Research has confirmed that several diseases including E.coli scours and Joint-ill find their way into the newborn animal via the umbilical cord. Sprays and dips can also cause problems. These umbilical clamps are the solution. Simply attach as soon as possible after birth. Remove after 24 to 48 hours. Place clamp approximately 5mm from top of umbilical cord. Cut cord below clamp to prevent suckling. Clamps can be disinfected and re-used if desired or can be left to fall off naturally. Clamps are 65mm long. Sold in packs of 50.
