| Data from a 12-year longitudinal study was used to compare reproductive performance (RP), general animal health, and longevity in conventionally managed dairy cows and organically managed dairy cows. All cows were held at the same farm and managed by the same personnel. The management of the groups was basically alike, with the main exception being differences in feed composition and feeding regimes. Management of the organic group was done according to the Swedish standards for organic farming, which are certified by the International Federation of Agricultural Movements. The data for this study included all cows calving from September 1, 1990 to August 31, 2001; in total 154 organically and 156 conventionally managed animals. Calving-to-first... |

| Background Mastitis is one of the major threats to animal health, in organic farming as well as conventional. Preliminary studies of organic dairy herds have indicated better udder health in such herds, as compared to conventional herds. The aim of this paper was to further study mastitis and management related factors in certified organic dairy herds. Methods An observational study of 26 certified organic dairy herds in mid-eastern Sweden was conducted during one year. A large-animal practitioner visited the herds three times and clinically examined and sampled cows, and collected information about general health and management routines. Data on milk production and disorders treated by a veterinarian in the 26 herds, as well as in 1102... |

| The aim of this observational study was to compare indicators of energy balance in early lactation in organically managed dairy cows (OMC) and conventionally managed dairy cows (CMC) under field conditions. The diets of OMC and CMC differ as a consequence of the rules and principles of organic dairy farming. The study was based on clinical examinations and blood samples from cows within the range from 2 wk prepartum to 6 wk postpartum, collected from 20 organic and 20 conventional dairy farms with 3 visits at each farm. The farms were located in a southeastern area of Sweden and ranged in size from 45 to 120 cows. The blood parameters selected to reflect energy metabolism were nonesterified fatty acids, β-hydroxybutyrate, glucose, and insulin. At clinical... |
