Meta-analytical study on the performance and utilization efficiency of different methionine sources by pigs

摘要

Methionine (Met) is the second limiting amino acid in swine diets. The utilization of a synthetic amino acid for supplying this is a consolidated practice. However, the ideal level of this amino acid to optimize various criteria is still very controversial. Part of the discrepancy between studies may be linked to inter-experimental variability influencing the results. This meta-analysis is presented as a viable alternative by providing techniques that allow control of the variability, uncovering results that would not be noticeable in a smaller population. This study focused on the animal response to ingestion of different levels of methionine.
