RESUMO
A double blind randomised clinical trial was performed to assess the effects of oxytocin on the duration of placental retention following dystocia. If the placenta remained attached to the uterus immediately following assisted delivery of a calf, and was not expelled in the period taken to complete the protocol, an intramuscular injection of either 3 ml (60 USP units) of oxytocin or 3 ml of 0.9 per cent physiological saline was given to the cow. Each farmer was asked to observe the cow to determine the time of placental expulsion. In 55 cases available for analysis there was no significant difference between the treatment and control groups for percentage of placental retention at days 1, 2 or 3 post partum.

Multiple contrast injections were necessary in 65% of the 140 epidural venograms performed at the Penobscot Bay Medical Center between January and December 1977. Several examples of the value of multiple injections are illustrated. Institutions interested in performing epidural venography or those performing the examination on a limited basis should be aware of the need for multiple injections, allowing time for reviewing the initial series of radiographs, for reloading the film changer and injector, and for repeating fluoroscopy and catheter manipulation.

We used discriminant analysis to assess the indicants most useful in predicting whether a cow had coliform bacterial mastitis. One hundred and twenty-nine mastitic cows were divided into two groups, namely those with milk cultures that yielded pure or mixed gram negative organisms, and cows with other organisms or negative culture. Of 21 indicants examined by discriminate analysis only a history of previous mastitis in the affected quarter, weakness, clear or white color of milk, swelling of the udder, water consistency of the milk, lack of previous mastitis in other quarters, lack of palpable udder abscesses, and elevated body temperature were significantly associated with coliform mastitis. Using these variables 78% of cases were correctly classified.
