|Cathegory||Publication in specialized journals|
One-time nationwide collection providing annual data on dairy cows’ health was used to compare the reported incidence of clinical mastitis in Czech Fleckvieh dairy cows (C) and Holstein cows (H). After editing the data, 65,000 lactations in C and 111,000 lactations in H were available. and, except for the first lactation, the same applied to lactations in cows with higher parities (2, 3, 4, > 5). Contrary to expectations, primiparous C cows had higher lactational incidence Only the first clinical mastitis per lactation (“mastitis”) was evaluated with respect to parity and days in milk. In total, H had more lactations with mastitis (C 19.1; H 22.2%, p < 0.001) rate of mastitis in the first and second month of lactation (1st month: C 8.3; H 7.1 %, p < 0.001; 2nd month: C 2.0; H 1.8 %, p < 0.05). The need for better conditions, especially for heifers before calving and primiparous cows in early lactation, mainly in C herds, is highlighted.
