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.
Ferdinand de Magellan was born about 1470 of noble parents, and probably spent his boyhood as a page of the Queen of Portugal. As a young man he was in the East India service, then in Morocco. After a slight from King Manuel, he enlisted under the Spanish king, and set forth his project for a trip round the world. The expedition set sail August 10, 1519. Magellan was killed in April 1521 at Zebu [in the Phillippines], but they had already reached the eastern edge of the known world, and his men completed the voyage to Spain. The voyage proved that the earth is round (although most educated people knew this already!).
