Inline Milk Lactose Concentration as Biomarker of the Health Status and Reproductive Success in Dairy Cows

In this study, cow reticulorumen content pH and temperature together with the activity were registered using smaXtec boluses, specially designed for animal care. Body weight, rumination time, milk fat/protein ratio, yield, lactose, electrical conductivity, somatic cell count consumption of concentrated feed by Lely Astronaut® A3 milking robots. The cows in study assigned into two groups according to lactose concentration: group 1—milk < 4.70% (n = 20), 2—milk ≥ 15). following further classified fat protein ratio: F/P 1.2 (class 1), 2) > 3). According our results, we can conclude that inline concentration be used indicate health status reproductive success fresh dairy cows. Cows an increased (≥4.70%) showed more (54.47%) had less risk mastitis (determined lower conductivity (EC) counts (SCC)) metabolic disorders, determined F/P. A higher glucose was also apparent concentration. Registered levels early identification disorders (set at SCC 100 thousand/mL). Lactose cows’ positively associated their success.
