Near infrared reflectance spectroscopy (NIRS) is used for quality component determinations in forages and grains. However, the use of NIRS to determine antiquality factors in forages has not been reported. Therefore, NIRS spectra were collected on leaf, stem, and head fractions to total 273 tall larkspur (Muth.) and 246 velvet lupine (Dougl.) samples. Total alkaloid concentrations (TAG) were determined through extraction and titration, and regressed against NIRS reflectance values from 1100 to… Expand
Determination of Ergot Alkaloid Content in Tall Fescue by Near‐Infrared Spectroscopy
TLDR
It is concluded that total ergot alkaloid content in tall fescue can be quantified by NIR spectroscopy with a calibration developed from immunochemcial data, though it may not be possible to include samples of stockpiled tall feshue if they are infected with a toxic endophyte. Expand
Monitoring nutrition in small ruminants with the aid of near infrared reflectance spectroscopy (NIRS) technology: A review
TLDR
Analysis of NIR spectra of the feces enables the accurate prediction of the chemical characteristics of the feed in stall-fed and grazing animals, and to some extent, of the botanical composition of diets at pasture, holding the potential to provide nutritional diagnoses for farmers raising small ruminant.

Prediction of the nutritional composition of the crop contents of free-living scarlet macaw chicks by near-infrared reflectance spectroscopy
TLDR
The present results established NIRS as a valid technique for the non-destructive, low-cost prediction of a variety of nutritional attributes of avian crop contents as small as 0.5-g dry weight. Expand
Prediction of phenolic compounds in red wine fermentations by visible and near infrared spectroscopy
Abstract Near infrared (NIR) spectroscopy was used to simultaneously predict the concentrations of malvidin-3-glucoside (M3G), pigmented polymers (PP) and tannins (T) in red wine. A total of 495Expand
Prediction of Composition of Broiler Chicken Excreta Using Near-infrared Reflectance Spectroscopy
Near-infrared reflectance spectroscopic (NIRS) calibrations were developed for the prediction of the content of dry matter (DM); nitrogen (N), ether extract (EE), neutral detergent fibre (NDF), acidExpand
Rapid analysis of layer manure using near-infrared reflectance spectroscopy.
TLDR
Results showed that the NIRS method could provide accurate predictions of moisture, organic matter, total N, and ammonium N concentrations, with a correlation coefficient of validation (r(v)(2)) and a ratio of SD over the root mean square error of prediction (RPD) of 0.86. Expand
Quantitative analysis of stevioside in the leaves of Stevia rebaudiana by near infrared reflectance spectroscopy
Stevioside, a diterpenic glycoside extracted from the leaves of Stevia rebaudiana (Bert) Bertoni, is a natural sweetener 300 times sweeter than sucrose. HPLC is routinely used to measure steviosideExpand

Prediction of Crude Protein, Extractable Fat, Calcium and Phosphorus Contents of Broiler Chicken Carcasses Using Near-infrared Reflectance Spectroscopy
Near-infrared reflectance spectroscopic (NIRS) calibrations were developed for accurate and fast prediction of whole broiler chicken carcass composition. The Feed and Forage Foss systems Model 5000Expand
Use of high spectral resolution remote leaf palatability of eucalypt determine folivorous marsupials sensing to trees for
TLDR
Results from this study suggest that calibration equations derived from modified partial least squares regression may be used to predict sideroxylonal-A concentration, and hence leaf palatability, of fucalyptus melliodora trees, thereby indicating that the remote estimation of habitat quality of eucalyPT forests for marsupial folivores is feasible.
