Measuring oxygen saturation and pulse rate in dairy cows before and after machine milking using a low-cost pulse oximeter
The present study was aimed to measure the haemoglobin oxygen saturation and the pulse rate at teat level on dairy cows after and before milking, using a low cost pulse oximeter developed especially. The pulse oximeter has been tested during a three days of field test involving 18 Holstein Friesian...
