Data used were body weights and physical measures on hip height, body depth, chest girth, hip width, and body length taken at an experimental dairy herd of three breeds (Holstein, Jersey and Danish Red). Random regression mixed models were used to ev

Records on milk yield, body weight, feed intake, SCC, mastitis incidence, and indicators of body composition were analysed both as repeated measures within lactations and as aggregated lactation measures. The data comprised 603 lactations on 293 dair

Field estimates on gross efficiency were obtained from intake and production data on 30 pluriparous Holsteins cows during wk 5, 7, 6, 11, 13, and 15 postpartum. Energy intake and efficiency from the energy chamber on the same cows were measured durin
