Abstract

Analysis of data on 763 primiparous and 1214 multiparous cows in Italy, obtained between 1 April and 31 December 2004, revealed that the average incidence of twinning was 0.39 and 6.58% respectively and that of stillbirths 4.58 and 5.10%. The incidence of retained placenta, metritis, ketosis and mastitis was 3.93, 30.53, 14.2 and 0.52% respectively for heifers vs. 13.59, 29.07, 22.56 and 2.80% for cows. The average body condition score at calving was >4.25 for 1.04% of heifers and 2.37% of cows, and it was <3 for 32.11% of heifers and 43.42% of cows. An account is given of the correlations between incidence of the various diseases and body condition and of the costs of veterinary treatment. The importance of herd management is emphasised, details are given of methods of evaluating body condition scores at different times of the reproductive cycle, and suggestions are made for various hands-on methods of avoiding and detecting diseases.
