Most cases of colic in horses are caused by poor horse management: poor feeding habits, poor exercise and weight management, poor horse worming practices, improper care of a horses' teeth, and even improper exposure to water. Any sudden feed changes in a horses diet will almost certainly cause a horse to colic. Especially if the horse is exposed to a feed that is richer than the one they have been accustomed to eating. To avoid feed induced colic in horses, always introduce new feeds slowly, over the course of 1Â½ - 2 weeks.
In search of fame and fortune, Portuguese explorer Ferdinand Magellan (c. 1480-1521) set out from Spain in 1519 with a fleet of five ships to discover a western sea route to the Spice Islands. En route he discovered what is now known as the Strait of Magellan and became the first European to cross the Pacific Ocean.
The king accepted the plan, and on September 20, 1519, Magellan set sail from Spain in command of five ships and 270 men. Magellan sailed to West Africa and then to Brazil, where he searched the South American coast for a strait that would take him to the Pacific. He searched the Rio de la Plata, a large estuary south of Brazil, for a way through; failing, he continued south along the coast of Patagonia.
