Blood BHB
Monitoring of the cows metabolic activity and detection of ketosis by infrared spectroscopy
Why predict Blood BHB instead of Milk BHB?
Milk BHB is unstable and levels very low
Milk BHB content will decrease rapidly if the milk is not stored at 4°C right after milkingSlide14
Blood BHB
Calibration on 696 cow samplesSlide15
Blood BHB
Correlation spectrum between
Blood BHB content &
milk spectra
The spectral zone with the highest correlation are related to the milk fatty acids profileSlide16
Lactoferrin
Used for early detection of mastitis & monitoring of the sanitary status of the mammary gland
Iron binding antimicrobial glycoprotein
Plays a role in pre-immune host defense
Strong association between LF & occurrence of mastitis
Used to check sanitary status of the mammary glands in the herdSlide17
