The aim of this study was to evaluate a new double-channel system for ultrasound-guided transvaginal intrafollicular treatment in cattle. The system is equipped with separate aspiration and treatment channels facilitating the aspiration of a small part of follicular fluid followed by the immediate injection of the same amount of treatment solution. In Experiment 1 an intracystic injection was performed successfully in all cows (6/6). In Experiment 2 saline was administered to dominant follicles with an overall success rate of 87.5% (14/16). This new double-channel system represents a reliable method for intrafollicular treatment preceded by an aspiration of the necessary amount of follicular fluid without an increase in intrafollicular pressure.
