletizing are common physical-mechanical problems occurring when we use rumen-bypass methionine. It may happen that an efficient "physicalmechanical" protection does not allow a satisfying biological availability of methionine in the gut. From the point of view of biological availability, a limit can be represented by hydrogenated lipids used to coat and protect methionine. These lipids have a melting point of 60 C and are difficult to be digested. An "ideal" product should combine: high rumen bypass degree high availability in the gut mainteinance of high protection degree and rumen bypass value also during production steps like mixing, grinding and pelletizing last but not least.. competitive price SOLUTIONS The coating technology developed by SILO protects methionine in methio-by through a lipid film having high melting temperature (higher than 100 C) and a special ph-sensitive chemical structure. The special lipid structure surrounds each methionine micro-granule contained in the small sphere and protects methionine micro-granules even in case the sphere is mixed with the feed and/or pellettized. The lipid film is ph sensitive At rumen ph the lipid film of methio-by remains intact, while it breaks when the ph is lower than 5: so the methionine is made available already in the abomasum. This explains why the methionine contained in methio-by is characterized by high rumen bypass degree: 95%, and high intestinal release: 88%. SILO R&D methio-by has been developed and tested in scientific collaboration with the Università Cattolica del Sacro Cuore - Piacenza: "Nylon bags" method and Ross Cornell University method.

4 NYLON-BAGS METHOD A reliable method to determine the rumen-bypass degree and the intestinal release of protected methionine in the gut The NYLON BAGS method involves suspending nylon bags each containing a known weight of sample, on nylon string in different districts of digestive tract (rumen, abomasum, small intestine) of cows fitted with appropriate cannulae. Bags are removed at known intervals and the analysis of the content allows to determine the by-pass value of compounds in the rumen and the intestinal release of the nutrients. SILO carried out a large experimental program in scientific collaboration with the University Del Sacro Cuore in Piacenza with fistulated cows in order to optimize the rumen bypass degree and the intestinal release of methio-by.

5 DETERMINATION OF THE RUMEN BYPASS DEGREE methio-by was put into nylon bags, placed through fistulas in the rumen and removed at intervals of 0, 2, 4, 8,12, 16, 24 hours. Time and degree of methionine degradation in the rumen was evaluated. After 8 hours the bypass degree of methionine resulted to be equal to 95%. Results are shown in the figure here below. Percentage of Methionine released from methio-by in the rumen. Trial carried out with Nylon bag method by the University Del Sacro Cuore in Piacenza Release percentage Release time (hours) DETERMINATION OF THE INTESTINAL RELEASE The intestinal release of methionine in the gut of fistulated cow was evaluated with the Ross Cornell University method. The intestinal release of the methionine contained in methio-by resulted to be 88%.
