Continuing eco-pathological survey: 6. Influence of zootechnical and space-time factors on some biochemical variables in the dairy cow | Enquête éco-pathologique continue : 6. Influence de facteurs zootechniques et spatio-temporels sur quelques variables biochimiques chez les vaches laitières

1986

Several hundred of blood samplings were performed on dairy cows in four French departments, from 1978 to 1982. They were used to analyse the effect of eight factors on the physiological variations of twelve biochemical variables.
