Designed to safely administer colostrum or necessary fluids to combat calf scours and dehydration, this Coburn calf oral feeder is made of non-toxic, heavy grade plastic. It has a special tear-shaped ball design that prevents the esophageal probe from being inserted into the trachea. The reusable feeder has a loop for hanging for easy administration, and the bag has a capacity of 2.5 litres (84.5 oz.).
