Near-infrared reflectance spectroscopy calibrations for sorghum silage

Dubois, P.C.; Lagombra, Gregorio Garcia; Bolsen, K.K.; Harbers, L.H. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 2010-11-02)

Calibrations for near-infrared reflectance spectroscopy (NIRS) analysis of sorghum silage and sheep feces samples were developed. with mixed success. For sorghum silage, the standard errors of calibration (SEC) and ...
Predicting nutritional composition of corn grain using near infrared reflectance spectroscopy

Lagombra, Gregorio Garcia; Harbers, L.H. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 2010-11-02)

Corn grain samples collected over several years were used to develop equations for dry matter, crude protein, crude fiber, and ether extract (crude fat). Two computer models were used to select samples having a range ...
A rapid method of analysis of corn grain for dairy cattle

Lagombra, Gregorio Garcia; Malvetti, R.; Harbers, L.H. (Kansas Agricultural Experiment Station, 2012-09-07)

Calibration equations for near infrared reflectance spectroscopy (NIRS) have been either purchased from the manufacturer or developed in the laboratory. Comparative analysis with standard laboratory procedures indicate ...
Utilization of near infrared reflectance spectroscopy for prediction of the nutritional composition of beef and pork samples

Lagombra, Gregorio Garcia; Harbers, L.H.; Velazco, J.; Morrill, J.L.; Maziya, B.B.; Harbers, C.A.Z. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 2010-10-14)

Near-infrared reflectance spectroscopy (NIRS) offers the potential for rapid, low-cost analyses of meat samples. Beef and pork samples were analyzed by both standard laboratory (AOAC) methods and NIRS. Regression ...
