The William H. Miner Agricultural Research Institute has released two studies that compared six rumen-protected lysine (RPL) products for both the release of lysine over a 24-hour period in high and low moisture total mixed rations (TMR) and the efficacy of rumen protection of RPL products after mechanical mixing in TMRs. In the first study, after 24-hour exposure in TMRs with either 40 percent dry matter (DM) or 52 percent DM, only 3.8 percent of the lysine in Metabolys BY-PASS LYSINE was lost.

This data suggest that the H.J. Baker product can be used in once-daily feeding programs with minimal lysine product loss occurring.

In the second study, Metabolys BY-PASS LYSINE was placed in Dacron bags, mixed for 6 minutes in a TMR and placed in the rumen for 0, 6, 12 and 24 hours. A 13.5 percent lysine loss was reported.

The Miner Institute study supports a University of Georgia study of six rumen/duodenal cannulated cows. The results of the University of Georgia cannulated cow study for MetaboLys BY-PASS LYSINE showed 88.89 percent rumen bypass of lysine and 79.37 percent digestibility of lysine in the small intestine.

“We are honored to have the Miner Institute include MetaboLys BY-PASS LYSINE in their study and we are very pleased our product performed so well," said H.J. Baker’s Danny Wright.

"This third party research validates the performance of MetaboLys BY-PASS LYSINE." PD
