Everything equine — from horse trailers to diamond-stud horseshoe earrings — are on display at Equine Affaire, one of the nation’s biggest expositions for horse lovers. The four-day event features 450 retailers; more than 225 classes, seminars, and demonstrations; a breed pavilion; a ‘‘musical celebration of the Horse’’ show called Pfizer Fantasia; and more. ‘‘New England in general has a very strong horse community,’’ said Angela Ryan, spokesperson for the event, which draws more than 100,000 visitors and celebrates its 10th anniversary this year. One highlight is the World Championship Blacksmiths Regional Qualifier. About 50 farriers will compete, said Julie Ridley, who helps coordinate the exposition. Some events are about craftsmanship; others are ‘‘fast and furious forging,’’ she said. ‘‘They take a straight piece of steel and make it into whatever is asked of them.’’
