内容本研究的目的是开发快速和成本效益的方法，用于发情检测奶牛的近红外光谱和aquaphotomics，使用来自个体奶牛的原料奶。我们发现，在所调查的荷斯坦奶牛的发情期的牛奶中的水分光谱的方法显示出一致的特定的水光谱模式。特别是在早晨挤奶时收集的前乳中检测到特征变化。它们反映在乳汁光谱的计算水图中，其中发情期的独特光谱图案显示强氢键水的吸光度增加。结果表明，原料奶近红外光谱监测提供了一个机会，间接分析激素水平，通过复杂的生理变化所造成的水的光谱模式的变化与生育期。
ContentsThe purpose of this research was to develop rapid and cost‐effective method for oestrus detection in dairy cows by means of near infrared spectroscopy and aquaphotomics, using raw milk from individual cows. We found that aquaphotomics approach showed consistent specific water spectral pattern of milk at the oestrus periods of the investigated Holstein cows. Characteristic changes were detected especially in foremilk collected at morning milking. They were reflected in calculated aquagrams of milk spectra where distinctive spectral pattern of oestrus showed increased light absorbance of strongly hydrogen‐bonded water. Results showed that monitoring of raw milk near infrared spectra provides an opportunity for analysing hormone levels indirectly, through the changes of water spectral pattern caused by complex physiological changes related to fertile periods.
