Practical, easy-to-use tool helps save calves. Simple one-person operation requires no training. Durable gallon tube fluid feeder with thumb regulated vent for desired air pressure. Probe permits one-handed administration of colostrums and life-saving fluids to newborn calves. The probe crimps at the neck to stop the flow while the user inserts the esophageal tube, a feature designed to help prevent accidental insertion into the trachea. The semi-flexible bottle is then turned upright and fluids flow into the calf. Convenient handle.
