AbstractFull Text

Recent research showed the usefulness of using estimated breeding values (EBV) for mid-infrared (MIR) based biomarkers in genetic improvement. A novel class of biomarkers was defined based on modelling responses of milk composition (e.g., mid-infrared (MIR) based) to stress expressed on continuous...

AbstractFull Text

The ICAR Recording Guidelines include provision for on-line milk analysis. However the guidelines are inconsistent with some of the practical realities of on-line milk analysis. Consequently, no milk analyser has been able to achieve ICAR approval to date. In the case of somatic cell count (SCC),...

AbstractFull Text

On-line somatic cell count (SCC) analysers automatically test for SCC during milking for individual cows, providing farmers with more measurements than conventional herd testing. The purpose of this study was to determine whether more frequent milk sampling increases detection of elevated SCC due...

AbstractFull Text

The number of dairy farms in the United States has seen a steady decrease from 70,375 herds in 2003 to 41,809 in 2016 while the number of dairy cattle has stayed relatively the same or even slightly increased from 9,103,000 milking cows in 2001 to 9,328,000 in 2016. Wisconsin statistics mirror the...

AbstractFull Text

Milk samples were collected from all milkings and from all the automatic milking system (AMS) and were analysed for fat, protein, lactose and SCC (n=10, 10, 7 and 6 farms, respectively). All herds were comprised of mostly Holstein cows and herd size was on average 74±15 milking cows. Data on milk...

AbstractFull Text

Managing large herds successfully on pastures presents a myriad of ever mutating challenges. In this period of extreme climatic conditions (droughts and floods) constant monitoring of many variables is essential. In spite of supplementary irrigation, grass growth can vary by as much as 300% from...
