Path analysis and multiple logistic-normal regression were used to model the interrelationships between stated herd management practices and herd 30-d postpartum incidence rates of dystocia, retained placenta, and clinical postpartum metritis, cystic ovary, milk fever, ketosis, left displaced abomasum, and mastitis. Management risk factors were obtained from a personal interview questionnaire. Data were from 2141 multiparous Holstein calvings from May 1981 through April 1982 in 32 commercial herds in the vicinity of Cornell University. Farms where the stated policy was to administer low calcium diets to the dry cows experienced more dystocia and retained placenta. More dystocia was experienced on farms where the stated policy was to administer extra vitamin D to dry cows, where dry cows were housed with the milking cows, or where calving occurred in maternity pens rather than stanchions. There was an increased likelihood of milk fever and left displaced abomasum on farms on which the stated policy was to lead feed. Farms where dairy farmers treated cases of retained placenta had more retained placenta than farms on which the treatment was done by the veterinarian. Farms reporting the practice of feeding the cows to increase their weight during the dry period had increased odds of ketosis.
