ABSTRACT.
The ability to authenticate the feed given to animals has become a major challenge in animal production, where the diet fed to the animal is one of the most important production factors affecting the composition of milk and meat from cattle, sheep, and goats. Hence, there is currently an increased consumer demand for information on herbivore production factors and particularly the animal diet. The aim of this study was to evaluate the reliability and accuracy of near-infrared (NIR) reflectance spectroscopy as a tool to verify and authenticate the type of silage used as fed for ruminants. Grain silage (GrS, n ) 94), grass and legume silage (GLegS, n ) 121), and sunflower silage (SunS, n ) 50) samples were collected from commercial farms and analyzed in the visible and NIR regions (400-2500 nm) in a monochromator instrument in reflectance. Principal component analysis (PCA),
partial least-squares discriminant analysis (PLS1-DA), and linear discriminant analysis (LDA) models ere used as methods to verify the different silage types. The classification models based on the NIR data correctly classified more than 90% of the silage samples according to their type. The results from this study showed that NIR spectra combined with multivariate analysis could be used as a tool to objectively authenticate silage samples used as a feed for ruminants.

ABSTRACT - Although the ancient Vitis vinifera Tannat variety is virtually unknown in the international wine market, the strategy to promote it as the Uruguayan emblematic grape variety is starting to become successful in the red wines market. This paper presents a summary of the latest research and developments performed in
Uruguay with Tannat since the late 1970s, its origin and production statistics. As an expression of the state-of-the-art viticultural technology developed in Uruguay for this variety during the last ten years, the chemical characterization of the polyphenolic and aroma profiles, typical for this variety, is also presented. The high
polyphenolic content of this V. vinifera variety, when compared to other red grapes, confer its wines a high free radicals scavenging activity. Furthermore, from the
winemaking point of view, some New World wine-producing countries have planted this grape to blend it with their own varieties, with the purpose of adding more
structure and aging potential to their premium red wines. |
