Identification of Risk Factors for Lameness Detection with Help of Biosensors

In this study we hypothesized that the lameness of early lactation dairy cows would have an impact on inline biomarkers, such as rumination time (RT), milk fat (%), protein fat/protein ratio (F/P), lactose (L, %), electrical conductivity all udder quarters, body weight (BW), temperature reticulorumen content (TRR), pH (pH), and walking activity (activity). All 30 lame (LCs) used in experiment had a score 3–4, identified according to standard procedure Sprecher et al. The healthy (HC) showed one. RT, fat, MY, protein, F/P, L, BW were registered using Lely Astronaut® A3 milking robots each cow was being milked. TRR, activity, contents cow’s specific smaXtec boluses. lasted total 28 days. Days “−14” “−1” denote days experimental period before onset clinical signs (day “0”), “1” “13” indicate after start treatment. We found from ninth day diagnosis laminitis until end our study, LCs higher ratios. On 3rd disease diagnosis, LC group reduced. decreased sharply second first RT HC tended decrease during experiment. also increased appearance signs.
