Introduction: In the present study the ante partum ruminating behavior and the later birth course were examined. Between May 2016 and April 2017 all cows, on a North German farm with 430 Holstein Friesian cows, were equipped with a transponder recording the ruminating behavior at least one week before the calculated date of birth. In total, 28 births could be monitored. Regardless of the course of birth, a decrease in ruminal activity was observed in all animals in the days before birth. The most significant decrease was on the last day before the birth. A significant difference occurred only at certain times. The present study confirmed an association between the early decline in ruminal activity and any imminent -dystocia. Further and in-depth studies are needed to create an appropriate algorithm.

Objective: To describe the use of continuous electroencephalographic (EEG) monitoring for management of status epilepticus (SE) in dogs and cats., Design: Retrospective study., Setting: University teaching hospital., Animals: Ten patients (7 dogs, 3 cats) with SE of differing etiology (idiopathic epilepsy, n=3; toxicity, n=4; meningoencephalitis, n=2; undefined, n=1)., Interventions: The EEG was recorded continuously from 5 stainless-steel needle electrodes inserted SC. Animals were treated with diazepam and phenobarbital followed by either propofol (n=3) or pentobarbital (n=7) as a continuous rate of infusion., Measurements and Main Results: Clinical seizures stopped after induction of anesthesia in each animal. The EEG, however, still showed distinct epileptiform patterns (spikes, polyspikes) in all animals. Paroxysms were suppressed by increasing the infusion rate of either pentobarbital or propofol. A burst-suppression pattern was achieved in 5 animals. EEG epileptiform activity reappeared in 4 animals when attempting to taper the dose after >6 hours of anesthesia. This was interpreted as ongoing EEG seizure activity and an increased risk for clinical seizures, and the anesthetic dosage was adjusted accordingly., Conclusion: Continuous EEG monitoring appears to be a useful tool for therapeutic monitoring of SE in dogs and cats. It allows the detection of EEG seizures without the appearance of clinical seizures. Further investigations with blinded investigators and homogeneous animal groups to define therapeutic endpoints are warranted.
