青贮饲料近红外光谱分析模型转移研究（Calibration Transfer of NIRS on Silage by Slope/Bias and Local Centering Technique）
青贮饲料 近红外光谱 模型转移
2009/8/11
为了探讨青贮饲料的近红外光谱（NIRS）分析模型在不同类型光谱仪器之间的转移，以傅里叶变换型近红外光谱仪Nicolet ANTARIS作为主仪器，光栅型近红外光谱仪FOSS 6500作为从仪器，采用斜率/截距和局部中心化2种方法进行了研究。结果表明，经斜率/截距和局部中心化法转移之后，所建立校正模型的决定系数R2和交互验证决定系数R2cv均大于0.85。采用斜率/截距法转移之后，ANTARIS仪器...
Synthesis of Microbial Protein in Ruminally Cannulated Cows Fed Alfalfa Silage, Alfalfa Hay, or Corn Silage
ruminal synthesis of microbial proteins nitrogen-15 alfalfa forage

Six ruminally cannulated cows were used in an experiment with a 3 x 3 Latin square design. Three all forage diets—alfalfa silage, alfalfa hay, or corn silage plus 2.2% urea (DM basis)—were fed for ad ...
The Effect of Preservatives Based on Propionic Acid on the Fermentation and Aerobic Stability of Corn Silage and a Total Mixed Ration
silage propionic acid preservative aerobic stability
2008/7/18
For 3 successive yr, whole-plant corn was ensiled in laboratory silos with low percentages of silage preservatives, the primary active ingredient of which was propionic acid. Preservatives were added ...
