RAPID BACTERIAL-BASED BIOASSAYS FOR QUANTIFYING METHIONINE BIOAVAILABILITY IN ANIMAL FEEDS: A REVIEW

摘要

Animal and digestibility assays are the current method to quantitate methionine bioavailability. However, in addition to the costs, the variability and the time response can be hindered by a variety of factors. Ultimately, there is considerable need to develop and to optimize rapid, inexpensive in vitro assays to accurately and consistently measure the amount of digestible methionine that exists in feeds and to correlate them with in vivo assays. Attaining these objectives will allow for an inexpensive and rapid methionine assessment and will ultimately enable a timely assessment of the nutritional profiles offeedstuffs.
