Abstract: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 cows raised in a commercial farm located in Northern Italy. The results highlighted that there is a significant difference both in haemoglobin oxygen saturation (SpO2) and pulse rate before and after milking conside… Show more
