The influence of lameness of holstein breed milk cows on their dairy yield
Original language description
In this project we were occupied with the influence of lameness on dairy yield of Holstein breed milk cows. Experiment was carried out in Farma Papůvka in Pňovice. 59 cows were diagnosed as having lameness. For comparison, there were 59 milk cows withoutlimping symptoms chosen by random sampling and joined to previous milk cows. As monitored parameter the actual milk yield, the fat content, content of protein and lactose were evaluated. We have found out that milk cows without lameness had average actual milk yield 14,90 kg of milk, average protein content 3,12% and average lactose content 4,67%. Unlike these, milk cows with lameness had actual milk yield 11,48 kg of milk, the protein content 3,31% and lactose content 4,92%. These differences were evaluated as highly statistically significant (P<0,01) in every cases. Only the average fat content (with healthy milk cows 4,22% and with affected milk cows 4,48%) was not statistically significant. Based on these results, we can pronounce
